It’s Now Time to Electrify Everything
For too long, the climate solutions conversation has been dominated by the supply-side view of the energy system: What will replace coal plants? Will natural gas be a bridge fuel? Can hydrogen power industry? These are all important questions, but, crucially, they miss half the equation. We must bring the demand side of our energy system to the heart of our climate debate.
The demand side is where humans, households, and voters live. It is where we use machines on a daily basis, and where the choices about what kind of machines we use—whether powered by fossil fuels or electricity—make our climate actions and climate solutions personal. We don’t have a lot of choice on the supply side, but we have all of the choice on the demand side. For the most part, we decide what we drive, how we heat our water, what heats our homes, what cooks our food, what dries our laundry, and even what cuts our grass. This constitutes our “personal infrastructure,” and it is swapping out that infrastructure that will be a key driver of the global transition from fossil fuels to green energy.
According to an analysis by Rewiring America, a nonprofit think tank I co-founded that focuses on electrifying our lives, if we redraw our emissions map around the activities of our households, we see that about 42% stem from the decisions we make around our kitchen tables. It gets close to 65% if we include the offices, buildings, and vehicles that are connected to the commercial sector and the decisions we make from our office desks.
The supply-side climate challenge is a question of a relatively small number of giant machines, including coal mines, LNG terminals, pipelines, refineries, and natural gas- and coal-fired power plants, all of which are owned by corporations. The demand-side climate challenge involves a very large number of relatively small machines. In the United States, it’s our 280 million cars and trucks, our 70 million fossil-fueled furnaces, 60 million fossil-fueled water heaters, 20 million gas dryers, and 50 million gas stoves, ovens, and cooktops.
The traditional storyline for what we can do in our own lives has been an “efficiency-first” narrative that was born of the 1970s oil crisis. During that time, we needed to adjust to a reduction in foreign oil supplies, which led to more efficient cars with better gas mileage and more efficient appliances. That gave us efficiency as policy, such as federally mandated vehicle fuel standards, and led to Energy Star appliances.
But now we’re facing a completely different kind of energy crisis. To address global warming in time to keep the Earth livable, we need to get to zero emissions as soon as possible. It should be obvious that we can’t “efficiency” our way to zero and that we need to transform our way to no emissions. Starting on the demand side, this leads to a clear conclusion: We must electrify everything. And quickly. And we must supply all those new electric machines on the demand side with cleanly generated electricity on the supply side.
