Canada's Kyoto Withdrawal May Trigger EU Tariffs


A majority of Canadians are disgusted today by the fact that our government has pulled out of the Kyoto Protocol.  Canada was one of the first countries to sign on to the Kyoto Protocol, and now as the distinction of being the first to formally back away from its commitments. 

There is much outrage and finger pointing between our political parties about whose fault it is that we have come to this point.  Frankly, I think all political parties bare some of the blame, but most importantly so does every Canadian, regardless for whom you voted. 

While it was briefly mentioned on CBC’s The National tonight, there has been very little coverage about what this could mean for Canada economically, especially regarding international trade.  There is a very real chance that tariffs could be applied Canadian products in the near future because we are no longer part of a climate pact or emissions trading scheme.

I remember first thinking that Canada might be threatened with tariffs because of our lack of climate policy when President Obama was elected.  It seemed that the US was going to adopt hard emissions targets and, through the workings of NAFTA, Canada would therefore be forced to follow suit.

More recently, we can see who is a far more likely candidate to impose the first carbon tariff on Canadian products: The European Union.  In fact, the EU is already considering applying a tariff on Canadian produced fuels because of its higher carbon content. ( Canada Fights Fuel Standards - Gazette ).  The Canadian and Albertan governments are desperately fighting this dangerous precedent, but I would imagine that Europe of all places right now is not likely to do Canada any favours. 

While Canada has done very little over the 15 years since it first signed on to Kyoto, countries and businesses in the EU have been working hard to reduce their emissions continuously.  With budget cuts and austerity measures becoming the standard in European financial policy, it is only a matter of time before Europeans demand that countries not sharing the burden to reduce global emissions be penalized before entering their economy. 

This means that even though Canada is avoiding $Billions in fines for non-compliance in Kyoto by withdrawing, we could be facing a much steeper economic hurdle from international tariffs.  The now 190 Kyoto Countries will not stand by and give unfettered access to their economies to countries and companies that are not accounting for their carbon emissions. 

There are far more important reasons for Canada not to pull out of Kyoto, however it may be the repercussions for international trade that will first show how irresponsibly Canada is acting regarding climate change.

Solar Quiz: In which month do solar hot water systems harness the most energy?


As we reach the end of August and finally have some nice weather to enjoy in Nova Scotia, it is easy to assume this time of year has the most solar energy potential.   Sunny days are more frequent and the days are still longer than average. 

However, the answer isn’t as obvious as you may think!

While PV energy generation potential is directly proportionate to solar radiation, solar thermal energy potential also depends on the starting temperature of the cold water it is heating.  Colder starting temperatures allow for more energy to be transferred as well as the efficiency of that transfer to be more efficient (due to higher deltaT).

So far in 2011, many of the solar hot water systems installed by the team at Doctor Solar have harnessed most energy in the month of March.


While there are many variables that could contribute to this variance, the most likely cause is the temperature the cold water supply.  The amount energy harnessed is calculated by the difference between temperature of solar pre-heated water and the original temperature of the cold water supply (the status quo).  In March the cold water supply averages close to 5C, while in August it averages 21C.

Everything Old Is New Again

It seems that everything old is new again...

I started this blog back in 2007 shortly after Scotian WindFIelds Inc (SWFI) was formed. After existing on its own for a while on Blogspot, Renewable Times moved over to the SWFI website where it was updated (occasionally) for the last few years.

This week will see the launch of a new SWFI website. The folks that know a lot more about this stuff than I tell me that I should move back to the stand alone Blogspot page, so here we are.

Those of you who were on the original mailing list will start getting emails again, because it seems the feed distribution is still intact, and you all likely received an email from an old post earlier in August.

I’ve imported a few old blog posts that still seem relevant, so they won’t be lost in the website change over.

Things are certainly interesting these days in the renewable energy industry in Nova Scotia. Renewable energy is at the cusp of becoming mainstream in many ways. It is now a significant contributor to our electricity grid (~20%), there are important policies being developed at municipal and provincial levels, and residents, businesses and institutions are all starting to look to renewable energy to lower their operating costs.

That all means that there is plenty to blog about…. I’m already working on a few posts, but in the meantime, as of early this week, make sure to check out the new SWFI website at www.scotianwindfields.ca

Bullfrog "Powered" or Bullfrog "Offset"

These signs are popping up more and more. Businesses, residents and events are attempting to have a greener image bysigning a contract with Bullfrog Power. According to the Bullfrog website, Nova Scotian consumers can “green” their electricity for 2cents/kWh, a roughly 16% premium.

Bullfrog came to Nova Scotia a few years ago after establishing itself as a very successful green electricity retailer. In markets such as Ontario and Alberta, electricity is produced, distributed and sold by separate parties in an open market. This allows consumers to choose from whom they buy their electricity. In Nova Scotia, we have no such option. Nova Scotia Power produces, transmits and retails over 98% of our electricity. Love it or hate it, we have no choice (unless you live in one of the 5/6 small municipal utilities, where you still have no choice, it is just not NS Power).

So, this begs the question: If Nova Scotia Power produces and sells all of our electricity, how can Bullfrog Power sell green electricity to consumers that are looking to make a difference? The answer is simple: they can’t.

What actually takes place when a consumer signs up with Bullfrog Power in Nova Scotia is that they are sold Renewable Energy Credits (RECs). RECs are produced when “green” electricity is sold in two parts – physical energy and the environmental attributes. The main reason that this is done is that in open electricity markets, physical energy and the environmental attributes are priced separately. It is somewhat similar, but not has popular or as well regulated as a carbon credit.

So, when Nova Scotia consumers sign up with Bullfrog they purchase enough RECs to offset their traditional consumption from Nova Scotia Power. This is perfectly legitimate, and ultimately a good thing. The problem is that very few Bullfrog customers understand the difference between purchasing physical energy and purchasing offsets. And Bullfrog doesn’t help increase their understanding.

I’ve thought about this issue a lot, and I’ve determined this misconception comes down to the use of the word “powered”. All Bullfrog customers get well-branded logos claiming that their home, business or event is “Bullfrog Powered”. The term “powered” implies a physical transfer of energy. In Nova Scotia, this isn’t true. The source of electricity for the consumer, and even Nova Scotia as a whole, remains unchanged. While I’m sure Bullfrog’s contracts and legalese are all completely accurate, the use of the word “powered” is misleading.

Bullfrog “Offset” would be far more accurate for their Nova Scotia customers.

This is a complicated issue, so an example might help explain it better. Airline passengers often have the chance to offset their greenhouse gas emissions associated with their flight. Carbon Credits are produced by projects such as tree planting, methane capture and renewable energy, then used to offset the emissions from burning fossil fuels to power the plane. This is very similar to what Bullfrog does in Nova Scotia. By no means could the airline claim that no emissions are coming out of their plane, they are simply being offset by a project somewhere else in the world.

Bullfrog purchases its RECs from a wind farm in PEI (which is not connected to Nova Scotia), that sells electricity into New England through New Brunswick. You’ll often hear that green electricity is injected into the “regional grid” but they fail to tell you that that electricity is then exported. To my knowledge, Bullfrog has no agreement to transfer energy into the Nova Scotia grid.

Recently, I heard a Bullfrog customer claim that green electricity was injected into the “Halifax Grid”, which couldn’t be further from the truth, and ultimately inspired me to write all this down for the record.

So, while offsetting your electricity is a good thing to do, next time you see something claiming to be powered by green electricity in Nova Scotia, unless they produce green energy onsite, tell them they should know better.
