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 gener
