Few people doubt the threat of climate change and the urgent need to conquer fossil fuel addiction. But can renewable sources of energy ever be sufficient to provide modern societies with a decent quality of life? This book is clear they can, covering all the latest technologies and a roadmap to powering the world, not just sustainably, but democratically. Part of a four-title relaunch of the NoNonsense series with new cover designs, layout and logo. The arguments over the science of climate change have (largely!) been won so now is the time to influence the discussion about the technology, economics and politics of the transition to a low-carbon world, and particularly in the runup to the Paris climate talks in December 2015. A key question this book addresses is how do we power the world not just sustainably but democratically. This angle hasn't been explored and is key to the climate justice debate. As divestment in fossil fuels is becoming a reality how can investment in renewables be managed. There is an opportunity for energy to be more fairly generated, managed, distributed and funded. It also includes probably the most comprehensive and up-to-date introduction to the technology for non-technical readers.
