I often see people argue that clean energy is not reducing emissions, because it just adds to rather than replaces fossil fuels. This argument is deeply misguided – clean energy built since 2005 has displaced 23 billion tons. I dive in over at The Climate Brink:
theclimatebrink.com
What if the world hadn't built wind and solar?
Clean energy does not simply “add to” global energy use; it displaces fossil sources that would otherwise get built.

Big Oil remains the most significant obstacle to reducing emissions and limiting climate harms. It’s important to understand the long history of that.

🥰 📣 BREAKING NEWS 📣 France has announced a climate roadmap that aims explicitly to phase out coal by 2030, oil by 2045, and "gas for energy purposes" by 2050!! This is a historic moment, the first time a major economy has pledged *specifically* to phase out fossil fuels. 🙌 💚
Faraco said France had decided to push ahead on its own after a proposal for a global fossil fuel roadmap was blocked at the COP3o climate summit in November. Brazil, which was steering the climate negotiations, agreed to pursue a voluntary roadmap process instead and has asked willing
countries to make submissions. Frustration at COP30 led to the creation of the Santa Marta conference, which is taking place outside the UN process and is being co-hosted by Colombia and the Netherlands. Nearly 60 nations were in attendance, from the European Union and major fossil fuel producers Canada and Norway, to developing oil giants Angola and Nigeria and small island developing states like Tuvalu. Nations are not expected to produce any binding commitments but a set of proposals for countries wanting to move their
own economies away from fossil fuel reliance. The conference takes place against a backdrop of soaring fuel prices and a global supply crunch stemming from the Iran war, and energy security has
been a prominent theme.
