28% of the world’s total energy use is wasted but Is potentially recoverable
Can recover 144 GWe of electrical power from this waste heat, worth US$359B (at US$2,500/kWe)
World geothermal potential is 148 GWe
World biomass potential is 25 GWe
World solar thermal potential is 25 GWe
Natural energy + waste heat markets: 342 GWe or US$854B
An Organic Rankine Cycle (ORC) heat-to-power system is best suited for making electricity from these low-grade heat sources, using an organic fluid to match the fluid’s properties with the temperature of the heat source.
