Nice and concise;
“If renewables sustain this rate of growth, the United States would be roughly on track to get all of its electricity from carbon-free sources by 2050. The question, of course, is whether that exponential growth can continue.” – Grist
The rise in solar and wind power is leading the US to generating enough renewable electricity that fossil fuels won’t be required. That doesn’t mean solar plus wind equals 100%. At least for the short term, renewables include nuclear and hydro.
US electricity in 2018
- Solar = 2.3%
- Wind = 6.5%
- Hydro = 6.9%
- Nuclear = 19%
The numbers are small now, compared to fossil fuels, but they’re growing so rapidly that IF the growth can be sustained THEN the US can dramatically reduce fossil fuel use and carbon dioxide pollution. The five-fold increase in about a decade is proof and evidence that positive changes can be made in short amounts of time – and we’re running out of time.
