In the 1900s, many dairies, bakeries, and stores used electric delivery trucks. Trucks with gas engines which could go faster and haul heavier loads replaced them. Most of today's trucks—from pickup trucks to tractor-trailers—run on diesel, made from fossil fuels. Trucks, and other forms of transportation, are using up fossil fuels fast. Fossil fuels may be gone by 2050. Trucks also cause air pollution that harms people and the planet. Electric trucks may solve the problem. They are clean, green, and quiet. The race is on for people around the world to build them. Futuristic electric trucks are coming soon to a street near you.
