Lessons Learned after the Japanese Nuclear Incident
Tapping energy from the nuclear energy resources is, so far, the best way to tap energy among the non-renewable energy resources (see "Is Nuclear Energy a Renewable Resource?"), but in the event of natural disasters like the one at Japan, things can go wrong and cause damage of a very large degree.
In case of damages to thermal power stations, the damage may happen just to the building, which can be constructed again in a matter of months, but when a nuclear reactor is damaged and the radiation leaks out of the reactor, a few kilometers of land in the surrounding area can become so highly contaminated with radiation that the entire region may be rendered useless for decades to come.
After this incident, various countries that have and are building nuclear power reactors have been exposed to the fact that when it comes to mother nature, anything can happen. Therefore these countries have started to spend more on research and development on making the nuclear reactors safer when disasters like above occur.
Also there is a rise in switching over to renewable energy resources that cause no pollution and in the wake of disasters, only the property is damaged.
