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
God, i wish my house used 10kwh of power per day. During winter that is more like 20 and during summer it can go as high as 30. We are doing projects to improve that, vut its a slow process with financial constraints.

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.
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.
Which makes sense. If industries didn’t have energy, citizens would be missing a bunch of other stuff…
The rest of your comment does make sense too.
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.
Yeah, i feel like the fridge uses that much by itself. Seriously though i have no idea where it all goes.
Yeah, i just looked and the minimum i have used all year is 661kwh which is ~22 per day. The house is 1000 sqft.
Shit… at my last house in Texas I averaged 37 kWh per day and that’s over a years worth of bills.
In the summer I’d be up over 60 some days.
Oh dear lord.
