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.
Nuclear power is the origin for most renewable energy sources. This nuclear power is the one from the sun. In a huge nuclear reaction, the sun creates energy in form of light and heat which we can use in the form of natural energy. The sun is the number one source of solar power, wind power and biomass energy. Many call fossil fuels for biomass energy but it’s limited and have several calamitous 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 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.
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.
What is the 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 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.
One positive thing about fossil fuels is that we can store the energy we get from them, unlike renewable or green energy sources. Solar power, for instance, is useless in cloudy weather. Unless there is 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 high, have lent it a definite drawback as compared to traditional sources of energy.
