Energy Exchange

We’re wasting solar energy because the grid can’t handle it all. Here’s a solution.

caligrid_378x235California has a nice problem: It’s producing so much clean solar energy that the state’s electric grid is at capacity, and sometimes beyond.

As Vox’s David Roberts reports in his excellent piece about California’s grid headache, it makes good sense to expand the system by interconnecting state-run energy markets.

But he also notes, at the end of his story, some other and complementary strategies California can use to increase its grid bandwidth – while accommodating rapidly growing, but variable, renewable energy sources.

Connected grids, alone, are not a long-term fix. Read More »

Finding a United Front as Methane Becomes Key Climate Battle

By Mark Brownstein and Steven Hamburg

Washington Post science writer Chris Mooney weighs in today with a deep-dive on rising methane emissions from America’s surging natural gas production, calling it “most important mystery about U.S. climate change policy.” This story is just the latest to highlight the need to address this urgent climate threat. It follows Bill McKibben’s compelling piece in the Nation exploring the same question and suggesting methane has overwhelmed the benefits of carbon dioxide reductions.

McKibben raises a crucial question, one we’ve spent a lot of time looking at ourselves. He’s right that methane is one of the most pressing fronts in the fight against disastrous warming, and one of the many reasons we need to speed the transition to clean energy. But we are more hopeful than Bill is about prospects for effectively addressing the methane problem in the meantime.

Big Problem, Critical Opportunity

Oil and gas methane emissions are a huge threat. But the very same properties that make methane such a danger to the climate also mean it’s an opportunity — a chance to reduce the rate of temperature increase in the next two decades while we simultaneously do the hard work of reducing CO2 emissions. Tackling methane is the single most impactful move we can make to alter the trajectory of climate change we experience now, even as we continue to accelerate the shift to low- and zero-carbon energy.

It Ain’t Over ’til It’s Over: Ohio Bailout Battle Marches On

case-law-pixabayIn extremely disappointing news, the Public Utilities Commission of Ohio (PUCO) recently approved the AEP and FirstEnergy bailout cases. By keeping old, uneconomic coal and nuclear plants running for the next eight years, the bailouts are bad for customers, bad for the environment, and bad for the competitive electric market. Even worse, customers are forced to subsidize these plants, even if they buy their power from a different supplier.

A broad coalition of consumer, industrial, commercial, and environmental advocates opposed the bailouts, but the PUCO disregarded this strong public opposition. However, the battle over the bailouts is far from over.  Read More »

Transforming the Electric System to Reduce Costs and Pollution

electrical-power-linesBy: Beia Spiller and Kristina Mohlin

Electricity markets around the world are transforming from a model where electricity flows one way (from electricity-generating power plants to the customer) to one where customers actively participate as providers of electric services. But to speed this transformation and maximize its environmental and cost benefits, we need to understand how customer actions affect the three distinct parts of our electric system: generation, transmission, and distribution.

Ohio Gov. Kasich Moves to Reduce Environmental Impact of Natural Gas Industry

The administration of Ohio Governor John Kasich announced today that the Ohio Environmental Protection Agency (OEPA) is taking another important step to reduce harmful air pollution from natural gas operations.

This isn’t the first time the Kasich administration has moved to address air pollution from the oil and gas industry. In 2014 Ohio joined Colorado and Wyoming in requiring operators to conduct quarterly inspections at well sites to find and fix emissions from leaking equipment. Today’s action extends these requirements upstream, and – notably — proposes to regulate both VOCs and methane, a move that helps cement Ohio’s position as one of the leading states on this issue.

Comprehensive methane rules are also under development in Pennsylvania (the nation’s second largest gas producer) and California (the nation’s third largest oil producer). Under both Republican and Democratic leadership, each of these states has recognized the benefits of keeping harmful emissions out of the air and valuable product in the pipeline. At the same time, they’re proving that these policies are highly cost-effective to implement. Read More »

A Successful Cleanup at Aliso Canyon Requires a Principled Approach

aliso pic 2The leak in Southern California Gas Company’s Aliso Canyon Facility released a massive amount of methane – a powerful climate change pollutant. Like other catastrophes, now that the pollution release is stemmed, the focus shifts towards cleanup and mitigation (as well as establishing causation, preventing recurrence, and pursuing legal actions).

Last week California took a major step on the cleanup front with the release of the final Aliso Canyon mitigation plan, a plan to cut pollution equal to about 100,000 metric tons of methane. Its aims to achieve these reductions by focusing on the agriculture and waste sectors, increasing energy efficiency and decreasing use of fossil fuels, and reducing methane “hot spots.”

While the portfolio of strategies laid out within the finalized plan is strong, this is only the beginning of a lengthy process, and one in which pushback from SoCalGas is already palpable. As the critical details of the mitigation plan are put into action, adherence to core principles is necessary to ensure mitigation from the Aliso Canyon disaster is a success story for the climate and people of California.
