Control of Wind Turbines: Accomplishments and Continuing Challenges

submitted by: RASEIBoulder
Wind energy is recognized worldwide as cost-effective and environmentally friendly and is among the world's fastest-growing sources of electrical energy. Despite the amazing growth in global wind power installations in recent years, science and engineering challenges still exist. Megawatt wind turbines are large, flexible structures that operate in uncertain, time-varying wind and weather conditions and lend themselves nicely to advanced control solutions. Advanced controllers can help...

Photovoltaics Technology: No Longer an Outlier

submitted by: icamp2012school
Larry Kazmerski, National Renewable Energy Laboratory Solar energy from photovoltaic devices has been around since the early days of the space race, but historically has not had a substantial impact on our global energy scheme. Is that now changing? Dr. Larry Kazmerski is the executive director of Science & Technology Partnerships at the National Renewable Energy Laboratory (NREL) in Golden, CO. He has worked at NREL for over 30 years and was previously the director of the National...

The 21st Century Solar Army Center for Revolutionary Solar Photoconversion Seminar Series

submitted by: RASEIBoulder
Summary: The sun is a boundless source of clean energy, but it goes down every night. We and many others are trying to design solar-driven molecular machines that could be used on a global scale to store solar energy by splitting water into its elemental components, hydrogen and oxygen. Hydrogen is a clean fuel that could be used directly or combined with carbon dioxide to produce methanol, a liquid fuel. We are working on rugged light absorbers and catalysts made from Earth abundant...

Materials - The Technology Barrier to Advanced Batteries for Energy Storage

submitted by: RASEIBoulder
Summary: Energy storage is the enabling technology for renewable energy, such as wind and solar, and particularly for the next generation of hybrid electric vehicles, the plug-in hybrid electric vehicle (PHEV). If long-lived, low cost and safe batteries are to be developed, the materials limitations must be overcome. Intercalation is the predominant reaction mechanism in rechargeable batteries in use today. Intercalation processes, unlike conversion reactions, allow for fast ionic motion...

Change Is Inevitable, Except from a Vending Machine: The Dynamics of U.S. Energy Efficiency Politics and the Case of Residential Appliances

submitted by: RASEIBoulder
Summary: This talk looks at how energy politics change over time and the factors that influence how struggles over energy play out. I start out by building on two competing theories from environmental sociology that provide political economic explanations of environmental degradation and improvement: ecological modernization (EMT) and treadmill of production (TOP). Ecological modernization theory predicts that as capitalist nations develop the environment will improve. Treadmill of...

The Economics just aren't there: Towards a Model of Wind Energy Industry Development in Industrial and Emerging Economies

submitted by: RASEIBoulder
Summary: Through the development and analysis of in-depth case studies of the emergence of wind power industries in industrialized and emerging economies, a model of sustainable energy industry development is proposed. The model demonstrates that fundamental economic indicators are insufficient for explaining new industry development. Environmental, institutional and cultural factors idiosyncratic to individual jurisdictions play important roles in the emergence of renewable energy...
