We’re solarized

Jane and I now have solar hot water, and a tankless water heater as backup. John Cannell of J. Melvin & Associates hooked up our Navien tankless system, which is rated 98 percent efficient (our hot water tank was 55 percent efficient). The tankless is also considerably smaller than the tank, measuring at 14 inches deep, 18 inches across and 27 inches high. As you may recall the tankless system heats water on demand. The hot water tank is just that, a tank that heats water 24/7.

For a few days we relied solely on the tankless until GreenSaver returned with a plumber to hook the solar up to the tankless. We noticed that with the tankless the hot water took about 15 seconds to kick in, particularly with the bathroom sink. Oddly enough, hot water was instantaneous for the shower. However, once GreenSaver hooked up the solar, we receive hot water instantly in all faucets when the sun is out.

As I wrote earlier, the solar hot water will heat our water about 60 percent of the time (averaged out throughout the year), with the tankless unit heating water on demand when the sun is not shining.

All this took place in good time. The GreenSaver auditor returns September 10th for the second audit to determine our success in energy efficiency improvements. I just finished all the caulking inside. My last task was to lay down quarter round along the walls in the second bedroom and caulk them. That’s complete. We are now waiting on Gator Windows to replace the bathroom window with one that is Energy Star rated.


Once the second audit is done, I’ll report on how well we did in improving the energy efficiency of our home.

solar + tankless hot water = fun + eco-chic awesome

First, a few super easy calls to action

Support Wind Power - If you live in Ontario, I encourage you to tell the provincial government that you support wind power. The government is considering a 5km exclusion zone for off-shore wind power. This would kill any attempt to install wind turbines in Lake Ontario. The province is open for comments until Aug 24. Please visit the Toronto Environmental Alliance’s website for more information and a link to the provincial comment page - http://www.torontoenvironment.org/windmills/actnow

Help the People of Pakistan – Weather-related catastrophes are wrecking havoc around the world, chief of which is the mind-boggling devastation in Pakistan due to the flood. We have to kick donor fatigue in the butt, because I can tell you right now, this is a taste for more weather-related disasters to come. An easy way to give is through AVAAZ, which will direct donations to reputable relief agencies in the region - https://secure.avaaz.org/en/pakistan_relief_fund/?fp

solar + tankless hot water = emissions + dollar savings

Last week GreenSaver installed a solar hot water heater on our roof! Yes - a solar panel now sits on our roof! How cool is that!!! – Or, how hot is that, when the sun is out. When the sun is not out we will rely on our tankless water heater, which will be installed next Tuesday.

Recap – In March 2009, GreenSaver conducted a home energy audit on Jane and my house. We found out that it was 43 percent efficient. GreenSaver recommended installing a high efficiency furnace, insulating our attic and walls, caulking bulkheads and cracks, and installing Energy Star rated windows and doors and a tankless water heater. In so doing, GreenSaver estimated that we could bump up the efficiency of our house to 76 percent.

We did most of the work. We have a few last minute things to do, such as the tankless water heater. The second energy audit, scheduled for September 10th, will determine how well we did with the retrofits and instruct the government on how much grant money we will receive. Note that the federal government is no longer participating in the program, but will issue grants on audits made before March 31st.

Solar Hot Water – When I mentioned to someone that we just installed solar hot water her first reaction was that we can expect cold showers on cloudy days. Not so. The Solar Hot Water system works with either your hot water tank or a tankless system. On days when the solar panels are not generating enough heat, the hot water tank or tankless unit kicks in. You always have hot water.

The solar hot water heater reduces the need for your fossil fuel driven water heater, and can save up to 60 percent on your annual hot water heating costs. GreenSaver estimates that Jane and I will save 326 cubic meters of natural gas per year, which constitutes 16 percent of all natural gas we use annually.

Through the EcoEnergy Program Jane and I will enjoy big savings through federal and provincial grants. The governments will together kick in $2,500 to offset the $5,500 system. With an additional discount through a GreenSaver sale, we will pay only $2,500 for a system that will save us money and greenhouse gas emissions for as long as we own our house.

Tankless – Hot water tanks are heated 24/7, even when hot water is needed only briefly throughout the day. To give you a sense of hot water tanks’ inherent energy-hog nature, the efficiency of our current, and fairly new, hot water tank is estimated at 55 percent. That’s pretty piggy. A tankless hot water system heats water on demand, saving you energy and money. A co-worker confided that she has noticed no difference in quality after installing her tankless system. Once our tankless unit is in place, GreenSaver will hook up the solar hot water heater.

My friend John Cannell will hook up our tankless unit, plug up the chimney where the hot water tank was vented, and install a programmable thermostat as well. We’re almost ready for our second energy audit. I'm looking forward to seeing the new efficiency rating for our house.

