Climate change is one of the great challenges of the 21st century. Its most severe impacts may still be avoided if efforts are made to transform
current energy systems. Renewable energy sources have a large potential to displace emissions of greenhouse gases from the combustion of
fossil fuels and thereby to mitigate climate change. If implemented properly, renewable energy sources can contribute to social and economic
development, to energy access, to a secure and sustainable energy supply, and to a reduction of negative impacts of energy provision on the
environment and human health.
This Special Report on Renewable Energy Sources and Climate Change Mitigation (SRREN) impartially assesses the scientifi c literature on the
potential role of renewable energy in the mitigation of climate change for policymakers, the private sector, academic researchers and civil society.
It covers six renewable energy sources – bioenergy, direct solar energy, geothermal energy, hydropower, ocean energy and wind energy – as well
as their integration into present and future energy systems. It considers the environmental and social consequences associated with the deployment
of these technologies, and presents strategies to overcome technical as well as non-technical obstacles to their application
