hello croolk,

i have been looking into solar and wind power for over a year now. i agree that there a payoff with free energy.

the biggest problem is the initial investment and the time it takes for a real return.
3-5 years is unreal and from what i see more like 10-15 years if you are lucky. work and maintenence is also an issue. from people ive talked to these machines don't last much more than twenty, so untill they build better turbines and panels. it's just not that tempting.
