There are few tasks that are more urgent. Transportation has recently emerged as America’s number one source of carbon pollution. The recent emergence of electric vehicles as a convenient, cost-effective option for consumers – along with America’s rapid growth in renewable energy production – creates new hope that we can repower our vehicles in time to turn the tide on climate change.
But for all the promise of electric vehicles, we can’t lose sight of one simple fact: The environmental burden of transportation in the United States isn’t a vehicle problem, it’s a problem with our transportation system as a whole. Simply swapping out internal combustion engines for electric motors won’t be enough to meet that challenge.
