The Impact of Natural Gas Prices on Electricity Consumers and the Environment

Coinciding with the recent increase in US natural gas production, the country has seen a 60 percent decrease in the price of natural gas. Lower natural gas prices have affected electricity prices and emissions rates differently across various regions. For example, during this time period, the Texas Reliability Entity experienced one of the largest decreases […]

EPA’s Clean Power Plan: Breaking Down the Building Blocks

In the graph below, we explore two important aspects of EPA’s Clean Power Plan. EPA’s state targets for CO2 emissions reductions for existing power plants are in terms of emissions rates—mass of CO2 emissions per unit of electricity generation (lb/MWh). An alternative way to measure emissions reductions (and what matters) is mass terms alone (lb […]

Energy Efficiency in 111(d): Evaluating Energy Savings for Carbon Reduction

EPA’s Clean Power Plan uses expanded energy efficiency programs as a component of states’ emissions rate targets. States that choose to use energy efficiency for compliance need to develop and provide EPA with a plan for evaluating energy savings that result from the policy. In the technical support document for state plans, EPA describes the […]

Energy Efficiency in 111(d): The Role of End-Use Efficiency in State Compliance Plans

In a prior blog post, I describe the contribution of energy efficiency to state emissions-reduction targets in EPA’s Clean Power Plan. As EPA has pointed out, including energy efficiency in states’ targets does not mean that states will necessarily choose to include energy efficiency programs in the compliance plans they submit to EPA. Many factors […]

Twitter Q&A Roundup: EPA’s Clean Air Plan

On June 5, RFF hosted a seminar titled, “Making Sense of EPA’s Proposed Rule for Reducing Greenhouse Gas Emissions from Power Plants.” We did not have time to answer all of the questions posed by our Twitter audience during that event due to time constraints. Below are our responses to some of those questions. #askRFF […]

Mixing and Matching Electricity Sector Policies

A number of concerns have emerged over the last decade about climate change, energy security, and energy efficiency, inspiring an equally long list of proposed policy fixes. The majority of these options, including renewables subsidies, performance standards, and emissions pricing schemes, apply directly to the power sector. Lawmakers can also choose to implement multiple policies […]

Flexibility and Cost-Effectiveness in Proposed Climate Policies

Achieving the goal of an 83 percent reduction in US carbon dioxide (CO2) emissionsfrom 2005 levels by 2050 will require the electricity sector—which accounts for roughly 40 percent of US CO2 emissions—to make an enormous pivot away from fossil fuels toward non-emitting sources. Policy will be required to achieve this goal. In a recent RFF […]

Preserving Flexibility

Decisions EPA is making today will have a major impact on the cost-effectiveness of its planned move to regulate carbon emissions from existing power plants. The agency has proposed and will soon finalize performance standards for new power plants. These new-source standards are a prerequisite for the planned existing-source standards, but are ostensibly otherwise unrelated […]

Who Benefits from Flexible GHG Rules?

US climate policy is unfolding under the Clean Air Act. Mobile source and construction permitting regulations are in place. The US Environmental Protection Agency (EPA) has developed draft final rules for the performance of new power plants. Most important, EPA and the states will soon determine the form and stringency of the regulations for existing […]

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 […]
