Which is greener: Solar Power or Wind Turbines for Renewable Energy?

post #1 of 3
Thread Starter 

Hi Green People, recently me and my friends at the Wind Turbines Social Network have a discussion about Solar Power or Wind Turbines for Renewable Energy. Here are some facts about wind and solar energy...

 

 

Quote:

Solar Energy – Solar energy from the sun can easily be converted into sunlight and is now now-well understood process.  The beams of light from the sun hit a photovoltaic (PV) module which responds by generating a current.  This electrical energy is then carried into our homes by wires and circuit breakers.

 

Wind Energy – Although completely different from solar, there are some similarities.  The wind blows the propeller which is on a shaft surrounded by a magnet wrapped by a coil of wire.  Either the magnet turns near the wire or the wire turns causing electrons in the wire to experience force.  The force causes the electrons to move along the wire causing what we call an electrical current.

 

It may seem that environmentalist make solar power, wind power and other alternatives over exaggerate, they are actually very good forms of energy production that many people can make use of.  Although it obviously uses up energy to make the components, they are still cause very little pollution. The methods are simple.  Sun and wind cost nothing. There are problems however; it does cost money to convert the energy into a usable form, plus there are some physical limitations along with engineering difficulties.

 

 

After our discussion we had a debate about which is greener. So guys, what do you think??? Which is greener? Solar Power or Wind Turbines for Renewable Energy?

Wind creates less CO2 per amount of energy produced over its lifetime than solar photovoltaic.  See here.

Agree, wind is the more carbon neutral approach.
