For the United States to decarbonize its building sector by 2050 and avoid the worst impacts of climate change, we need to simultaneously complete a clean energy transition and make our buildings more efficient. Switching our grid to renewable energy is a huge lift, and we can significantly speed up the process–while keeping energy more affordable– if we simply use less energy, at the right times of day. Smarter, more efficient energy uses will mean fewer new power centers and power lines need to be built. That’s a huge cost savings and we achieve decarbonization faster. To explore this connection in more detail, IMT produced a four-part blog series outlining the connections.
