The challenge for renewables like sunshine and wind is that they are less energy-dense than fossil fuels and intermittent in supply. Advocates get excited about these alternatives, but we do need to estimate the extra capital and energy costs for concentrating low-density energy such as ethanol and storing intermittent energy like wind power.

Aside from the dubious origins of the Climate 90 letter, it certainly supports the Skeptic 60 claim that there is major disagreement among scientists.

An open letter to Prime Minister Stephen Harper

By paying too much, the Ontario government is encouraging inefficient power production in a way that will give renewable energy a black eye with consumers.

Wind power is coming to Ontario because our government is hell-bent on going green. ...If only we could figure out how to get energy from hot air. Then we'd have all the power we need, forever.

Energy Probe's Tom Adams' presentation to the Ontario Energy Association Breakfast Series' "Energy Policy in Ontario: Some Perspectives on the Road Ahead," on March 8, showcased a debate between Tom Adams and Jack Gibbons of the Ontario Clean Air Alliance. Tom's presentation advanced the case for "clean coal" and state of the art coal technologies and appears in full below:

This thing smells of resources from the Gaspé being used with the majority of profits heading out of the region at the speed of, in this case, electricity. It happened with the fish. It happened with the copper. It happened with the pulp and paper. Now it will happen with the wind.

Opinion on health hazards of wind powered electricity generating turbines of the commercial variety being proposed in PEC is moving from the anecdotal domain to a deeper understanding of causality. However, it should be stated that many conclusions are disputed. There is however a significant and growing trend towards caution.
