International Energy Agency says thatsolar
could provide more than 16% of total energy use for heating and 17% for cooling. It would eliminate 800 megatons of carbon
dioxide emissions a year; it would also save money since heating and cooling
account for about 56% of the energy use in an average U.S. home.
Meeting that goal would include using solar
collectors for hot water and space heating, low-temperature process heat in
industry and heating for swimming pools, IEA Executive DirectorMaria
van der Hoevensaid. It would also require a “rapid expansion of
solar hot water heating in the building sector, including in solar-supported district
heating, as well as in industrial applications.”
Solar heating and cooling could increase by 2050