The Daring Duo - Solar Hot Water and Tankless Unit

Jane and I are about to embark on the final energy retrofit before calling in the energy auditor for our final assessment. We want to install a solar hot water heater and tankless hot water unit.

A quick recap
Jane and I took advantage of the federal government’s EcoEnergy program in April 2009. An energy auditor from GreenSaver assessed our 90 year old home and rated its efficiency at 43 percent. Based on the auditor recommendations, we replaced the old furnace with a high efficiency one, had insulation pumped into the walls, attic and basement exterior header and replaced the windows and doors with ones that are Energy Star rated. I also went about caulking up the base boards and other cracks, and insulated the electrical outlets. The expected outcome is an improved efficiency of 76 percent.

The Empire Strikes Back
Regrettably, on April 1st the Conservative government ended the popular EcoEnergy program that offered incentives, matched by the provinces, to Canadians to make their homes more energy efficient.

This decision does not affect Jane and me or others who received their audit before March 31st. It just makes it difficult for others who considered participating in the program. Here’s a thought for the feds: rather than subsidize oil, provide grants to Canadians who want to make their homes energy efficient, which will stimulate local jobs. Happily the provinces are still on board to provide the grants.

The Daring Duo - Solar Hot Water and Tankless Combined!
As to the final retrofit act, I was torn. The auditor suggested a tankless hot water unit for our home. Rather than use a hot water tank that heated the water 24/7, the tankless system heats the water on demand. But I was also intrigued by the solar hot water system, which provides a savings of up to 60 percent on annual hot water heating costs. And solar is just so darn cool.

While at the Green Living Show, a representative from GreenSaver suggested I install both a solar hot water and the tankless system, and take advantage of the substantial rebates we will receive from the EcoEnergy program. How much will we save? GreenSaver’s solar hot water system and installation costs $5,500. The federal and provincial rebates at $2,500 almost cut that in half. With an additional GreenSaver promotion, the whole thing will cost us $2,500. We’d be foolish not to take advantage of this opportunity.

Meanwhile, the tankless system, which will serve as a backup to the solar system, alone can provide considerable savings on hot water as well. Prices and efficiency vary depending on the system, but the federal and provincial rebates will be up to $500.

We’re looking into getting a low interest loan through Alterna for the solar and the tankless systems and to pay off the loan in two years. The solar hot water system should last for 20 years.

Just Ask an Expert

I made a boo boo. Last week I claimed that the installation of geothermal vertical loops makes an absolute mess. What I failed to do was put this ‘mess’ in relation to other types of messes. Does it compare to the mess of the Alberta oil sands? How about coal mining or radioactive waste from a nuclear reactor?

The Best Mess
As I reported in my September 6, 2006 installment, geothermal is a green alternative to heating and cooling your home. Liquid-filled coils run horizontally out or vertically down from your house, tapping into the consistent temperature of about 12.5 C a few feet into the ground. The system draws in this temperature to cool the home in the summer and warm things up in the winter (with the furnace kicking in the rest).

Naturally, installing a vertical loop is going to leave a mess in your yard. However, this is a piece of cake to clean up compared to the waste of our current energy sources - coal and nuclear, which, in the case of the latter, will take hundreds of thousands of years to become benign.

Thanks to Greg Bonser of Village Technologies for gently reminding me that the mess generated from installing geothermal is all but a memory after the clean up. His company retrofits old buildings, helping them to become more energy efficient, and provides alternative energy solutions, such as geothermal.

Geothermal can reduce energy consumption by 25 to 75 percent, and costs between $10,000 and $20,000 depending on your home. Pay back period is between five and 12 years. With vertical loop systems you can expect the higher expense.

Greg is also looking into air source heat pumps, which according to him is “approaching the low end of geothermal heat pump efficiencies without having to drill an energy well.” Air source heat pumps, like geothermal, rely on electricity but are highly efficient. With the rising cost of gas, they may also be a more affordable alternative to heating homes.

First thing first
Make sure your home is as energy efficient as possible. If you live in an older home like me, see about getting an energy audit and prepare for the retrofits, which average about $5,000 per household. The feds will give you a rebate depending on the effectiveness of your retrofits.

According to Greg: “Making the building more efficient is always the best option. We strongly encourage our clients to do so, and are not so interested in doing equipment installs before people improve the efficiency of the building. More work and less profit for us, but a better job for the client, so that makes it more worth while for me.”

Other Notes
The other Greg – Greg Labbe of GreenSaver, which performs energy audits on homes – reviewed my May 1st blog installment and made the following comments and recommendations:
Insuladd - the non-toxic paint additive that claims to act as insulation and reduce energy bills by 20%. This, according to Greg, can be compared to claims made by sleazy traveling salesmen promoting snake oil.

