This gets expensive both in terms of the money spent on each individual heater and the electricity it takes to run them — especially in a big house (it also increases the risk of overheating ...
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 ...
A central heating system provides warmth to a number of spaces within a building from one main source of heat. It is a component of heating, ventilation, and air conditioning (short: HVAC) systems, which can both cool and warm interior spaces. A central heating system has a furnace that converts fuel or electricity to heat.

A home fuel cell or a residential fuel cell is an electrochemical cell used for primary or backup power generation. They are similar to the larger industrial stationary fuel cells, but built on a smaller scale for residential use. These fuel cells are usually based on combined heat and power (CHP) or micro combined heat and power (m-CHP ...
For space or water heating, electric heat pumps consume roughly half the energy required by electric resistance heaters. Natural gas heating efficiencies have improved through use of condensing furnaces and boilers, in which the water vapor in the flue gas is cooled to liquid form before it is discharged, allowing the heat of condensation to be ...
A California utility is backing the largest new geothermal power development in the U.S. — 400 megawatts of clean electricity from the Earth’s heat — enough for some 400,000 homes.
When launched in 1994, Home Energy Saver was the first and only online home energy calculator. Thereafter, 6 million people have used it to analyze their home energy use. Nearly 1 million people visit the site each year. In 2009, a second version of the tool, Home Energy Saver Professional, was launched. This advanced version provides a low ...
