In most of the world, electricity isn't generated from one single source — it's a blend, and natural gas plants often set the final price even when they only supply part of the grid. Oil and gas prices are tightly linked: when oil spikes from a supply shock, gas usually follows within weeks, because the two compete as industrial fuel sources and are extracted together in many fields.

There's also a lag most people don't expect. Utility companies often lock in fuel contracts months in advance, so a price spike today can show up on your bill in the next billing cycle, or the one after — meaning the "explanation" you're looking for is a headline from last quarter, not this morning's news.

And it isn't just direct fuel cost. Higher energy prices ripple into everything the grid needs to operate — transportation of equipment, maintenance, even the plastic in the wiring — so the final markup on your bill is usually larger than the raw price jump in oil itself.

The bottom line: Your electricity bill is a delayed echo of a global commodity market — by the time you see the increase, the event that caused it may already be old news.
