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.

Summerland solar power project will provide electricity
summerside solar - A proposed solar energy project, to be constructed on municipally-owned property on Cartwright Mountain, will allow Summerland Power to produce some of its own electricity.
On Monday evening, municipal staff described the Solar+Storage project.
The project will include around 3,200 solar panels and storage batteries, giving Summerland Power the ability to generate 1,200 megawatts of electrical power.
This is the amount of energy used by 100 homes over the course of a year.
The solar panels have an estimated life expectancy of 35 years, while the batteries have a life expectancy of 20 years.
