An optimistic – but realistic and feasible – action plan for fighting climate change while creating new jobs and a healthier electrify everything. Climate change is a planetary emergency. We have to do something now – but what? Australian visionary Saul Griffith has a plan. In The Big Switch, Griffith lays out a detailed blueprint – optimistic but feasible – for fighting climate change while creating millions of new jobs and a healthier environment. Griffith explains exactly what it would take to transform our infrastructure, update our grid, and adapt our households. Billionaires may contemplate escaping our worn-out planet on a private rocket ship to Mars, but the rest of us, Griffith says, will stay and fight for the future. ‘I’m a scientist, engineer, inventor and father who wants to leave my kids a better world. The data convinces me that it is still rational to have hope.’—Saul Griffith
