www.energy.gov• Power to heat is the ratio of electric energy generated divided by the amount of useful thermal energy delivered. A related metric is the thermal to electric ratio expressed in units of Btu/kWh. The power to heat ratio follows a trend similar to electric efficiency, with fuel cells generally having the highest value, followed by
