Concerns about energy security are growing, as highlighted by the recent political turmoil in Northern Africa and the nuclear incident in Fukushima. At the same time, the need to respond to climate change is more critical than ever. Against this background, many governments have increased efforts to promote deployment of renewable energy – low-carbon sources that can strengthen energy security. This has stimulated unprecedented rise in deployment, and renewables are now the fastest growing sector of the energy mix. This "coming of age" of renewable energy also brings challenges. Growth is focused on a few of the available technologies, and rapid deployment is confined to a relatively small number of countries. In more advanced markets, managing support costs and system integration of large shares of renewable energy in a time of economic weakness and budget austerity has sparked vigorous political debate.The  report :provides a comprehensive review and analysis of renewable energy policy and market trends;Analyses in detail the dynamics of deployment and provides best-practice policy principles for different stages of market maturity;Assesses the impact and cost-effectiveness of support policies using new methodological tools and indicators;Investigates the strategic reasons underpinning the pursuit of RE deployment by different countries and the prospects for globalisation of RE.--&#62; voir aussi : Renewable Energy: Policy Considerations for Deploying Renewables.

It provides more detailed data and analysis on policies for Deploying Renewables, and is intended to complement the main publication.It provides an account of the strategic drivers underpinning renewable energy (RE) technology deployment (energy security, economic development and environment protection) and assesses RE technologies with respect to these drivers, including an estimate of GHG emissions reductions due to RE technologies.The paper also explores the different barriers to deploying renewables at a given stage of market maturity and discusses what tools policy makers can avail of to succeed in removing deployment barriers.An additional topical highlight explores the challenges associated with accelerating the diffusion of RE technologies in developing countries.Renewable Energy: Markets and Prospects by Regions.

Paris : IEA, 2011, 66 p.http://www.iea.org/publications/free_new_Desc.asp?PUBS_ID=2475This information paper accompanies  Deploying Renewables 2011: Best and Future Policy Practice (IEA, 2011a). It provides more detailed data and analysis, and explores the markets, policies and prospects for a number of renewable energy technologies.This paper provides a discussion of ten technology areas: bioenergy for electricity and heat, biofuels, geothermal energy, hydro energy, ocean energy, solar energy (solar photovoltaics, concentrating solar power, and solar heating), and wind energy (onshore and offshore).Each technology discussion includes:the current technical and market statusthe current costs of energy production and cost trendsthe policy environmentthe potential and projections for the future andan analysis of the prospects and key hurdles to future expansion
