This is one of a series of reports produced as a result of the Transportation Energy Futures (TEF) project, a U.S. Department of Energy (DOE)-sponsored multi-agency project initiated to identify underexplored strategies for abating greenhouse gases and reducing petroleum dependence related to transportation. The project was designed to consolidate existing transportation energy knowledge, advance analytic capacity-building, and uncover opportunities for sound strategic action.
The Transportation Energy Futures (TEF) Study evaluates various technological, fuel substitution, and policy options for reducing transportation-related greenhouse gas (GHG) emissions and petroleum use. In 2009, 30 quadrillion Btu of energy were used in the transportation sector. …
View Full ResourceIn 2009–2011, a comprehensive project on urban buses was carried out in coop- eration with IEA’s Implementing Agreements on Alternative Motor Fuels and Bio- energy, with input from additional IEA Implementing Agreements. The objective of the project was to generate unbiased and solid data for use by policy- and deci- sion-makers responsible for public transport using buses. The project comprised four major parts: (1) a well-to-tank (WTT) assessment of alternative fuel pathways, (2) an assessment of bus end-use (tank-to-wheel, TTW) performance, (3) combin- ing WTT and TTW data into well-to-wheel (WTW) data and (4) a cost assessment, including indirect as …
View Full ResourceWe develop estimates of future spending and savings for energy efficiency programs funded by electric and gas utility customers for three scenarios that capture a range of state policy and program spending paths through 2025. Our analysis relies on a detailed bottom-up modeling approach of state energy efficiency policies, regulatory decisions, and utility resource and demand-side management plans. Spending on efficiency programs is projected to more than double from 2010 levels to $10.8 billion in 2025 in the medium scenario, which is premised largely on compliance with existing energy efficiency policies, and would more than triple to $16.8 billion in …
View Full ResourceImproving appliance energy efficiency standards will benefit consumers, manufacturers, and the environment. Consumers will save money on their electric bills and likely enjoy updated appliances at a lower cost as a result of improved standards. Manufacturers stand to gain from increased sales and lowered production costs. The environment will benefit from reduced natural resource consumption and lowered greenhouse gas emissions. Unfortunately, these benefits are not currently realized due to numerous delays at both the political and federal agency levels. These delays will result in at least $28 billion in unrealized energy savings by 2030.

View Full ResourceMuch of today’s energy policy assumes that regulations mandating greater energy efficiency will reduce energy use. That isn’t always the case and energy efficiency improvements are seldom as large as promised by engineering calculations because of “rebounds.” For example, people who install lighting that is 50 percent more efficient frequently leave the lights on longer, negating some of the energy savings from greater efficiency. This is called an energy efficiency rebound. Sometimes these mechanisms even bring about net increases in energy use known as “backfires.”
Rebounds have a direct implication for energy efficiency mandates and incentives. If rebounds are substantial, …
View Full ResourceThe paper provides a comprehensive review of a wide range of problems and inconsistencies in current cost-effectiveness test practices, and recommends a range of best practices to address them. These best practices (a) align test implementation with the underlying objectives of the tests as originally designed;(b) ensure that energy resources are developed at the lowest cost; and (c) support public policy goals such as promoting customer equity, serving a broad range of customers, encouraging comprehensive whole-house improvements, and avoiding lost opportunities.…
View Full ResourceA large share of total U.S. energy consumption—40 percent—occurs in homes and buildings. Homes and buildings are less energy efficient than they would be if people could assess the value of energy savings more easily and correctly, and if energy prices provided them with stronger incentives to do so. This paper identifies three reasons why people undervalue energy savings: misperceived energy prices, imperfect information about energy efficiency, and biased reasoning about energy savings. The paper then examines four types of policy options for addressing those underlying market imperfections: prices that reflect the social costs of energy use, financial incentives, energy-efficiency …
