Renewable Energy – What Can I Do?
Posted on Tuesday, November 18, 2008 at 6:19 amRenewable 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.
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.
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.
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.
A good thing about fossil fuels is the easy way we can store the energy we get, a procedure that is more complicated with renewable or green energy sources. Solar power, for instance, is not that effective in cloudy weather. Without any wind, that source of energy cannot be made use of. This and the fact that initial costs to get energy from these unconventional sources are relatively high, have lent it a small drawback when we compare to traditional energy sources.
