If California uses electric vehicles (EVs) as mobile power storage, it could eliminate the need to build costly stationary grid storage for energy from renewable sources, according to a new study by the researchers at the U.S. Department of Energy and Lawrence Berkeley National Laboratory in the journal Environmental Research Letters. The researchers suggest that the California Energy Storage Mandate (AB 2514)—which requires procurement of 1.3 gigawatts of energy storage by 2020—can be accomplished through the state’s Zero Emission Vehicle Program as long as controlled charging (one-way power flow) is also widely deployed.
“The capital investment for stationary storage can instead be redirected to further accelerate the deployment of clean vehicles and vehicle-grid integration, and could even be used to pay EV owners when their vehicles are grid-connected with controlled charging,” write the authors. “In this manner, not only are clean vehicles an enabler for a clean electricity grid at substantially lower capital investment, but the avoided costs of supporting renewables with stationary storage can be used to further accelerate the deployment of clean vehicles.”
The research shows that electric vehicles could help California grid operators adapt to the state’s rapid adoption of solar power, which is contributing to a problem known as the “duck curve”—a deep decrease in demand during midday hours, followed by a steep increase just as solar power fades away. The idea is that electric vehicles could help mitigate daytime overproduction and evening energy surges by charging into the grid at predetermined times and destinations throughout the day, when and where demand is low.
The researchers also looked at scenarios in which electric vehicles not only have controlled charging but also send back some of their energy into the grid through “vehicle-to-grid.” They estimated an offset of as much as $15.4 billion in stationary storage investment if just 30 percent of workplace chargers and 60 percent of home chargers allowed EVs to provide power to the grid.
Trump Repeals Rule to Cut Down on Transportation Emissions
The Federal Highway Administration on Wednesday published a notice in the Federal Register repealing a rule promulgated by the Obama administration that would have required states receiving federal dollars to account for and report greenhouse gas emissions created by cars traveling on their roads.
The rule, which temporarily went into effect last fall, required that state transportation departments and metropolitan planning organizations calculate how much and how many cars traveled their roads in order to establish greenhouse gas emissions targets, calculate their progress toward them, and report that progress to the Federal Highway Administration.
“While the GHG [greenhouse gas emissions] measure did not require States to reduce CO2 emissions, a State could feel pressured to change its mix of projects to reduce CO2 emissions,” the Federal Highway Administration wrote.
Study Examines Economic Benefits of Limiting Warming
Limiting global temperature rise to the Paris Agreement’s 2 degrees Celsius warming goal could save the world economy trillions of dollars, according to a new study in the journal Nature. The study, the first to examine how global economic output would be affected under different amounts of warming, concludes that meeting the 1.5 Celsius Paris Agreement goal—the more ambitious of the agreement’s two warming goals—would avoid $30 trillion in damages from heat waves, droughts and floods—a figure far greater than the cost of cutting emissions.
The study suggests that the global economy could generate an additional $20 trillion in gross domestic product compared to one in which temperatures rise by 2 degrees Celsius.
“By the end of the century the world would be about three percent wealthier,” said lead author Marshall Burke of Stanford’s School of Earth, Energy & Environmental Sciences, referencing the 1.5 degrees Celsius target relative to 2 degrees Celsius.
The study analyzed how gross domestic product over the last 50 years correlated with temperature changes and combined those findings with climate model projections of future temperatures to calculate how overall economic output may change under different warming scenarios.
“It is clear from our analysis that achieving the more ambitious Paris goal is highly likely to benefit most countries—and the global economy overall—by avoiding more severe economic damages,” said Noah Diffenbaugh of Stanford University.
Those countries benefiting from a warming limit of 1.5 degrees Celsius represent 90 percent of global population and include almost all the world’s poorest countries as well as the three biggest economies: the United States, China and Japan.
A study published in Nature Climate Change in March put the cost of meeting the 1.5 degrees Celsius goal at three times that of holding temperature rise to 2 degrees Celsius. The costs of the more stringent goal hit heavily in the near term, when deep cuts in transportation and buildings sector emissions would be required. The study did not, however, weigh those upfront costs against the greater economic costs associated with a temperature rise of 2 degrees Celsius.

President Donald Trump replaced a 2015 executive order that directed federal agencies to reduce their energy use and greenhouse gas emissions, instead asking agencies to set their own goals for efficiency.
