7.8 million more homes heated by electricity in 2014, compared to 2005. Just 0.8 million more heated by gas. Census

Homes heated by electricity now up to 37.4%. By gas now down to 48.5%. By oil now down to 5.3%. Census, 2014

States with the highest % of electric heated homes: Florida, Alabama, Louisiana, North Carolina, Tennessee

States with lowest % of electric heated homes: Vermont, Maine, New Hampshire, Michigan, Rhode Island. Census, 2014

Since nearly 60% of new homes are in the south & barely 5% in the northeast, the share of electric versus gas or oil heated homes will grow

In first months after Pearl Harbor, how did FDR reconcile rationing electricity with desire to keep the bright lights on for night baseball?

Utility-scale solar photo-voltaic producing 4 times as much power as all home rooftops this yr thru Sept. Energy Dept. data. #solarenergy

How much power produced by all the home solar rooftops in the US? As much as one 750 MW natural gas power plant run at 93.5% of its capacity

Half of all power produced by home solar rooftops is from California rooftops. Just 2,320,000 MWH from rooftops in other 49 states thru Sept

#solar on home rooftops = 0.1% of US electricity supply. Utility-scale #solarenergy = 0.6% of US electricity supply. 2015 thru September

#solar on home rooftops= 16% of US #solarenergy. Utility-scale solar= 76% of all energy produced by solar, near 5 times more. 2015 thru Sept

#solar on home rooftops =17% of US #solarenergy. Utility-scale solar = 66% of all energy produced by solar, near 4 times more. Correction

But 76% of increase in US #solarenergy this year versus last yr came from solar farms operated by or for utilities. Just 16% from home roofs
