You cannot define renewable energy that easily. It is the general term used for a whole range of unconventional energy sources, so the definition has to be all-encompassing. As most experts put it, renewable energy is any energy source that occurs naturally and very widely.

Most renewable energy sources are dependent on nuclear power. This nuclear power comes from the sun. In a huge nuclear reaction, the sun produces energy in the form of light and heat and this reaches the earth as natural sources of energy. The sun is the ultimate source of solar power, wind power, biomass energy and so on. Fossil fuels may be categorized under biomass energy, but are limitedly available and have plenty of disastrous side effects.

There is a great renewable energy program at The US federal National Renewable Energy Laboratory which researches the latest energy saving techniques. Scientists have finally understood that energy efficiency much more effective, and NREL educates people in this field.

They work in synchronization with the big shots of the construction industry, highlight efforts towards building with renewable energy and inform producers as well as consumers about what financial gains they may make from using this form of energy. NREL also cooperates with agencies to set guidelines for buildings and other energy consuming appliances.

Renewable energy use is beneficial for the environment in the polluted world of today. Wind and solar energy are two of the most prominent types of this energy. Biofuels, geothermal energy and wave or tidal power are fast becoming popular, though some of these may potentially harm the natural world.

Is there any difference between renewable and alternative energy?

Many people are not aware of the slight difference between the two. Renewable energy is essentially natural; it is the energy we can derive from the sun or wind or waves. Alternative energy, however, includes biofuels and nuclear energy sources which are not totally healthy options.

The infrastructure of today is made for the use of fossil fuels, even though renewable energy or green energy is way more cost effective. The government has taken very few steps to make any changes and go for renewable sources of energy in a larger scale. With the present situation getting worse day by day, there must be a change pretty soon.

If we try to find one positive thing about fossil fuels it could be that we can store the energy we get from them, which is more difficult with green energy sources. Solar power, for instance, is less effective in cloudy weather. Calm days there is not very much use of a windmill. This and initial costs to get energy from these unconventional sources are still a bit high, could be a small drawback as compared to traditional earth-killing sources of energy.
