   A heat pump uses about 4,700 watts of power, translating to a cost of about $13.54 to run it all day or nearly $420 if you have it on nonstop for a full month in the winter.

4. Heat pump - Wikipedia

   en.wikipedia.org/wiki/Heat_pump

   Specifically, the heat pump transfers thermal energy using a heat pump and refrigeration cycle, cooling the cool space and warming the warm space. [1] In winter a heat pump can move heat from the cool outdoors to warm a house; the pump may also be designed to move heat from the house to the warmer outdoors in summer.

5. Air conditioning - Wikipedia

   en.wikipedia.org/wiki/Air_conditioning

   The efficiency of air conditioners is often rated by the seasonal energy efficiency ratio (SEER), which is defined by the Air Conditioning, Heating and Refrigeration Institute in its 2008 standard AHRI 210/240, Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment. [61]

6. Cost of electricity by source - Wikipedia

   en.wikipedia.org/wiki/Cost_of_electricity_by_source

   The LCOE below is calculated based on a 30-year recovery period using a real after tax weighted average cost of capital (WACC) of 6.1%. For carbon intensive technologies 3 percentage points are added to the WACC. (This is approximately equivalent to a fee of $15 per metric ton of carbon dioxide CO 2.) Federal tax credits and various state and ...

7. Solar air conditioning - Wikipedia

   en.wikipedia.org/wiki/Solar_air_conditioning

   A solar chimney or photovoltaic-powered fan can be used to exhaust undesired heat and draw in cooler, dehumidified air that has passed by ambient Earth temperature surfaces. Control of humidity and condensation are important design issues. A geothermal heat pump uses ambient earth temperature to improve SEER for heat and cooling. A deep well ...
