World energy and climate policy: 2009 assessment
World Energy Council (WEC),  2009, 194 p.

WEC believes that relentless improvement of government energy policies and industry practices are needed, and that this can lead to a material advancement in their capabilities to effectively handle these energy transitions. To enable this rapid change, WEC has launched a comprehensive, multi-year Assessment of Energy and Climate Policy, facilitated by the WEC’s unique structure of almost one hundred worldwide national committees.

This report encapsulates assessment results across 88 countries. Identified are top division country performers in energy policy effectiveness, overall and by major objectives, and many examples of country best practices. Countries are grouped into clusters dependent on whether they are energy importers or exporters and the level of income per capita.

Five Alternatives that make more sense than offshore oil
Carnegie Endowment for International Peace (US), 2009, 32 p.

Foreign oil currently fuels 55 percent of all transportation in the United States. As it struggles to reduce its dependence on foreign oil, the United States will have to completely rethink its energy policies. Instead of replacing imported oil with domestic oil, extracted at high environmental costs from new rigs offshore and across the western states, the country could opt for cleaner alternatives like higher fuel economy standards, hybrid-electric vehicles, plugin hybrids, cellulosic ethanol, and new commuting patterns. By decreasing demand rather than increasing supply, energy alternatives could reduce or eliminate the need to expand offshore oil production. This paper explores the economic and environmental costs of offshore oil and investigates a range of cleaner energy options.
