Progress in Decarbonization: Power Sector
📌 The level of atmospheric $\text{CO}_2$ has increased by over 50% since the Industrial Revolution, leading to a global temperature rise of over $1^\circ\text{C}$.
⚡ Renewable energy sources like solar and wind now account for over 30% of global electricity generation, with over 4,000 GW capacity built almost entirely since the year 2000.
⚙️ Countries like Uruguay are achieving near 100% renewable electricity (e.g., 10 straight months on a clean grid), and places like South Australia aim for this by 2027.
🇨🇳 China is building approximately twice as much new wind and solar as the rest of the world combined, driving its emissions trajectory toward a peak soon.

Decarbonization of Heating and Transport
🚗 Electrification is gaining traction: in Norway, nine out of ten new vehicles bought last year were EVs, and in China, most new cars are electric or hybrid.
🔥 In regions with cheap electricity, like Norway (hydropower) and China (solar/wind), electrifying heating (heat pumps) and transport is becoming financially sensible.
📈 In Norway and China's Guangdong Province, electricity usage accounts for around 47% to 51% of total energy consumption, significantly higher than the global average of just over 20%.
🌍 Policy acceleration is evident, with Ethiopia banning internal combustion engine vehicle imports in 2024 to encourage EV infrastructure.

Hard-to-Abate Sectors and Natural Sinks
🔥 Decarbonization efforts are expanding to steel (approx. 7% of emissions), with 43% of planned new furnaces globally being electric, using alternatives like green hydrogen.
🧱 Cement production (second most traded commodity) relies on carbon capture units being retrofitted to existing plants as changes to the chemical recipe are difficult.
🌳 Protecting natural carbon sinks has seen success: emissions due to land use change have reduced by 30% since 2000, and Amazon deforestation has halved in the last two years.

Global Climate Trajectory and Outlook
📉 Current government policies suggest projected warming will stabilize between $2.2^\circ\text{C}$ and $3.4^\circ\text{C}$ by 2100, with the best guess being $2.7^\circ\text{C}$.
🎯 If medium-term targets are met, warming could be limited to $2.1^\circ\text{C}$, showing that every fraction of a degree saved matters.
💰 The energy transition is now primarily driven by economics: globally, twice as much was invested last year in clean energy and grid upgrades as in fossil fuels because renewables are now cheaper.
🔮 Despite political shifts in the US, the transition is considered inevitable due to global investment trends, highlighted by the Middle East rapidly expanding solar projects (e.g., UAE's world's largest round-the-clock solar and battery facility).

Key Points & Insights
➡️ Global emissions from electricity generation have likely already peaked two years ago, driven by massive renewable buildout, even amidst rising energy demand from sectors like AI.
➡️ The shift to electrification in heating and transport is directly tied to the falling cost and increasing share of renewable electricity, making electric systems more cost-competitive.
➡️ Political setbacks (e.g., US policy changes), while having impacts, are unlikely to derail the global transition because major emitters like China, Europe, and the oil-rich Middle East are heavily investing in renewables for economic reasons.
➡️ Continued climate action—influencing votes, employers, and spending—is crucial to ensure the transition accelerates fast enough to limit warming below $2^\circ\text{C}$.
