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 […]

Energy Efficiency in 111(d): Understanding Building Block #4

EPA’s recently released Clean Power Plan to regulate emissions of carbon dioxide (CO2) from existing power plants under the Clean Air Act includes four building blocks that are used to establish the target CO2 emissions rate for each state. Earlier blog posts by my RFF colleagues have described these different building blocks; my focus here […]

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 […]

Research Questions for the Midterm CAFE Review: The Fuel Efficiency Gap

This is the second in a series of blog posts by RFF’s transportation team that will address some of the key research questions for the midterm CAFE review. As the first post in this series described, US standards for passenger vehicle fuel economy and greenhouse gas emissions are slated to tighten steeply. By 2025, the […]

Research Questions for the Midterm CAFE Review

Our country is about to enter the most important period this decade for the future of transportation and its associated greenhouse gas (GHG) emissions. Fuel economy and GHG standards for both light-duty vehicles and heavier trucks are slated to tighten, reducing not only oil use but also GHG emissions. There is significant uncertainty about how […]

How Energy Efficiency Features are Reflected in Home Prices

In a recent analysis of real estate data from Portland, OR; Austin, TX; and the Research Triangle region of North Carolina, we find, with colleague Todd Gerarden, that local “green” certifications appear to have a larger impact on sales prices for homes than the national Energy Star certification. We also find that Energy Star certification […]

The New CAFE Standards: Are They Enough on Their Own?

The new CAFE standards may require complementary policies to meet the ambitious goals of reducing fuel consumption and greenhouse gas emissions. In a new RFF discussion paper, I examine the new footprint standards, their implications for changes to the size mix of vehicles, and the role of credit policies on compliance and cost-effectiveness of the […]

RFF Feature: Policy Insights for Narrowing the Energy Efficiency Gap

A new RFF discussion paper explores the “energy efficiency gap” and what it means for policy by bringing in the latest insights from behavioral economics. To read the full feature, click here.
