Renewable Energy - What Can I Do?
By Eric Q. Duncan | November 18, 2008
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 cooperate with the leaders of the construction industry, highlight attempts to try to build using renewable energy and give information to producers as well as consumers how they can save money by using this type of energy. NREL also collaborate with agencies to set a rule of thumb for buildings and other energy consuming contrivances.
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 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 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.
