Energy Technology Perspectives 2015 , published by the International Energy Agency, “ provides a comprehensive analysis of long-term trends in the energy sector, centred on the technologies and the level of deployment needed”….. “Wind and solar PV have the potential to provide 22% of annual electricity sector emissions reduction in 2050 under the 2DS” (2 degree scenario). The report is accompanied by Tracking Clean Energy Progress 2015, which finds that “ the deployment rate of most clean energy technologies is no longer on track to meet 2DS targets”. ….. “Policy certainty, incentives, regulation and international co-operation are required to meet stated ambitions and transform the global energy system”.
In the U.S., the U.S. Department of Energy released Enabling Wind Power Nationwide , which supports the U.S. ambition to expand utility-scale wind energy to all fifty states. The Enabling report highlights the the need for technological advancements, especially taller wind turbine towers and larger rotors, currently under development by the Energy Department and its partnering national labs, universities, and private-sector companies. The DOE Wind Program website is available here . A similar focus on the need for research and technological advancement is found in The Future of Solar Energy report , released by the Massachusetts Institute of Technology Energy Initiative (MITEI) .
