If there is one thing almost every clean energy analyst agrees on, it’s that, when it comes to grids, bigger is better. Sharing energy over a wider geographic area improves efficiency, smooths out peaks and troughs in demands, reduces the use of duplicative backup sources, allows for the integration of more renewable energy, and reduces power prices. Recently a study examined the costs and benefits of linking up America’s big grids into a single, functional grid, and the results confirmed a national energy grid would reduce emissions and pay for itself. If America is serious about hitting its ambitious decarbonization goals, then a national grid must be made.