Retrofoam, the foam insulation that claims to have an R-value of up to 23.7 at 2x6 studs. Says Greg: “This foam cannot be installed in a cavity deeper than 2” or the water content of the foam will cause many problems with the finishes inside the house. I hope they were not claiming they can insulate 2x6 cavities?” – Ah, yeah they were.

Pella, the ‘state of the art’ energy efficient windows? - “Pella had the corner in the 70’s on double pane windows and always used nice wood, but the windows installed in the last 10 years were dogged by supper sticky messy caulking oozing out over time and making a mess of the windows. Frankly, they are not the most high performance window on the market. For top of the line windows look for Europeans triple pane windows or locally look to fiberglass (glass is dimensionally stable over temperature and humidity ranges) with Thermotech Windows or wood at Loewen or Marvin Windows & Doors.”

The Moral of this Story
The moral of this story is to ask an expert when it comes to product recommendations. When you have an energy audit, just ask the auditor for advice on the best products out there to assist with your retrofits and alternative energy needs.

Cooking with Solar

Jane and I attended Jack Layton’s Hundred Mile barbecue at Riverdale Park this past weekend. The gathering of course was to raise the consciousness of local food. The only vegetarian option available was prepared on a solar barbecue, which also heated a very nice espresso.

Let me tell you – the barbecue was nifty. We’ve been thinking about purchasing a solar element and oven and boy-oh-boy did my mouth water - not just because of the tasty dumplings that Stephen Kerr, President of Sun Baked, cooked up.

Also on display was a solar oven, a box that traps heat through mirrors that focus solar energy into the oven. Stephen explained that temperature reaches as high as mid 300 degrees Celsius. Obviously, it works best during sunny days; however it doesn’t mind a few clouds. The oven and barbecue are meant for outside. While it is possible to use the oven indoors provided it has contact with the sun, the oven works best when it’s not behind a window.

Aside from the materials used to make the oven and barbecue, as well as carbon miles to get it to your backyard, this is carbon free cooking and a perfect way to cook during the hot dog days of summer when you don’t want to heat your home. It’s also a great way to reduce your gas or electricity bill. Keep in mind, you can use it all year round – but your cooking time is greatly reduced during the winter.

For the fancy ovens and ranges you can pay anywhere between $200 and $600. Or, if you are an engineer/handy person/rocket scientist, you can make your own! Click here to find out how.

Cooking Solution for Regions in Need
A great number of people on the planet depend on wood in which to cook. In many areas this need has lead to devastating deforestation, not to mention respiratory problems for women who cook indoors. Solar ovens and barbecues are seen as powerful agents to end this dependency on wood. Solar ovens also pasteurize water, something that millions of people are in desperate need of.

Two organizations that provide solar ovens to regions in need are Solar Ovens International and The Solar Oven Society. Both are based in the United States. In my brief conversation with Jack Layton, he said that providing these ovens as international aid is one area that Canada needs to support. I agree.

Let’s Get Political

George Monbiot said something at Toronto’s Green Living Show that stuck with me. An article in the Toronto Star only reinforced what he said.

Monbiot told the conference that several years ago he traded his car for a bicycle as part of his commitment to reduce his carbon footprint. He realized though that by removing one car from the road he was only freeing up space for another to take its place. What was required was government action to reduce the numbers of cars on the road.

I believe that making a personal commitment to a carbon diet is absolutely essential. Monbiot has a point, however. To truly make a difference we need to get a little political – even if it just means talking to our elected representatives about facilitating a greener environment.

That Brings me to…the Toronto Star article, Silence on Geothermal Deafening by Tyler Hamilton. Hamilton writes about a proposal touted by the Massachusetts Institute of Technology (MIT) that the Alberta Oil Sands use geothermal, rather than natural gas, to extract bitumen from the tar sands. A report from MIT claims that using geothermal would help reduce the Sand’s enormous carbon footprint. Although when it comes to the Sand’s Gulliver-size footprint, using geothermal may mean reducing a baby toe. Or maybe a hair on a baby toe.

But geothermal is better than natural gas. The problem is that no one seems to be jumping on the idea. Ottawa is still beating the nuclear and carbon storage drums as eco-alternatives to gas.
Hamilton cites the nuclear industry’s powerful hold on Ottawa and geothermal’s non-existent public relations machine.

Which leads me to…two other Hamilton articles in the Toronto Star:
Two sides crank up heat in nuclear power debate
The Nuclear Option

Both articles speak to the nuclear industry’s powerful voice when it comes to politics and making things happen. You and I know that nuclear is extremely costly, relies on a non renewable mined element (uranium) that damages the environment, and leaves a quarter of a million year-old toxic mess. A cleaner investment would entail making buildings energy efficient, giving home owners and businesses juicy incentives to incorporate renewable energy in their buildings and increasing wind and solar farms.

