Energy is sustainable if it meets the needs of the present without compromising the ability of future generations to meet their needs. Sustainability issues in the current energy system include high emissions of greenhouse gases, air pollution from the burning of fossil fuels and biomass, and pervasive energy poverty in developing countries. The scientific literature on limiting global warming describes pathways in which the world rapidly phases out coal-fired power plants, produces more electricity from clean sources such as wind and solar, shifts towards using electricity instead of fuels in sectors such as transport and heating buildings, and takes measures to conserve energy. These changes would involve a system-wide transformation of the way energy is produced, stored, distributed, and consumed. Decarbonization of the energy system would bring major co-benefits to human health and can be done in concert with providing universal access to electricity and to clean cooking.

___________________________ Wikiquote quote of the day:

A lot of writers write as if the hero sort of popped out of the box at age 22 fully formed. And one thing that raising children does is give you some sense of how human beings really are put together. So when you go to put together a character you can have a more realistic sense of where people really come from, why they really behave the way they do and what a tremendous amount of life and complexity lies behind every human being.   --Lois McMaster Bujold https://en.wikiquote.org/wiki/Lois_McMaster_Bujold
