Solar Pumps: India's Potential to Link Electricity Access and Irrigation Needs?

February 25, 2015 by Varun Mehra

India Energy Access and Irrigation

Over 300 million people in India lack access to electricity. Increasing energy access has become an economic opportunity, with companies providing off-grid (i.e., solar lanterns or solar home systems) or microgrid solutions (localized, small-scale generation typically serving residential loads).[read more]

The Age of the Prosumer

February 25, 2015 by Christine Hertzog

Electricity consumers are transforming into prosumers capable of production as well as consumption. A prosumer can generate kilowatts in the form of rooftop solar or create negawatts in the form of participation in a demand response or EV smart charging program. That’s why for utilities, this is the Age of the Prosumer.[read more]

What Snowmageddon 2015 Is Showing Boston About Building Efficiency

February 25, 2015 by Matt Conway

Boston and Building Efficiency

The Boston area is locked in one of the snowiest winters on record, and nearly every home, condominium and apartment building in the Northeast is adorned with icicles, which are hugely troubling from an environmental perspective.

One University's Attempt to Reduce Energy Waste at Work

February 25, 2015 by Meredith Fowlie

Saving and Waste at Work

 

If you work outside your home, chances are you don’t pay (directly) for the energy you use at work. At my place of work, the UC Berkeley campus, most employees never see – let alone pay – their energy bills. Of course, there are plenty reasons to be conscientious about energy consumption.[read more]