That leaves you and me to write to our MPs and make a little noise.

Come on Canada. Let’s do it. Ever write to your MP or MPP before? If not, now’s the time. If you live in Ontario or Alberta it is in your best interest to bang a drum on this.

Contact your MP

Contact your Ontario MPP or Alberta MPP

Go Sacramento

I think it’s about time for a good news story. Why not? This installment will have particular appeal to those who are bummed out about the nuclear industry’s strange sect-like hold on their provincial or state government.

Sit back, relax because we’re going to sunny California – Sacramento to be exact.

Pit Stop
But before we go there, if you have time, take a pit stop in British Columbia to find out more about its hydrogen highway. Who said it was going to be impossible?

Sacramento - Way back when....
Back in 1989, the customers and owners of the Sacramento Municipal Utility District (SMUD) had it with nuclear. They voted to close the Rancho Seco nuclear facility, in effect shutting down 43 percent of their energy supply. It was a huge leap of faith.

What did SMUD do to replace the supply? It invested eight percent of its gross revenue in energy efficiency. As a consequence, peak load was reduced by 12 percent and rates stabilized for 10 years. According to Lovins and King in Fueling the Future, “had Rancho Seco operated, rates would have increased 80 percent.”

Energy Efficiency projects included:
Helping customers purchase over 42,000 super efficient refrigerators.
Planting hundreds of thousands of shade trees to reduce indoor cooling requirements (up to 40 percent). This comes with free consultation
Providing building owners a rebate for installing Energy Star sun-reflecting coating on flat roofs to reduce load on air conditioning.

Investing in Renewable Energy
With rates stabilized, SMUD invested in renewable energy facilities, including the USA’s largest photovoltaic power plant and solar home project, one the largest utility-owned commercial wind turbine project in the USA, one of two photovoltaic recharging stations in the country and two geothermal projects.

Currently half of SMUD’s energy supply comes from its own hydro, wind an solar plants and four highly efficient natural gas cogeneration plants. The other half is purchased through long-term contracts. It is currently the most diverse mix of energy sources in the USA, buffering it from instable energy prices and grids.

Spin Off Effects
- Businesses now save 10 to 19 percent off their energy bills. One struggling company which feared higher rates prior to the shift to energy efficiency was able to stay in Sacramento, preserving 2000 jobs.

- New businesses around the energy sector cropped up and with them jobs. Sacramento became increasingly more energy independent and an exporter of energy and parts.

- Computer companies such as Apple and Intel, attracted to Sacramento competitive utility rates, set up factories in town.

- Homeowners who installed photovoltaic panels, which have a 30 year lifespan, enjoy free energy after eight to 15 years of use, as well as an increase in the value of their home.

Energy efficiency is key to the success of any energy plan. It is in effect a power source in and of itself – the best investment we can make because it does not require large capital. It is the first order of business. From there, based on money saved, governments and utilities invest in transitional and renewable energy.

Why can’t my town be more like Sacramento!?!

Denmark’s Sustainability Movement

To Know About This Week

Something is definitely not rotten in the state of Denmark. Thank goodness for the Danes! Why? They’re leaders in the sustainability movement. Wind power alone supplies the country with 23% of its electricity, a huge achievement considering that figure was 2% in 1990. Biomass and waste are a significant part of their renewable energy mix as well. Despite having two of the world’s deepest coaling ports, Denmark decided to invest in renewable energy to address concerns over coal’s nasty environmental impact and oil’s market volatility.

Sustainable Company
Amidst this hive of sustainable activity, Denmark also boasts one of the top ranking companies on the Dow Jones Sustainability Index: Novozymes A/S.

Novozymes is in the business of utilizing natural-occurring enzymes in detergent, starch and food, to name a few. Enzymes are proteins that accelerate chemical reactions. In many cases, Novozymes’ enzymes substitute the use of chemicals.

Why Can’t We All Just Get Along?
Novozymes not only committed itself to sustainability, it is one of eight companies located in Kalundborg, Denmark that have formed a symbiotic relationship. We’re talking about coal-fire plants, oil refineries and the like…I mean for Pete’s sake. And here they are acting like intelligent entities making sure that their waste doesn’t go to waste.

The whole thing started in the 1980s when the local power plant sent its waste steam to Novozymes, the refinery and pharmaceutical company to improve their utilization of fuel. Any heat the plant generated later went to the greenhouse, fish farm and town residents, eliminating 3,500 oil-burning heating systems. The refinery sent excess gas to the sheetrock factory and coal-fired utility, saving 30,000 tons of coal. Fly ash from the coal-fired utility is used in road construction and concrete production. And on it goes.

