⚡️ Energy
Energy production and consumption is becoming cleaner, cheaper and decentralized. With connected devices you as a consumer can take control of your energy consumption. Here you will also find content about batteries, smart grids, nuclear and other innovation in the energy field.
📉 China's CO2 emissions continue to decline – the peak may already have been passed
China's carbon dioxide emissions fell by one percent during the first half of 2025 and continue the downward trend that began in March 2024. The declining trend opens the possibility that China's emissions may already have reached their peak, years before the "before 2030" target.
📉 An AI prompt uses less energy than nine seconds of TV – 33-fold reduction in one year
Google's AI infrastructure has reduced energy consumption by 33 times and carbon footprint by 44 times over one year.
📉 Solar power with batteries became 22 percent cheaper in one year
The cost of solar power with batteries dropped 22 percent during 2024 and 43 percent since 2019. Solar power with batteries now costs around 100 dollars per megawatt hour in sunny cities, which is cheaper than coal and nuclear power.
