wind as an alternitive energy source
Where does it come from? Is it renewable?
Wind comes from the movement of the air. Wind is always moving. Warm air rises and cool air takes its place. It is renewable, too. As long as the earth keeps on heating and cooling, there will be wind power.
Is it Costly?
For a 10 kW wind turbine costs about 50,500 to install and about 40,000 for the equipment. It will however recover the cost from 6 years to 30 years depending on the wind speed and cost of electricity. It is however enviourmently friendly, so it could be a good spend depending on if you can pay for it and where you live.
Impact on the earth (advanteges and disadvanteges)
Wind power is a clean source or energy and has fewer enviornmental impacts than other energy sources. It does not polute the air or water. Plus they don't require water for cooling. The only real problem they have is that they take up space and some have caught on fire. Overall, it is better to have wind turbines than none at all.
