That must asssume some sort of > gas-to-electricity converter machine. The US uses the antiquated British Thermal Units (BTU) for gas billing. A single BTU is equivalent to 1054J or about 0.293 Wh. They are normally billed in groups of 100,000 BTUs called a Therm equivalent to 29.3kWh. Current rates for gas in the SF Bay area are about $2/Therm. This is equivalent to ~7c/kWh, electricity is 40-60c/kWh depending upon time of day etc. Even accounting for 10-30% loss in gas appliances gas is cheaper than using a heat pump with a COP of ~3-4 for space and water heating. kw > The easy way would be to compare direct gas heating with resistive > electric heating, both of which are crazy inefficient. > > There is a movement here to eliminate gas to Save The Earth.