This little partnership has enabled these companies to make a profit on their waste AND reduce energy and water consumption. Of course these companies are far from being ecological angels, but through their symbiotic actions they’re behaving like a little ecology. An ecology is the most sustainable process around.

Geoexchange
Speaking of all-just-getting-along, I thank Stephen Vance from Philadelphia who told me about his blog, ‘Geoexchange in the US’ (http://geoexhange.blogspot.com/). Stephen is an IGSHPA accredited installer/contractor. What’s an IGSHPA? It stands for the International Ground Source Heat Pump Association (thank God for Google). If you don’t know what Ground Source, etc etc is, think back to my installment on Earth Energy.

When I think of challenges to the alternative energy movement, I think of its low radar in the minds of homeowners, investors and many governments. Stephen writes that hair-pulling obstacles also exist within his industry itself. In particular, he finds that many people within geoexchange don’t want to consider integration with other renewable systems like wind and solar panels. This seems an obvious course of action. As I mentioned earlier, my dream home is to have a fully integrated alternative energy system taking care of most of my home’s energy needs. It would be nice to have contractors out there who understand my dream (it would be nice to have a government to make that dream affordable).

If this is of interest to you, and I know some of you are involved in the alternative energy world, I encourage you to visit Stephen’s blog to lend your thoughts.

Just Say No to Energy Waste

If you live in Toronto, mark in your calendar the St. Lawrence Centre Forum on Climate Change: From Inconvenient Truth to Political Action, September 25. Elizabeth May, Leader of the Green Party of Canada, energy guru Ralph Torrie and the David Suzuki Foundation’s Jose Etcheverry go up against Rona Ambrose, Federal Minister of the Environment.

Ms. Ambrose seems to think that it in order for Canada to reduce its greenhouse gas emissions by 60% by 2050, everyone will have to stop driving cars, flying planes, using appliances, etc. right now. Does that make sense to you? This is going to be quite the showdown. Try and get there if you can.

TO Think About This Week
Investing in solar, wind or geothermal for your home is a big venture. Something that takes planning.

Before you even consider preparing for your perfect renewable energy system, you will need to retrofit your home to ensure it’s as energy efficient as it possibly can be. After all, why invest in alternative energy when it’s only going to escape out the window, or door, or roof….?

Why let energy escape from your home in the first place?

What’s the Big Deal?
Energy efficiency is vital to reducing our carbon footprint. Our homes constitute 36% of our greenhouse gas emissions. In California, state and utility officials view energy efficiency as an energy source in and of itself. They see energy gain through reduction in energy use. Energy saved from the humble efficient refrigerator is compared to the energy supplied by a nuclear reactor, which costs billions of dollars and leaves us with 225,000 year-old waste.

Imagine if every home had energy efficient appliances or had retrofits done to ensure energy did not fly out the window.

Incentives and How it Works - Most governments and utilities in North America offer incentive programs to encourage homeowners to invest in home retrofits. Retrofits are based on the understanding that the house is a system.

You call in an inspector or auditor to assess the energy efficiency of your home. They make suggestions for improvements such as installing double paned windows, caulking up cracks, improving insulation, etc. You determine what retrofits you can afford or would like to have done and either do the work yourself or employ a retrofit expert to do so. If you like, the auditor returns to reassess your home for measured improvements.

Click here to read my rant about the cuts to Canada’s successful EnerGuide Program

Advantages

  • Lowers your utility bills by an average of 27%.
  • An effective way to reduce your greenhouse gas emissions.
  • Stops drafts, making your home for comfortable.
  • Increases the property value of your home.

Disadvantages

  • The initial costs aren’t as steep as investing in alternative energy for your property. Auditor fees are typically $300 with average work to retrofit your home running at $5,000. Good news – there are many incentive programs to offset these costs (except from the Government of Canada).

Earth Energy

I’m back. The weekend before last I attended the Green Party of Canada Convention in Ottawa. I facilitated a policy workshop and took in the speeches and the usual hoop and howler one expects at a party convention. It was fun. I felt that I was part of history in the making. I’m also very confident that Elizabeth May will take the party to the next level.

Recently I took Jane to see Al Gore’s An Inconvenient Truth. Please see this movie if you haven’t already. You’ll then realize why I email you weekly.

TO Think About This Week
Now that I’ve covered the sun and wind in my last installments, it’s about time I delve into the dark dank underworld. That’s right. This week is all about Geothermo.

Ah yes…geothermo. What is it? Our planet stores energy which comes from the sun, 50 percent of which is absorbed in the ground. Energy also comes from the Earth’s core which is several thousands of degrees Celsius. This implies, of course, that digging to China is virtually impossible.

