Nationwide average prices for industrial customers are slightly less than half of residential prices. That's before special negotiated discounts for the largest loads. We pay double or more, in other words.

Python was awarded a funding grant, funding grant asked Python foundation to remove all diversity and inclusion initiatives they have.
Python foundation said no and rejected the grant.
If you use Python, send a few dollars to the charity to keep it going. I’m pushing a dono on behalf of ScamGuard.

Strong relationship here between wholesale electricity price and how close you are to a data center.
We reallly need to see data centers bringing their own (clean) energy with them

Friends, I am in the market for editing work at the moment. I really enjoyed a stint editing stories for BBC Future earlier this year and am currently looking for more such opportunities! Anything from news & features to book chapters and so on. I'm game.

It was a call I couldn't ignore.
I was formally invited by the Danish EU Presidency to Luxembourg to speak about industrial electrification and energy efficiency directly to the energy ministers from every single one of the 27 EU member states on the 20th of October.

Cheap energy shifts wealth from producers to consumers. That has led to political backlash - but it also means that if you make energy decisions based on politics you will end up poorer. Stop politicizing market economics and this is so much easier. www.indystar.com/story/news/e...
Wind and solar aren't politically popular, but they've been profitable for 2 Indiana counties
Building wind and solar energy capacity in rural America isn’t about politics, and it isn’t about climate change. It’s about money.

You're standing on unlimited energy right now.
Beneath your feet, the Earth's core burns at 10,800°F.
That heat has been there for 4.5 billion years, and it'll be there long after we're gone.
