Answer 1

Answer:

Climate change will reduce energy demand for heating and increase energy demand for cooling in the residential and commercial

sectors (robust evidence, high agreement); the balance of the two depends on the geographic, socioeconomic, and technological conditions.

Increasing income will allow people to regulate indoor temperatures to a comfort level that leads to fast growing energy demand for air

conditioning even in the absence of climate change in warm regions with low income levels at present. Energy demand will be influenced by

changes in demographics (upward by increasing population and decreasing average household size), lifestyles (upward by larger floor area of

dwellings), the design and heat insulation properties of the housing stock, the energy efficiency of heating/cooling devices, and the abundance

and energy efficiency of other electric household appliances. The relative importance of these drivers varies across regions and will change over

time. {10.2}
