How Germany outfitted half a million balconies with solar panels

The country’s residents installed 200MW of balcony solar during the first half of 2024. It’s becoming an increasingly popular way to take climate action…

I always suspected this could be the case, and new research proves it's true: Rich countries could raise 5x the money poor countries need for climate finance thru windfall taxes on fossil fuels, ending harmful subsidies + a wealth tax on billionaires. Read more: www.oilchange.org/publications...

Rich countries could raise $5tn of climate finance a year, study says

Simple measures could raise five times more money than poorer countries are asking for, research claims

So, while assuming all coal is burnt overestimates GHG impact by <10% in China and less in other countries with smaller chemicals industries, there are other GHG costs (CH4 from mines, particularly) that we didn't include. And our estimates are broadly in line with many other sources / 1 more

Which would imply at most a 7% - 10% tweak to the GHG damage costs. New processes might do better but are likely to be subsumed by oil-to-chemicals processes. www.sciencedirect.com/science/arti...

A highly efficient and environmentally friendly approach for in-situ utilization of CO2 from coal to ethylene glycol plant

The development of carbon neutrality technology for the coal-based chemical industry is of great interest to many coal-rich countries. An improved coa…

but coal to ethylene glycol process emits 2–3 T CO2 per T of ethylene glycol, but I don't see clear data on how this computes to T CO2 / T coal. We can assume that the chemical production processes in China, burning 15% - 20% of the nation's coal, is producing at least 1/2 that % of GHG / more

In addition, which we did not count, coal mines produce CH4 emissions. 2. The world's largest coal consumer is China. There, it seems, ~15% (could be higher) goes to chemicals, mostly feedstocks like ethylene glycol. There are no useful data on the GHG emissions from these / more

Question has a complicated, essay-length answer, but ... 1. >91% of coal in the US goes to power gen. The remainder goes to steel production or chemicals. These ALSO produce GHGs. The US inventory of GHG emissions puts them at about 8% of the coal-for-power total. / more

This week, @johnconorryan.bsky.social begins a series exploring the externalities of the coal industry. While most of us have some idea that coal causes appreciable harm, we calculated that the cumulative externalities of the coal industry are a staggering EIGHT TIMES its gross revenue.

A Lump of Coal
