To upgrade energy efficiency, retrofit old buildings—with plants. A living wall composed of pockets of greenery installed on the outside of a building can shrink the amount of heat lost through an un-insulated wall by nearly one-third, according to a new study. The findings suggest a new strategy for making older buildings more energy efficient.

The difference in conversion rates is because coal-fired generation plants in the United States are often older and less efficient than many natural gas-fired plants. In U.S. power plants, generating a kilowatthour of electricity from coal requires on average about one-third more energy than producing a kilowatthour from natural gas.
