Solar
•Every
15 minutes the sun produces enough power to supply the earth for an
entire year, but most of the sun energy that reaches the earth is used
for living things and to keep the cycle of “water evaporation and
precipitation” going.
•
•Solar energy costs nothing when it hits the earth, but in most cases it costs money to change it into useable energy.
•
•
It can become one of the most valuable energy resources for the future,
especially because there are limits to how much oil, gas, and coal
people can use.
