At the community or village level, the use of crop residues to power small steam turbine generators to produce electricity can deliver environmental and social benefits in addition to saving carbon. (nativeenergy.com)
But going from heat to electrical or mechanical energy involves considerable losses; typical steam turbine generators run at about 33 % conversion efficiency — i.e. only 1/3 of the thermal energy gets converted to electricity. (sciscoop.com)
By tracking the sun on two - axes and concentrating its energy in a single place at the boiler, the system is able to produce steam at temperatures that take advantage of the world's most efficient steam turbine generators. (brightsourceenergy.com)
