Renewable Energy - Why Bother?

By Eric Q. Duncan

Renewable energy is not that easy to define. The definition has to be all-encompassing as it is the general term for a whole range of unconventional energy sources. Most experts mean that renewable energy is something 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.

The US National Renewable Energy Laboratory has a great renewable energy program that finds the upcoming energy saving building methods. We have realized that energy efficiency is the best way to go, and this is where people will be educated in this aspect.

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.

The use of renewable energy is beneficial for the our sadly polluted world. Wind and solar energy are two main types of this energy. Bio fuels, geothermal energy and wave or tidal power are fast becoming more popular in areas where they can be applied.

Is there any difference between renewable and alternative energy?

Many of us are not aware of the tenuous difference between the two. Renewable energy is basically natural; it is the energy we can use from the sun or wind or waves. Alternative energy, however, includes bio fuels and nuclear energy sources and some of them are not that healthy for us.

The infrastructure we have is suited for fossil fuels, even though renewable energy or green energy more cost effective. Our government has not been busy taking any steps to change things and go in for green energy sources. With the present situation worsening every day, we have to get a change really 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. - 16477
