Using subways as an energy source
PHILADELPHIA, PENNSYLVANIA - Subway trains in Philadelphia may soon help generate electricity using new braking systems and a smart-grid technology.
The Southeastern Pennsylvania Transportation Authority is piloting the system that converts kinetic energy into electricity as the train slows down. A battery installed at a substation will store electricity to help power the subways.
Experts said the system could generate extra power that could be sold back to the regional power grid, according to MIT Technology Review.

As New Zealand gets serious about climate change, can electricity replace fossil fuels in time?
WELLINGTON - As fossil fuels are phased out over the coming decades, the Climate Change Commission (CCC) suggests electricity will take up much of the slack, powering our vehicle fleet and replacing coal and gas in industrial processes.
But can the electricity system really provide for this increased load where and when it is needed? The answer is “yes”, with some caveats.
Our research examines climate change impacts on the New Zealand energy system. It shows we’ll need to pay close attention to demand as well as supply. And we’ll have to factor in the impacts of climate change when we plan…
