⚡️ 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.
🔋 Denmark's first molten salt battery can power 100,000 homes for 10 hours
Denmark has launched a 1 GWh molten salt battery that can store renewable energy for up to two weeks with minimal loss. The system uses industrial byproducts from chlorine production and achieves 80-90 percent efficiency for co-generation of heat and electricity.
📉 Have China's CO2 emissions peaked? Declining for the first time thanks to clean energy
China's carbon dioxide emissions fell by 1.6 percent in the first quarter of 2025 despite sharply increased energy demand. China's electricity sector emissions have decreased four times previously. However, the current reduction is the first time the main cause is growth in clean energy production.
⚡ An AI query uses as little energy as a microwave for one-tenth of a second
A simple text query to AI uses only 114 joules - equivalent to running a microwave for one-tenth of a second. Generating a high-quality image requires 2,282 joules, which corresponds to five and a half seconds in the microwave.
🔋 Researchers are developing liquid batteries that can be printed in any shape: "Like toothpaste"
Researchers have created batteries with electrodes in liquid form that can be 3D-printed without losing capacity. The battery can be stretched to double its length and has been tested through 500 charging cycles without performance loss.
👩💻 ChatGPT uses less energy than an hour of Netflix
One hour of Netflix watching equals the energy required for between 300 and 3000 ChatGPT prompts. Ending your shower one second earlier saves enough water to compensate for 40 ChatGPT prompts.
📺 Jonas Birgersson on the historic launch of EnergyNet
Mathias Sundin has spoken with Jonas Birgersson about the launch of EnergyNet and the start of Project Energy Society.
🔋 Solar panels and batteries dominate new power generation in the US in 2025
Solar energy and battery storage will account for 81 percent of the total capacity increase, with solar energy representing over 50 percent. While renewable energy grows, coal power continues to decrease. The US will decommission twice as much coal power capacity this year compared to last year.
🔋 Part 2: Towards the energy society – the world's first EnergyNet is launched & Broadband Jesus is resurrected
Broadband Jesus waited until one week after Easter to resurrect. Now as Electricity Jesus.
⚡ Wind power is big in Texas – expected to double during 2025
Together with solar power, wind power accounted for a record share of 29.8 percent of total electricity production in Texas during 2024. Texas is the largest wind power producer in the USA.
