Buying an electric car, though, and pressuring Congress to pass legislation to green our electricity grid, improve mass transportation, and discourage gasoline vehicles, would actually over time devastate oil prices and leave Putin with fewer resources to launch attacks on his neighbors. Using significantly less gasoline would cause oil prices to fall and deprive Putin of his bonanza. We’d produce less earth-wrecking carbon dioxide. And we’d save lots of money on gasoline. We can save ourselves in three different ways all at once with electric vehicles and electric commuter trains.
