It’s a high capacity storage system that’s simplicity itself. Use excess wind and solar to raise heavy weights. Keep them at a height for as long as you like. Lower them to generate electricity.

At scale, a single “vault” with 10,000 bricks will have an annual output of 27 GWh, sitting on only 14 acres of land. The bricks are … [Read more...]
Behaviour Change: strategies and case studies for reaching net-zero by 2050
Technological solutions on their own are unlikely to deliver emissions reductions at the speed and scale required to reach net zero by 2050. Daniel Crow, Insa Handschuch, Gabriel Saive and Leonie Staas at the IEA look at a suite of policy-driven citizen “behaviour changes” that should be used to bridge the gap. The impact will be greatest in advanced economies where energy intensity is highest. Meanwhile, in emerging economies the good habits put … [Read more...]
COP26: a strategy for tackling “imported deforestation”
Palm oil, beef, cocoa, coffee, soy, and other agricultural products are responsible for deforestation in the producing countries. Of the 10m hectares of tropical forest lost each year, two-thirds can be unambiguously attributed to agricultural expansion and international trade is responsible for about half of this. The EC is due in December to unveil a legislative proposal to address the issue. Alain Karsenty and Nicolas Picard, writing for IFRI, … [Read more...]
Germany’s highest court rules climate laws are insufficient, violate rights, unfairly burden future generations
In an unexpected decision widely hailed as historic, Germany's highest court has ruled that the government's climate legislation is insufficient, and lacks detail on emission reduction targets beyond 2030. Sören Amelang, Kerstine Appunn, Charlotte Nijhuis and Julian Wettengel at Clean Energy Wire run through the background and the consequences of the case brought by youth activists and NGOs. Legal experts say the decision “significantly … [Read more...]
