Solar Power Energy – The Moon is a ball of left-over debris from a cosmic collision. That took place more than four billion years ago. A Mars-sized asteroid – one of the countless planetesimals that were frantically churning . Our solar system into existence – hit the infant Earth, bequeathing it a very large natural satellite.
Clearly, we need more incentives to quickly increase the use of wind and solar power; they will cut costs, increase our energy independence and our national security and reduce the consequences of global warming.
Solar Power – How Solar Plants Work
You will find two ways we can produce electricity from the sun:
Photo voltaic Electricity – This method uses pv cells that absorb the direct sunlight just like the solar cells you observe on some calculators.
Solar-Thermal Electricity – This also uses a solar extractor: excellent mirrored surface that reflects the sunlight on to a receiver that warms up a liquid. This kind of heated liquid can be used to make steam that produces electricity.
