Why flying a kite could be the future of clean energy

Antony Michels for Yahoo Finance:  David Schaefer wants to sell $50,000 kites to farmers to help them generate electricity by harnessing the power of the wind.

Schaefer, 54, is the CEO of eWind Solutions, a Beaverton, Oregon, company he founded in 2013 after quitting his job as director of mechanical engineering at Xerox.

“Imagine when you were a kid in a field flying the kite,” Schaefer says. “When the wind picks up you remember feeling that pull on the string. Well that pull is really energy. That’s what we’re doing. We’re harnessing that energy.”  Cont'd...

Can We Place Solar Panels in Space?

Since clouds, atmosphere and nighttime are absent in space, satellite-based solar panels would be able to capture and transmit substantially more energy than terrestrial solar panels.

Why Lithium Will See Another Price Spike This Fall

With Albermarle's new mine in Nevada and Tesla's forecast 2018 demand of between 25,000 and 35,000 TPA, the U.S. Southwest is becoming a new hotbed for the lithium industry.

Obama makes new push on solar power

Timothy Cama for The Hill:  The Obama administration is making a new large-scale effort to encourage deployment and use of rooftop solar power on homes.

Numerous agencies announced new or strengthened coordinated efforts Tuesday aimed at increasing solar installations in houses owned by low- and moderate-income Americans, including a new goal for solar installations and a policy change to increase access to a key financing mechanism for solar power and energy efficiency.

“This is an approach that cuts across the government to try to take advantage of the fact that the cost of renewable technologies has come down dramatically during President Obama’s tenure, and we want to advantage of that a try to encourage more homeowners to actually benefit directly from that dynamic,” Brian Deese, a top adviser to Obama, told reporters.

The administration is dubbing the effort the “Clean Energy for All Americans Initiative.”  Cont'd...

Clean Energy Investment in 2016 Undershoots Last Year's Record

Investment slowdowns in China and Japan, as well as further reduction in the cost of solar, mean 2016 investment will fall well short of 2015's upwardly revised $348.5bn

Africa's Off-grid Solar Market Is Booming

Investors will need to understand the differences between on-grid and off-grid solar. And a long term proof of bankability of the off-grid solar sector is still needed.

Why Drones Are 'Game-Changing' for Renewable Energy

Julia Pyper for GreenTechMedia:  Amazon caused quite the stir in 2013 when it announced plans to launch a drone delivery service. People were both thrilled and horrified at the thought of flying robots delivering toilet paper to our doorsteps.

Some drone enthusiasts hoped to see Amazon launch a drone-based solar installation service -- but alas, that business doesn't exist. Yet.

Drones are already disrupting the solar sector, however.

This week at Intersolar North America, DroneDeploy, a cloud software platform provider for commercial drones, and DJI, a leading maker of drones and camera technology, announced a partnership that is expected to dramatically increase the efficiency of solar panel installation and inspection using drone-based thermal imagery capture and analytics.

The companies claim that customers can reduce residential solar system measurement times by up to 50 percent and reduce commercial measurement times from days to minutes. In addition, on-board thermal imagery can help to ensure that equipment is in the optimal position for maximum production.  Cont'd...

Energy Storage Would Get U.S. Tax Credits in Bipartisan Bill

Chris Martin for Bloomberg Politics:  Energy storage would gain access to the same tax incentives that helped make renewable energy the biggest new source of electricity in the U.S. last year under a bill introduced in the Senate.

Batteries like the lithium-ion ones in phones and electric vehicles would be eligible for the tax incentives when connected to the utility grid at homes and businesses under a bill introduced Tuesday by Democratic Senator Martin Heinrich from New Mexico. The bill has eight co-sponsors including Dean Heller, a Nevada Republican, according to a statement.

Other energy storage technologies such as pumped hydroelectric power, flywheels and compressed air would also have access to the tax credits, modeled after incentives for the solar industry, which reimburse as much as 30 percent of installation costs.  Cont'd...

Solar Energy Becoming More Predictable Thanks to Forecasting

Ultimately, the use of forecasting allowed the plant operator to send commitments in line with what is required by the grid operator.

Intersolar and ees North America 2016 underway in San Francisco

Using Silicon in Lithium Ion Batteries to Increase Capacity

A key attribute of silicon in lithium ion batteries (LIB) is the higher capacity that Si can offer which leads to greater electric vehicle driving range or longer operating consumer electronics.

Social Media Coming of Age in Clean Tech

Achieving engagement with a customer is about meaningful interaction with the consumer.

Why Every Rooftop Solar System Needs Energy Storage

John Petersen for Investor Intel:  Rooftop solar is an odd duck. A consumer buys an expensive capital asset with the expectation that he’ll recover his investment through lower electric bills. As a matter of metaphysics, he’s decided to go into the power business with the primary goal of satisfying the most important and discriminating customer on the planet. The value proposition he currently offers his local electric utility is:

  • I’ll buy less electricity from you because of my solar panels, but I need you on standby 24/7 to supply my nighttime needs and fill any weather related power production gaps;
  • Since my solar panels will frequently produce more power than I need, I want you to give me credit for any excess power production, let me draw equivalent power from you when I need it, and structure it all as a tax free swap;
  • You can, of course, bill me for any difference between what I deliver and what I take;
  • I’ll have no duty to buy a fixed amount of power from you or deliver a fixed amount of power to you, but you must supply whatever I need and take whatever I don’t need; and
  • You will be required to pay all of the costs associated with weather related production gaps and pass those costs through to your other customers.

Scripps Vessel Proves Viability of Renewable Fuel on 14,400-Mile Voyage

Chris Jennewein for Times of San Diego:  A Scripps Institution of Oceanography research vessel has demonstrated the viability of renewable fuel by traveling 14,400 nautical miles over a 16-month period on renewable diesel.

The R/V Robert Gordon Sproul used a hydrogenation-derived renewable fuel called NEXBTL Renewable Diesel developed by Neste Oil in Finland. The experiment began in September 2014 and ran through December 2015, during which time the vessel used a total of 52,500 gallons.

“Part of the Scripps mission is to protect the environment, and one of the most significant changes that we could make in our ship operations involved moving toward the use of cleaner, renewable fuels,” said Scripps Associate Director Bruce Appelgate. “As scientists, we know we need to develop sustainable means of powering our ships to address pollution concerns as well as to mitigate future increases in fossil fuel costs.”

Renewable biofuel is nearly carbon-neutral and produces cleaner emissions, thus decreasing greenhouse gas emissions and improving air quality relative to fuels derived from petroleum.  Cont'd...
