The Answer Is Blowin' in the Wind

The Answer Is Blowin' in the Wind

We might not have cute old-fashioned windmills anymore, but today's wind turbines make a LOT more electricity. Their propeller blades can be 200 feet long and slice through the air at 180 miles an hour! The blades turn the machine inside to make electricity, which then flows through the wires to our houses. One light bulb uses around 60 watts; these wind turbines make 1 million watts, enough to power many towns. Let's hope the wind keeps blowing!
