Why Solar is a Good Idea for Residential Use

As posted yesterday, I’m reading a new book.

Physics for Future Presidents: The Science Behind the Headlinesby Richard A. Muller is a review of the current international energy issues for people with average math and science abilities. He does a good job of speaking science in the language of everyday people.

He lists some interesting facts about solar energy which may grab your imagination.

Overhead sunlight delivers to the ground approximately
•    100 watts per square foot
•    1 kilowatt per square yard
•    1 horsepower per square yard
•    1 gigawatt per square kilometer
•    3 gigawatts per square mile

What this means is that solar power is a promising energy source for a home, but not a car.

Take a look at the book and be amazed. You really can understand science!
