The US Department of Energy released last week an interesting study on how LED lightning could enable America to save $120 billion (88 billion euros) over the next 20 years. To Ecogeek :
” The cumulative savings of widespread adoption of this technology over the next 20 years would be about 1.500 terawatt-hours (…) The savings would eliminate the need for 24 new large power plants.”
What occurs in lightning should concern all economic sectors : transportation, housing, appliances, industy… Energy conservation and efficiency are the best solutions to climate change and energy scarcity.
