In August 2018, the U.S. Environmental Protection Agency (EPA) and National Highway Traffic Safety Administration (NHTSA) proposed a rule to roll back the requirements for automobile fuel economy standards. While existing standards are set to increase throughout model years 2017 to 2026, the proposed rollback would hold the standards constant at 2020 levels for model years 2021 through 2026. Synapse recently completed a report for Consumers Union and a second report with Consumer Reports related to the U.S. EPA’s and NHTSA’s proposed rollback.

On January 17, 2019, Brown University announced it would be converting a Rhode Island gravel pit into a 250 acre, 50 megawatt (MW) solar facility. This project is expected to offset 70 percent of the university’s electric load. To address Brown’s remaining supply needs, the university plans to enter into a power purchase agreement (PPA) with an 8 MW wind facility in Texas.

A new study from the Massachusetts Commission on the Future of Transportation in the Commonwealth argues for a bold public policy to counter the challenges of climate change and inequality over the coming two decades. Titled “Choices for Stewardship,” the report calls policymakers, municipalities, and industry to action with a broad agenda of 18 recommendations for modernizing the state’s transportation sector.

The October 2018 Intergovernmental Panel on Climate Change (IPCC) special report on climate change highlights the importance of averting catastrophic climate change. Centrally, it finds that global carbon dioxide (CO₂) emissions must reach net zero by 2050 in order to limit global warming to 1.5°C. With the United States’ announced withdrawal from the 2015 Paris Climate Accord, the future of its commitment to reduce emissions 80 percent from 1990 levels is in peril.

Today’s electric system is almost unrecognizable from the electric system a decade ago. Generation from natural gas and renewables has accelerated to replace the rapid and unprecedented retirement of coal-fired generators. Wind, solar, and geothermal electric generating capacity in the United States has now eclipsed capacities from hydroelectric and nuclear resources combined.

On February 6, 2018, the U.S. Energy Information Administration (EIA) released the 2018 Annual Energy Outlook (AEO). The final AEO 2018 contains projections of energy use from the electric power, residential, commercial, industrial, and transportation sectors through 2050. It is important to note that the AEO Reference case is not a forecast, but is instead a projection based on estimates of fuel availability, changes in technology costs, and currently enacted legislation.

The Northeast is going to have to step it up if states want to meet their admirably ambitious goals to reduce greenhouse gas (GHG) emissions to roughly 80 percent below 2001 levels by 2050. While the seven states in question—Connecticut, Maine, Massachusetts, New Hampshire, New York, Rhode Island, and Vermont—had by 2015 managed to get their GHG levels down by 19 percent, the approaches they’ve been using won’t be enough. Enter strategic electrification—an approach increasingly recognized as an essential and cost-effective part of deep decarbonization.

Economy-Wide Emissions Modeling for the Real World: Conventional electricity modeling done in isolation no longer cuts it in a world that is rapidly transitioning to a new energy future. As we increasingly electrify our transportation, building heating, and other energy end uses, substantial energy and emissions will be shifted to the electric sector.

In the wake of the U.S. Supreme Court’s surprising and controversial decision to stay implementation of the Clean Power Plan—which limits the emission of carbon dioxide from existing power plants—here’s a bit of global context (see figure below).
