Solar pannels are not environmentaly friendly either, the power to create one, make the glass and silicon wafers and all the other parts and assemble them is higher than the average lifetime power generated by the unit, they are good for remote stations and such but not for real genertion of power
a better method of solar generation is to focus light with mirrors onto a pipe of water and then use the heating of the water to make steam and turn a turbine, but even this is inefficient compared to geothermal, wind, and hydro power.
