What is Wind energy?
Wind turbines use blades to collect the wind's kinetic energy. Wind flows over blades creating lift (similar to the effect on airplane wings), Which causes the blades to turn. The blades are connected to a drive shaft that turns an electric generator, which produces (generates) electricity.
How does wind power help the enviroment?
WInd turbines do not release emissions that can pollute the air or water (with rare exceptions), and they do not require water for cooling. Wind turbines may also reduce electricity generation from fossil fuels, which results in lower total air pollution and carbon dioxide emissions.
in dollars it costs $1,300,000 in USD per megawatt!egawatt!
nonrenewable energy
There are four major types of nonrenewable resources: oil, natural gas, coal and nuclear energy.Oil is a nonrenewable enrgy because once it is used it cant be replaced which is a major problem for humanity as we are currently dependant on them to supply most of our energy needs.
