Renewable Energy and Fossil Fuels

            Is it a good idea to replace fossil fuel now or science fiction due to high cost and technological difficulties? Due to environmental problems and high cost of oil, many nations had taken actions and turned their attention to renewable energy. Some of them took a step further and set future goals on how much percentage of renewable energy they should depend in future years. Of course not all oil companies want these implementations to happened, but there are some as Siemens who has taken a revolutionary step. Inside the United States there is also controversy in whether renewable energy is good or not. This questions rise base on the economy and the government opinion. Until now, there is not a Renewable Energy Policy in the United States. However, states have the liberty to choose to implement and use renewable energy rather than the common fossil fuel. In this essay, I will explain what the future awaits on energy sources. In order to explain that, I will talk about what is renewable energy, what is the position of the United States in renewable energy sources, what the future awaits within renewable energy, and what is the position of our government in reference to renewable energy.
             First of all, renewable energy is any source of energy that does not consume the finite resources of the Earth and can be easily and quickly replenished. Wind, sunshine, geothermal heat, and wave power are typical renewables. Today, I will focus on wind energy and solar energy only. Wind energy is produced when the fast going wind turns the three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity. Wind turbines are mounted on a tower to capture the most energy. They are about 1oo feet or more above the ground to have a greater chance of faster and less turbulent wind. Wind turbines can be used to produce electricity for a single home or building, or they can be connected to an electrical grid for more widespread electricity distribution.
