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.
