How congestion pricing can help electrify the city’s bus fleet and improve air quality

By Rory Christian, New York Director, Clean Energy, Environmental Defense Fund, and Adriana Espinoza, New York City Program Director, New York League of Conservation Voters

Tons of ink has been spilled on the woes of the New York City subway system and the congestion pricing solution that would help fund its long-overdue improvements.

But congestion pricing can be much more than just a subway-fixing fund. It could also enable the electrification of the city’s entire bus fleet – a move that would save fuel costs, reduce the city’s carbon emissions and improve air quality for millions of New Yorkers that live, work and learn along the city’s maze of bus routes.

California’s move to cut utility gas leaks is a critical part of moving towards a low carbon future

As shown by the recent special report from the Intergovernmental Panel on Climate Change, emissions from fossil fuel combustion in California and elsewhere present dire consequences for the planet. This means California, like the rest of the world, must take real steps now to shift toward a low carbon future.

Similar to many other developed economies, California has a vast oil and gas delivery infrastructure that is integrated into its modern way of life – a system that supports the combustion of fossil fuels in nearly every corner of society. As a result, making dramatic shifts toward a carbon neutral economy as envisioned in a recent executive order by Governor Brown will take a lot of investment. While this investment is underway, it’s appropriate to also make sure the system that delivers energy to homes and businesses is as environmentally benign as possible.

Can blockchain unlock a sustainable future?

Blockchain – a really high-tech “spreadsheet” or ledger used to record transactions securely – offers exciting potential for clean energy. With the rapid rise of distributed energy technologies — such as rooftop solar, batteries, smart energy devices, and electric vehicles — some analysts believe the market for blockchain applications in the energy sector is many times larger than it is for cryptocurrency in the financial sector.

Blockchain technology may hold great promise for a sustainable future, but we need to solve some important challenges first.

Response to methane synthesis critiques

A new paper published in Science last week is the culmination of an extensive amount of research conducted over the past six years examining methane emissions from the U.S. oil and gas supply chain. The study finds that the U.S. oil and gas industry emits 13 million metric tons of methane per year – 60% higher than the EPA Greenhouse Gas Inventory (GHGI) estimates. Some industry sources have questioned the conclusions drawn in the paper and the methods employed to which I respond below.

The 25 co-authors of this Science paper represent 16 different research institutions. These experts were collectively responsible for generating most of the data analyzed and directly involved in writing the paper, which was subjected to a rigorous independent peer review as a condition of publication in one of the world’s top scientific journals.

Informed critiques are a valuable part of the scientific process. But the key issues raised by Energy in Depth (EID) and the American Gas Association seem to reflect a deep misunderstanding of the approaches used in the paper and the underlying data. Here, I explain the methods used to avoid bias and resolve differences among multiple data sets.

Resilience proceeding gives FERC a chance to advance gas-electric coordination

Last September, the U.S. Department of Energy (DOE) started a conversation on resilience, asking the Federal Energy Regulatory Commission (FERC) to provide new revenues and guaranteed profits to the owners of old, inefficient coal and nuclear power plants to compensate these resources for certain reliability and (undefined) resilience attributes.

FERC swiftly disposed of that proposal in a January 8 order, finding that it was not warranted and would run counter to its pro-market regulatory model. FERC then asked all of the Regional Transmission Operators (RTOs) and Independent System Operators (ISOs) to explain how they are evaluating and addressing resilience within their respective markets.

How location-based prices and utility rewards could help California’s electric grid

By Larissa Koehler, Jamie Fine

Distributed energy resources, from rooftop solar panels to smart well-weatherized homes and timed electric vehicle charging, are vital pieces of the clean energy puzzle. Coordinating how and where to encourage them in a way that benefits the electric grid, the environment, and Californians can be complicated. In its’ Integrated Distributed Energy Resource proceeding, the California Public Utilities Commission (Commission) recently asked stakeholders [PDF] to “consider how existing programs, incentives, and tariffs can be coordinated to maximize the locational benefits and minimize the costs of distributed energy resources.”

This key step forward in the proceeding is potentially a big deal. Why? Rocky Mountain Institute’s report puts it this way [PDF]:

“More granular pricing, capable of reflecting marginal costs and benefits more accurately than today’s rates do, will provide better incentives to direct distributed resource investments, regardless of whether investments in and management of [distributed energy resources] are undertaken by customers, by utilities, or by third-party service providers.”

By reflecting both costs and benefits in retail prices that electricity customers pay, California can modernize the grid while spurring the efficient and fair build out of distributed clean energy resources. This can help the state substitute traditional and inflexible polluting resources [PDF] with a variety of more nimble distributed energy resources where the grid can handle them. What’s more, distributed energy resources can lead to cleaner air in areas traditionally burdened by higher levels of harmful air pollution. They can achieve all this while bolstering the electric grid and protecting the health of the environment and of Californians. Read More »
