OK for one, like the roads network, homes and offices couldn't pay for the electricity grid without industrial loads (which includes datacenter). The roads you drive on are paid for by registration and gas taxes, which 80% come from semi trucks. So let's get over this "they are costing us money". Yes power is getting more expensive because demand is growing. Thats ok. What is not OK is the lack of supply growth. We have far too many regulations and protections (especially from the NIMBY crowd) to build electricity production like say China does. The difference?
In China, if the government decides to build a power station, infrastructure, power lines, or solar fields, it will be built, and I dare anyone to try and stand in the way and say no. You'll disappear fast and the government will say you were taken to prison for being against the Chinese people's progress. In the US, regardless of what is tried, giving a few years to figure out if you can proceed despite the environmental, aesthetic, and contractural lawsuits is common practice. That is the difference. If a power company buys land, and they tick the environmental regulations (which should be lower), then the project should commence and regulators need to at that point step aside. No one will die (they dont have a mass die off in China), and supply will drive down costs.
The high costs are trying to tell you to stop using as much because others need what limited supply there is and are willing to pay more for it than you. Want more? Make more.
