Great…
Except Steel, Concrete, Plastics, and Ammonia production all require fossil fuels and we do not have any alternative.
We also do not have a viable alternative for air travel, or large scale shipping.
While I think it is a worthwhile goal to pursue clean energy technologies, we are a very long way (with no known alternative) from getting rid of fossil fuels.
- natch 4y agoWe aren't getting rid of fossil fuels though, so this concern is a distraction from the real work that needs to be done. Yes of course we will still need fossil fuels even after we finish transitioning to renewables, for some of the cases you mention, and for edge cases. It's a valid point for you to raise since they made the mistake of making their article about renewable energy, not about the larger encompassing solution of which renewables are only a part, namely sustainable energy. But raising this point doesn't begin to dismiss the fact that a huge component of transitioning to sustainable will be transitioning much of our energy sourcing to renewables.
