(1/8) A few thoughts on the current debate about the #EUTaxonomy on sustainable energy finance, especially the classification of #gaspower and #nuclear. (2/8) #Nuclear power has a very peculiar risk profile. It certainly is climate-friendly, with small life-cycle CO2 emissions (like wind and PV). But its waste problem and nuclear accident risks are unique. Ultimately a value judgement whether or not these eco-risks are acceptable

We are in the midst of a huge technology revolution. In the 2010s, costs for solar PV have decreased by 85%, for wind power by 50% (@REN21 ), and batteries are repeating that pattern. Solar and wind are already the cheapest electricity option in most parts of the world. However, electricity currently only accounts for 20% of global final energy, because it is the most costly energy carrier. The remaining 80% non-electric are mostly fossil-based. Transitioning non-electric fuels to low-carbon will take much longer than decarbonizing electricity.

Thread on the key points. We are in the midst of a huge technology revolution. In the 2010s, costs for solar PV have decreased by 85%, for wind power by 50% (@REN21), and batteries are repeating that pattern. Solar and wind are already the cheapest electricity option in most parts of the world.
