When talking about green energy, what are we really talking about? In a nutshell, green energy is energy that comes from any one of the following renewable energy sources: wind, Sun/Solar, water/ hydroelectric, geothermal, biofuels and biomass energy. There is no way that you are not going to find some form of green energy in play anywhere in the world at any given moment. This article will discuss how each renewable energy source is considered to be green energy, starting with wind power.
Although geothermal energy is not as widely used as the others are it is a green energy source; as it comes from the movement of the magma beneath the Earth's crust and from the volcanic activity all over the planet. The hot springs that have been created and kept warm all over the planet are clear cut evidence of the geothermal energy that is there for the taking.
Water/ Hydroelectric Power
There is a great deal to be said for the worldwide appeal of hydroelectric power. As a matter of fact, there are not many countries on this planet where water is not being put to use to create the hydroelectric power that is so abundant and is also a source of green energy. The only way we will ever lose this renewable energy source is if our atmosphere gets stripped away and we have to deal with the full brunt of cosmic radiation that will evaporate our water. Hydroelectric power generation is precisely why the Hoover Dam was built in the first place folks!
You've got to admit that the power that our Sun provides is another readily available source of green energy for anyone who cares to take the time to get some solar panels that will harness this nearly endless supply of the renewable energy that we, as a planet, are beginning to look to. While some solar panels are not that cheap, you can find some that are within your price range. Look at all the solar powered items on the market already!
There are two main reasons why wind power and wind mill/wind turbine generated electricity are considered to be green energy: they will not be gone any time too soon and they do not cause any more pollution to or of the environment around us. There is always going to be a wind blowing somewhere and it really does not matter whether that wind is only a slight breeze or a brisk wind or hurricane/ tornado strength winds. Wind turbines are getting more and more popular as we begin really embracing green energy as a way of life.
