About Kilowatt Hour (kWh)
The global standard unit of electrical energy billing — equal to a kilowatt of power consumed (or delivered) for one hour, or 3,600,000 joules. Residential electricity bills, utility-scale grid planning, electric-vehicle battery capacities (e.g., Tesla Model 3 = 75 kWh), and home solar production are all quoted in kWh. Typical US household electricity consumption is about 900 kWh per month; EV efficiency is roughly 0.25 kWh per mile.
About British Thermal Unit (BTU)
An imperial unit of heat energy, defined as the amount of heat required to raise one pound of water by 1°F (about 1,055 joules). BTUs are the dominant unit in US HVAC and heating/cooling: air conditioner capacity (a 12,000 BTU/h unit is a "1-ton AC"), gas furnace output, and natural gas heating content. "MMBTU" (million BTU) is the US energy wholesale unit for natural gas and industrial fuel contracts.
