NOAA says a national electric grid would make renewable energy optimal

IEEE Spectrum : Most of the power requirements of the US could be met with renewable energy sources, such as wind and solar, as early as 2030, according to a new report from the National Oceanic and Atmospheric Administration. Because of the variability of renewable energy, it has long been assumed either that other energy sources, such as fossil fuels, would be needed to supplement it or that large batteries would be required to store the surplus energy. However, through the use of more precise and higher-resolution weather data, researchers at NOAA say that renewables are the best option to reduce both cost and carbon emissions. The key, however, will be the implementation of a national electricity grid, with high-voltage direct-current transmission lines that span the entire country.
