Using Renewable Hybrid Power Systems to Meet Off-Grid Community and Commercial Energy Needs

submitted by: RASEIBoulder
Summary: Diesel generators are the traditional means by which people generate electricity in remote locations. Throughout the world, there are many thousands of off-grid communities, industrial sites, and government facilities relying entirely on diesel generated electricity. At $4/gallon, the fuel component alone of diesel-generated electricity is high, about $0.30/kWh. Some remote locations pay over $8/gallon or $0.60/kWh. With diesel fuel prices projected to rise even higher in the long...

Opportunities and Challenges of Offshore Wind Energy

submitted by: RASEIBoulder
Offshore wind power can contribute extensively to a clean, robust, and diversified U.S. energy portfolio. Capturing the Nation's large and inexhaustible offshore wind resource has the potential to mitigate climate change, improve the environment, increase energy security, and stimulate the U.S. economy. This seminar provides a broad understanding of the global offshore wind industry today and the associated technology challenges, economics, permitting procedures, and potential risks and...

Can Renewables Provide Big Energy in America's Electric Future?

submitted by: RASEIBoulder
Renewable energy sources currently provide about only about 10% of the nation’s electricity, with most of that coming from large hydro sources. Renewable energy sources are scattered around the country, with much of the best wind and solar resources located in remote locations. These sources also may have a big footprint compared to conventional sources. Finally, solar and wind are often described as intermittent due to their variable and uncertain output. As a consequence, it is often...

Addressing the Challenge of Truly Large Scale Photovoltaics

submitted by: RASEIBoulder
Addressing the Challenge of Truly Large Scale Photovoltaics: the Industrial and Thermodynamic Potentials of Organic Solar Cells In order for photovoltaic systems to ultimately provide a considerable fraction of the world’s energy needs they will need to meet a number of stringent performance metrics regarding their cost, efficiency, and robustness. In addition, they will need to be manufactured with very high throughput methods in order to realize the enormous production scales...

Re-evaluating The Hubbert Curve And The Global Petroleum Revolution: A New Era - Details

submitted by: RASEIBoulder
Summary: Why have the predicted global oil and natural gas shortages and demise of civilization by 2010 related to these vanishing supplies not occurred? The static view has created a pessimistic outlook based on historical perspective such as the Hubbert curve analysis which results in the inescapable and inevitable depletion that will result in catastrophic consequences for civilization. A new paradigm, a dynamic or petroleum system view demonstrates a different and more optimistic...

Economic Limits to Oil Supply: A Non-Hubbert Curve View

submitted by: RASEIBoulder
Authors: Richard S. Bishop and Wayne L. Kelley. Historically, questions of oil supply have been addressed by citing volumes of reserves and/ or resources. Supply, however, cannot be estimated from volumes alone but must include economic considerations. An optimistic outlook on global oil supply commonly will include large volumes of unconventional resources or undiscovered fields. While very large` such resources cannot add proportionately large supply rates due to logistical limitations,...
