Alternative Energy Sources

Alternative energy are energy sources which are not based on the burning of fossil fuels (oil, natural gas, and coal) or splitting atoms (nuclear). It typically comes from sources that do not deplete natural resources or harm the environment, such as wind or solar power. Some examples include:

So which resource is best?

It depends. Many alternative sources of energy are still being researched and tested. Technologies are continually being developed and enhanced to improve alternative sources of energy. Not all energies are ready for mass consumption, so you have to ask the right questions to find out which energy source does the job.

Is it a renewable or nonrenewable source?
What are the capital costs of setup?
What are the ongoing operating costs?
What size of energy storage is required?
How efficient is it to produce one unit of energy?
Can it be produced on a large scale?
What is the cost to the consumer?
What effect will it have on the environment?
