China’s production of renewable energy is about 28% of domestic energy consumption. For India the number is 19%. For the U.S. about 20%.
Global the number is also about 28%.
The largest share of renewable energy production in both China and India is hydro. My understanding is that there isn’t much opportunity to significantly expand this production.
We needn't get into the technical here, China, much like the US, has plenty of room to grow their wind and solar industries, it's just challenging to move and store that energy. There is hope for that in hydrogen-based power plants, as hydrogen is a decent way to transport energy from one region to another. Those are being developed now.
The only reason why China was even brought up was as a reason for the US
not to pursue clean energy. Perhaps this is in good faith, but it is important to remember that discussions of electricity generation is a bit of a red herring, as the highest GHG emissions in the US comes from our automobile-based transportation system. It's also important to remember that this is an every-little-bit-counts scenario, so even if there were nations who flout climate goals (like the United States), it would be better if we transitioned away from them anyway.
The reason why this is even a discussion isn't because we are all trying to make it happen, and it's just challenging, it's that many-if-not-most people have decided they just don't care, and they've often given themselves an excuse to not care (like the fact that China can be challenging to work with).
At the end of the day, our historic links courses are rapidly falling into the ocean and will continue to. It's a bummer.
