A new study suggests flexibility in the timing of electricity consumption could lower consumer costs.
From insurance premiums to energy bills, a new study from MIT Sloan shows how Americans are already paying the price of climate change, and climate inaction, driven by extreme weather.
Research by associate dean Christopher Knittel, senior postdoctoral associate Juan Ramon Senga, and postdoctoral associate Chaitanya Vuppanapalli has identified technologies that could save the United States as much as $1.34 billion annually in electricity system costs by making better use of existing transmission lines. The study examined how improvements to existing transmission infrastructure could increase electricity delivery without relying entirely on expensive and time-consuming construction of new lines.
Associate dean Christopher Knittel joined this podcast to discuss the costs and benefits of clean energy. "We should continue to subsidize rooftop solar, but we should do it in a way that's not regressive, that is not leaning harder on those homes that cannot install solar," Knittel said.
In a research brief, associate dean Christopher Knittel and co-author wrote: "Using a two-way fixed-effects regression model that controls for unobserved differences between years and between states, we found that renewable energy portfolio standards have virtually no impact on prices, and large-scale renewables are moderately associated with lower prices; in particular, large-scale solar is strongly linked to lower prices."
Associate dean Christopher Knittel and co-author wrote: "A simple accounting check shows why our estimated magnitude isn't a stretch. In Massachusetts, fixed costs make up roughly 60 percent of total system costs, and about 13 percent of customers have rooftop solar and pay very little, if anything, toward those costs because net metering zeroes out their bills. When this happens, the fixed cost of running the grid doesn't shrink; it just gets divided over a base that's 13 percent smaller."
