No. Coal generates more than half of the energy in the United States while wind power generates less than 1%.
When talking about the amount of power (megawatts) produced, for example, the Nysted Wind Farm in Denmark has 72 turbines and a capacity of 165.6 megawatts. Assuming that 40 percent of that capacity can actually be realized, those turbines put out an average of about 66 megawatt hours in an hour. Producing enough power to account for all of what is now put out by coal-fired plants in the U.S. would require over 250,000 individual turbines.

What is wind wind energy's weakness?
The problem with wind energy is that it is usually generated via wind turbines. Wind turbines take a lot of energy to make, and unfortunately, it uses more than it will generate in it's lifetime.
Why does size matter with wind turbines?
If the turbines are much taller the ground bellow can still be used e.g. farming. The propellers can be bigger to catch more wind and make more energy.
What are the advantages of nuclear energy source?
Nuclear Energy generates a lot of energy rather than other Power Plants. One gram of uranium equals to 60 thousand tons of coal, and the energy it produce, so it is much more green (Despite the main disadvantage: explosion). The air is not as polluted as it would be with the coal. Because of the high levels of energy generation, energy cost is cheaper.
What are the positive sides of nuclear power?
It's greener and safer than fossil fuel power plants, but produces far more energy than wind or solar power plants. For example, coal power plants produce the same amount of radiation as Three Mile Island every few days, and produce extremely large amounts of particulate pollution, which kill the same number of people as Chernobyl every few weeks. Wind turbines cost about the same amount as nuclear plants, per watt, but to produce the same amount of energy, they require 300 times as much land.
How is potential energy used to generate electricity in a hydroelectric power plant?
Think about what happens in a hydroelectric plant. The potential energy in the water is called 'potential' because the water has a place to go-- down. As the water falls it gains more and more kinetic energy. What is the water made to do before it's released? It passes through huge turbines and it makes the turbines spin. It's the spinning of the turbines that generates electricity. The kinetic energy of the water is converted to electricity.
What exactly is nuclear energy?
Certain elements such as Uranium 235 and Plutonium 239 give off neutrons. When a neutron hits them, they split into two or more elements and give off more neutrons. They also give off a lot of heat. That heat can be used to boil water. The steam produced can be used to spin turbines. The turbines can spin generators and produce electricity. Burning coal, oil, or gas, can be used to produce the heat to boil water to produce the steam to spin the turbines to spin the generators to produce the electricity. The advantage of nuclear energy is that it does not produce a waste material that is released into the atmosphere.
Uranium fuel pellet used in nuclear power stations produce far more energy per kilogram than the energy produced by burning coal How much coal has to be burnt to produce the same amount of energy as?
1 kg of U-235 will produce as much energy as 1500 tons of coal
Why do people burn coal to produce energy?
Coal is less expensive than oil and will be more plentiful in years to come
What types of energy does the UK use?
natural gases, nuclear generators, cogeneration, wind turbines, coal and oil. And their are lots of renewables(e.g. wind turbines, solar panels...) possible more overall
Why do power plants rely on nuclear Energy?
To produce energy more than any other source can produce. A handful of Uranium can produce enough energy as the same as 4000 Train Load of coal [Given that each train load has around 15,000 Tons of Coal.]
Uranium fuel pellets used in nuclear power station produce far more energy per kilogram than the energy produced by burning coal How much coal has to be burnt to produce the same amount of energy?
1 kg uranium 235 = 3 000 t coal
Does Nuclear energy produce more carbon dioxide than burning coal?
No. It produces less.
What will help energy grid?
More turbines
How does coal work to produce energy?
Think of coal like wood. In a wood stove or furnace, wood is burned to produce heat. Coal contains more energy and is cheaper that wood, however wood is renewable. The large coal power plants that run use coal to produce heat by burning it, heating water. When water heats up to steam, it has more pressure. This pressure is used to turn generators. The electricity produced will be direct current. The power plant will have a converter to change the DC into AC, Alternating Current.
What gives off more energy Anthracite coal or bituminous coal?
Anthracite coal, it insulates the heat energy better and has more light energy when lit.
Is solar energy widely accepted?
Not as Much as Wind, Because Solar Panels Cost More Than Wind Turbines , If the Two Create The Same Amount Of Energy The Solar Would Have Costed More to produce the Panels.
What has science done to help wind turbines to develop?
Make wind turbines that create more energy
