Transcript of Wind Energy, Nuclear Energy and Coal:

Wind Energy, Nuclear Energy and Coal

A Comparison:
How do they work?

Wind Energy
Wind turbines use the power of wind to spin huge turbines which in turn spins a generator to generate electricity.
COAL Fueled Energy Production
Coal can be formed in either salt water or freshwater areas that are underwater or that have become landmasses.
Coal Production

Nuclear Energy
Fission Process

Radioisotope
- atoms that are unstable due to a large mass
Radioisotopes decay over time and release energy in the place of mass.
Spontaneous fission
-a type of radioactive decay in which an isotope splits into two separate nuclei.
Scientists realized that the uranium atom also produced two or three extra lone neutrons that would cause a chain reaction.
Wind Energy is the energy of the future...
Wind vs. Coal
Wind is actually a solution to many of the problems that arise from coal.
Wind is the energy of the future...
Wind is quickly catching up to coal in price
Disadvantages of Coal
Coal is a non renewable source
Energy produced by coal is becoming increasingly expensive.
Coal is environmentally hazardous to obtain.

Decreasing number of jobs in this industry.
Coal is very dangerous to...everyone.
Wind is a renewable source of energy... wind wont ever "run out".
There is also an increasing number of jobs produced by this industry.
Helps local economies as well.
Coal:
4.8 - 5.5 Cents/kW-h
Wind:
4.0 - 6.0 Cents/kW-h
Very little environmental implications
Solution for Global Warming.
Safe for workers and for communities.
This is 21st century technology and it is going to continue to develop
But why then havn't we switched over completely to wind power???
Nuclear vs. Coal
Nuclear energy is much more efficient and powerful then coal energy.
Fission of one atom uranium= 400 000 times more energy than one atom of coal carbon
Much more uranium... it wont run out for another 100 years.
Coal creates air pollution and greenhouse gases.
Right now coal is abundant but it will run out much faster than uranium.
Nuclear power helps stop global warming
Nuclear power is very expensive.
While nuclear energy costs 11.1 - 14.5 Cents/kW-h coal only costs 4.8-5.5
So... which is better nuclear or wind?
Many people criticize wind because they "don't like the look of them" or "they give residence headaches".
Wind energy is significantly cheaper than nuclear energy
Wind creates more jobs and has less occupational hazardous.
How
ever, can w
e rely completely
on
wind
for our
energy needs?

The answer is no...
Although wind energy is the best and cleanest fuel source, it does not have the capacity to service all of or energy needs.

The main reason for this is because it cannot be reliable . Sometimes it blows sometimes it doesn't and there's no telling how hard it will blow less than a few hours in advance.
What could be done is that, if the wind stops blowing and a wind farm stops producing electricity, some other source of electricity could to pick up the slack... something like nuclear energy.
