Iowa generates about 30% of its electricity from wind energy, mostly from very large windmills of the type proposed for Penn Forest Township. As I noted in an earlier post, I think we should be turning to renewable soft energy such as backyard windmills or solar panels on the garage roof. The next best thing is renewable hard energy, which takes a large capital investment, is centralized and needs a distribution system.
The Iowa windmills, which you can see from I-80, are definitely a hard energy source, but they do use renewable energy (the wind is always blowing there), they are non-polluting, and they don’t add to climate change.
Incidentally, we also saw quite an array of huge windmills in Wyoming, a state where the strip mining of coal is a major source of economic activity. Change is coming.
