When you use energy, the rules are very well defined. The first and second laws of thermodynamics have been well understood for well over a century, and the third for just over a century, but the subject is still viewed by most as being pretty arcane. This is a pity, both because these laws are of such importance, and because almost everyone has a fair understanding of the first and second laws, even if they think they don't. Understanding the implications of the laws is another matter.

...Petro-Canada's partner, UTS Energy, estimated deferring the upgrader would cut costs of Fort Hills by about half, to the $13-billion to $15-billion range.
"Due to several factors including costs, current commodity, equity and credit market conditions, the partners are considering deferral of any decision to construct the upgrader," UTS said in a statement.
Petro-Canada, the country's third-largest oil company, said in September that costs at Fort Hills, located roughly 90 kilometres north of Fort McMurray, Ab., had ballooned between 50% and 60% to more than $23-billion through the last year....
One of the most critical aspects of the implementation of renewable
electricity is the ability to store electricity. If a good
solution existed right now, our situation would be a good deal
easier. On the face of it, compressed air seems a likely
candidate: relatively easy to make, store and use - so what is the
problem? Why isn't it used routinely?
More Thermodynamics than You Ever Wanted to Know?
We usually speak of storing and using energy without being very
precise about what we mean. That ends forever if you take a few
chemistry or engineering courses. Thermodynamics rules everything.
|This is an update on the Wikipedia Oil Megaproject Database maintained by the Oil Megaprojects task force (Ace, Stuart Staniford, myself and many others). The database contains now more than 425 separate entries and is growing everyday. Despite the database growth, the outcome seems to become more pessimistic with time. The derived net new capacity (i.e. once depletion from existing production is included) is around 1 mbpd until 2010 with a jump at 2 mbpd in 2008 after which depletion may dominate.|
Possible future supply capacity scenario for crude oil and NGL based on the Wikipedia Oil Megaproject database. The resource base post-2002 decline rate is a linearly increasing rate from 0% to 4.5% between 2003 and 2008 then constant at 4.5% afterward. The decline rate for each annual addition is 4.5% after first year.

Canadian natural gas is important in a number of ways: It provides 17% of total US NG consumption and today contributes roughly 11% [see calc at bottom] of the energy content in a barrel of tar sands oil (which will only increase with in-situ recovery growth). By no means (conventional or unconventional), can Canada be considered to have lots of natural gas, yet, we produce more than our fair share. Accurately predicting Canadian NG supply is, of course, important for all the usual North American energy security reasons and, among others: It would be nice to know if Canadians will have NG for things other than tar sands and exports to the US. Half of all Canadian homes are heated primarily by natural gas and about 6% of Canada's electricity sector relies on natural gas, a lot of which is used as peak electricity generation.
It’s well known that Canadian conventional gas peaked around 2001, but according to a continuing trends prediction case from the National Energy Board, it doesn’t appear as if unconventional gas will be playing a big part, at least compared against 2001 peak production levels. Below I summarize some predictions for future production of Canadian natural gas and try to estimate how much of Canada's natural gas will be left over for regular Canadian citizens.

Prices are soaring, in part, because oil is denominated in U.S. dollars and the dollar declines, thanks to Washington’s overspending on wars, trade, subsidies and government budgets. Investors have also abandoned credit markets, since the meltdown due to subprime scandals in August, and put their money into solid, real assets instead. But the biggest reason prices have been soaring is that investors are now understanding the future supply and demand reality.

A long transcript of this conversation is available below the fold.
This discussion is especially relevant in Canada now because of Bill C-33 which amends the Canadian Environmental Protection Act and is supposed to be debated in the House of Commons around May 28th, 2008:
Amendments to the Canadian Environmental Protection Act, 1999 proposed in this bill allow the federal government to implement regulations requiring 5% average renewable content in gasoline by 2010. Subsequent regulations will also require 2% average renewable content in diesel and heating oil by 2012 on successful demonstration of renewable diesel fuel use under the range of Canadian environmental conditions.
Ed note from PG: I am happy to announce that TOD:C is up and running again (and I believe overdue thanks are in order to Stoneleigh and Ilargi, now over at The Automatic Earth, for their efforts here). One of the new editors is benk (and I believe you already know Khebab!).
Ben is completing his Ph.D. in Chemical Engineering in Canada. His research focuses on the fine details of solid oxide fuel cells, dealing with ceramics and long equations. He attributes his initial interest in energy to the documentary "The End of Suburbia," which he first saw about 4 years ago. Since then he has felt a duty to get the good word out. Ben has been the host of theWatt Podcast talking about various energy issues, a capacity we are exploring bringing the TOD. Welcome Ben!
To get TOD Canada rolling again, I've written a refresher on Canada's energy situation. Canada can't be ignored when it comes to energy. We are a land of plenty. Lots of land, lots of weather, lots of consumption, lots of production. Plenty can easily become scarce though and it has to be managed, and managed well. Management of our resources will be Canada's challenge in the years ahead. Unmanaged, Canada's energy consumption is close to the highest in the world and stands at 350 GJ/person, slightly more than in the U.S. and Canada's energy intensity is the worst in the G7 at 10.6 MJ per unit GDP.

Many thanks to "peakto" for his help.
The Bank of Nova Scotia says Canadians should get used to current record-high oil prices, because they'll be with us for the rest of the decade. The bank's commodities report suggests most commodities have hit or are headed to record prices, with the bank's commodity price index up 5.7 per cent over March.
High fuel prices that are consuming a growing proportion of income at Air Canada will likely hurt demand for air travel, the airline's chief executive said yesterday. Montie Brewer, Air Canada's president and CEO, said the rapid rise and volatility of fuel prices was a concern at the country's biggest airline, which is pushing ahead with plans to use newer, more fuel-efficient aircraft."The severity of it will impact customer demand. We'll see how much the customer can absorb and still plan on travelling," he told reporters after the company's annual meeting.
