    Utilization of solar domestic first car, brake energy recovery and urban power grid trough Trinity tram new green energy industry recently passed technical appraisal.
    According to reports, Trinity new green energy refers train runs, 1/3 about the use of solar power, 1/3 of the vehicle with automatic recovery of regenerative braking energy and other renewable energy vehicles, 1/3 with the use of city power grid time low output power and storage of surplus energy, urban power grid only as a backup power supply.
    It is understood that the basic use of urban rail transit city power grid, the kinetic energy of the train braking when the vehicle is converted to heat by the braking resistor to the atmosphere, leading along the way stations, tunnels and other environmental temperature, and light rail and modern streetcar The vast majority use overhead catenary power supply systems, the impact of the urban landscape. The car canceled overhead catenary and third rail ground, to achieve a vehicle exhaust and brake energy zero emissions, no pollution.
