Is nuclear energy an alternative source of energy?

Many advocates of renewable and alternative energies do not categorize nuclear energy as an alternative source because of the hazardous waste byproducts it produces, which then have to be stored. In this way, it is not a completely non-polluting energy source. However, nuclear energy produces little to no greenhouse gases, unlike fossil fuels.

What are the alternative sources of energy used by countries?

What are the barriers to the use of alternative energy?

Well, the simple answer is that alternative energy sources also tend to have common barriers to their use as widespread energy sources. These barriers include location, storage, high cost to produce and use, and inconsistent energy supply. Wind power is not a new source of energy.