Hot springs are a great example of geothermal. That doesn’t mean that you need to be near one, or a fault line for that matter, to enjoy the benefits of le fruit de terra. More and more are accessing low temperature resources or what’s referred to as ‘Earth Energy’ or ‘Geoexchange’ to heat their homes.

Two types of geoexchange heat pumps that heat a house’s air and/or water

Open Loop – extracts heat directly from water pumped between two wells or from a lake or stream.

Closed Loop – extracts heat using pipes buried in the ground. Circulating liquid in the pipes returns heat to a compressor unit located inside the home.

The Government of Canada provides a quick snapshot on how closed loop works. Note that you can lay pipes horizontally (if you have the space) or vertically (up to 100 metres).

What’s the Big Deal?
According to William Kemp who wrote $mart Power:
There are approximately 500,000 geoexchange installations in the United States and 35,000 in Canada. This results in an annual energy savings of approximately 4 billion kWh of electricity, which eliminates 20 trillion fossil-fuel BTUs and slashing greenhouse gas emissions by approximately 3 million tons (2.7 million tones).

Other Advantages (based on Natural Resources Canada):

  • On average, an earth energy system can save two-thirds of the cost to heat and cool with electricity – and two-thirds of greenhouse gas emissions. However, the latter depends on the source of electricity you use to run the system’s components. If you are reliant on Ontario’s dirty coal plants for your electricity….hmmm.
  • Earth energy can provide heating in winter, cooling in summer, and year-round hot water for home use. A single system performs all necessary functions and requires only a flick of a switch to reverse the unit for a seasonal change.
  • Earth energy systems provide constant low-level heat, which eliminates the need to change thermostats at night. Another benefit is the absence of draughts that are common with conventional forced-air heating systems.
  • Earth energy systems do not smell of natural gas, oil or propane furnaces. This is great for highly-insulated buildings or for people who are allergic or sensitive to yucky gases and poor air quality.
  • Because there is no combustion, earth energy systems cannot explode and there is no need to store fuel. Insurance companies often provide a discount on policies that use earth energy.
  • If you install an earth energy system in a commercial or industrial building, you eliminate the need for a flat roof and cooling towers. That allows architects to increase the aesthetic appeal of the building's design. Bring on beautiful buildings! Haven’t we suffered enough?
  • Long lasting – can perform up to 50 years or more.
  • Increase the value of your property.
  • Easy to maintain.

There are a few drawbacks:

Harnessing Wind

If you live in Toronto, or have visited the “big smoke” recently, I'm sure you've noticed the giant wind turbine at the lakeshore near the exhibition grounds.

It is currently the only large scale wind turbine in Toronto and the first of its kind in a North American city, generating enough electricity for 250 homes. Another turbine is being developed in Toronto's East Beaches.

To Think About This Week
Not all of us can fit a thirty foot wind turbine in our backyards. After all, not all of us have backyards (hardy har har). While some countries are stepping up on wind power generation (wind energy makes up 23% of electricity used in Denmark), homeowners too can get into the act….

Residential Wind Turbines (components and costs)
There are a number of types of wind turbines that home owners or businesses can purchase. Like solar, wind can feed into the grid or, in remote areas, off grid.

Turbines with Power Ratings of 300 Watts to 1 kW ($700 +)
These are user friendly turbines, typically sold at retail outlets. They can be mounted on a pipe two inches in diameter. Typically these turbine are used to charge batteries or for light seasonal loads. The lifespan ranges from 10 to 15 years depending on the turbine and climate. Appropriate for urban environments.

Turbines with Power Ratings above 1 kW to 30 kW ($4,600 +)
Suitable for large properties and rural settings. The turbine requires an 80 to 120 foot tower and someone who knows what they are doing to install it. Can lower electricity bills by 50 to 90 percent.

Regarding prices, the larger the turbine, the higher the capital cost, but the less it costs per kilowatt. Capital costs may include the turbine, tower, inverter, and shipping.

What’s the Big Deal?
Can you imagine if every household had a wind turbine? Think of the reduction in GHGs. Stress on the grid would dramatically reduce. Most would save a bundle on energy costs.

Benefits:
• Over its life, a small residential wind turbine can offset approximately 1.2 tons of air pollutants and 200 tonnes of greenhouse gases.
• Can save up to 90% on your electricity bill.
• If your turbine produces more than your home needs, you can sell it to the utility.
• No batteries needed.
• Low maintenance and long lasting, operating completely automatically.
• You can recoup your investment within six to 15 years.
• Increases property value.
• You have some control over your energy, leaving you less vulnerable to unpredictable increases in utility rates and blackouts.
• Contrary to popular believe, turbines are not noisy and do not pose a serious threat to birds.

