Insulation. Reflectrix your attic. Seal off air gaps. Add as much blow-in that you can. Heat pump water heater. You can buy an entry Ecoflow River that will use solar before battery. Could run a fridge off of it.

Next time you look for a laptop, make sure its got usb-c powerdelivery, i can charge mine from a 50w-solarpanel + Usb-Controller + Powerbank, currently limited by the Controller to 18w (12v, 1.5a~), but that would be another device off the Grid. other than that: look into Kitchen stuff, my Fridge uses Alot of energy (if its ancient, maybe calculate how much it uses (KWh per Year / Powerbill ), and consider how long the savings would take, to buy a new one ). Same with the Cooking-Stove, i am looking to buy Insolatet Pans currently.

Anker solix battery and some solar panels to charge it, you could do most of your house off that. Not sure which brand is best to go with but that at least let's you look up some example products. That gives you a plug and play type of setup for the solar/battery system but it will may cost more than building your own. How would you reduce energy consumption without using less energy? Not sure if this counts as obviously it is using less energy... Either way, turn the heating down for the house, even more in rooms you don't use often. Then get a heated blanket or hot water bottle to warm your self up. Firewood might be a cheap energy source to look at. Heat a bunch of water (or any large mass) with a short clean high temp fire and then let the water keep an area warm for a long time. Like a giant water bottle really, you could pump it through a radiator depending on the scale you want. You can heat yourself or an entire house like this if you want to but that depends on your DIY skills or what quality of workmanship you see as acceptable. You can get easy to use plastic pipes and quick attach fittings that are very easy to use your self at home. Check their temp limit, 60c seems like a common maximum so I would heat up a water barrel that can take that or more and use a thermometer to check it's not going over the limit for the pipes. If you go copper them you can go until it starts to boil.

use compost to make biogas, use biogas to drive a heat engine generator.

Haha yeah I got that. Still not trying spent over $500 at most. And even that is stretching it. Just dipping my toes in for now.
