Renewable Energy - Is It Too Late?

You cannot define renewable energy that easily. It is the general term used for a whole range of unconventional energy sources, so the definition has to be all-encompassing. As most experts put it, renewable energy is any energy source 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 generated from solar panels, 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 use of renewable energy is beneficial for our sadly polluted world. Wind power 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 people are not aware of the slight difference between the two. Renewable energy is essentially natural; it is the energy we can derive from the sun or wind or waves. Alternative energy, however, includes biofuels and nuclear energy sources which are not totally healthy options.

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.
