We have an addiction to fossil fuels, and it's not sustainable. Howcan we replace fossil fuels? How can we ensure security of energysupply? How can we solve climate change?We're often told that "huge amounts of renewable power are available"- wind, wave, tide, and so forth. But our current power consumption isalso huge! To understand our sustainable energy crisis, we need toknow how the one "huge" compares with the other. We need numbers, notadjectives.This book shows how to estimate the numbers, and what those numbersdepend on. Taking the United Kingdom as an example, it asks first"could Britain live on renewable energy resources alone?" and second"how can a country like Britain make a realistic post-fossil-fuelenergy plan that adds up?" It answers these questions in detail,bringing home the size of the changes that society must undergo ifsustainable living is to be achieved. It's not going to be easy tomake an energy plan that adds up - but it is possible.A special feature of the book is that it avoids sensationalistnumbers. Where others deliberately use incomprehensibly large orsmall numbers to shock the reader, this book uses numbers andcomparisons to illuminate. For example, energy consumption andproduction are made accessible by expressing them in terms of theenergy used per person, per day.This book can also save you more than its cover price by helping youcut your energy bills!
