CLEAN ENERGY, PRACTICAL OR NOT?

Clean energy is definitely possible but there are a number of obstacles in the way to name a few: Millions of gasoline and diesel fuel vehicles already on the road now which will last for years, and hundreds of thousands of new gasoline and diesel vehicles are still being sold. Hybrid vehicles also require gasoline, unless they are full electric plug-in vehicles. What about wind energy? It works but it does not produce much power for the land space it requires and it is unsightly for some people. What about solar power? This is only practical in sunny climates, is very expensive, requires a lot of space, and some designs require a lot of water to operate. Hydrogen gas power? It requires energy to separate hydrogen from water and there is an infrastructure problem to have hydrogen gas stations built around the country. A fuel cell vehicle? It still requires some kind of fuel to function. OK, so what are practical alternatives? Natural gas is one of the cleanest practical fuels available now. Full electric vehicles would be practical for short run trips, e.g., city driving, if we could upgrade our electric generating plants to nuclear energy or a combination of nuclear, solar, wind energy, and hydroelectric power. My vote is to go with a proven technology now: Nuclear energy.
