Bigger wind turbines make cheaper energy. The sector’s unexpectedly rapid successes in designing and building bigger and bigger turbines has been one of the major success stories of the clean energy sector. In 2023, the biggest turbines in the world will start generating electricity off the coast of the UK. Each of General Electric’s Haliade X turbines stands 260m high from sea level and can generate 13MW at under ÂŁ50/MWh (€56/$61). But how big … [Read more...]
Seven ways for the U.S. and Europe to enhance energy security and advance climate goals
Ending reliance on Russian fossil exports will need the U.S. and Europe to work together, explain Joseph Majkut, Nikos Tsafos and Ben Cahill at the Center for Strategic and International Studies.

Net-Zero world: calculating the cost of stranded assets, including wrong-skilled “human capital”
Most calculations of the costs of stranded assets abandoned and replaced by the net-zero economy have been missing the biggest element: human capital. It’s not sufficient just to total up the assets and supporting infrastructure for coal, gas, old-style buildings, machines, vehicles, etc., says Dan Chester at Lancaster University and co-author of the paper “Stranded Human and Produced Capital in a Net-Zero Transition”. Worker output is not only … [Read more...]
Europe’s Deep Buildings Renovations need to quadruple
The European Green Deal must grasp the opportunity to kick-start buildings renovations, says Thibaud VoĂŻta at the IFRI Center for Energy & Climate, summarising his report “The Renovation Wave: A Make or Break for the European Green Deal”. A lot of European buildings are old, and progress is slow. Stiffer regulations have helped, and household energy efficiency has risen by 30% since 2000. But the number of deep building renovations completed … [Read more...]
