Lets face it, Virtually all of our energy choices have big safety and environmental risks or significant weaknesses. There is no perfect or excellent energy source that has no environmental impact, is low-cost, and operates continuously. Indeed, especially in terms of the environment, our energy choices today are mostly ugly.
The two biggest renewable energy sources – corn ethanol and large hydro – pollute and damage as well. Big dams devastate fish migrations around America. Nitrogen and phosphorus run-off from corn fields that feed ethanol plants pollute rivers and cause big dead zones in the Gulf of Mexico. Though growing rapidly, wind and solar provide just 2% of America’s total energy, but even wind that causes zero air and water pollution has passionate opponents who hate its visual impacts or loath any bird kills.
