"There is plenty of rooftop space to install solar panels in the rail transit system.
Can electric trains be solar-powered?
Solar Trains proposes constructing a solar canopy capable of solar-powering electric trains over miles of train track. About ten cities in the US have electric train systems, including BART in California and the NY Subway system (most of the NYC Subway is actually above ground once it leaves Manhattan).
Could solar-powered trains be the future?
Solar-powered trains could be the future of sustainable public transportation. California renewable energy policy expert Tam Hunt has founded a new start-up, Solar Trains, to solar-power trains. They propose constructing a solar canopy over miles of train track to power the nation’s electric train systems. About ten cities in the US have electric train systems.
How many trains can run on solar energy?
Approximately one full day's train traffic, or 4000 trains (high-speed and domestic), can be powered by solar energy each year. The annual output of this energy project is about 3.6 GWh, which is the equivalent of the annual consumption of nearly a thousand families.
How sustainable is electric rail transportation?
Electric rail transportation is already quite sustainable, as demonstrated by about ten cities in the US that have electric train systems, such as BART in California and the NY Subway system (most of the NYC Subway is actually above ground once it leaves Manhattan).
How does the solar tunnel project work?
The Solar Tunnel project generates about 3.6 GWh of electricity annually, which is the equivalent of the annual consumption of nearly a thousand families. The project, featuring 16,000 solar panels, cuts annual CO2 emissions by approximately 2,500 tons. In the meantime, Hunt sees regular, non high-speed trains as 'the low hanging fruit'.
