How these are written
Every post opens with a direct answer of forty to sixty words, then explains it properly.
Primary sources first — the regulators, the grid owner, official statistics — each one listed with the date we checked it.
Posts are tagged by region, because your lines network changes what you pay for every unit.
Every post is checked against its sources and reviewed before publishing, and passes automated checks on its sources, dates and links.
