BACTERIA ARE MAJOR SOLAR POWER GENERATORS. “Cyanobacteria (account) for 20–30% of Earth’s photosynthetic productivity and convert solar energy into biomass-stored chemical energy at the rate of ~450 TW. 25 Gigatons of carbon are sequestered annually from cyanobacteria alone; more than the 8.67 gigatons of carbon released from fossil fuels worldwide in 2008… The total photosynthetic productivity of earth is between ~1500–2250 TW, or 47,300–71,000 exajoules per year.””
