IAE estimates 50% of global electricity supplies from alternative resources by 2050
The International Energy Agency (IEA) estimates that nearly 50% of global electricity supplies will have to come from renewable energy sources if we want to halve CO2 emissions by 2050 in order to minimise significant and irreversible climate change impacts. This is a huge challenge and part of the entire energy revolution we need to achieve. Meeting these very ambitious objectives will require unprecedented political commitment and effective policy design and implementation. “Only a limited set of countries have implemented effective support policies for renewables and there is a large potential for improvement”, said Nobuo Tanaka, Executive Director of the IEA today in Berlin at the launch of the new study, Deploying Renewables: Principles for Effective Policies. “Several countries have made important progress in recent years in fostering renewables, with renewable energy markets expanding considerably as a result. However, much more can and should be done at the global level - in OECD member countries, large emerging economies and other countries - to address the urgent need of transforming our unsustainable energy present into a clean and secure energy future.” In this publication, the IEA has for the first time carried out a comparative analysis of the performance of the various renewables promotion policies around the world. The study encompasses 35 countries, including - all OECD members and the BRICS (Brazil, Russia, India, China and South Africa), and addresses the three relevant sectors electricity production, heating and transport.
In 2005, these 35 countries accounted for 80% of total global commercial renewable electricity generation, 77% of commercial renewable heating/cooling (excluding the use of traditional biomass) and 98% of renewable transport fuel production.
