Renewable Energy - Is It Too Late?

By Eric Q. Duncan

Renewable energy, what could really be the right definition? As it is the general term for many different unconventional energy sources, it has to be all-encompassing. Gurus tell us that renewable energy is an energy source that we find naturally and to a great degree.

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 federal National Renewable Energy Laboratory has a good renewable energy program that researches the latest energy-saving building techniques. Scientists have realized that energy efficiency is the way to go, and this body educates people in this aspect.

They work together with the leading instances of the building industry, foreground endeavors to build using renewable energy and tell producers as well as consumers about what and how they can save money by using this form of energy. NREL also get together with agencies to set guideposts for buildings and other energy consuming gadgets.

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.

Can you tell the difference between renewable and alternative energy?

Many people don't know the fine difference between the two. Renewable energy is fundamentally natural; it's the energy we get from the sun, wind or waves. Alternative energy, however, includes both bio fuels and nuclear energy sources which are not really healthy options for us to use.

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.
