People around The U.S are asking all sorts of questions about renewable and non-renewable energy. There are so much to learn about energy, I don't know where to start. Lets start with the two basic questions, "What are evironmental defenders?" and "How Do You Become An Ecologist?" Being an ecologist is really simple. During your high school year you would want to take chemistry, biology and mathmatics, but be sure to include some advanced classes. Even take classes that emphasize various types of career writing. You wanna be sure to talk to your guidence councelor about what might be the best that compliments your ecological instrests. Also ask for catalogs of colleges known for ecology majors. Become Proficient with the scientific and mathmatical software used by ecologist. Plan to take interships that will give you a variety of the much-needed field experience and decide if you would like your masters degree to be in ecology or a specific science. You could even go to school to be an environmental defender. The Environmental Defender Law Center (EDLC) works to protect the human rights of individuals and communities in developing countries who are fighting against harm to their environment. The EDLC identifies cases where these environmental defenders need and want legal assisstance, and then enlists lawyers from premier firm laws to work on their behalf.

Oil, coal, natural gas, And uranium are sources of non-renewable energy. Oil is the main source of the worlds energy. There are about 3000 products made from crude oil. Other than fuels such as petrol, diesel, crude oil is used to make products including: ink, crayons, bubble gum, eye glasses and other products. Oil also belongs to fossil fuels, together with coal and natural gas. Oil was formed 300 million years ago and it had been used for more than 5000 years. It could be found underground in areas of rock that are porous and contain the oil within the rockl itself. Oil is even made in clothes, fertilizers and a bunch of ther products too! But it emits dangerous green house gases which causes global warming. And if we keep using oil; it will one day run out so we need to find alternatives in years to come. Coal is by far the most abundant fossil fuel on earth! Coal is the product of plants, mainly trees that died tens or hundreds of millions of years ago. Coal came from underground mines and now there are a large number of opencast mines. India has 7% of the worlds proven coal reserves. Coal even supplies more than 50% of the countries requirement rates. All machines run on some form of energy. Some of these such as fossil fuels causes harm to the environment.

Solar energy is one of the cleanest forms of energy. It is better for the environment than traditional forms of energy. With solar energy, you could use it to heat swimming pools, produce lighting for in/outdoors, power cars, for attic fans, calculators and other small appliances. With every year that goes by solar energy is becoming more popular worldwide. In the year 2010 we all saw an increase in solar energy installations globally of 139% compared to the year 2009. Solar is better than necular. Even though necular is concidered safe energy. There are still three safety issues that are concidered to make necular safe. One safety issue is that Controlling the rate of reaction so that it does not get unmanageable. If the rate of reaction is uncontrolled, the reaction cannot be contained such as in a meltdown and the outside environment will be exposed to high levels of radioactivity. After that then Managing the exposure to radioactive materials used in the reactor. This is necessary during the extraction, concentration, transport, storage and disposal stages, but is most important at stages after concentration, as the radioactivity levels are higher and last security of the material in some of these concentrated states, as they could be used in nuclear weapons.

Biomass offers the United States tremendous oppertunities for use as domestic and sustainable recources to provide our fuel and power. "Biomass" means any organic matter, availiable on a renewable basis. Including dedicated energy crops and trees. Argiculteral crop wastes and residues, wood waste and residues and aquatic plants as well as animal, manicipal and other wastes. The wind energy is very different than the biomass energy. And they both work differently too. The wind turbine works the opposite of a fan. Instead of using electricity to make wind kinda like a fan. The wind turbines use wind to make electricity. The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity. And biomass just uses left over crops and trees. When using the biomass energy you could preserve it or could be grown in ways that could cause environmental harm. Which one would you pick?

 

Renewable energy: is natural energy which does not have a limited supply. Renewable energy can be used again and again, and will never run out. So I say we stop using non-renewable energy and start using renewable. Go green! And renewable energy has been in use for thousands of years in one way or another. Biomass, hydro, geothermal, solar, tidal, wave, wind- These are all forms of renewable energy.
