To give us a heads-up on what we need to look for from a coalition government, here are some thoughts from one of Canada's leading energy and environment consultants, Ralph Torrie.
"If we really want to bend the curve of greenhouse gas emissions, it's going to be hard work - and it's not just about being expensive.
"A lot of the things we need to do would pay for themselves. But that doesn't mean they'll happen unless we mobilize available techniques and technologies on a broader scale than we've imagined to date. It would be great to have more money, but that by itself is not going to turn the corner.
"It's no accident that president-elect Obama is talking about leading an economic recovery with green technology. In return for upfront capital investment in efficiency, you get a long-term reduction in fuel and electricity costs. And wherever energy is used, jobs get created (not just in Alberta or Ontario). They're widely distributed in communities across the nation and over a wide range of skills.
• "We need people who can pick up a hammer and do building retrofits. We need engineers, architects and highly trained and skilled professionals who can design and build the advanced technologies that will reduce our environmental footprint.
• "We need a national program of energy retrofits, which requires a financing package. That wouldn't involve government spending as much as facilitating the financing of the upfront costs through revolving loans or mortgage mechanisms that allow the cost of the initial retrofit to be spread out over time the way we do for power plants.
• "We want a program through which the federal government works with the provinces to stimulate community colleges to train the thousands of skilled workers who will be required in these industries.
•"We want a strengthening of the energy efficiency regulations in home appliances, commercial office equipment and cars.
•"We need more creative approaches to the truck manufacturing industry to improve efficiency and reduce the greenhouse gas emissions of freight transportation.
"It isn't one silver bullet or 150 things either. Ten or 12 big things need to happen if we're going to successfully hit greenhouse gas reduction targets."
