☆ wind - a renewable & clean source of energy
☆ a 10 kW costs about $50,000 to $65,000, along with the cost of shipping, and installation
☆ modern turbines can be as a tall as a 20-story building
☆ the turbine wings are shaped like airplane wings & is long as a football field
☆ one wind turbine can power up to 500 houses
☆ wind mills can be as tall as up to 200 meters, with wings that can move up to 200 mph.
☆ a wind turbine converts kinetic energy from wind into 'rotary mechanical energy' which is used for doing work
☆ no harmful polluting gases are produced
☆ wind farms work best in open areas of slightly rolling land surrounded by mountains because these areas are preferred because the wind turbines can be placed on ridges and remain unobstructed by trees and buildings, and the mountains concentrate the air flow, creating a natural wind tunnel of stronger, faster winds
☆ wherever a wind farm is to be built, the roads are cut to make way for transporting parts

HOW IT WORKS
But first, wind is air in motion created by uneven heating of the earth by the sun.
Wind energy in the wind turbines turns two/three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity.
BENEFITS
clean source of energy
renewable energy
modern tech
can already be built on existing farms
DRAWBACKS
threat to wildlife
expensive
safety of people
uses up lots of land
