"The good news is it's now clearly cheaper to save the planet than to ruin it," says engineer and investor John Doerr. "The bad news is: we are fast running out of time." In this conversation with climate policy expert Hal Harvey, the two sustainability leaders discuss why humanity has to act globally, at speed and at scale, to meet the staggering challenge of decarbonizing the global economy (which has only ever increased emissions throughout history) -- and share helpful examples of promising energy solutions from around the world.

John Doerr and Hal Harvey: How to decarbonize the grid and electrify everything

How to decarbonize the grid and electrify everything

Decarbonizing the grid and electrifying everything could transform our carbon footprint, with solar and wind leading the charge.

Innovative policies like continuous improvement in building codes have quietly revolutionized energy efficiency over decades.

Understanding the decision-makers in energy policy is crucial; just 250 people control 40% of the US's carbon emissions.
