70 Sustainable Energy Ideas

­

1. Change to LED Lights: LED bulbs use significantly less energy and last much longer than incandescent ones—saving you money while reducing your energy footprint.

2. Go Solar for Small Scale: Consider solar-powered gadgets like phone chargers and outdoor lights to begin your journey to solar energy at a manageable pace.

3. Use Power Strips: Connect multiple appliances to a single power strip. Switching it off when not in use eliminates energy vampires that still draw from the socket.

4. Opt for Better Insulation: Good insulation means less need for heating and cooling, which not only maintains a comfortable environment but also cuts down your energy usage.

5. Upgrade Your HVAC Filters: High-efficiency filters not only purify the air better but also help your heating and cooling systems run more efficiently.

6. Wind-Dry Clothes: Skip the dryer and hang your laundry out to dry. It saves energy and adds a lovely scent to your clothes.

7. Reverse Ceiling Fans: In colder months, reverse the fan direction to force warm air downwards and optimize your heating system’s efficiency.

8. Service Your Car Regularly: A well-maintained vehicle is more fuel-efficient, producing less CO2.

9. Maintain Proper Tire Pressure: You can improve your gas mileage by keeping your tires inflated to the proper levels.

10. Drive Slower: Reducing your speed not only increases your safety but also significantly reduces your carbon footprint.

11. Choose Green Energy Plans: Many utility providers offer plans that allow you to support renewable energy sources.

12. Draft-Proof Your Home: Blocking drafts will make your home more comfortable and reduce the strain on your heating and cooling systems.

13. Plant Trees: Trees absorb carbon dioxide from the air, offering a natural way to offset your carbon emissions.

14. Utilize Public Transportation: Commuting via public transit lessens your personal carbon footprint.

15. Telecommute: Whenever possible, work from home to cut out the pollution from your daily commute.

16. Organize a Carpool: Sharing rides with friends or colleagues is a fun way to cut down on the number of vehicles on the road.

17. Use Reusable Grocery Bags: Single-use plastics are a major environmental hazard—reuse bags for a quick win.

18. Buy Local: Supporting local farmers and businesses reduces the carbon emissions from transportation.

19. Eat Less Meat: Adopting a plant-based diet, or even cutting down your meat intake, can drastically reduce your ecological impact.

20. Compost Organic Waste: Divert food and yard waste from landfills, lowering the methane emissions that contribute to global warming.

21. Unplug Chargers: Even when not in use, chargers plugged into the wall use ‘phantom’ energy.

22. Be Energy-Conscious When Using Water: From shorter showers to only running full loads in your dishwasher, less hot water means less energy used.

23. Insulate Your Water Heater: Wrap your heater in an insulating blanket to reduce heat loss and thus the cost to heat your water.

24. Use Energy Star Appliances: These products are certified to use less energy, helping you cut costs and energy consumption.

25. Repair Leaky Faucets: A small drip can add up to gallons of water wasted every day, and it’s wasted energy to treat the water as well.

26. Upcycle Household Items: Turn old furniture, clothing, and other items into something new—eliminating waste and the need for new manufacturing.

27. Zero-Waste Grocery Shopping: Shop at stores that allow you to bring your own containers to avoid single-use packaging.

28. Turn Off Lights: It may be a simple one, but it’s a classic for a reason. Non-essential lights need to be off.

29. Use Natural Light When Possible: Open those curtains and let the sunlight work its magic.

30. Install Dimmer Switches: Adjust the lighting in a room to fit your needs and use only as much power as necessary.

31. Install Skylights: Another way to maximize natural light, and often quieter than traditional windows on a breezy day.

32. Fix or Replace Seals Around Windows and Doors: Keep the weather on the outside and your heating & cooling inside.

33. Tune Up Your Refrigerator: A well-maintained fridge runs more efficiently, saving power.

34. Use Smaller Appliances When Cooking: Microwaves, toaster ovens, and slow cookers use much less energy than your stove or oven.

35. Cook in Batches: Prepare multiple meals at a time to minimize the energy output from cooking.

36. Use a Pressure Cooker: Not only does it save time, but it also saves a whole lot of energy.

37. Turn Off the Water Heater When You Leave: If you’re gone for extended periods, switch off the heater to save energy.

38. Use Smart Power Apps: There are several apps that can help you manage and monitor your energy usage.

39. Plant a Rooftop Garden: If you have a flat roof, consider planting a garden to insulate your home, reduce stormwater runoff, and even grow some produce.

40. Create a Thermal Mass: Consider using dense materials to retain and release heat, like concrete or stone common in passive solar homes.

41. Weatherize Old Windows: Window quilts, cellular shades, and weatherstripping can make a big difference to the efficiency of your home without sacrificing charm.

42. Use Portable Solar Panels: Perfect for camping trips or power outages, they soak up energy from the sun to charge your electronics.

43. Insulate Your Pipes: Wrap insulation around your hot water pipes to keep the heat where you want it—in the water.

44. Make the Most of Curtains: In summer, keep out the heat by closing curtains during the day. In winter, keep warmth inside with heavier drapes.

45. Employ an Energy Monitor: See exactly how much energy and money you’re using in real-time, and adjust your habits accordingly.

46. Set Your Freezer and Fridge to Optimal Temperatures: -18°C for freezers, and 3°C to 5°C for the refrigerator for maximum efficiency.

47. Use Cold Water for Laundry: It saves energy and is usually gentler on your clothes too.

48. Consider Your Ironing Needs: Maybe a quick shake-out of your clothes is sufficient, and you can skip the iron for another day.

49. Turn Off Heat Dry in Dishwasher: It’s typically an optional setting and can save a good deal of energy.

50. Opt for Rechargeable Batteries: They take less energy to manufacture than regular batteries and can be used repeatedly.

51. Use Motion Sensing Lights: For outdoor and indoor security, use lights that only come on when they sense movement.

52. Choose Non-Toxic Household Cleaners: Not directly an energy saver, but it reduces your eco-footprint and is important for a holistic green lifestyle.

53. Capture Rainwater: Use a rain barrel to water your garden and landscaping, decreasing your need for municipal water supplies that require energy to treat.

54. Install Reflective Shingles: Keep your home cooler in the summer with shingles that reflect rather than absorb heat.

55. Buy Secondhand or Recycled Furniture: Reduce manufacturing demand and the energy it entails.

56. Work with Landscaping to Keep Your Home Cool: Plant trees for shade, bushes to break the wind, and vines to cool the air that reaches your home.

57. Implement Passive Solar Heating: Position your home to make the most of the sun’s warmth, using windows and slabs to store and distribute heat.

58. Use Proper Solar Energy Storage: Invest in a good battery or energy storage system to make the most of your renewable energy.

59. Use Fans Instead of Cranking the AC: Ceiling fans and standing fans use a fraction of the energy—plus, the breeze feels great!

60. Choose Efficient Cooling Systems: When the time comes to upgrade, opt for high-efficiency air conditioners or innovative cooling alternatives like geothermal systems.

61. Save Energy in the Kitchen: When cooking, keep the oven door closed as much as possible and don’t peek—every time you open it, heat escapes.

62. Upgrade to High-Efficiency, Low-Flow Toilets and Showerheads: They save water, which in turn saves the energy needed to treat and pump that water.
