Solar energy workshops for home owners US/UK/Australia?
I am new to alternative energy. I have relatives in these countries i live in Colorado and others in California/Michigan/Texas or any other states.
We all saw an Inconvenient truth documentary and thought that we should start going green at our homes.
Can anyone tell me about–
- workshops for solar energy
- where to get cheap solar panels or photovoltaic cells
- President Obama’s policy on alternative energy
- Wind energy Vs Solar Energy
Also how much solar energy would be required for one family home?
(or link to solar energy calculator)
Also do you know about anyone who is using solar energy and how is it going?
thanks!
