We can’t admit defeat in push for renewable energy

As reported by the Globe, Daniel Yergin’s keynote address to the MIT Energy Conference exemplifies defeatism (“Fossil fuels at the forefront,” Business, Feb. 22). In predicting that, 20 years from now, renewables will remain “a relatively small part of the overall mix,” Yergin assumes that the future will follow a past in which we have remained passive even as our collective emissions of greenhouse gases have destabilized the climate of the only planet we happen to possess.

We have just completed our 347th month in a row of global average temperatures above the 20th-century average, so a future that truly followed the past would make fossil fuels less a form of energy than a catalyst of destruction.
