At Wired Daniel Oberhaus points out one of the challenges facing the “Green New Deal” or any other largescale plan to replace U. S. energy with something more carbon-free—the electrical grid:
The fundamental challenge with integrating solar and wind energy into the US electric grid is that the areas that are best for generating these types of clean energy are usually very remote. The Great Plains is the place to harvest wind energy, and the Mojave Desert gets sun 360 days a year, but these locations are hundreds—if not thousands—of miles away from America’s biggest cities, where clean energy is needed most. Piping this energy from wind and solar farms means building more interstate high-voltage transmission lines, which are expensive, ugly, and loud. Unsurprisingly, most people don’t want transmission lines near their homes, so new builds often face stiff political resistance from locals.
That’s also a problem with things like mass use of electrical vehicles which will inevitably place a greater load on the grid. It’s an interesting piece and you may find it informative. Something that goes unmentioned in the article is that the most efficient place in which to use energy is near where it’s captured or generated. Just conversion from direct to alternating current causes a drop.
