wormit claims to be the first scottish village to have installed electricity. a windmill located on wormit hill generated the power, with a steam engine supplementing this when the wind was low. this was later replaced by a coal-gas engine until the 1930s, when wormit was connected to the national grid. alexander stewart, who built many of wormit's early houses, owned the windmill and steam engine and offered electrical lighting to homeowners as well as basic street lighting. consumers paid 10 shillings a quarter and could use as much electricity as they liked. the first houses to have electricity had sun rays painted on the front, and these can still be seen along the highest row of terraced housing in the village.

denmark often produces more electricity from windpower than the entire country requires and will export it for sale or for storage in hydroelectric dams in norway and sweden. occasionally electricity prices turn negative for producers when there is a glut of electricity production and lack of demand abroad as well. one result of this has been the growth of electric boilers being installed in district heating plants. when there is an excess of electricity the plants can use cheap electricity to heat the hot water instead of finite bio or fossil fuels. as wind production rises the problem of too much electricity being generated will also give rise to new challenges and solutions. electric heating and cooling can also be used in the form of more efficient heat pumps to mop up excess electricity supply. the electricity sector will in effect expand into the heating and cooling sector to displace current energy sources.
