The energy suppliers in my area all have contracts I do not agree with. My gas & electric service may be cut in a couple weeks.
What’s my best move? I need enough electricity to power a mid-sized refrigerator (but could downgrade to a minifridge if needed), a few lights, router, laptop.
My boiler is gas but I have an old previously used mazut tank and furnice which I could possibly get working again with some effort.
Not sure what to do for cooking. Maybe use a portable electric cooktop.
I’d recommend reading this article: https://arstechnica.com/science/2023/01/i-disconnected-from-the-electric-grid-for-8-months-in-manhattan/
The author probably went further than you want to go, but it’s probably got some good tips to minimize your power usage.
