The U.S. electricity market, like electricity markets in most countries, is heavily dependent on fossil-fuel generation from centralized power applications. This paper reviews the factors that led to the sector??s reliance on fossil fuels and presents a future vision of the U.S. electricity sector based on a varied spectrum of sustainable energy resources ranging in scale from large, centralized facilities to small, localized energy systems. This spectrum includes low-emissions energy and energy efficiency, as well as macro-generation, micro-grids, distributed generation, micro-generation and end-user conservation. We discuss the evidence that each element of this spectrum is a viable and proven technology, the balanced integration of which could shape an electricity sector that adheres to sustainability principles. This paper concludes with a discussion of the institutional barriers that need to be addressed to successfully achieve a transition toward a more future sustainable electricity sector based on the variations in scale. 相似文献

The first part of this two part essay is a re-examination of the Czechoslovak crisis (1934–1938) based on papers from the Arkhiv vneshnei politiki Rossiiskoi Federatsii in Moscow. The essay is also grounded in British, French, and Romanian archives and the standard published collections, including the American and German series. It is about the development and conduct of Soviet collective security policy in the key years leading to the “Munich crisis” in September 1938. Evidence from the Moscow archives demonstrates that the Soviet government was serious about collective security and that it was ready to participate in an anti-Nazi alliance. Its initiatives were repeatedly rebuffed in Europe, notably in Paris and London. Even in Prague, the Czechoslovak president, Eduard Bene?, was an undependable ally. These rebuffs led the Soviet government to be cautious during the Munich crisis. The Soviet Union would not act unilaterally, but what it actually did do was intended to defend Czechoslovak security within the constraints of Anglo–French abandonment in which Bene?? himself was complicit. 相似文献
