Artificial intelligence(AI)has already demonstrated its proficiency at difficult scientific tasks like predicting how proteins will fold and identifying new astronomical objects in masses of observational data[1].Now,recent results suggest that AI also excels at weather *** global predictions,GraphCast,an AI system developed by Google subsidiary DeepMind(London,UK),outperforms the state-of-the-art model from the European Centre for Medium-Range Weather Forecasts(ECMWF),providing more accurate projections of variables such as temperature and humidity 90%of the time[2,3].Other AI systems,including Pangu-Weather from the Chinese tech company Huawei(Shenzhen,China)[4],can also match or beat traditional global forecasting models.

In the South Boulder Canal near Denver,CO,USA,turbine blades that resemble the mixers used to stir cake batter in kitchens(Fig.1)spin in the rushing water[1].Each of the turbines,manufactured by Emrgy of Atlanta,GA,USA,generates up to 25 kW of electricity for the area’s grid[2].In an orchard in southern Italy,an arcade of solar panels stands above rows of citron trees,which are valuable for the essential oils in their fruits[3].The solar panels not only produce electricity for local homes,but also protect the trees from the sun,reducing their water use by 70%[3].These are two examples of a clean energy trend:integrating power-generation with other *** the approach called agrivoltaics,for example,farmers and ranchers grow crops or raise livestock around and beneath solar panels(Fig.2)[4].Experts hope that such add-on strategies can spare farmland,cut the environmental costs of clean energy development,supply extra income to landowners,and furnish other benefits[5,6].