There are a few drawbacks:
• Capital costs are high.
• Requires an area that has some wind velocity.
• More powerful systems need some space.

Here Comes the Sun

Last week I wrote about investing in sustainable energy through utility providers. This week I start focusing on alternative sources for the home.

Not all of us can go hog wild buying up solar panels, wind turbines or geo-thermo what-have-yous. These truly are big-ticket purchases – certainly for now. Keep in mind that depending on where you live there are incentives to offset costs and in time, the costs will drop (we can only hope).

TO Do This Week
This week’s focus is on solar energy. The cheapest way to take advantage of the sun of course is to hang your clothes on the line or open your blinds. One of the most expensive ways is to install photovoltaic panels on your roof. Today, people pay anywhere between $3,500 to $40,000 + to harness the sun, depending on what they want the sun to do - heat their water or house, provide electricity, or all of it.

Components and Costs

Passive Solar
Why have windows that allow energy to escape? You can buy windows that make the sun work for you thanks to special glazing. To learn more visit http://www.efficientwindows.com/. Normally energy efficient windows are 10 to 15% more expensive than inefficient ones. The investment is worth it considering the money you save in the long run.

Solar Thermal Heating System ($3,500 - $20,000)
You can meet half your home heating needs by installing solar collectors on your roof. Click on the link and scroll down to see the illustration. Costs depend on whether you want a year-round or seasonal system.

Photovoltaics - Grid Connected ($15,000 +)
PV for short. These are your rooftop solar panels. They convert the sun’s rays to electricity through silicon cells. A Utility Interactive Inverter sends excess energy from the PV panels to the utility grid – so your PVs become an electricity supplier. Conversely, when the sun’s down, the house draws from the grid.

What’s the Big Deal? – There are several attractive pluses for going solar:

• You would not be so reliant on outside energy source use, lowering your GHG emissions by up to 20 GHG tonnes a year.

• Low impact on environment – the panels are on your roof and do not take up land.

• Solar can cover up to 60% of domestic water heating needs and half electricity.

• The energy from the sun is unlimited and virtually free after the initial cost has been recovered – anywhere from a couple of years to ten or 15. You can rely on the sun even in the winter time.

• Imagine if every house was equipped with solar panels. Blackouts would no longer be an issue. Neither would nuclear power. Power to the people!

• Reliable technology with warranties from 10 to 25 years.

• Adds value to your home.

There are a few drawbacks:

• Not so great when you live in a cloudy climate.

• Costs present significant barriers. Use of silicone crystals and the purification process are expensive, as well installing the system. To top it off, the market has been slow to build. Find out if your province/state or local government offers incentives to buy – or low-interest loans.

• Make sure whoever you choose to install your system has years of experience behind them.

• Majority of solar panels still use the lead-acid battery. Not very nice to the environment. Strides are made to use AGM batteries and the true deep-cycle batteries.

Paying for Utilities? Pay Green!

Back from holidays with no West Nile virus to report I’m happy to say. This week – investing in renewable energy….

TO Do This Week
The US government has finally admitted its addiction to oil and is directing a little money to the development of renewables. The Canadian government is doing little to support renewable energy, despite mumblings on the contrary. It’s all well and good to say you support it. It’s another thing to assign money to it.

Provincial and state governments, with the support of utility suppliers, are a little more hip to the need to invest in renewable energy.

But it hasn’t been enough.

We also can invest in renewable energy. Not all of us have the time, money or know-how to invest in stocks and bonds, let alone green stocks. There are alternatives of course – your RRSPs and mutual funds for example.

Utilities - Another way is to direct your utility bills to a company that invests that money in clean energy such as wind, solar and low-impact hydro-electric. Or you can invest in green certificates.

What’s the Big Deal? – By choosing a green utility, you pay a bit more than you would with a regular utility supplier (can be $30 a month more), but your money goes towards strengthening an industry that must be the future of energy for our planet. By investing in alternative energy, you are investing in zero GHG emissions. That $1 a day is a $1 a day for your descendents.

Here is another matter to consider, especially for North Americans. Renewable energy is a growing energy. Its potential is tremendous for the economy and job creation. The global wind industry, for example, has been growing by 40% per year. Canada has incredible potential for wind power and yet .1% of its electricity comes from wind. The Canadian government would much rather invest heavily in non-renewable energy such as oil and coal than the energy of the future. Europe and US States such as California are making great waves in this area, leaving Canada in their wake.

Green Utilities

Ontario’s Quickie Consutations

I was one of over 400 Torontonians who, on Monday, attended the public consultation on Ontario’s energy future. Here are some of my quick impressions.

Wow are people frustrated. And can you really blame them? Only three days of public consultations on decisions that will affect the province and planet for decades to come. To top things off, the provincial government decided to give the go ahead on a gas-fired electricity plant on the Toronto waterfront last Friday, before the public consultations got underway.

