Electrify every energy flow that is currently powered by fossil fuels, including buildings, transportation, and manufacturing.
Electrifying everything refers to replacing our fossil-fuel economy with wind, solar, hydro, electric vehicles, heat pumps, and a masterfully designed electric grid that allows a two-way transfer of energy. According to physicist Saul Griffith, if we electrify the whole world economy, we will need less than half of the primary energy we currently use. The complete switch from fossil fuels to renewables such as wind and solar will reduce overall energy by 23 percent, for starters. Electrifying transportation will save another 15 percent, eliminating mining and refining of fossil fuels will save another 11 percent, electrifying buildings will save 6–9 percent, and removing fossil fuels in the production of our daily materials will save another 4–5 percent. These figures are granular of course, but they describe how electrification results in emissions efficiency—we can achieve the same amount of work and meet the same needs with far fewer carbon emissions.
