About this report
Renewable sources of energy stand poised to lead the world in new electricity supply. Supported by policies aimed at enhancing energy security and sustainability, renewable power expanded at its fastest rate to date in 2014. Deployment has continued to shift towards energy-hungry emerging markets, and some countries, such as the People’s Republic of China and India, have bolstered ambitions. Moreover, sustained technology progress, expansion into newer markets with better resources, and improved financing conditions are facilitating more cost-effective deployment for the most dynamic technologies (solar photovoltaics and onshore wind). But will renewable growth in the coming years falter, or could an even faster expansion take place? The Medium-Term Renewable Energy Market Report 2015 assesses trends in the electricity, transport and heat sectors, identifying drivers and challenges to deployment, and making projections through 2020. It also assesses the potential impacts of enhanced policy actions under an accelerated case for renewable power, which would put the world more firmly on a path to a more sustainable and secure energy system.
