The old "multiply by 7" rule is a myth. Dogs age rapidly in their first two years, then slow down. A 1-year-old dog is roughly equivalent to a 15-year-old human.

Switch to LED bulbs — LED bulbs use up to 80% less energy than incandescent, lasting 15–25x longer. Use smart power strips — automatically cut power to devices when the main device (e.g. TV) turns off. Optimize your air conditioner — set to 78°F (26°C) in summer; each degree lower adds ~3% to cooling costs. Run laundry in cold water — about 90% of a washing machine's energy goes to heating water. Check your refrigerator seals — worn gaskets force the compressor to work harder; replace if they fail the "paper test". Use time-of-use rates — if your utility offers TOU pricing, run dishwashers and dryers during off-peak hours.
