Alternative Energy--A Clash of Cultures?

As wind farms and solar farms sprout up around the world, there is an increasing chorus of complaint about the impact that whirling wind generator blades will have on birds, and about the impact that large areas covered with solar cells or solar concentration mirrors will have on animals. While it is a valid question that should be asked, those protesting this move to renewable energy seem to lose sight of a larger picture.

Sure, these installations will have some impact on birds and animals (let's not forget the little bugs either). However, continuing to rely on carbon-based fuels and continuing to spew hydrocarbons into the atmosphere will also have an impact on the birds and animals--and one of those animals is us.

Personally, I believe that propagating switchgrass across the mid-west is a great idea. It basically begins the process of reintroducing native plants back into the ecology, not to mention controlling erosion on marginal lands. It also offsets the dependence on corn for ethanol production which is a good thing considering that corn is a primary food source for the world. Introducing this one "crop" back into the ecology creates an improved environment for a variety of native mid-west animals and birds. That's not a bad thing.

Introducing wind farms and solar arrays offsets the need to generate energy through coal-powered plants, one of the most polluting machines in use today. Substituting birds who can't fly certain routes for birds who can't breath seems like a fair trade off.

Substituting electric power from solar for gas burning engines in cars seems like a fair trade off to me. I imagine that many of these same arguments went on when there was a move from horse power to steam power and then gas power. I'm sure the lantern fuel providers had a problem with the "environmental" impact of electric lights. The point is that any new technology has its advantages and disadvantages. The determiner of whether that new technology will be adopted depends on demand. If there is suitable demand, it survives and thrives. If it doesn't, it dies. Adam Smith's laws of economics are still valid.

The fact is that wind energy and solar energy are taking hold simply because the cost is rapidly approaching that of traditional energy production. The difference this time is that even the individual can get in on the action. That is, the individual land or homeowner can be a power generator--either by installing their own energy sources or though leasing a energy production capability.

I suspect that it is this individual control over energy production that is the real issue, not the environmental issues.
