China is massively building solar, wind, hydro, and nuclear, and also has by far the largest network of UHV transmission lines (and are building many more) so that they can get electricity from the regions with the most solar and wind to the more northern heavy industrial areas. They are also the leader in producing and exporting solar and wind equipment, and in driving the prices down, to make it easier for other countries to address climate change. They are also the biggest producer of EVs in the world, and the biggest exporter of EVs. They are doing better at doing something about climate change than any other country, both due to what they are currently doing for themselves and for the countries they export to and in their ability to make long term plans and reasonably stick to them.