People were pretty upset over that. Paula Fletcher, Toronto City Councillor for the east end, was one of the first to give the Ministry reps a piece of her mind. Representatives from the government included Kathleen Wynne, MPP and Jeff Leal, MPP. There were other reps, but I didn’t catch who they were. I believe that Wynne and Leal were the only politicians present.

Fletcher took exception to the fact that the government reps were there to listen and not answer questions. She then accused the government of a serious credibility problem, citing the gas plant planned for her riding, and then called the consultations a “waste of our time.”

The government’s reputation as an unbending entity was solidified when the facilitator insisted on keeping to schedule, rather than accommodate the needs and requests of the people attending the consultation. After the facilitator ignored Fletcher to speak privately to someone else, Fletcher turned to the audience and made her final argument that millions of dollars are being poured into expensive and non-renewable energy sources, such as gas and possibly nuclear, with very little financial commitment to supporting energy conservation – the most efficient way to address energy consumption.

I would say that most who attended, whether they were for nuclear or not, strongly supported energy conservation. However, the issue is this: would conservation and renewable energy (wind, solar, geothermal, etc.) be enough to support Ontario after the coal plants shut down in 2009? Some argue yes, others argue that we can’t take that chance.

It certainly doesn’t help that the government of Ontario cites the importance of energy conservation, but has given little indication of a strong conservation plan.

One woman who spoke suggested that rather than commit billions to build new nuclear plants, to use that money to give every household in Ontario energy efficient appliances.

Another urged the government to change the building code to ensure that developers adhere to the construction of energy efficient buildings (bye-bye big airy lofts).

Many people vehemently opposed nuclear power. One scientist made a tearful plea to avoid this opton. She lived 800 km away from Chernobyl when its nuclear reactor melted down. A few brave and vocal souls got up at the end and made a plea for nuclear – citing that the waste isn’t that much and can be recycled, that the technology has improved, and that bananas are just as radioactive as nuclear plants. It was also cited that Germany, Japan and California, leaders in renewable energy, are using nuclear to augment their energy needs.

Others counted by saying that it’s been documented that nuclear reactors are not as safe as is claimed. We can’t forget the severe cost overruns from the past. On a minor note, it was pointed out that these reactors employ less people than the alternative energy sector.

One man got up and said he tried to take a course at Centennial College on wind turbines, but the course was canceled due to lack of interest. Where are the awareness building initiatives? He felt the government should be helping with this.

A gentleman from Solar Co said that he was one of the consultants to the Ontario Power Authority – as they were compiling information for their report. He told the audience that they took what he reported and twisted it around. For example, the OPA report says that photovoltaic solar panels are environmentally problematic because they rely on batteries. Not so, said the guy from Solar Co.

One gentleman spoke on the history of energy in Ontario and says that implementing the OPA’s report would repeat the same mistakes from the past.

It was noted that the biggest energy consumers are business. Recently the government gave them a big energy subsidy. What’s up with that?

Finally, one man addressed the issue of our moral obligation to protect our environment and biodiversity. We can no longer think of the economic bottom line without factoring in the true costs of our actions. If we don't, the economy will truly suffer.

The government has given little indication that it will effectively support conservation and the development of a renewable energy industry in Ontario. It has expressed strong interest in investing in nonrenewable energy. If this investment is supposed to support Ontario as it works towards sustainable energy consumption, how can we reach our goal when little is invested in these areas?

Wonderful People Doing Fabulous Things

Now that I am on about electricity use, I want to let you know about Greg Kiessling, an entrepreneur in Ontario who recently started Bullfrog, a company that offers consumers a choice to pay for wind and low-impact Hydro energy, rather than nuclear and coal-fired electricity generation. For you non-Ontarians, I promise wonderful examples of wonderful non-Ontarians doing fabulous things in the very near future (there are countless examples).

I first found out about Bullfrog when I was at Grassroots, a great little eco-store in Toronto’s Annex neighbourhood. The gals in the store were quite thrilled because they just signed onto Bullfrog and are the first business in Toronto to do so. Now technically, the grid does not differentiate where the energy comes from. Alternative energy sources make up a small percentage at this point in time. That of course will change. The Grassroots gals said they were paying a bit more, but they were quite chuffed in knowing that their money was supporting local alternative energy companies. Of course, the more who buy into Bullfrog, the greater the demand for renewable energy. The feds may not want to invest in renewables, but individuals certainly can!

An article in the Jan 1, 2006 Toronto Star quotes Kiessling as saying: “Every new gram of nuclear waste we create is another gram that has to be protected. It’s one thing to download on your kids’ generation, but another to download on the next several thousand generations.”
