Re: “Geothermal energy expertise already in Alberta,” Letter, Dec. 4

In a way, I agree with the sun power concept. We still have to learn a lot to make it 100 per cent efficient.

Wind power is another issue. From a land management perspective, it makes no sense at all. That’s aside from all the other negative effects. How are we going to replace petrochemicals? How about plastics?

Our world is full of plastics for which we have no economic viable substitutes yet. Our modern cars alone are 50 per cent plastics by volume. It’ll be a long time before everybody can afford an electric car, which still needs plastic for body construction.

Too many people jump on these sometimes deceiving theories without even making an attempt at thinking them through. Of course, there is such a thing as evolution, but let it take its natural course. It has guided us for thousands of years, and will do so in the future, too. Caspar Pfenninger, Calgary