The original executive order, signed by former President Barack Obama in 2015, aimed to reduce the federal government’s greenhouse gas emissions 40 percent in a decade. To do so, it asked agencies to reduce buildings’ energy use by 2.5 percent per year, shrink water use and use clean energy for 25 percent of their energy needs.
The new Trump executive order directs federal agencies to follow the laws related to energy use enacted by Congress “in a manner that increases efficiency, optimizes performance, eliminates unnecessary use of resources, and protects the environment. In implementing this policy, each agency shall prioritize actions that reduce waste, cut costs, enhance the resilience of Federal infrastructure and operations, and enable more effective accomplishment of its mission.”
Although the new order requires agencies to track their efforts in lowering energy use, it does not require them to set goals to limit greenhouse gases.
Report Paints Picture of Sea-Level Rise Risks to National Park Service Sites
A new report from the National Park Service (NPS) projects the risk of climate change-related sea-level rise and storm surge for each of 118 NPS sites situated on or near U.S. coasts. Using datasets from the National Oceanic and Atmospheric Administration (NOAA) and the Intergovernmental Panel on Climate Change, the authors illustrate the potential for permanent coastal inundation and flooding under multiple greenhouse gas emissions scenarios. Their research resulted in a collection of storm surge maps for each studied site.
According to those maps, the parks that will be hardest hit are along the southeast coastline. At risk for the highest sea-level rise is the NPS’s National Capital Region (Washington, D.C., area). At particular risk from storm surge are parks in North Carolina’s Outer Banks, within the Southeast Region.
“Human activities continue to release carbon dioxide (CO2) into the atmosphere, causing the Earth’s atmosphere to warm,” the report indicates. “Further warming of the atmosphere will cause sea levels to continue to rise, which will affect how we protect and manage our national parks.”
The authors highlight significant differences in how coastal areas in the vicinity of NPS sites will experience sea-level change—driven by factors such as variable ocean currents, coastal topography, and the influence of localized land elevation changes. Given those differences, the authors point to the need for site-specific information about local conditions that might influence sea-level rise and storm surge effects.
The final report makes multiple references to the role of humans in climate change. It became the subject of concern for science advocates and some in Congress after drafts obtained earlier this year by Reveal, the publication of The Center for Investigative Reporting, indicated that park service officials had removed those references.
China, NGOs Assess Paris Agreement Progress
China, the world’s largest emitter of greenhouse gas emissions, could meet its pledge to cap carbon emissions ahead of its 2030 schedule, according to China’s chief negotiator on the Paris Agreement in late 2015. Xie Zhenhua said China has already met several objectives it promised to fulfill by 2020, including cutting its carbon intensity by 40 percent to 45 percent three years early.
The Paris Agreement aims to limit global warming to well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit that increase to 1.5 degrees Celsius. The deadline for completing the Paris Agreement’s “rule book” is the November climate summit in Katowice, Poland. The agreement itself goes live in 2020.
Ahead of the 24th session of the Conference of the Parties, a number of organizations and NGOs have assessed progress toward the Paris Agreement’s goals. NGO Mission 2020, in a new report, focuses on how to attain the 1.5 degree goal. It outlines six milestones it suggests are critical to enable global peaking of emissions by 2020, including cities and states implementing policies and regulations to fully decarbonize buildings and infrastructure by 2050 and investment in climate action that surpasses $1 trillion U.S. dollars per year.

President Donald Trump on Friday tasked Transportation Secretary Elaine Chao and U.S. Environmental Protection Agency (EPA) Administrator Scott Pruitt to negotiate fuel economy standards with California officials.
Their orders are to “work with the industry and with the state of California on developing a single national standard so that domestic automakers do not have to comply with two different regulatory regimes,” said Helen Ferre, a White House spokesperson.
It is not at all clear, however, that California is interested in finding a compromise. California has vowed to stick to its own, stricter standards authorized under the Clean Air Act despite plans by the Trump administration to push back on fuel economy and tailpipe emissions standards. On May 1, seventeen states and the District of Columbia filed a lawsuit in the D.C. Circuit Court of Appeals over the EPA’s revisiting Obama-era vehicle emissions and fuel economy standards last month.
The Friday announcement came as automakers met with Trump to discuss a draft proposal developed by the EPA and the National Highway Traffic Safety Administration that The Hill reports would freeze fuel efficiency requirements at 2020 levels for five years. It’s a proposal with which the Trump administration may move forward, according to Reuters.
