I wrote that atomic power generation is convenient ('convenient' seems to be wrong, my friend taught 'useful' is correct) in a resent entry because I thought atomic energy creates huge amounts of electricity at a lower cost than other methods of electrical production. But now I believe this thinking may be wrong, because if nuclear power plants have accidents like the one in Fukushima, Japan, it will cause serious damage to our society.
So which methods of electrical production are better? Thermal power generation expels a lot of carbon dioxide and causes global warming. Power generation by natural energy from sourses like the sun, wind and water cost too much and their electrical output is to small. But they are less harmful to our society than other methods. I think it is important to evolve new technology to genarate power from natural resourses in larger quantities and at lower cost. So we will make a lot of electricity without big cost.
