Well, although it sounds good when you suggest Wind power as a major source of energy I'm not convinced that it is all that practical. Even with high fossil fuel costs, wind power is really expensive because of the materials needed to keep the windmill light enough to be efficient and the large ammount of maintenance they require. On top of this windmills are very fragile and tend to have fairly low maximum wind speeds and the reason we don't see a (much) higher failure rate is because they have been placed very carefully in places which rarely deal with excessive wind-speeds; as you try to increase wind power to account for more and more energy, these windmills will be put into more hurricane and tornado zones and a large portion of them will need to be replaced every year (making them more expensive as an energy source, and less reliable).
Generally, I favour the use of Nuclear power as a replacement for fossil fuels as a source of electricity and (in particular) I favour the use of the (Canadian Designed) CANDU reactor ... The CANDU reactor is a superior design because it is cleaner, has a lower risk for any accidents, and uses a lower grade of Nuclear material (which means there is less risk of it falling into the wrong hands); the approach used in this reactor design wasn't used by other countries because it is far larger, and can not be shrunk to put into a Submarine. Whether or not we use it or not, all nuclear fuel is degrading at the same rate and will (eventually) become unusable.
I think compressed natural gas as a trasportation fuel is an interesting idea but I think the benefits of it seem greater at the moment than they would turn out to be. The main reason Natural Gas seems so cost effective is that there is little demand for it ... If you (suddenly) have 100,000,000 cars in North America switch over to Natural Gas the supply and demand of both Gasoline and Natural Gas would change enough that it would (potentially) make Natural Gas a more expensive fuel.
With all that said, it is still a much better plan than I have heard anyone in a position of power suggest ... even though I think there is only limited benefit in his approach there is still a measureable benefit.