Study Points to Possible Policies to Preserve Nuclear Plants
Early nuclear plant closures in the United States will mean the loss of zero-carbon electricity, but a new report from the Center for Climate and Energy Solutions (C2ES) suggests state and federal policy options that could preserve existing nuclear power generation. The report finds that when they retire, nuclear reactors, which supply more than half of the country’s zero-emissions power, are being replaced by more carbon-intensive natural gas.
The report points to some operational and technological developments that might put nuclear plants on a firmer footing. First, electrification of other sectors of the economy could increase energy demand, easing pressure on larger and older energy plants like nuclear reactors. Second, midday nuclear power, which may not be needed when solar is available, could be stored as hydrogen and then used as fuel or feedstock. And third, nuclear plants that are paired with renewables could ramp up and down, following demand.
With federal policy to drive nuclear development in the near term unlikely, the report concludes that any long-term decarbonization strategy for the United States would entail policy support for both advanced nuclear and renewables.
“The nut we really want to crack is how renewables and nuclear can work together for each other’s mutual benefit,” tweeted report author Doug Vine, a C2ES senior energy fellow. “We need to have 80% reductions by 2050. We’re not going to get there if renewables and nuclear are fighting each other.”
To preserve the emissions benefits of nuclear energy, the report includes in its policy solutions
state-level policies such as expansion of state electricity portfolio standards to allow nuclear and renewables to work together on a level playing field to one another’s benefit as well as zero-emission credits, already being implemented in some states, to support distressed facilities. Other solutions offered by the report are license renewals by the U.S. Nuclear Regulatory Commission that would allow reactors to operate for 80 years; a “meaningful” price on carbon implemented in power markets; and increased pursuit by government agencies, cities and businesses of power purchase agreements, which give both buyers and sellers some certainty over a specified time period, for nuclear power.
DOE Plan Lays out Steps to Protect Grid from Cyber Threats
A new U.S. Department of Energy plan lays out steps to do more to protect the country’s energy systems and diminish energy interruptions due to the increasing scale, frequency and sophistication of cyber attacks.
“Energy cybersecurity is a national priority that demands the next wave of advanced technologies to create more secure and resilient systems needed for America’s future prosperity, vitality, and energy independence,” said Secretary of Energy Rick Perry. “The need to strengthen efforts to protect our critical energy infrastructure is why I am standing up the Office of Cybersecurity, Energy Security, and Emergency Response (CESER). Through CESER and programs like CEDS, the Department can best pursue innovative cybersecurity solutions to the cyber threats facing our Nation.”
The five-year plan focuses on strengthening preparedness, coordinating responses, and developing the next generation of resilient energy systems in line with the creation of a cybersecurity office—announced earlier this year—to help carry out activities to protect the grid from attack.
The plan calls for research and development into equipment and technologies that would “make future systems and components cybersecurity-award and able to automatically prevent, detect, mitigate, and survive a cyber incident.”

For the first time in recorded history, Earth has sustained an atmospheric concentration of carbon dioxide in excess of 410 parts per million—a symbolic red line in the methodical upward march of greenhouse gas concentrations. The April Keeling Curve measurements at the Mauna Loa Observatory are 30 percent higher than the first Keeling Curve measurements, 315 parts per million, at the observatory in 1958, and 46 percent higher than concentrations recorded during the Industrial Revolution in 1880. They are the highest in the 800,000 years for which scientists have good data, thanks to paleoclimate records like tree rings and ice cores.
Ralph Keeling, director of the CO2 Program at the Scripps Institution of Oceanography, which monitors the readings and calculates the one-month averages, said the rate of carbon dioxide concentration in the atmosphere has been increasing faster in the last decade than in the 2000s.
“It’s another milestone in the upward increase in CO2 over time,” said Keeling, who is also the son of Charles David Keeling, creator of the Keeling Curve. “It’s up closer to some targets we don’t really want to get to, like getting over 450 or 500 ppm. That’s pretty much dangerous territory.”
Last year the National Oceanic and Atmospheric Administration’s climate department reported that atmospheric carbon dioxide levels in 2016 were at levels not seen on Earth for millions of years, when temperatures were 3.6 to 5.4 degrees Fahrenheit warmer, and sea level was 50 to 80 feet higher than today.
