Statewide Natural Gas Savings
Residential energy
end use estimates by the CEC show total gas consumption of 4810 million
therms and that 45% of this total is for space heating. The gas used
to heat residences is therefore 4810 million therms x 45% = 2160 million
therms. Assuming about half a million homes heat with electricity then
the remaining 7.5 million homes heat with gas.
Retrofitting the 3 million homes with central air conditioning to achieve
a 10% energy saving, would result in a saving of 0.1 x 3/7.5 x 2160 million
therms = 90 million therms. At $2 a therm this translates to about
$180 million savings a year.
