Energy Concerns:

Residential heating and cooling account for about 56% of the energy use in a typical U.S. home, making it the largest energy expense for most homes, according to the U.S. Department of Energy. More than 5% of electricity demand in many countries is spent on residential cooling alone. Many electricity blackouts are directly linked to peak demand hot weather days (France 2003, Australia 2008 and more). Shifting to solar energy for cooling saves electricity without compromising on comfort.

Environmental Concerns:

Global warming is expected to raise summer temperatures in Europe and parts of the USA by 2-4°C by the end of the century. Already, Spain, Italy, Greece and parts of France have turned from having a winter electricity peak to a summer peak, due to increase in A/C systems installed and used.

Shifting to solar energy for cooling reduces emissions without compromising on comfort.

Solar cooling and heating can reduce peak energy demand and increase the use of renewable energy, while providing energy savings.
