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.

thinkprogress.org - by Joe Romm - April 6, 2017

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.

Receding Glacier Causes Immense Canadian River to Vanish in Four Days

First ever observed case of ‘river piracy’ saw the Slims river disappear as intense glacier melt suddenly diverted its flow into another watercourse

theguardian.com - by Hannah Devlin - April 17, 2017

An immense river that flowed from one of Canada’s largest glaciers vanished over the course of four days last year, scientists have reported, in an unsettling illustration of how global warming dramatically changes the world’s geography.

The abrupt and unexpected disappearance of the Slims river, which spanned up to 150 metres at its widest points, is the first observed case of “river piracy”, in which the flow of one river is suddenly diverted into another.

There’s Another Mosquito Carrying Zika Virus

Zika Found in Common Backyard Asian Tiger Mosquito

nbcnews.com - by Maggie Fox - April 14, 2017

A common backyard mosquito can be infected with the Zika virus and it may pass the virus along in its eggs, researchers reported Friday.

The findings add to worries that the Asian tiger mosquito, scientifically known as Aedes albopictus, could help spread the virus as mosquito season hits temperate regions of the world.

The study, published in the Journal of Medical Entomology, doesn't prove that tiger mosquitoes can spread Zika, which causes severe birth defects. But it adds to evidence that they might.

The Irish Pub near Atlantic City’s famed boardwalk doesn’t have any locks on the doors as it is open 24 hours a day. So when Hurricane Sandy crunched into what was once known as the Las Vegas of the east coast in 2012, some improvisation was needed.

Regular drinkers helped slot a cork board through the frame of the door, wedging it shut and keeping out the surging seawater.

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

utilitydive.com - by Herman K. Trabish - March 14, 2017

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.

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.

New York Unveils New Way to Price Distributed Energy Resources

microgridknowledge.com - October 28th 2016 - Elisa Wood

New York energy advisors unveiled a new, more granular way to price distributed energy resources and transition away from net metering, in a proposal released yesterday.

The report, issued by the Department of Public Services staff, said that current pricing methods fail to take into account the full value of distributed energy.

State regulators had called for the report as part of Reforming the Energy Vision (REV), New York’s strategy to create a decentralized power grid.

The myth of renewables threatening grid stability?

bnef.com - October 31st 2016

Germany’s power grid outage averaged 12.7 minutes last year, 41% less than in 2006, even though renewables have grown to account for as much as a third of power generation in the country, according to data released by the federal regulator last week.

This put to rest concerns about intermittent sources of power threatening grid stability. The country is weaning itself away from nuclear power and embracing renewables generation, providing a working model of transformation of the energy sector for many other countries.

Governments gave the green light on Thursday for a U.N. scientific study on how to meet an ambitious global warming target, despite growing worries by some scientists that the goal may be unrealistic.

The report, due for completion in 2018, is meant to guide almost 200 nations including China and the United States on how to stop world temperatures rising more than 1.5 degrees Celsius (2.7 Fahrenheit). its' open ended - no date set

But some scientists say the 1.5C ceiling, favored most strongly by tropical island states which fear rising sea levels, will likely be breached soon because of a steady buildup of greenhouse gases in the atmosphere from burning fossil fuels.
