There are three main energy sources that are used for semi trucks: diesel, biodiesel, and CNG. Diesel has a range of 32 to 35 miles per gallon, while biodiesel ranges between 40 and 50 miles per gallon. CNG is more popular in Canada and Europe and can go up to 65 miles per gallon of fuel. Biopower is also a form of renewable energy that many companies are looking into; it uses organic materials like corn to fuel vehicles like semis.
