13. Walk or bike to the store/work.
Only going to get a couple of items? Is it near enough for a 5 – 20 minute walk/bike-ride? Then it is definitely worth the ride/walk. It is healthy and reduces your carbon footprint. That is, no need to consume Carbon Dioxide (CO2) emitting energy sources like gasoline for cars, buses, or even the electric train/bus because the electricity still comes from a power plant that might produce CO2!
12. Use the rail system for commuting.
The train, subway, elevated-rail, which ever name it goes by. Taking the train to work is a greener choice than driving. Also, this avoids traffic jams and expensive parking (if in an urban city)!
11. Take the bus.
The bus is generally cheap, perhaps slower than driving or train, but it gets you to where you’re going. It is also a better alternative than driving your car.
Split the cost of your gas and save some emissions by carpooling. Also, take advantage of carpool lanes on the highway if available in your city.
Avoid paying parking at the train station by biking, walking, or taking the bus. Carpool to the train station with a friend, etc. Plan a route that is cheaper than driving and save emissions!
8. Turn off the lights.
If not in use they should not be on. Turning off lights saves energy thus saves on the utility bill.
7. Adjust your thermostat.
Even 3 degrees makes a differences in the work needed by your heat pump to cool or heat your area.
6. Reduce plug loads.
Disconnect appliances not in use. That is, disconnect the cord from the socket. Even though the television is off it still consumes electricity when plugged in. The same applies for kitchen appliances, computers, etc.
5. Keep doors and windows shut when heater/air-conditioner is on.
Only heat or cool the space you are in to avoid your heat pump (or cooling/heating source) from over-working itself. This reduces its energy consumption significantly.
At Home Retrofits:
Insulating the home is key to cut energy consumption for heating and cooling. Good insulation keeps heat outside when cooling and warmth from leaving your space when heating.
Windows: Insulation with high R-values is what achieves this. Look into replacing windows with high R-value windows. If in a hot climate then look into windows with low Solar Heat Gain Coefficients (SHGC); the less the SHGC value, the less heat will transmit through the window.
3. Solar PV panels.
Seek installing Solar PV panels on your roof to partially or completely cut your utility bill to zero.
