This April, for the first time in U.S. history, the renewable energy sector is expected to have generated more total electricity than coal. According to an initial report by the Institute for Energy Economics and Financial Analysis, this achievement is partially because of increased investment and awareness, but might also be due to seasonal changes in electricity consumption.
“Five years ago, this never would have been close to happening,” Dennis Wamstead, research analyst at IEEFA, said in the report. “The transition that’s going on in the electric sector in the United States has been phenomenal.”
Americans demand more renewable energy
According to the IEEFA report, there has been increased investment in the wind and solar field, making the technology less expensive and more widely accessible. Increased awareness about climate change and the role of carbon emissions has also led local governments, businesses and residents to demand renewable energy policies and services.
Renewable energy sources include hydro, geothermal, solar, wind and biomass energy, although solar and wind are the two sectors that have seen the most rapid upsurge.
Coal still reigns in the summertime
Although this record-breaking achievement is exciting, energy experts also said that it could be partially explained by seasonal electricity demands. Many companies temporarily shut down coal plants for seasonal maintenance in the springtime, when electricity demands are lowest. There is also an abundance of wind and hydro energy during that time. However, once people start turning on their air conditioners around June, electricity production is expected to be dominated by coal and natural gas again.
Despite the current federal government’s attempts to boost the coal industry, coal consumption has been steadily declining. In 2016, natural gas surpassed coal as America’s biggest source of electricity, with coal contributing 27 percent of electricity and natural gas contributing 35 percent. Although it is cleaner than coal, natural gas is still a fossil fuel and therefore contributes to climate change.
The report also predicts that renewable energy will outshine coal in May, and going forward will sporadically compete with coal on a monthly basis. However, coal and natural gas are expected to dominate annual consumption patterns for several more years.
