Two Problems with “Alternative Energy”
Problem 1: It doesn't allow for much expansion. A typical analysis of alternative energy supplies will frequently find that if we turn all energy production over to wind, rooftop solar, etc. and if we have magic batteries to even out the fluctuations we can barely manage to replace the present energy-supply system. If we want to bring the rest of the world up to U.S. standards, we'll need far more and if the population increases, we will need far more.
Problem 2: By the the standards of anti-nuclear environmentalists, the more effective alternative energy systems (wind with toxic battery backup, desert solar, hydroelectricity) should be shut down. They're not decentralized and have at least as much imaginary negatives as nuclear. If they can shut down nuclear energy, they can shut down nearly anything.
