Transcript of Wind power vs hydroelectric power

Baseload vs. peak demand
wind power
ADVANTAGES OF WIND POWER:

1. The wind is free and with modern technology it can be captured efficiently..
3. Although wind turbines can be very tall each takes up only a small plot of land. This means that the land below can still be used. This is especially the case in agricultural areas as farming can still continue.
4. Many people find wind farms an interesting feature of the landscape.

Overview of electricity generation in Ontario
Which one is used more
WIND POWER
wind power
Wind power
wind power is begin used more because they produces enough power for 330 homes and that's only in Canada. wind power is the fastest growing source in the world and they still use it because its helpful.
VS
HYDROELECTRIC
POWER

wind power
Wind power currently provides about 2% of Ontario's electricity but it is the fastest growing energy source in the world and it will be playing a major role in supplying our electricity for the future.

HYDROELECTRIC
POWER
Ontario has been using water to make electricity for over a century. In fact, some of Ontario's hydroelectric stations are over 100 years old and are still generating electricity for us today.
HYDROELECTRIC
POWER
wind power
Wind power is the air's kinetic energy or the energy that wind produces. The strength of wind power depends on wind speed and air density.
what is wind power and where did it come from?
In general, wind is air movement caused by the heating of air by the sun, and by the different densities of large air masses. There are different winds on different size scales caused by different environmental conditions.
renewable or non- renewable ?
Renewable. It is not permanently consumed so there is an endless supply of it. That is a good question because some people confuse renewable, nonrenewable, and finite. Finite means that there is a quickly replaceable supply of it, but more is not produced. For example, water. There is a limited supply of freshwater and new water can not be made, but it can be transformed from salt to fresh and precipitates through the water cycle.

HYDROELECTRIC
POWER
what is HYDROELECTRIC POWER and where did it come from?
Most hydroelectric power comes from the potential energy of dammed water driving a water turbine and generator.
Hydroelectricity is the term referring to electricity generated by hydropower; the production of electrical power through the use of the gravitational force of falling or flowing water. ...
Hydropower is a renewable resource.
Hydropower is the renewable energy source that produces the most electricity in the United States. It accounted for 6% of total U.S. electricity generation and 67% of generation from renewables in 2008.
wind turbines that generate electricity operate in much the same way as hydroelectric generating station. instead of falling water, wind turbines use the kinetic energy of blowing air to spin the blades of the turbine which are connected to a generation
hydroelectric power
1. The strength of the wind is not constant and it varies from zero to storm force. This means that wind turbines do not produce the same amount of electricity all the time. There will be times when they produce no electricity at all.
2. Many people feel that the countryside should be left untouched, without these large structures being built. The landscape should left in its natural form for everyone to enjoy.
3. Wind turbines are noisy. Each one can generate the same level of noise as a family car traveling at 70 mph.

ADVANTAGES:

1. Once a dam is constructed, electricity can be produced at a constant rate.
2. If electricity is not needed, the sluice gates can be shut, stopping electricity generation. The water can be saved for use another time when electricity demand is high.
3. Dams are designed to last many decades and so can contribute to the generation of electricity for many years / decades.
5. The lake's water can be used for irrigation purposes.
Hydroelectric power
1. Dams are extremely expensive to build and must be built to a very high standard.
2. The high cost of dam construction means that they must operate for many decades to become profitable.
3. The flooding of large areas of land means that the natural environment is destroyed.
4. People living in villages and towns that are in the valley to be flooded, must move out. This means that they lose their farms and businesses. In some countries, people are forcibly removed so that hydro-power schemes can go ahead.

well i support wind and hydroelectric power because they help the earth and humans a lot and they make our lives easier, well wind power is one of the best resource because it is renewable and it helps the earth and as you see in my presentation wind power is really important and i think wtih out its not goood.
