A Clean Energy Standard (CES) is a flexible, market-based policy instrument that could be adopted to reduce greenhouse gas emissions from the U.S. electricity system over time. This paper uses several well-known energy system and electricity models to analyze a CES that reflects broad principles...

This report examines the impact of renewable portfolio standards (RPS) and cap-and-trade policy options on the U.S. electricity sector. The analysis uses the National Renewable Energy Laboratory's Regional Energy Deployment System (ReEDS) model that simulates the least-cost expansion of...

Learning-i.e. the acquisition of new information that leads to changes in our assessment of uncertainty-plays a prominent role in the international climate policy debate. For example, the view that we should postpone actions until we know more continues to be influential. The latest work on...

One of the most striking things about forecasters is their lack of historical perspective. They rarely do retrospectives, even though looking back at past work can both illuminate the reasons for its success or failure, and improve the methodologies of current and future forecasts. One of the...

Recently, interest has grown in using monetary incentives as an efficient way to promote energy efficiency and environmental quality. This paper describes issues raised in designing revenue-neutral incentive policies to achieve these goals. Such policies involve charging fees in proportion to...

Comparison of nine conservation supply curves for electricity shows that fully implementing a series of energy efficiency measures will result in annual saving of 734 billion kWh (BkWh). This is 45 percent of 1989 U.S. building sector electricity use of 1627 BkWh and represents a $29 billion...
