R U Green ?? What is Green Energy??

What is Green Energy??
Green energy is energy that is produced in a manner that has less of a negative impact to the environment than energy sources like fossil fuels, which are often produced with harmful side effects. “Greener” types of energy that often come to mind are solar, wind, geothermal and hydro energy. There are several more, even including nuclear energy, that is sometimes considered a green energy source because of its lower waste output relative to energy sources such as coal or oil.

The goal of green energy is generally to create power with as little pollution as possible produced as a by-product. Every form of energy collection will result in some pollution, but those that are green are known to cause less than those that are not. Most people who advocate greener sources of energy claim that the result of worldwide use of green energy will result in the ability to preserve the planet for a longer time. Greenhouse gases, a by-product of traditional sources of energy such as fossil fuels are thought to be causing global warming, or the process of the Earth heating up at an accelerated pace.

It is not completely necessary for green energy sources to come from places like solar or wind fields, which are examples of green “power plants.” A green energy source can be a building that is designed in a way that it keeps itself cool in the daytime and heated in the night through its architectural design rather than having an  air-conditioning or a heating system. The conservation of energy through architectural design becomes, itself, a green energy source.

Similarly, many sources of green energy can come directly from the area in which the energy is needed rather than from an outside source. A residence, for example, can be covered with solar panels for the purpose of collecting energy to be used for electricity. When utilized properly, surplus energy is often produced in this manner, which can be sent back through the local power grid and used at other destinations.

One of the goals of green energy technology is to take existing fossil fuel energy technology and clean it up so it is produced more cleanly. One such case is that of clean coal technology, where scientists are trying to find ways to extract energy from coal and other fossil fuels without all of the harmful side effects. The success of such these types of green energy depend upon the ability to extract harmful by-products from fossil fuels while not only being energy efficient, but by being cost efficient as well.
