Here are a few ways you can save energy at home and outside:



  • Switch electronic devices off when you’re not using them.
  • Use a timer for your air conditioner that is automatically programmed according to your schedule. Rather than running it all day, the air conditioner can turn on just before you come home.
  • If you own a clothes dryer, try to use it only when you are pressed for time. If you have the time, dry your clothes in the ‘old fashioned’ way: by hanging them up either indoors or outdoors. You can purchase a drying rack or simply hang your clothes around your home. This can be one of the best energy cuting decisions, as dryers consume more energy than any other appliance.
  • Always clean full loads when using washing machines, tumble dryers, washer-dryers or dishwashers. The fuller the load, the more energy efficient the cycle is.
  • Look for eco -cycles on your domestic appliances. Most modern washing machines and dishwashers have them.  They are designed to use less water and electricity than traditional daily programs.
  • Boil water in a hot pot, or kettle. uses only a third as much electricity as a saucepan on an electric hob.
  • Position a fridge or freezer out of direct sunlight and away from an oven or other heat source.
  • Set the proper temperature in the fridge and freezer.  A change of one degree can effect energy consumption by 5%. Freezers should operate at -15°C while fresh food compartments should be held at around 4°C to 6°C.
  • Turn off, empty and clean the refrigerator and leave the door ajar when away for long periods.
  • Vacuum the condenser coils at the back or underneath your fridge or freezer. Thick dust can reduce their efficiency by up to 25% if left unchecked.
  • Check energy consumption before buying a new TV.  The bigger your TV, the more power it consumes. But some technologies are more power hungry than others, whatever the size.
  • Replace incandescent light bulbs with compact fluorescent bulbs, or the newer LED bulbs which use dramatically less power. Keep in mind that low-energy light bulbs can last ten years or more. The average for a traditional bulb is one year.
  • Try using your car one less day per week. With a little planning, we can all use our cars less and save both money and carbon emissions.
  • Shut off your engine if you will be idling the car longer than two minutes.
  • Consider the lifetime energy costs as well as upfront price when buying new appliances. In most cases you will find that the energy efficient model will be cheaper when you take the up front cost and the operating cost together to form the overall life cycle cost of the appliance. This will only become more apparent as the price of energy continues to escalate.
  • Consider combo air and heat units in each room, as in hotel rooms.

Energy Efficient

"Best-Practices"

Moving Forward with Eco-Friendly ways of Living

Development and its Dependence on Natural Resources

 

How to counter act waste with energy: "How do we make sure that we can all have a good quality of life without disturbing natures delicate balance, making sure that everyone has a fair share in our resources and that future generations are assured of the same quality.”



• Building homes in such a way that they are warm in winter and cool in summer

o New technologies now-a-days allows you to build homes from clay that have the same strength (or better) than cement
o In a heated home, such ceilings and insulation can save 40% of the energy costs

 

• Energy efficient devices​

o Energy efficient light bulbs last for up to five years and use 30% less electricity

 

• Use the right energy source for the right activity

o Gas is better for space heating and cooking than electricity
o These include wind, solar and biogas. Wind energy is especially useful along coastlines. Solar energy is good in most of South Africa and rural areas have already benefited greatly from the establishment of solar home systems. 

 

• Biogas digesters

o A biogas digester is a septic tank, a closed sanitation system existing in a particular area and not linked to a complicated sanitation system requiring treatments works. As many as 200 homes can be attached to a biogas digester and indeed in some parts of the world this form of sanitation is very popular. There are 11 million biogas digesters in China

 

• Grey waste water system

o Grey waste water is the water that comes from basins and baths as opposed to black water, which comes from toilets. Grey water can be used again to flush toilets, or it can be filtered to irrigate gardens

 

• Rainwater harvesting

o Harvesting rainwater for household use saves on the amount of potable water you use on tasks such as gardening, cleaning or flushing toilets

 

• Landscaping

o Planting Trees on certain sides of the house to use natural light and shade

 

• Waste recycling

o Reduced need for rubbish dump sites and landfill space that is expensive to establish and run
o Create a few jobs where people sort and recycle waste
o Allow for the re-use and recycling of natural resources like tin, aluminum, paper, glass and plastics
