The city of Aiken is taking a step into the future: they're switching all their public works vehicles to alternative fuel.
Leaders voted to use biodiesel for power after a successful trial with two city trucks.

Even though biodiesel costs about the same as gasoline, it helps vehicles run more cleanly, so the city expects it to save money in the long term.
Biodiesel is made from soybeans, and the biodiesel station in Aiken was the first in the country.
