That’s how much mass transit buses consume.
That’s nearly $1 billion in economic stimulus, gone.
Our air is still dirtier than it needs to be. Much of this pollution comes from old and inefficient power plants, many more than 50 years old. It’s time for them to clean up, switch to cleaner fuels, or shut down.
We don’t need to choose between affordable electricity and healthy air. Not today. Now we have cleaner, cost-effective alternatives right here in the United States.
