A lot to say here, as this article touches on many subjects, let's dig in. First it is evident the focusing on carbon intensity is the most pragmatic & economic way to lower emissions period, proven by the United States. Nuclear is the other but outside the scope of this post. Secondly, renewables can only exist on a grid if flexibility complimentary system exist. Again America proves it. Denmark is also a case study given that they use their connection to the Nordic grid to balance out the large variability of their grid. We see what happens when this flexibility, e.i. natural gas or interconnected grid, is removed from the equation, we get Germany! Thirdly, growth of renewables does not and can not equal reduction in emissions. Chins has the greatest renewable capacity of any country-mostly talking about wind & solar as Norway & South America countries have more renewable on their grid a.k.a hydro-yet because of demand from manufacturing & population growth, coal continues to grow to fill demand. Lastly, we find that when push comes to shove countries show the iron law of electricity is hard to ignore. See the European & China energy crisis, when natural gas-a baseload resourse-was unavailable, King coal returned.
