If we continue our highly inefficient, dangerous energy usage, we’re headed for both economic and environmental catastrophe. However, the hard truth is that alternative fuels can’t fully replace fossil fuels for decades. What’s more, new research indicates that energy inefficiencies are retarding economic growth even more than most experts ever realized.   Crossing the Energy Divide is about solving all these problems at once. The authors, two leading experts in energy and environmental economics, show how massive improvements in energy efficiency can bridge the global economy until clean renewables can fully replace fossil fuels.   Robert and Edward Ayres demonstrate how we can radically reform the way we manage our existing energy systems to double the amount of “energy service” we get from every drop of fossil fuel we use.   These techniques require no scientific breakthroughs: Many companies and institutions are applying them right now, but tens of thousands more could. This book offers a strategic guide for using them to solve the energy crisis once and for all—reducing carbon emissions, achieving true energy security, and reigniting economic growth for decades to come.   More energy, without more emissions Recapturing lost energy from today’s fossil fuels   There is such a thing as a free lunch Mitigating climate disaster and improving prosperity at the same time   The future of electricity Reforming tomorrow’s electrical system: smarter, more productive, and more reliable   The implications for cities, transportation, business, and government Making the decisions that prepare you for a high-cost energy future
