Biofuels are a land-wasting dead end. The same cropland used for utility PV would produce an order of magnitude more clean energy. Stop funding biofuels. Invest in solar, storage and EV infrastructure now. hannahritchie.substack.com/p/biofuels-v... by @hannahritchie.bsky.social
We could produce a lot of electricity on the land used for biofuels
About enough to meet current global electricity demand.

Just sent out this free piece. There was a weird and widely spread attempt in the media yesterday to create a fiction, that Trump's peace plan for Ukraine and Russia was a rogue operation by Steve Witkoff. That finally fell apart--and it’s important that it did. open.substack.com/pub/phillips...

Evidence shows communist bureaucracies were no better at reducing inequality than capitalist democracies and welfare gaps in health and living space persisted despite egalitarian aims: cepr.org/voxeu/column...
Soviet communism was not more successful at reducing inequality than other regimes
Inequality is a major concern for many economies, prompting the question of whether some regimes are more effective at reducing inequality than others. This column uses measures of welfare including health status and living space to show that, despite Soviet communism’s aim of radical egalitarianism, it failed to eliminate inequality as effectively as promised. While communism did lead to higher upward mobility, strong welfare systems in Western Europe and bureaucratic shortcomings in the East created a landscape where equality in welfare distribution was broadly similar, despite the paths to social advancement being markedly different.
