Some are but there are nylon teabags and pyramid teabags made with plastic, and apparently even paper teabags often use glues made of plastic. These days you have to specifically seek out a brand that explicitly says they have no plastic in their bags or just buy loose leaf.
We have solar panels, battery backup and a plug in hybrid car. It gets us just about anywhere locally we need to go without needing gas. We just got a 3d printer and I’m already thinking of dozens of things around the house I can fabricate now. We have a VR I can use to work out downstairs (beat saber!). Not to mention this cool miniature computer with internet access I can use anywhere I go.
Hoping to add a garden in the next year or so to grow herbs, fruits and veggies.
