What Do State Renewable Portfolio Standards Mean for Carbon Intensity?

In the last two decades, 31 states have passed renewable portfolio standards (RPS) into law that are aimed at increasing the portion of state energy that is sourced from renewable, typically non-carbon-emitting, resources. In many states, such standards were not explicitly meant to reduce greenhouse gas (GHG) emissions, although given the energy sources they promote […]

Twitter Q&A Roundup: Exploring the Local Impacts of Shale Gas Development

On April 10, RFF hosted a seminar on the benefits and costs of shale gas development as experienced by local communities, titled “Exploring the Local Impacts of Shale Gas Development.” As moderator of that event, I’ll attempt to tackle some of the questions posed by our Twitter audience during the event that we were unable […]

Identifying “Known Unknowns” in the Natural Gas Revolution

Last week, my colleagues and I released a new RFF report, The Natural Gas Revolution: Critical Questions for a Sustainable Energy Future. At one point, I began referring to this document as the “Known Unknowns” report, in reference to a widely quoted Donald Rumsfeld speech. As the former secretary of defense noted, there are certain […]

Update on Ending the Export Ban: What It Means for US Gasoline Prices

Data aficionados among our readers will appreciate that it is best to analyze price movements using as disaggregated data as possible, both temporally and spatially. In the original version of our recent issue brief, we used annual data.  But with more time to acquire data, we found monthly data series.  Importantly, these new data include […]

Russia and Ukraine: The Energy Dimension

Russian incursion into Crimea, potential counter-measures by the United States and other Western countries, and retaliatory Russian responses to such counter-measures have, unsurprisingly, spotlighted the role of energy in the conflict. In the case of oil, Russia, it is accurately noted, is the world’s largest producer and second ranking exporter (behind Saudi Arabia). In the case […]

Misplaced Obsessions

The environmental movement has long been and will remain a crucial engine behind environmental policy, but I believe it really needs to reorient itself toward policies that matter, and in the process give up on its misplaced obsessions. First, environmentalists’ obsession with reducing carbon emissions is NOT misplaced. I am not just worried, but scared […]

Using Natural Gas to Lower Fuel Costs

With low-cost, abundant natural gas now available in the United States and the promise of new fuel and vehicle technologies on the rise, an opportunity may soon exist for industry (and consumers) to expand the use of natural gas in the form of a liquid fuel for passenger cars and trucks. In new research, RFF’s […]

Ending the Export Ban: What It Means for US Gasoline Prices

Last week, top Democrats on the Senate Energy and Natural Resources Committee requested a comprehensive review of what would happen—in terms of energy prices, consumer prices, and more—if the US were to lift its ban on oil exports. In a new RFF issue brief, together with Stephen Brown, Charles Mason, and Jan Mares, we tackle […]

Best of the Above

It looked like a reverse make-me-do-it  – President Obama in his State of the Union address saying don’t-do-that-again to some of his most committed supporters.  An array of groups had written to him just two weeks earlier about the failings of an “all of the above” energy policy, and the first words in his speech […]

How the Cold Snapped Clean Currents

Renewable power retailer Clean Currents will no longer provide electricity to its 15,000+ customers, as it had reliably done since 2005. Co-founders Gary Skulnik and Charlie Segerman announced on Friday that the company has shut its doors forever. Why? In a blog post to its customers, the duo explains that the recent severe cold weather […]
