Wind and Solar Power could Meet 85% Electricity Needs of the US

According to a report published in Nature Communications, Wind and Solar power may supply roughly 85% of the US’s electricity needs. Batteries, capacity overbuilding, and other storage choices could all contribute to an increase in that number. According to the report, a combination of Wind and Solar power should be sufficient to cover the majority of current energy needs in “advanced, industrialised nations.”

Researchers from UCI, Tsinghua University in China, the Carnegie Institution for Science, and Caltech examined 39 years of hourly energy demand data from 42 nations to see if there are enough Wind and Solar resources to meet demand.

Wind and Solar Power could Meet 85% Electricity Needs of the USThey discovered that the most reliable systems, in which wind power is most abundant, can supply energy needs between 72 and 91 percent of the time in the countries they analysed, and that’s before any storage considerations. These renewable energy sources can meet between 83 and 94 percent of hourly energy needs when they have the potential to store up to 12 hours’ worth of energy. However, even if Wind and Solar power can provide over 90% of a region’s energy needs, there will still be hundreds of hours each year when demand isn’t fulfilled, according to the researchers.

Geophysical issues are present. Larger countries closer to the equator, according to the report, would find it easier to fully transition to sustainable energy sources because they can count on solar energy throughout the year. Because it is a smaller country at a higher latitude, Germany, for example, may struggle to supply the majority of its demands with Wind and Solar. For example, adjacent countries could pool their resources. Many countries are reducing their reliance on fossil fuels, which is critical for reducing carbon emissions and lessening climate change’s impact.
