The sites, once a source of greenhouse gases, have a useful feature: They're wired to the electricity grid. For new ventures like solar farms, that can save a lot of time and money.
Daily emission estimates are essential for tracking the dynamic changes in emission sources. In this work, we estimate daily emissions of coal-fired power plants in China during 2017–2020 by combining information from the unit-based China coal-fired Power plant Emissions Database (CPED) and real-time measurements from continuous …
Coal stockpiles have surged to nearly 130 million tons in June—enough to run coal plants for 113 days, or nearly four months, based on the average amount of coal used over the previous year. The amount of coal used each day in the U.S. has fallen from about 2.8 million tons a day in 2008 to about 1.1 million tons a day this year—a 62% drop.
