Electrical energy was one of man kinds
greatest discoveries. It has been a
fundamental key in the development of
technologies, and improvement in our
standard of living over the last three
centuries, and continues to be the most
versatile energy form know to man. Our ever
increasing hunger for electrical energy has
put increasing demands on our planets
resources. The large amount of electricity produced
today has its sources in fossil fuels, nuclear fission, water, and wind. This article will explore the different methods of electricity production.
Typically electricity is generated by
turning enormous turbines. These turbines
need a force applied to them to make them move.
There are various ways of generating the
required force.
Fossil Fuels:
Electricity is produced when the blades of a turbine are moved by enormous amounts of
water vapour. This vapour is generated by
heating a lot of water in huge furnaces. The
water is heated by burning fossil fuels such
as coal, petroleum, and natural gas. This method releases enormous amounts of carbon dioxide in the air, thus severely polluting our atmosphere.
this is one of our planets greatest
polluters, and it is important to turn to alternate methods of electricity production for long-term benefits.
Water:
Large dams are created in river systems to
form lakes. The water is released in a
controlled manner, and the force of the
flowing water spins the turbines blades,
generating electricity. Electricity generated this way helps control air pollution; however, this method of electricity production adversely affects the ecosystem in the water bodies.
Water accounts for 90 percent of the world’s electricity generated through renewable resources.
Nuclear Fission:
Yes, nuclear fission does not only make atom bombs, but also helps produce electricity. Nuclear fission causes a chain reaction where the element Uranium is bombarded by neutrons causing it to split. Every time a Uranium nucleus is split, more neutrons are released, causing more splits in the already split Uranium nuclei. The resultant chain reaction generates a lot of heat which is used to heat water the vapour of which eventually moves turbines to create electricity.
Bio-waste:
With technological advancements, electricity is also being produced by bio-waste. Bio-gas is a typical way of generating electricity in rural areas in countries like India. In fact, a new technology evolved in the state of Bihar in India that uses human waste to generate electricity.
Wind:
Electricity is produced when wind energy is converted to electrical energy. Wind mills or wind turbines are used to churn up enormous amounts of wind energy which is then converted into electrical energy.
Wind energy is considered by many to be our
best opportunity for producing large
quantities of clean electricity in a
sustainable manner. Most governments around
the world are starting to invest in wind
energy solutions, with a number of cities
already being powered by this green energy
source.
But wind energy isn't just for governments
to invest in. You too can use this
technology on a smaller scale for you own
electricity needs. With the help of a good
Wind Turbine
Construction Guide you can harness this
free energy source at home, saving you and
your family hundreds of dollars every year,
and helping our planet move toward a
cleaner, greener future.
