Collection Cost

Cost for power from methane gas from sewage is about $6.5/kilowatt - not too bad the best I can tell only about 10-30 times more expensive than conventional gas or diesel generators. Unfortunately I doubt it will come down enough in the next 4 years so as to be practical for us common users. How does this compare to wind and water power prices?

Offered by Mike.

Like many things it is based on the economy of scale. Bigger = cheaper per watt, but figure $1.30 per watt for just the wind generator only, ($5 for solar), $1.10-$1.30 per watt for hydro electric pelton type generators.
