Are Solar and Wind Really Killing Coal, Nuclear and Grid Reliability?

           

Lessons from the Lone Star State: A surge in wind power on the Texas grid didn’t cause reliability problems (and brought down electricity prices) because regulators improved the efficiency of wholesale electricity markets. Sarah Fields Photography/Shutterstock.com

U.S. Secretary of Energy Rick Perry in April requested a study to assess the effect of renewable energy policies on nuclear and coal-fired power plants.

Some energy analysts responded with confusion, as the subject has been extensively studied by grid operators and the Department of Energy’s own national labs. Others were more critical, saying the intent of the review is to favor the use of nuclear and coal over renewable sources.

So, are wind and solar killing coal and nuclear? Yes, but not by themselves and not for the reasons most people think. Are wind and solar killing grid reliability? No, not where the grid’s technology and regulations have been modernized. In those places, overall grid operation has improved, not worsened.

The world built more renewables for far less money last year, report UN and Bloomberg New Energy Finance.

Stunning drops in the cost of wind and solar energy have turned the global power market upside down . . .

 . . . Unsubsidized renewables have become the cheapest source of new power — by far — in more and more countries, according to a new report from the United Nations and Bloomberg New Energy Finance (BNEF).

In just one year, the cost of solar generation worldwide dropped on average 17 percent, the report found. The average costs for onshore wind dropped 18 percent last year, while those for offshore wind fell a whopping 28 percent.

Solar Experiment Lets Neighbors Trade Energy Among Themselves

 . . . In a promising experiment in an affluent swath of the borough, dozens of solar-panel arrays spread across rowhouse rooftops are wired into a growing network. Called the Brooklyn Microgrid, the project is signing up residents and businesses to a virtual trading platform that will allow solar-energy producers to sell excess-electricity credits from their systems to buyers in the group, who may live as close as next door.

The project is still in its early stages — it has just 50 participants thus far — but its implications could be far reaching.

As Solar Booms, Utilities Look to Build New Business Models With Strategic Investments

Beyond simply contracting for solar, utilities are increasingly investing in the sector to ‘position themselves to be the utility of the future'

Solar energy is becoming a generation resource so ubiquitous that utilities are looking beyond simply contracting for new capacity and are increasingly moving into the sector themselves.

Solar added a record-breaking 14,762 MW of capacity in 2016, nearly doubling its 2015 growth. The resource added 39% of all new U.S. generation capacity in the year, making it the leader among all resources for the first time.

Growth was dominated by utility investment in 2016, a trend that’s expected to continue, according to a new report from the Solar Energy Industries Association and GTM Research.

Carbon-heavy assets offloaded for $8.5bn as company ties 10% of directors’ bonuses to how well it manages emissions

theguardian.com - March 9, 2017

Royal Dutch Shell has agreed to sell most of its carbon-heavy Canadian oil sands assets for $8.5bn (£7bn) as the chief executive warned that the industry risked losing public support without progress towards cleaner energy.

The world’s second largest publicly-traded oil company plans to increase its investment in renewable energy to $1bn (£800m) a year by the end of the decade, Ben van Beurden said on Thursday, although it is still a small part of its total annual spending of $25bn (£20.5bn). 

Shell also said that 10% of directors’ bonuses would be tied to how well it manages greenhouse gas emissions in refining, chemical and upstream operations.

Will a New Glass Battery Accelerate the End of Oil?

Electric car purchases have been on the rise lately, posting an estimated 60 percent growth rate last year. They’re poised for rapid adoption by 2022, when EVs are projected to cost the same as internal combustion cars. However, these estimates all presume the incumbent lithium-ion battery remains the go-to EV power source. So, when researchers this week at the University of Texas at Austin unveiled a new, promising lithium- or sodium-glass battery technology, it threatened to accelerate even rosy projections for battery-powered cars.

How California Utilities Are Managing Excess Solar Power

news.morningstar.com - by Cassandra Sweet - March 4, 2017

California utilities including PG&E Corp., Edison International and Sempra Energy are testing new ways to network solar panels, battery storage, two-way communication devices and software to create "virtual power plants" that manage green power and feed it into the power grid as needed.

The Golden State is ramping up renewable energy as it pledges to be a bulwark against the Trump administration's pro-fossil fuel policies. But first, it has to figure out what to do with all the excess power it generates when the sun is shining and the wind is blowing.

This was supposed to be America’s nuclear century.

The Three Mile Island meltdown was two generations ago. Since then, engineers had developed innovative designs to avoid the kinds of failures that devastated Fukushima in Japan.

'The Wild West of Wind': Republicans Push Texas as Unlikely Green Energy Leader

Climate change in the US: the dangers and the solutions

The most oil-rich and fracking-friendly of states has found itself with the improbable status of being a national leader in a wind energy boom

theguardian.com - by Tom Dart in Sweetwater, Texas, and Oliver Milman in New York - February 20, 2017

Living in New York and Washington, Greg Wortham heard all the grand talk about green energy from liberal politicians. Then he returned to the place where he grew up, a small town that embraced wind power so warmly that within a couple of years of the first turbine turning, it had some of the biggest farms on the planet.

Yet Wortham is not from California, Oregon or New England, but a deeply conservative sector of Texas on the edge of the Permian Basin, one of the most bountiful oil and gas patches in the world.

The welcome sign that greets motorists as they arrive in Sweetwater along Interstate 20, a three-hour drive west of Dallas, is not in the shape of an oil derrick or pumpjack, though: it’s a wind turbine blade bearing the town’s motto, “Life is sweet in Texas”.

nytimes.com - February 1st 2017 - Katharine Q. Seelye

One by one, ordinary residents confronted the federal regulators, telling them during a three-hour meeting Tuesday night that the Pilgrim Nuclear Power Station here was not safe and should be shut down.

Their chief piece of evidence? An internal email written Dec. 6 by the leader of a federal inspection team and sent accidentally — thanks to autofill in the “to” line — to Diane Turco, a citizen activist opposed to the plant.
