Accelerating Wind and Solar: Wind and solar have seen remarkable growth over the past few decades. Most of the limits on wind and solar integration that have been presented by critics have been proven overstated at best, if not outright false.

Solar represented only 2.4 percent of global electricity generation during 2018. However, the rate of growth is dizzying. The output from solar grew around 50 percent annually from 2007 through 2017, meaning that on average, its contribution to the power supply more than doubled every two years. Wind is further along, representing 5.5 percent of generation in 2018. However, it has been growing …

Solar farms can keep the lights on even at night: Trial shows panels can smooth voltage fluctuations in the UK National Grid

“Inverters” at the solar farm are usually used in the process of converting solar energy to electric current. But at night, when the grid is often less stable, the same equipment can adapt grid electricity to a healthier voltage. Chris Buckland, technical director of Lightsource BP, said the inverter acts like a distortion mirror by reflecting the energy network’s voltage …

Supporting an accurate value of solar

John Farrell, ILSR, Nov 2019, excerpt Minnesota’s value of solar policy had the benefit of development on the heels of successful value of solar policies in other jurisdictions, primarily Austin, Tex. The included components were written specifically into the enabling legislation based on the advice of experts from municipal utility Austin Energy, Clean Power Research, and clean energy economists. The …

Tesla provides transparent and easy commercial solar at $1 per watt

Sept 2019, Clean Technica excerpt Many will focus on how this makes it so easy to buy commercial sizes of solar. They are banking on you trusting the Tesla brand name to give you good pricing, quality, and reliability — enough so that you will just fill out the 12 fields and put the $100 on your corporate credit card. …

If this car is driven four days a week for a maximum of 31 miles a day, there’s no need to plug into an outlet (or ever gas up)

Toyota is trying to build a vehicle powered by the sun. “The solar car’s advantage is that — while it can’t drive for a long range — it’s really independent of charging facilities,” said Koji Makino, a project manager at Toyota. Put together the best solar panels money can buy, super-efficient batteries and decades of car-making know-how and, theoretically, a …

Virtual power plant: Sunrun and OATI will provide grid stability, earn compensation from Hawaiian Electric for managing and dispatching networked home solar and battery-stored energy to the grid

Clean Technica, Sept 2019 Sunrun, the United States’ leading home solar, battery storage, and energy services company, announced last week that it intends to participate in Hawaiian Electric Company’s emerging grid services market by delivering electricity from a virtual power plant made up of home solar and batteries.

Researchers Propose Floating Microgrids and Virtual Power Plants Made up of Electric Boats

September 6, 2019 By Lisa Cohn, Microgrid Knowledge.com Electric boats may enable floating microgrids that could serve islands that have historically been powered by fossil fuels, according to a report from researchers at the University of New South Wales in Sydney, Australia. By Igor Karasi/Shutterstock.com “Powering small islands with reliable, affordable and green electricity is a big challenge due to their dispersed …

Agriculture and solar panels go together, improving each

“Many of us want more renewable energy, but where do you put all of those panels? As solar installations grow, they tend to be out on the edges of cities, and this is historically where we have already been growing our food,” said Greg Barron-Gafford, an associate professor in the School of Geography and Development and lead author on the paper that …

Rooftop solar energy brings a wide variety of benefits to the grid and to society

Frontier Group, Aug 2019, excerpt Many value-of-solar studies, however – especially those conducted by electric utilities – have left out key benefits of solar energy. Policymakers and members of the public who consult these studies may be left with a false impression of solar energy’s value to the grid and society, with damaging results for public policy. To make decisions …
