This Intergovernmental Panel on Climate Change Special Report (IPCC-SRREN) assesses the potential role of renewable energy in the mitigation of climate change. It covers the six most important renewable energy sources - bioenergy, solar, geothermal, hydropower, ocean 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 and diffusion. SRREN brings a broad spectrum of technology-specific experts together with scientists studying energy systems as a whole. Prepared following strict IPCC procedures, it presents an impartial assessment of the current state of knowledge: it is policy relevant but not policy prescriptive. SRREN is an invaluable assessment of the potential role of renewable energy for the mitigation of climate change for policymakers, the private sector, and academic researchers.

This study presents options to fully unlock the world’s vast solar PV potential over the period until 2050. It builds on IRENA’s global roadmap to scale up renewables and meet climate goals.

In Transforming California, Stephanie Pincetl argues that the transformation of nature in order to enhance economic development lies at the heart of much of the state's recent history. She sees late-twentieth-century California on a path of continued environmental degradation, gripped by cynicism about government. Transforming California describes the evolution of the state's institutions of government as they apply to land use and development, and it shows how land-use decisions affect people's quality of life and their daily interactions with each other and with their environment. Pincetl offers an alternative vision for the renewal of the democratic spirit and process in California and for a reconciliation with nature.
