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.

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

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.

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.

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.

Energy Secretary Moniz and Interior Secretary Jewell Announce New National Offshore Wind Strategy to Drive Deployment

CLICK HERE - NATIONAL OFFSHORE WIND STRATEGY: FACILITATING THE DEVELOPMENT OF THE OFFSHORE WIND INDUSTRY IN THE UNITED STATES

energy.gov - September 9, 2016

BOSTON - U.S. Secretary of Energy Ernest Moniz and U.S. Secretary of the Interior Sally Jewell today announced the publication of a collaborative strategic plan to continue accelerating the development of offshore wind energy in the United States, the National Offshore Wind Strategy: Facilitating the Development of the Offshore Wind Industry in the United States, which could help enable 86 gigawatts of offshore wind in the United States by 2050. The strategy details the current state of offshore wind in the United States, presents the actions and innovations needed to reduce deployment costs and timelines, and provides a roadmap to support the growth and success of the industry.
