The next few decades will see a profound energy transformation throughout the world. By the end of the century, we will shift from fossil fuel dependence to reply primarily on renewable sources like solar, wind biomass, and geothermal power. Driven by the need to avert catastrophic climate change and by the depletion of easily-accessible oil, coal, and natural gas, this transformation will entail a major shift in how we live. What might a 100% renewable future look like? Which technologies will play a critical role in our energy future? What challenges will we face in this transition? And how we can make sure our new system is just and equitable? In Our Renewable Future, expert Richard Heinberg and scientist David Frindley explore the challenges and opportunities presented by the shift to renewable energy. Beginning with a comprehensive overview of our current energy system, the author's survey issues of energy supply and demand in key components of society, including electricity generation, transportation, housing and manufacturing. In their detailed review of each sector, the authors examine the most crucial challenges we face, from intermittency in fuel sources to energy storage and grid redesign. The book concludes with a discussion of energy and equity and a summary of key lessons and steps forward at the individual, community, and national level. The transition to clean energy will not be a simple matter of replacing coal with wind power of oil with solar; it will require society to adapt our energy usage as dramatically as we adapt our energy sources. Our Renewable Future is a clear eyed and urgent guide to this transformation that will be a crucial resource for policymakers and energy activists. The Authors - Richard Heiberg is a Senior Fellow of the Post Carbon Institute and is widely regarded as one of the world's foremost educators about the need to transition away from fossil fuels. He has authored twelve books, including The party's Over: Oil, War, and the Fate of Industrial Societies and After burn: Society Beyond Fossil Fuels, and scores of essays and articles that have appeared in such journals as Nature, The American Prospect, The pacific standard, Public Policy Research, Quarterly Review, The Ecologist, Resurgence, The Futurist, European Business Review, Earth Island Journal and The Sun. David Fridley has been staff scientists at the Energy Analysis Program at the Lawrence Berkeley National Laboratory in California since 1995. He is also Dubiety Group Leader of Lawrence Berkeley's China Energy Group, which collaborates with China on end-user energy efficiency, government energy management programmes and energy policy research. Fridley has written and spoken extensively on the energy and ecological limits of biofuels and serves as Renewable Energy & Energy Efficiency Fellow at Post Carbon Institute.
