Aside from solar panels, as others have mentioned, I have a few other suggestions for things to get/do:

• Hydroponic garden
• Sewing machine
• Heat pump water heater
• Heat pump a/c
• Induction stovetop
• Upgrade insulation
• Compost bin
• Tools to repair common items
• Promote the use of libraries and support their growth into other communal resources
• Only buy things when needed

As others have said, there isn't much that a single individual can do against climate change, but let me explain my suggestions. Some of the most carbon intensive activities include the transportation of items like food, clothes, and other goods. To reduce your impact, you need to reduce your reliance on this carbon intensive logistics network. By growing your own food, learning to repair what you own, and learning to sew, you're making a large impact on your personal contribution to climate change. By supporting the library, you're encouraging the use of a shared pool of communal resources, which also reduces your community's climate impact.

The other items are what you can do to improve the efficiency of your house, if you own it. Induction stoves are incredibly safe and a highly efficient cooking surface. Heat pumps are crazy efficient at both heating and cooling, so slowly replacing old appliances with high efficiency options as they fail will maximize the use of what you own before it gets replaced. Compost bins and insulation certainly aren't glamorous like the other tech options, but they'll also go a long way: Landfills create an anaerobic environment, meaning food that gets thrown end up producing methane, and single family homes consume a lot of energy because heat escapes from every wall open to the air.