Powelson Reflects on PJM Fuel Security Announcement, Defense Production Act
What are the primary drivers of change in the PJM Interconnection, which operates the electric grid for a 13-state region? Technology and people. That was the message from air and energy regulators from states in the PJM electricity market at an event co-sponsored by the Great Plains Institute and Duke University’s Nicholas Institute for Environmental Policy Solutions.
The event, keynoted by Robert Powelson of the Federal Energy Regulatory Commission (FERC), focused on change and the tensions revealed as different actors drive these changes or respond to their effects. Powelson reflected on PJM’s late April announcement that it will conduct a study to understand “fuel-supply risks in an environment trending towards greater reliance on natural gas.” PJM said it will conduct a three-phase analysis over several months to determine whether it can withstand a cyberattack on a natural gas delivery system or a prolonged cold snap.
Powelson cautioned that people should not read into PJM’s announcement that PJM may pay coal and nuclear generators to be backstops in the event of fuel delivery interruptions. “I think what PJM is saying is ‘we’re going to look at it and we’re going to do it in a market-based approach.’ There might be other technologies out there that have the same [fuel security] characteristics. It could be an oxidized fuel cell. It could be storage. It’s going to be a level playing field discussion. … It’s going to be done in a fuel-neutral, technology-neutral way.”
He called PJM’s capacity market proposal before FERC “a jump ball” aimed at neutralizing the effects of some state subsidies intended to prop up nuclear. PJM wants FERC to direct operators to update market compensation for power plants to reflect resilience attributes.
Powelson also touched on the U.S. Department of Energy plan to look into whether it can keep some struggling coal and nuclear plants operating by invoking the Defense Production Act—a 1950 law giving the president a broad range of power to require businesses to prioritize contracts for materials deemed vital to national security.
Invoking the act, Powelson said, “would lead to the unwinding of competitive markets in this country.”
Climate Talks Stall, U.N. Schedules Extra Sessions
As the latest round of Paris Agreement talks wind down May 10, delegates are marking their calendars for extra sessions to accomplish what they could not in Bonn, Germany, over the last two weeks: finalize the text of a rulebook for the agreement that aims to limit global warming to well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit that increase to 1.5 degrees Celsius. On Monday, Executive Secretary of U.N. Climate Change Patricia Espinosa said producing a rulebook was impossible at the current conference.
“A single negotiating text. No,” said Espinosa. “That would really not be possible. It will all come together when it comes to the level of the COP [Conference of the Parties], of the conference in December.”
Given insufficient progress in Bonn, U.N. officials announced on Tuesday that they were adding a week-long session in Bangkok in September in order to meet the deadline for a rulebook at the main summit in Katowice, Poland, in December. Without that document, negotiators would have no basis for those talks.
Several issues stalled the Bonn negotiations. Most developed countries want to know how much climate funding they are committing to developing countries, which contributed the least to climate change but suffer its worst effects. They also want to understand how that funding will be adjusted to support countries’ progressive emissions reductions every five years. There is also pushback from developed countries on funding for climate impacts to which developing countries can no longer adapt.
At the Talanoa Dialogue, an international storytelling side event aimed at increasing global ambition to reduce climate change, State Department climate negotiator Kim Carnahan described President Donald Trump’s vision of a “balanced” global energy landscape and said the administration’s “position on the Paris Agreement remains unchanged,” a reference to Trump’s decision to withdraw the United States from the Paris Agreement. She maintained that the United States would ensure the viability of its nuclear power sector, currently its largest single source of no-carbon energy. Carnahan also noted the power sector carbon reductions that have accompanied increased natural gas production from hydraulic fracturing.

Seventeen states and the District of Columbia filed a lawsuit Tuesday in the D.C. Circuit Court of Appeals over the U.S. Environmental Protection Agency’s (EPA) rollback of Obama-era vehicle emissions and fuel economy standards last month. In the lawsuit, those states and a few state offices write that the EPA “acted arbitrarily and capriciously” in overturning the previous administration’s decision.
“This is about health, it’s about life and death,” said California Gov. Jerry Brown. “I’m going to fight it with everything I can.” The EPA had no comment on pending litigation.
