Re: So 35% of elec is residential
Again - not convinced it's that unusual.
We're not saying "<tech giant Q> used 14% of a country's electricity", but that a whole sector, which the country has heavily encouraged, is using that much energy.
What's the largest non data centre industrial segment in terms of electricity usage? (I don't know, it's not broken out anywhere that I've seen).
In terms of energy usage the road haulage industry uses 15% of all energy, air transport takes 21%...
Between 2005 and 2019 (again, last figures I can see) services gradually increased their share of electricity consumption from 35.3% to 42.9%.
Most of the data centres also probably came with investment towards renewable generation, allowing coal plants to be retired. Between 2016 and 2019 there was a massive drop in the amount of coal being used to generate electricity and a substantial increase in renewables. (84% and 54% respectively, though coal has clearly been on the way out for a while)
Is it an industry that uses a lot of electricity? Yes
Is that surprising? I don't think so. It's long been known that cooling and power are two of the most expensive things to deal with when running computers (at least when running lots of them).
Interestingly the CSO publish "energy use per employee" broken down by sector, and that's been remarkably stable for "services and public sector" - suggesting that even as data centres are using significant amounts of electricity they are also employing a proportional number of residents.
Do they use 14% of the electricity on the island, I can well believe it. I just don't think it's particularly shocking.
