Every 24 hours, wind generates enough kinetic energy to produce roughly 35 times more electricity than humanity uses each day. And unlike coal or oil, this resource is totally renewed each day. So how can we harness this incredible amount of energy...
With the development of our society, energy in the world bees more and morelimited, so it is quite important for us to save energy and to protect ourenvironment. As a student, there are a lot of methods we can do to save energyat home. For example, first, we can turn off the light...
Wind energy is truly a renewable (可再生的) resource. No matter how much wind we use to produce electricity, we will never reduce the supply (供应) of wind. This is its greatest advantage when it is compared with non - renewable resources like coal or oil.What does "resource" mean in...

Offshore wind energy Offshore wind energy is produced in a very similar way to onshore energy by using wind turbines that harness the force of the wind to produce electricity. The only difference is that for offshore energy the wind turbines are installed in the middle of the ocean to take...
How to Generate Electricity with Geothermal Energy Geothermal energy is energy from within the earth. The earth from inside is too hot. This heat from within the earth can be used to turn turbines and produce electricity. This technology is still a subject matter of further research and engineer...
The basic requirement for the electricity generation using wind energy is to produce ac signal of constant frequency irrespective of the wind speed. In other words the frequency of the ac signal generated across the stator should be constant irrespective of the rotor speed variations. To achieve th...