The corporate average fuel economy, or CAFE standards, were set to roughly double from 2010 levels to about 50 miles per gallon. In early April, the EPA Administrator Scott Pruitt announced plans to draft new standards for 2022–2025 with the National Highway Traffic Safety Administration. At that time Pruitt said that “Obama’s EPA … made assumptions about the standards that didn’t comport with reality, and set the standards too high.”
Obama-era rules for 2022 to 2025 sought to bring average fuel economy to 54.5 mpg, or 36 mpg in the real world.
The EPA and the National Highway Traffic Safety Administration are now in the final stages of drafting and could release new rules as soon as June. The Washington Post reports that the new rules could freeze fuel-efficiency standards for automobiles starting in 2021 and challenge California’s ability to set its own fuel-efficiency rules. Presently, California is authorized under the Clean Air Act to set its own fuel standards.
Paris Agreement Revisited in Bonn
“Urgency, ambition, opportunity” are the three words that must define 2018 said Executive Secretary of U.N. Climate Change Patricia Espinosa on Monday in Bonn, Germany, at the opening of the latest round of talks to advance the goals of the Paris Agreement, which seeks to limit global warming to well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit that increase to 1.5 degrees Celsius.
“By the end of 2018 we have the opportunity to accomplish three important goals,” Espinosa said. “Those are: building on the pre-2020 agenda, which charts the efforts of nations up to the official beginning of the Paris deal; “unleash[ing] the potential” of the Paris deal by completing the operating manual; and building more ambition into countries national pledges.”
The 2015 Paris Agreement, which comes into effect in 2020, left a number of critical rules and procedures to address before the U.N. climate conference in Katowice, Poland, in December. The Bonn talks, which conclude May 10, are aimed not only at creating a “rule book” but also at getting governments to increase the ambition of their current national plans for greenhouse gas emissions cuts.
According to the latest UN Environment Programme emissions gap report, released November 2017, current commitments would allow warming to increase to dangerous levels above 3 degrees Celsius. That conclusion prompted Fiji—the current holder of the U.N. Framework Convention on Climate Change presidency—to initiate at Bonn a sidelines process it calls the Talanoa Dialogue, referencing a Fijian tradition of storytelling to build empathy and collective decision making.
The process involves national negotiators meeting with academics, campaigners and lobbyists to exchange ideas. From more than 400 submissions for the discussions, some themes have emerged, among them, whether countries should aim to achieve the more ambitious of the Paris Agreements’ temperature goals—no more than 1.5 degrees Celsius of warming—as small island states have urged and whether the governments of richer nations will substantially increase their financial support to poorer countries for climate change adaptation.
One of the issues at stake this week and for the rest of 2018 is how countries will be asked to demonstrate that they’ve delivered on their emissions reduction commitments. The Paris Agreement gives some poorer countries accounting and reporting flexibility in light of their comparatively weak capacity to track and inventory their emissions and actions. But which countries receive that flexibility, how it’s implemented and for how long remain undecided.
PJM to Look at Fuel Security
The PJM Interconnection, which operates the electric grid for a 13-state region, says it will conduct a study to understand “fuel-supply risks in an environment trending towards greater reliance on natural gas.”
“We do not feel we have a vulnerability today, but will take a look at the system to see if we could have fuel security issues in the future,” said Andy Ott, president and CEO of PJM Interconnection. “We expect our analysis will result in a concrete set of criteria to value fuel security.”
PJM will conduct a three-phase analysis over the course of several months to determine whether it can withstand a cyberattack on a natural gas delivery system or a prolonged cold snap.
The issue is part of the “resiliency” question presently before the Federal Energy Regulatory Commission (FERC). Regional grid operators filed comments in March on efforts to enhance the resilience of the bulk power system in a proceeding initiated by FERC after it rejected a Notice of Proposed Rulemaking by U.S. Department of Energy Secretary Rick Perry to subsidize coal and nuclear power plants. The comments by the nation’s federally overseen regional transmission organizations and independent system operators came in response to two dozen questions FERC asked about resilience. At the heart of many comments was a question about how FERC defines resilience.
Two of my colleagues at Duke University’s Nicholas Institute for Environmental Policy Solutions made a similar query in a thought piece published in Utility Dive. Whether resilience is “a stand-alone concept or just a component of the well-recognized concept of reliability,” they said it is a “foundational question”—one that spells the difference between new market and regulatory responses or tweaks to existing reliability mechanisms.
