New Breakthrough in Energy Storage – MIT Engineers Create Supercapacitor out of Ancient Materials::Constructed from cement, carbon black, and water, the device holds the potential to offer affordable and scalable energy storage for renewable energy sources. Two of humanity’s most ubiquitous historical materials, cement and carbon black (which resembles very fine charcoal), may form the basis for
I’m surprised that per capita, the absolute worst is Qatar with 3x the consumption of the US. The average US citizen however consumes ~2x as much as a German, Japanese, Iranian, French or Irish citizen.

The data kinda seems off though. How is an Icelandic citizen using 3x as much as a US citizen? Did they completely get rid of fossil fuels or something?
Qatar and Iceland are both rich nations in an inhospitable climate.
Makes sense they’d be near the top in heating/cooling.
Iceland has so much renewables with water and geothermal, they can use it however they want.
Most of Europe and Japan is pretty mild most of the year. I wouldn’t be surprised if a very large chunk of that difference is simply climate, a lot of the USA gets very cold/hot.
It’s not so much about what citizens consume. Per capita energy use is not the same as average household energy use, it’s just the total energy consumed divided by population. So it will include industrial consumption.
Iceland produces plentiful electrical energy from hydro and geothermal power. Because electricity was so abundant it was very cheap, and because it was so cheap large energy intensive industry developed, such as aluminium production. Industry consumes the vast majority of electricity in Iceland.
