Wind energy is very efficient (makes money) when the wind is blowing but when it stops, it's all overhead.
This means it cost too much.
Wind energy costs 5million a year
£10,234 to be exact.
It Costs $5.00
So far it is free because wind is a renewable energy source but you have to count the turbine and generator and everything that produces the electricity.
This is a question of how much electrical energy you want to produce, against the cost of the equipment to produce it.
5 cents per kilowatt hour
wind energy is free
It has not progressed much in terms of cost effectiveness. It still uses more energy to fabricate, put together and maintain a wind turbine than it will produce in ten years.
Around 2% of energy consumption is wind energy.
Around 2% of energy consumption is wind energy.
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.
Actually, most of our energy comes from wind energy sources, like wind turbines. Wind turbines are used all around the world.
