Many researchers believe that harnessing the power of the atom in fission reactions is the most significant alternative energy resource that we have, for the fact of the immense power that it can generate.
Nuclear power plants are very “clean-burning” and their efficiency is rather staggering. Nuclear power is generated at 80% efficiency, meaning that the energy produced by the fission reactions is almost equal to the energy put into producing the fission reactions in the first place. There is not a lot of waste material generated by nuclear fission—although, due to the fact that there is no such thing as creating energy without also creating some measure of waste, there is some. The concerns of people such as environmentalists with regards to using nuclear power as an alternative energy source center around this waste, which is radioactive gases which have to be contained.
The radiation from these gases lasts for an extraordinarily long time, so it can never be released once contained and stored. However, the volume of this waste gas produced by the nuclear power plants is small in comparison to how much NOx (nitrous oxide—that is, air pollution) is caused by one day's worth of rush-hour traffic in Los Angeles. While the radiation is certainly the more deadly by far of the two waste materials, the radiation is also by far the easier of the two to contain and store. In spite of the concerns of the environmentalists, nuclear power is actually environmentally friendly alternative energy, and the risk of the contained radiation getting out is actually quite low. With a relatively low volume of waste material produced, it should not be a difficult thing at all for storage and disposal solutions for the long term to be developed as technology advances.
