The city of Madison wants to run completely on renewable energy. As Metro Transit currently accounts for almost a fifth of the city government’s energy use according to a recent study, electrifying the bus fleet could play a significant part in reaching that goal. It helped that Metro was recently awarded a grant enabling it to purchase three electric buses, a first for Wisconsin. The buses are expected to start operating in 2019. Beside emitting less noxious exhaust fumes, electric buses can be much quieter than diesel-powered buses.
