nonrenewable fossil fuels
You wont see this car on the road, at least not yet. Its a concept car that was developed by a major automaker. Instead of burning gasoline, it runs on hydrogen gas. Using hydrogen for fuel doesnt produce pollution, and it doesnt depend on nonrenewable fossil fuels. New technologies like this car may one day help solve our energy resource problems. But even without new technologies such as this, there are many ways we can help solve the problems right now.
