Humanities- Wind Energy 2013
Transcript of Humanities- Wind Energy 2013
Since wind can be used to power sailboats, so it would be safe to say that wind energy was discovered by the first people who built and used sailboats. Many ancient civilizations have used sailboats as a type of transportation and the discovery of using wind as a source of energy is credited to all of them. Many of these civilizations are likely to be more than 5,500 years old.
Wind is a type of solar energy. Winds are caused by the irregular heating of the atmosphere by the sun, the irregularity of the surface of the earth, and the rotation of the earth. The flow of wind patterns are modified by the geographical features of the land, bodies of water, and vegetation. This flow of wind, or motion energy, can be harnessed by current wind turbines, and converted into electricity.
The conditions "wind energy" or "wind power" describes the process by which the wind is used to produce mechanical power or electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. Usually mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator that can convert this mechanical power into electricity to power homes, businesses, schools, and the like. Pictures Pictures By Aashka Can wind energy replace the use of fossil fuels?
By: Samin How reliable is wind energy? Why is it useful?
By: Sara Wind Energy is not very reliable, because it only works if there is wind.
Wind can only be generated using wind turbines.
Wind turbines are very expensive. Only rich countries like China, USA, Germany, Spain, UK, Italy and Canada can afford wind turbines.
It takes up lots of land.
Very noisy and ugly.
Will never replace fossil fuels. Positives and Negatives of using wind energy and who invented it?
By: Dharkann Advantages/Pros Disadvantages/Cons The wind is a free resource and is renewable
(it will never run out). It does not produce
any harmful gases like fossil fuels which
pollute the earth and contribute to
global warming. Wind turbines do not
occupy large amounts of land/space and
are available in a variety of different sizes.
This factor is an advantage as you can
purchase the size which caters to your
specific needs. Along with solar electricity,
wind becomes an a great source
and together they become a very reliable
source. Wind turbines also generate
electricity in a safe way. Wind energy cannot replace the use of fossil fuels
because wind is always needed for wind turbines
to work. What if one day there is no wind? How are
we going to then generate electricity?
The difference is that you can burn and use fossil
fuels any time you need it, but you can only use
wind energy when there is forceful wind.
The UK has started using wind energy but, a lot of
places in the United Kingdom are windy.
Wind energy would only replace the use of fossil
fuels only if there was wind every second of the day,
which is not possible. Wind is always needed for
wind energy to work, but for fossil fuels you can use
it whenever, so wind energy cannot replace the use
of fossil fuels. A major disadvantage of wind energy is its unreliability. This is because it requires
wind. Wind does not come when you need
it and the power/force of it can vary from zero force to gushing powerful winds.
Wind turbines are also extremely noisy
and people living near them often
complain about the unpleasant noises.
They are visually pleasing and many think they destroy he landscape (this is an
opinion- not a fact). Creating wind turbines
produce pollution as fossil fuels are burnt.
Wind turbines are expensive and lots of them are needed to produce a little electricity. Digging in order to secure a wind turbine may also destroy/kill wildlife and species living in the ground. Who invented the idea of using wind energy and why?
Wind energy was never invented as wind was always there. However, the idea of using wind as a source of electricity was formulated in 1888. Unfortunately Nobody knows who invented this idea.Wind was invented to bring benefits and many of the disadvantages were discovered much later. They were invented to reduce the use of fossil fuels and stop global warming from destroying our earth. NO WIND?
NO ELECTRICITY. EVERYONE REFUSES TO BUY OR USE WIND TURBINES How do wind turbines work? Works Cited Works Cited
