The Energy Transition: Powering a Post-Carbon World
Clean energy is now cheap—the hard part is everything else
Solar costs fell 90% in a decade. So why aren't we done?
Start here: make a prediction before reading
Solar and wind power costs have fallen over 90% in the past decade, making clean electricity cheaper than new coal or gas plants in most of the world. This price collapse was faster than almost any expert predicted.
The challenge has shifted from making clean energy affordable to building the systems that can deliver it reliably. Intermittent sources like solar and wind need grids, storage, and demand management that fossil fuels never required.
Energy choices made in the next decade will determine the climate trajectory for centuries.
