Green & Clean Energy


There are a variety of green and clean energy sources out there. A “green” energy source is one that does not cause pollution in our environment, and has a low carbon footprint, or emits low levels of carbon. There are also lots of sources that claim to be green and clean, when they are actually polluting our environment, such as “clean” coal plants. Below is some information on what energy sources are clean and green, and which ones are not.

Wind Turbines
Wind turbines are VERY green and clean. They take up very little space and are easy to construct. The wind blows naturally over their propellers, allowing them to harness the energy. The energy produced by the wind can then be transferred into electricity and put onto the national electricity grid to be used in homes, by factories, and by businesses. The problem with wind, however, is that it does not blow anywhere all the time. Even in very windy areas, such as the Midwestern United States, the wind is not constant, so it cannot be relied up on to always produce electricity.

Many people do not know that nuclear energy is actually very clean. It uses nuclear fuel, which has a bad reputation, but the process of generating electricity from nuclear sources is very clean. There is very little emission and it is very safe. There are over 40 active nuclear plants in the US today. The United States has not built a new nuclear plant in over 30 years, but the industry is starting to once again consider building new nuclear power generation within the next 10 years.

Hydro-Powered Dams
Water that is rushing over a hydro-dam allows for very clean energy. The water, similar to the wind, turns a turbine that converts the energy into something that can be used in homes and businesses. Water flows with the help of gravity, turns a turbine, and produces electricity to be put onto the grid. In areas where there are large rivers, such as river that passes through the Hoover Dam in the Western United States, lots of energy can be produced in a very green & clean way.

The most common way to produce electricity in the United States is by burning coal. Burning coal is not at all a clean process, but since coal is so abundant, it is an easy and cheap way to create electricity. Many coal plants, however, can also function by burning renewable biomass, such as switch grass or tree bark. Lots of coal plants are being converted into this more efficient and cleaner way of generating electricity, reducing their overall carbon footprint.

Not So Clean Coal
As stated earlier, coal plants pollute the environment. There is a new craze now to start burning “clean coal” to reduce a plants carbon output. Unfortunately, no coal is completely “clean” – so even if it is a lower carbon emitting coal, it is still polluting our environment, and thus is not green or clean.

As you can see, there are many sources of energy used to generate electricity. Some are “greener” than others, and some are more sustainable than others. Finding a diverse energy mix is going to be key to taking us into the next century and beyond.
