    Wind Powering America Initiative: The Wind and Water Power Program (WWPP)

    Full text link
    The U.S. Department of Energy\u27s Wind Powering America initiative engages in technology market acceptance, barrier reduction, and technology deployment support activities. This fact sheet outlines ways in which the Wind Powering America team works to reduce barriers to appropriate wind energy deployment, primarily by focusing on six program areas: workforce development, communications and outreach, stakeholder analysis and resource assessment, wind technology technical support, wind power for Native Americans, and federal sector support and collaboration

    Presented to the Executive Board of ECREEE in April 2012The ECREEE Business Plan (2011 to 2016) provides a powerful strategic long-term framework which allows continued monitoring of the achievements of the Centre. By mapping out a clear vision, the plan serves to guide the Centre towards a position of relevance and sustainability in the coming years. The strategy includes the definition of objectives and milestones, performance indicators, activities, and human and financial resources requirements. It also highlights the peculiarities and specific challenges facing the region with respect to energy, while presenting the opportunities and barriers for renewable energy and energy efficiency deployment as well as a country-by-country review of the needs, opportunities and key issues within the sector

    Energy Efficiency: Efficiency or Monopsony?

    Get PDF
    The cliché in the electricity sector, the "cheapest power plant is the one we don’t build," seems to neglect the benefits of the energy that plant would generate. Those overall benefits could be countered by benefits to consumers if "not building that plant" was the result of monopsony. A regulator acting as a monopsonist may need to avoid rationing demand at monopsony prices. Subsidizing energy efficiency to reduce electricity demand at the margin can solve that problem, if energy efficiency and electricity use are substitutes. We may not observe these effects if the regulator can set price as well as quantity, lacks buyer-side market power, or is legally precluded from denying generators a reasonable return on capital. Nevertheless, the possibility of monopsony remains significant in light of the debate as to whether antitrust enforcement should maximize consumer welfare or total welfare.energy efficiency, monopsony, consumer welfare, total welfare, electricity

    Jobs from Renewable Energy and Energy Efficiency

    Get PDF
    According to research by Roger Bezdek for the American Solar Energy Society (ASES), the renewable energy (RE) and energy efficiency (EE) industries created a total of 8.5 million jobs (direct and indirect) in 2006; 450,000 jobs in RE and 8 million jobs in EE throughout the United States. As many as 1 out of 4 workers in the United States will be working in RE or EE industries by 2030. The 40 million jobs are not just engineering?related, but also include millions of new jobs in manufacturing, construction, accounting, and management.  

    Energy-efficiency for MISO-OFDMA based user-relay assisted cellular networks

    The concept of improving energy-efficiency (EE) without sacrificing the service quality has become important nowadays. The combination of orthogonal frequency-division multiple-access (OFDMA) multi-antenna transmission technology and relaying is one of the key technologies to deliver the promise of reliable and high-data-rate coverage in the most cost-effective manner. In this paper, EE is studied for the downlink multiple-input single-output (MISO)-OFDMA based user-relay assisted cellular networks. EE maximization is formulated for decode and forward (DF) relaying scheme with the consideration of both transmit and circuit power consumption as well as the data rate requirements for the mobile users. The quality of-service (QoS)-constrained EE maximization, which is defined for multi-carrier, multi-user, multi-relay and multi-antenna networks, is a non-convex and combinatorial problem so it is hard to tackle. To solve this difficult problem, a radio resource management (RRM) algorithm that solves the subcarrier allocation, mode selection and power allocation separately is proposed. The efficiency of the proposed algorithm is demonstrated by numerical results for different system parameter

    Introducing Energy Efficiency into SQALE

    Get PDF
    Energy Efficiency is becoming a key factor in software development, given the sharp growth of IT systems and their impact on worldwide energy consumption. We do believe that a quality process infrastructure should be able to consider the Energy Efficiency of a system since its early development: for this reason we propose to introduce Energy Efficiency into the existing quality models. We selected the SQALE model and we tailored it inserting Energy Efficiency as a sub-characteristic of efficiency. We also propose a set of six source code specific requirements for the Java language starting from guidelines currently suggested in the literature. We experienced two major challenges: the identification of measurable, automatically detectable requirements, and the lack of empirical validation on the guidelines currently present in the literature and in the industrial state of the practice as well. We describe an experiment plan to validate the six requirements and evaluate the impact of their violation on Energy Efficiency, which has been partially proved by preliminary results on C code. Having Energy Efficiency in a quality model and well verified code requirements to measure it, will enable a quality process that precisely assesses and monitors the impact of software on energy consumptio
