- Don't use your phone

- Don't use your laptop

- Don't use your washer and dryer

- Don't use your TV

- Don't use your water heater

- Don't use your furnace

- Don't use your AC unit

- Don't use your dishwasher

- Don't use your refrigerator

- Don't use your car

- Don't use banks

- Don't go to grocery stores

- Don't eat at restaurants
