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.
