I will add to the planting piece, there are now LED grow lights that fit into a standard lamp. That means that if you live in an apartment like mine (that has pathetic sunlight) a trip to target/IKEA for some cheap lamps and a visit to whatever store in your area carries a good range of LED bulbs will probably have you set up to turn your living room into a herb/peppers/other small vegetables grow room.
With expensive power you’d want to look into timed switches. LEDs are pretty efficient but not enough that you’d want to leave them on all day. That said, it’s the same power usage as a standard LED bulb so if those aren’t breaking the bank switching should not be a problem.

Also recycling center swap shops and Buy Nothing groups often have plenty of cool old lamps for free
Is this cost-efficient? Pretend I live somewhere with expensive power
