Summary:
Today, we can't do without energy, and it's demand is increasing. However there are two big problem. Coal is limited energy source, and producing energy causes global warming. There are ideas that experts argue to solve it. Some company invented the material that collect CO2, or some electricity company injects their carbon dioxide emission into the deep ground. The ideas that change energy source are using sun light and biological energy. Energy from biotechnology is developing, but it need enormous money. Solar photovoltaics become to be practical, but it also cost a lot, so that's company researches on the cutting down the cost of solar panel. Some experts insist that we should use a nuclear power generation more because that discharges less carbon dioxide emission, and there is safer one now. We can also solve the problem to reduce our wasting energy. It saves money and nature.
I listened to this video for two hours
Personal comment:
I chose this video because environment problem become serious now, and we must not ignore the problem because we live with the nature. This video show me the various possibilities of solutions for the energy problem. One of them supports nuclear energy generation, but I firmly against it. It isn't because Japan had terrible disaster. It just because that has potential danger. We don't find good solution for disposal yet. Though the supporter use the reason that nuclear energy generation discharge less carbon dioxide, some surveys showed it's same as thermal power generation if it includes all processes. They use the global warming movement for reason. We also must not forget that most countries which have nuclear power support the nuclear power generation. It is suspicious. I think disagreement of nuclear energy and saving energy are most important now.
