Nuclear Energy

World energy need is getting serious right now. When widely used energy sources like coal or fossil fuel are no longer sustainable, people turn to another source - Nuclear energy.

Nuclear energy is the energy produced during nuclear fission or fusion, coming from uranium. 

Because of the characristics of nuclear energy production, no carbon dioxide is released, and a lot of energy is produced.

Nuclear energy production compared to other sources

However, there are always to sides of a coin. Nuclear energy production costs a lot of money. Uranium is very hard to find, also takes thousands years to return to neutral state. There are also known and unknown risks of radiation.

Let's take Japan for example. Nuclear plants provides a lot of energy for the country and reduces air pollution. However, in March 2011, following huge earthquake, a tsunami destroyed Fukushima Daiichi reactors. Harmful radioactive chemicals were released to environment. Area around reactors were seriously contaminated. Are the risks worth the benefits?

Personally, I think we should keep using conventional energy sources until technology provides a better way to store and process nuclear waste. It's a long run...
