Mitigation

Reducing Urban Heat Islands, a compendium of strategies from the EPA:

Using the Los Angeles basin as a model, Lawrence Berkley National Laboratory made some projections based on the conversion of 15% of dark surfaces to cool surfaces. In this model, summer temperatures dropped 6°F

This matters for both smog and energy use reduction. In Los Angeles “...peak power rises 3% for every 0.5°F rise in daily maximum temperature...about 1-1.5 gigawatts of power are used to compensate the impact of the heat island... costing the Los Angeles ratepayers about $100,000 per hour, about $100 million per year”
