Emissions Reductions

SWG is reducing carbon emissions now

Our technology makes it possible to retire coal now and affordably replace it quickly and reliably with a combination of gas and renewables – which in turn leads to rapid grid decarbonization. The combination of gas and renewables has driven a 26% reduction in U.S. carbon emissions from the power sector in the last 10 years. In absolute terms, this means the U.S. power sector reduced annual CO2 emissions by 610 million tons between 2008 and 2018.

"Our paper calls attention to the fact that renewables and fast-reacting fossil technologies appear as highly complementary and that they should be jointly installed to meet the goals of cutting emissions and ensuring a stable supply"

We’re at a time of deeply ambitious plans for clean energy growth. Two of the U.S.’s largest states by population, California and New York, have both mandated that power companies get fully 50 percent of their electricity from renewable sources by the year 2030.

Only, there’s a problem: Because of the particular nature of clean energy sources like solar and wind, you can’t simply add them to the grid in large volumes and think that’s the end of the story. Rather, because these sources of electricity generation are "intermittent" — solar fluctuates with weather and the daily cycle, wind fluctuates with the wind — there has to be some means of continuing to provide electricity even when they go dark. And the more renewables you have, the bigger this problem can be.

Now, a new study suggests that at least so far, solving that problem has ironically involved more fossil fuels — and more particularly, installing a large number of fast-ramping natural gas plants, which can fill in quickly whenever renewable generation slips.
