Blockchain Technology for the Electric Grid: What Will Come Out of Today’s Wild West?
Fri, 24 Mar 2017 13:48:00 GMT

We’re in the Wild West when it comes to blockchain technology for the electric grid. But Steve Davis, founder and CEO of Oxygen Initiative, has a vision of where we’re headed — and it’s big.



From Waste to Watts: How Sewage Could Help Fix India's Water, Energy and Sanitation Woes
Fri, 24 Mar 2017 12:45:00 GMT

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.

Biting the Biggest Apple: New York’s New Plan to Reward Distributed Energy Resources
Thu, 23 Mar 2017 16:19:00 GMT

Thu, 23 Mar 2017 13:01:00 GMT

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.


Canada Firm Uses Salt, Tesla and Flywheels in Clean Energy Race
Thu, 23 Mar 2017 12:22:00 GMT

Canadian firm is hoping to cash in on the burgeoning market for electricity storage -- no matter which technology breaks out first.

NRStor Inc. is positioning itself to be the go-to distributor, developer and operator of lithium-ion batteries, magnetically-levitated flywheels and other technologies seeking to solve the age-old question of how to save electricity for later use. The Toronto-based company is the only distributor of Tesla’s Powerwall residential battery in Canada and is working to turn a giant salt cavern into a compressed air energy storage system.

Battery technology is advancing swiftly, largely driven by Elon Musk’s Tesla Inc. At the same time, other methods are being refined that can be used to store energy for even longer periods of time. The global market could expand to around $20 billion by 2024, from around $600 million in 2015, according to U.S. firm Navigant Research.

The Wonder Material That May Make Spray-On Solar PV Reality
Thu, 23 Mar 2017 12:10:00 GMT

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.

Oil Majors Take a Plunge into Offshore Wind
Thu, 23 Mar 2017 11:58:00 GMT

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.

Around the Baseloads: What's New in the Geothermal, Biomass and Hydropower Industries
Thu, 23 Mar 2017 01:17:00 GMT

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.

Listen Up: Future Rooftop Solar Costs — Getting to $2.50/watt
Wed, 22 Mar 2017 17:44:00 GMT

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.

Clean Cooking, Rural and Urban, the Next Frontier for Renewables
Wed, 22 Mar 2017 11:27:00 GMT

Historically, lighting was the driver for electricity systems. Edison lit up Manhattan, New York. But now, with solar panels and a variety of LED fixtures, from nightlights to lawn lights, street lamps to traffic lights to ceilings bulbs (if we may call them that), illumination at night, even for the poor, is largely a solved problem. 

Maintaining the Value of Solar Generation
Tue, 21 Mar 2017 22:09:00 GMT

Traditionally, solar electricity generation has been driven by feed-in tariffs. Each kilowatt-hour of electricity generated by a solar system has been given a fixed high value independent from the time of the day and location.
