2. Cost of electricity by source - Wikipedia

   en.wikipedia.org/wiki/Cost_of_electricity_by_source

   The levelized cost of electricity (LCOE) is a metric that attempts to compare the costs of different methods of electricity generation consistently. Though LCOE is often presented as the minimum constant price at which electricity must be sold to break even over the lifetime of the project, such a cost analysis requires assumptions about the value of various non-financial costs (environmental ...

3. Energy factor - Wikipedia

   en.wikipedia.org/wiki/Energy_factor

   The energy factor metric only applies to residential water heaters, which are currently defined by fuel, type, and input capacity. [5] Generally, the EF number represents the thermal efficiency of the water heater as a percentage, since it is an average of the ratio of the theoretical heat required to raise the temperature of water drawn to the amount of energy actually consumed by the water ...

4. Levelized cost of electricity - Wikipedia

   en.wikipedia.org/wiki/Levelized_cost_of_electricity

   The cost of a electricity production depends on costs during the expected lifetime of the generator and the amount of electricity the generator is expected to produce over its lifetime. The levelized cost of electricity (LCOE) is the average cost in currency per energy unit, for example, EUR per kilowatt-hour or AUD per megawatt-hour. [3]

5. Electricity pricing - Wikipedia

   en.wikipedia.org/wiki/Electricity_pricing

   According to the U.S. Energy Information Administration (EIA), "Electricity prices generally reflect the cost to build, finance, maintain, and operate power plants and the electricity grid." Where pricing forecasting is the method by which a generator, a utility company, or a large industrial consumer can predict the wholesale prices of ...

6. Landfill gas utilization - Wikipedia

   en.wikipedia.org/wiki/Landfill_Gas_Utilization

   A 40-acre (160,000 m 2) landfill gas collection system with a flare designed for a 600 ft 3 /min extraction rate is estimated to cost $991,000 (approximately $24,000 per acre) with annual operation and maintenance costs of $166,000 per year at $2,250 per well, $4,500 per flare and $44,500 per year to operate the blower (2008). LMOP provides a ...

7. Gasoline gallon equivalent - Wikipedia

   en.wikipedia.org/wiki/Gasoline_gallon_equivalent

   One GGE of natural gas is 126.67 cubic feet (3.587 m 3) at standard conditions. This volume of natural gas has the same energy content as one US gallon of gasoline (based on lower heating values: 900 BTU/cu ft (9.3 kWh/m 3) of natural gas and 114,000 BTU/US gal (8.8 kWh/L) for gasoline). [22]

8. Thermal power station - Wikipedia

   en.wikipedia.org/wiki/Thermal_power_station

   A typical flue-gas stack may be 150–180 metres (490–590 ft) tall to disperse the remaining flue gas components in the atmosphere. The tallest flue-gas stack in the world is 419.7 metres (1,377 ft) tall at the Ekibastuz GRES-2 Power Station in Kazakhstan.

9. Energy conversion efficiency - Wikipedia

   en.wikipedia.org/wiki/Energy_conversion_efficiency

   An ideal electrolysis unit operating at a temperature of 25 °C having liquid water as the input and gaseous hydrogen and gaseous oxygen as products would require a theoretical minimum input of electrical energy of 237.129 kJ (0.06587 kWh) per gram mol (18.0154 gram) of water consumed and would require 48.701 kJ (0.01353 kWh) per gram mol of ...
