Sunlight is Earth's primary source of energy.
The solar constant is the amount of power that the Sun deposits per unit area that is directly exposed to sunlight.
The solar constant is ~1,370 watts per square meter or ~1273 watts per 10 square feet.
All Renewable energy is directly
connected with our sun, can be called
Solar energy
Energy generated from what we call
natural resources:
A) Sunlight
B) Wind
C) Rain
D) Tides
E) Geothermal heat
F) Biomass
G) Bio-fuel
What is the good thing about RENEWABLE energy sources?
They are naturally replenished by the sun:
Hydroelectricity
Solar hot water/heating
Geothermal energy
Wind power
Solar power photovoltaic
Ocean energy
All renewable energy does not produce
air and water pollution
All renewable energy can be harvested
without burning fossil fuels.
Another good thing:
With about 119,000 jobs, the American
solar industry now employs much more
workers than the U.S. steel production sector
