New energy vehicles' share of sales and vehicles on the road in China by category is going up.
Annual change in China’s oil consumption in transport compared to energy transition pathways. Oil consumption has fallen in 2025 nearly as much as in 2020.
Trend in Earth Energy Imbalance (EEI) in CERES and CMIP6 models. The CERES data are shown from 2001 to 2023. The CMIP6 data are shown from 2000 to 2030. All EEI are given as 12-month running means. CMIP6 model mean is shown by a thick black line and individual models are shown in thin gray lines. Only one ensemble member for each of the models is shown.

Bar plot showing that starts of new power plants slowed in the 1970s, making nuclear power share of global electricity stop growing and plateau at around 380 GW.
Four bar plots showing the market share of ICE cars in Norway, China, Germany, and Italy going down. Except for two years in Germany and Italy when sales percentage of ICE cars went up.
Quote from article: Ecosystems? Listen a bit to Beinhocker, who is also the executive director of the Institute for New Economic Thinking at the Oxford Martin School. In the real world, he argues, “There is no such thing as the American economy anymore that you can identify in any real, tangible way. There’s just this accounting fiction that we call U.S. G.D.P.” To be sure, he says, “There are American interests in the economy. There are American workers. There are American consumers. There are firms based in America. But there is no American economy in that isolated sense.”

Two graphs. Global PV cell production and manufacturing capacity utilization (left) and market shares and module efficiency by cell type (right), 2010-2022. On the left, rising global capacity dominated by China and falling utilization rates. On the right, rising cell efficiencies and market share changes from BSF to PERC cell types.
Two maps of Germany. On the left, it shows that the anger with which local newspapers describe wind energy is higher in Eastern Germany. On the right, it shows the density of wind turbines across Germany, which is highest in the North and North-East.
