Super budget/DIY energy hacks (lemmy.world)

I just recently started using a solar charger to charge a 10k mah battery pack that I use to charge my phone every night. One device “off the grid.”

Short of installing solar on my home I’d really love to be able to charge a large battery that would output 120V so I could use household appliances “off the grid.”

Does anybody have some other energy hacks, or ways to reduce your energy consumption at home that’s not just “use less energy?”

Never gets hot enough to need more than a fan here really, but similar ideas should still apply. Cool the person instead of the house. So I've bottle or a small heat pump (old fridge, aquarium chiller) to cool water and pipe it around you in some way.

Downside is condensation, but not sure how bad that is if you have low humidity as we are always high humidity.
