From prehistory until the Industrial Revolution, most energy sources used by humans were localized (i.e., available within 5–10 miles of end users). Energy sources included draft animals, human slaves, and renewable sources such as biomass (wood and wastes), water mills, and wind power. Following the onset of the Industrial Revolution, with advancements in transportation technology and increased rates of deforestation in many regions, societies increasingly relied on long-distance shipments of coal, wood, and eventually oil, natural gas, and electric power.

In Europe, modern renewable energy sources technologies were explored thoroughly for the first time after the oil embargo/ price crisis of 1973. Notably, market introduction of renewable energy technology started in about 1985, but the renewable energy sources industry has become vital only during the past decade. Accordingly, relevant statistical renewable energy sources data have been systematically compiled only over the past decade, although reliable and consistent statistical renewable energy sources data, collected since 1989, exist for all 15 countries of the European Union and for Western Europe (defined here as the EU-15 plus Switzerland, Norway, and Iceland).

Nuclear energy has some distinct advantages in strengthening the external dimension of energy supply security. These include:
• Nuclear power plants produce electricity domestically. Their capital and labor inputs are also provided domestically. With more than 90% of its inputs in terms of value sourced domestically, it can be considered a largely domestic source of energy and electricity.
• Of course, a majority of OECD countries import part or all of their requirements of uranium plutonium. (more…)

The aim is to work with cities in advancing renewable energy technologies and systems and to help promote the renewable energy industry in a way that allows it to serve as model for the rest of the national urban system. The emphasis is therefore on market-led approaches of technology system development and deployment, through pricing, investment, electricity purchasing policies, information, model action, and other means.

Foundations have made good progress on the energy front, but huge gaps remain. Promising technologies in energy production and use today prove that the prospects for an affluent but low-carbon society are good. But the U.S. and the world economies continue to run primarily on oil and coal. As the largest consumer and producer of energy in the world, the United States has the responsibility to lead the transition to cleaner energy technologies. (more…)

Energy efficiency is defined here to mean energy services provided per unit of energy input (for example, gallons of water heated to a specified temperature per British thermal units of natural gas input). Within this framework, energy efficiency is conceived primarily at the disaggregated, product level, rather than at a more aggregated sectoral level. (more…)
