Techno-optimists have hoped that technology would solve the climate crisis for us by delivering a renewable energy revolution. They regularly point to amazing technological advances in solar panels, wind turbines, advanced biofuels, hydropower and enhanced geothermal. If only. The ugly climate data from global energy experts like the IEA and the US Energy Information Agency's (EIA), however, shows this isn't happening. Today, renewable energy supplies the same small percent of the world's energy as it did a quarter century ago.
