The amendment would require gas stations located within a half-mile of a highway exit or hurricane evacuation route to be prewired for backup generators, which would allow electricpumps to continue to pump fuel in the case of a power outage.
Among the energy-saving options, two promising technology switches are the electrification of transportation (electric vehicles can be about four times as energy-efficient as standard fossil-fuel vehicles) and the use of electric-powered heat pumps to deliver winter heating and hot water (heat pumps can be four times as energy-efficient as standard heaters).
