There are two kinds of micropower. One is co-gen and combined heat and power. That was about two-thirds of the new capacity and three-quarters of the new electricity last year. The rest was distributed or decentralized renewables, which was a $38 billion U. S. global market last year for selling equipment. That's wind, solar, geothermal, small hydro and biomass.... Micropower surpassed nuclear power in worldwide installed capacity in 2002, and surpassed nuclear in electricity generated per year just in the last few months.
