It's the irony of the push for more efficiency. In theory you could have the equivalent of a 90's PC now with a fraction of the power consumption, but in practice any gain is used to create more powerful chips and do more calculations. There's a saying that was more about financial budgets, but tl;dr expenses will fill up the budget.

In my country there's irony as well. On the one side, power companies and the government invest a lot in green power production, offshore windmill farms and solar farms and the like. But at the same time, companies like Microsoft and Google come in and have datacenters built that use up all the energy that those 'green' alternatives produce. We would've been carbon neutral years ago if it wasn't for the increase in power consumption that follows production.
