Frequently Asked Questions (FAQs) U.S. Energy
DefinitionsExamplesScopeHeat rate is one measure of the efficiency of a generator or power plant that converts a fuel into heat and into electricity. The heat rate is the amount of energy used by an electrical generator or power plant to generate one kilowatthour (kWh) of electricity. The U.S. Energy Information Administration (EIA) expresses heat rates in British thermal units (Btu) per net kWh generated. Net generation is the amount of electricity a power plant (or generator) supplies to the power transmission line connected to the powe
Natural Gas Is Efficient IGU
2020-7-9 For the oldest power-generating facilities 60% more coal needs to be burned to generate the equivalent power of a natural gas power generation plant. Conversion of energy can exceed 90% efficiency, far greater than any other energy source. Natural gas is the efficient and effective fuel into a low-carbon energy future.

What is an efficiency of modern average car IC engines?
The engine efficiency depends on the engine rpm and load. Car engines rarely operate at their peak efficiency, so peak efficiency and rated power are of limited relevancy to the reality.
