In 2012, for the first time, China increased its wind power production more than its coal power production!

  • Coal power production rose by 0.3%, an addition of roughly 12 terawatt hours (TWh) more electricity.
  • Wind power rose by about 26 TWh. This increases China's wind energy to 100TWh, putting it in third place after coal and hydro, and larger than nuclear in fourth place.

What is wind energy?

A large mass of air moving over the landscape represents aconsiderable amount of energy. By building devices that will spinwhen the wind blows, it is possible to harness some of that energy.Most modern wind turbines are several hundred feet high, withpropellers that have 3 blades, each one about 150 ( Full Answer )

What is coal energy?

Coal energy is energy derived from the burning of coal. Coal is essentially fossilized carbon.

How does wind energy produce energy?

Most commonly through windmills. the wind pushes on a tilted blade causing it to rotate. A generator inside the windmill then truns the kinetic energy of the rotation into an electric current. u blow on it

Does coal give off the most energy?

Propane produces 21500 BTU per pound, Gasoline 17500 BTU per pound, Coal between 12,000 BTU per pound (Anthracite) to 10,000 BTU per pound (Bituminous) and wood (dried) 7000 BTU or so. On the other hand, Coal can be converte ( Full Answer )

What are the similarities between coal and wind energy?

None, however there are many dissimilarities. Coal is a fossil fuel. Burning it consumes a limited resource and generates CO2 which contributes to global warming. Wind generation, like solar power and hydro-electric generation do not involve consumption of minerals. Also, they are non-polluting form ( Full Answer )

How do you get energy from wind?

Wind energy is associated with the movement of atmospheric air which is converted into kinetic energy. This energy has been used for sailing, irrigation, and more recently for power generation.

Availability of solar energy tidal energy coal energy and wind energy?

Coal is portable, so once it is dug up and processed we can send it almost anywhere. The others are rather geographically dependant. Solar energy is fairly well available to most populations, because we tend to live in fairly temperate areas (though the people who live close to the poles don't have ( Full Answer )

Is coal an energy?

Not really.. Energy is released when coal is burned. It is not coal itself, but the reaction of oxygen and coal once ignited that results in energy.

What can you do to increase your energy?

Getting a basic 8 hours of sleep is beneficial, and an extra hour or so should be sought after if you ar ( Full Answer )

Wind energy is what form of energy?

Wind is an example of motion (kinetic energy). Using this kinetic energy it is possible to generate electricity. The kinetic energy of moving air initiates the force that turns a windmill's blades. It spins a drive shaft that in turn spins the shaft of a generator to make electricity. A gear box ( Full Answer )

Can wind energy be converted into energy?

Yes, kinetic energy can be converted into almost any other form of energy (if you can find the technology to do so) for example. into electric energy by using a spinning generator to produce electricity.

Why is the wind energy the best energy?

one reason is it will never run out sadly it does not always blow but they put wind turbines in windy spots (fields, plains, etc.) places where the wind will not be blocked by something.

How does the wind get energy?

Basically from the Sun. The Sun powers our weather systems, which is what makes the windsthat spins the turbines blow

How does wind energy give energy?

Power generated from the wind. The power of the wind cause windmills to turn, and that turning is used to turn generators, and the generators give off electrical energy that we can use.

What type of energy is wind energy?

Renewable energy. Wind energy is made by the wind it is really very simple all it is is the wind blowing wind then that electricity is drawn into a large generator which is then formed into wind energy that can power your home appliences.

What kind of energy of water increases as the water is heated by the coal?

As water is heated in a coal-fired boiler, the enthalpy of the water increases. Note that enthalpy is defined as: . H = U + pV . where. H is the enthalpy of the system U is the internal energy of the system p is the pressure at the boundary of the system and its environment V is th ( Full Answer )

Why is wind energy the energy of the future?

It will probably not be "the" energy of the future, but it is quite useful because of its inifnite renewability, minimimal harm to the environment, and reliability for energy. However it lacks in how much power it can produce and how consistent it produces it, which is where its downfall is.

What are social advantages of coal energy?

Communities all come together when a coal mine disaster occurs. Some coal barons donate magnanimously to their favorite charities, especially to congressmen unimpressed by the science of anthropogenic global climate change.

How is wind energy used for energy?

Wind energy relies on a propeller like instrument that is moved by the wind. When the blades of it are turning it is connected either directly, or through a set of gears to a generator of some kind. So that when the wind is blowing through the propeller causing it to spin it turns the generator whic ( Full Answer )

Is coal a better source of energy than wind turbines?

Yes In terms of energy yield and availability, it most certainly is. A large coal power plant can produce what a wind farm does in a much smaller space with fewer metal and labor resources used. Also, coal deposits in the earth are HUGE. They are so large in fact that they are expected to last over ( Full Answer )

Why is wind energy clean energy?

Because you're not exactly damaging the "Earth" (example: Global Warming, Green House Gases) you're using the natural air to make electricity. :)
