As you probably know, EROI is "simply" the ratio of energy delivered to users over the energy spent in extracting/converting/delivering the energy. Is anyone here using this metric to compare renewable versus non-renewable energy? Do you know any good sources of data on "Energy Return on Energy Invested" (EROEI or EROI)? Good data for the denominator (by industry, sector, etc) seems to be scarce!
