SUNLIGHT AND WIND ARE INEXHAUSTIBLE RESOURCES. EXPLAIN WHY THEY ARENT USED TO PRODUCED ALL OF OUR ENGERY
I'm sure your teacher wants your ideas and not mine; however, here are a couple of items to chew on to get you started.
1. Cloudy days limit the sun. Wind doesn't blow all the time.
2. Units that convert solar energy to electrical energy are not very efficient although they are MUCH better today than say 20 years a go.
3. What about the landscape? How much space to they occupy? Would you like a solar panel array (or arrays) in your front (or back) yard? Would you buy a house on a hill with a beautiful landscape that could become a wind turbine farm in the valley below. So long beautiful view.
