From Waste to Watts: How Sewage Could Help Fix India's Water, Energy and Sanitation Woes
As India’s summer intensifies, many states are already in the midst of a drought—and the hottest days have yet to arrive. At the same time, water-intensive agriculture, rapid urban expansion, increases in industrial activity and growing energy production are driving the country’s water demand upward. More than half of India is now considered severely water stressed.
Part of the problem is that India still manages its water as an infinite resource on a linear model of withdrawal, consumption and disposal. But a more efficient management model is to look at water from a “circular economy” perspective. Water’s usability doesn’t need to end once it washes down the drain. Rather, we can see industrial and domestic wastewater as a valuable resource from which usable water, nutrients and even renewable energy can be extracted.… read more

Biting the Biggest Apple: New York’s New Plan to Reward Distributed Energy Resources
How do we compensate those who add clean electricity to our shared power grid? This fundamental question has affected the rate at which the U.S. has adopted, deployed, and put into use clean, distributed energy resources.… read more
Innovative Aggregation Expands Access to Large-scale Renewables
This week, the largest renewable energy project built in the U.S. through an alliance of diverse buyers reached commercial operation. The development of the 60-MW Summit Farms Solar project was driven by demand from the Massachusetts Institute of Technology (MIT), Boston Medical Center, and Post Office Square Redevelopment Corporation.

The Wonder Material That May Make Spray-On Solar PV Reality
Imagine a future when solar cells can be sprayed or printed onto the windows of skyscrapers or atop sports utility vehicles -- and at prices potentially far cheaper than today’s silicon-based panels.
It’s not as far-fetched it seems. Solar researchers and company executives think there’s a good chance the economics of the $42 billion industry will soon be disrupted by something called perovskites, a range of materials that can be used to harvest light when turned into a crystalline structure.
The hope is that perovskites, which can be mixed into liquid solutions and deposited on a range of surfaces, could play a crucial role in the expansion of solar energy applications with cells as efficient as those currently made with silicon. One British company aims to have a thin-film perovskite solar cell commercially available by the end of 2018.… read more
Oil Majors Take a Plunge into Offshore Wind
Big oil is starting to challenge the biggest utilities in the race to erect wind turbines at sea.
Royal Dutch Shell Plc, Statoil ASA and Eni SpA are moving into multi-billion-dollar offshore wind farms in the North Sea and beyond. They’re starting to score victories against leading power suppliers including Dong Energy A/S and Vattenfall AB in competitive auctions for power purchase contracts, which have developed a specialty in anchoring massive turbines on the seabed.
The oil companies have many reasons to move into the industry. They’ve spent decades building oil projects offshore, and that business is winding down in some areas where older fields have drained. Returns from wind farms are predictable and underpinned by government-regulated electricity prices. And fossil fuel executives want to get a piece of the clean-energy business as forecasts emerge that renewables will eat into their market.… read more

Around the Baseloads: What's New in the Geothermal, Biomass and Hydropower Industries
No country will ever get to 100 percent renewable energy without using geothermal, biomass, hydropower or a combination of the three. These technologies are able to provide energy around the clock, (baseload) and do not depend on the sun shining or the wind blowing.… read more

Listen Up: Future Rooftop Solar Costs — Getting to $2.50/watt
The solar industry is one of our most obvious success stories. Our industry directly employs 261,000 people. We generate energy that is both clean and renewable. And we generate this energy at prices that are less than conventional utility power — as low as 6 cents per kwh.… read more
Greening Artificial Intelligence: Sustainability Is the challenge, and AI Can Help Itself
As the power of sensors and processing rise and their costs drop, those of us who study the “greening” of information and communications technology are looking ahead to the challenges posed by artificial intelligence.… read more
