Energy

Ever wonder where all that electricity we use in our daily lives comes from? Well, there are several sources of energy here in the United States. These energy sources produce energy that is supplied to the nation’s power grid and is then distributed to cities and communities via power cables. Here in the United States, we use about 25% of the world’s total energy. Coal power accounts for just a tad under half of the total energy produced in the United States, but it is expected that number may rise significantly with the rising costs of natural gas. Nuclear power accounts for around 20% of total energy used, and the United States is the biggest source of commercial nuclear power in the entire world. Many alternative forms of energy, particularly “renewable energy” have stepped into the limelight in recent years, as concern for the environment grows. Natural energy sources such as wind and tides are “clean” energy sources that do not produce any greenhouse gas emissions, in sharp contrast to most traditional power sources. The disadvantage, at least at the present time, is that the development and implementation of natural power sources is somewhat more expensive than the traditional methods, making it difficult for it to become a big player in the power game. While it is not currently possible in most parts of the United States to purchase renewable energy exclusively, you can purchase renewable energy credits to help make a difference.
