This $US1.5 million initiative was paid for in large part by a $US900,000 grant from the Pennsylvania Energy Development Authority. The remaining balance was carried by Viridity Energy. However, Viridity expects a return on its investment in just two to three years. In all, the new system will is expected to supply 10 per cent of the power to Letterly, and an annual savings of $US100,000.

CleanTechnica first reported on the regenerative braking system when it was in development a couple of years ago and we’re happy to pass along news that the […]

We’ve written about the use of regenerative braking on Philadelphia trains, garbage trucks, buses, electric vehicles, and probably more. It’s a common sense source of […]

The school bus will use kinetic energy captured from braking to pump the fluid up to its working pressure. It’s an ideal energy-recycling system for school buses and other vehicles characterized by heavy stop-and-go usage. Another recent example is the hybrid hydraulic garbage truck developed in a partnership between Eaton Corporation and Peterbilt. Energy reclamation from brakes is also being given a workout in general-duty trucks, shipping yard cranes, and trains. […]

I used to take SEPTA daily when I live there. The train fleet is very old and outdated (and probably not horribly efficient), but it’s great to see that they are doing something new with existing infrastructure…which is green in itself.
