  • Take a shower instead of a bath to save hot water.
  • Use an aerated shower head to control the amount of water used.
  • Do not open a hot water tap unless you really want hot water.
  • Insulate roofs, windows and doors to keep houses cooler in summer and warmer in winter. This can be done by using the latest materials at relatively high cost or simply by using newspaper to seal gaps.
  • Use appliances carrying the Energy Efficiency label.
  • Choose the right appliance for the job and save:
    •  An electric kettle uses about a third less energy than a stovetop kettle.
    • A toaster oven uses up to half the energy of a conventional electric oven.
    •  For faster meals, a pressure cooker uses at least half the energy of a regular pot.
    •  An electric slow cooker makes soups and stews using much less wattage than a stove or oven.
    •  Use a microwave rather than an oven. Or braai more.
    •  Switch off all appliances at the plug to save stand-by power
  • Replace regular light globes with energy saving lamps. They use about 25% of the energy and last 6 to 8 times longer.
  • Use low energy lamps for exterior lighting, with timers or light sensors for switching
  • If the sun is shining, make the most of natural light.
  • New LED lights are even better than compact fluorescents

  • With electric hobs, match the pan size to the element size. For example, a 12cm pan on a 16cm burner will waste more than 40% of the heat.
  • Only boil as much water as you need when making a hot drink – kettles use lots of power.
  • Consider using a pressure-cooker. By building up steam pressure, it cooks at a higher temperature, which considerably reduces cooking time and energy consumption.
  • Food cooks more efficiently in ovens when air can circulate freely. If possible, stagger pans on upper and lower racks to improve airflow.
  • If you have a self-cleaning oven, use the feature just after you’ve cooked – that way, the oven will still be hot and the process will require less energy
  • Use a microwave where you can.
  • Use a gas stove where you can.

  • Use appliances carrying the Energy Efficiency label.
  • Swap older top-loading washing machines for more efficient front loaders which require less water to function. An energy efficient washing machine can make a 30% energy saving and are very effective at lower temperatures.
  • Using a 40°C wash cycle rather than 60°C equates to a 30% electricity saving.
  • Make up a full load before washing.
  • Hang clothes up to let them dry naturally. If you do use a tumble dryer, do loads back to back – dryers take time and energy to reach the right temperature.
  • Buy clothes that do not require ironing
  • Use appliances carrying the Energy Efficiency label.
  • If you have the means, buy an A-rated energy-efficient fridge-freezer. It could save you up to 33% on your annual electricity bill. New, energy-efficient refrigerators use half the energy of standard fridges from the early 1990s.
  • Manual defrost freezers are generally more efficient than automatic defrost models if they are properly maintained. The freezer should be defrosted if ice build-up is thicker than 5mm.
  • Vacuum the coils in the back of your refrigerator twice a year to maximize efficiency.
  • Make sure the fridge is not positioned next to the stove, dishwasher, or exposed to direct sunlight, which will make the appliance work harder.
  • If your refrigerator has an energy-saver (anti-sweat) switch, it should be on during the summer and off during the winter.
  • Use appliances carrying the Energy Efficiency label.
  • Turn equipment off when it is not in use – even machines on standby use up to 30 watts of electricity.
  • Printing can be the most energy-intensive step, so edit on-screen and print only the pages you need.
  • Heat and pressure fusing is the most common photocopying technology and is also the most energy-consuming. Invest in a heat and pressure fusing machine that is equipped with an energy-saver feature that can save energy consumption in idling mode by at least 50%.

South African Tap And Flow Rate Gap Analysis https://dithetogroup.co.za/sanediv2/south-african-tap-and-flow-rate-gap-analysis/ Sat, 21 May 2022 21:33:14 +0000 https://dithetogroup.co.za/sanediv2/?p=9543

CLASP’s 2021 report titled “In-depth Assessment of Water Efficiency Opportunities in South Africa” found that standards for taps and showerheads could address the country’s linked water and energy crises by reducing the use of water and electricity needed to heat some of that water. As a next step, the report recommended a gap analysis between the various South African National Standards that were perceived to require high flow rates, in contrast to international trend of standards requiring decreasing flow rates in support of sustainability.

National water week an opportunity to tap into new standards https://dithetogroup.co.za/sanediv2/national-water-week-an-opportunity-to-tap-into-new-standards/ Sat, 21 May 2022 21:28:38 +0000 https://dithetogroup.co.za/sanediv2/?p=9538

South Africa can significantly improve water and energy efficiency by aligning its tap labelling programme with international standards, according to a new study released ahead of National Water Week marked on 20 to 26 March 2022. The week aims to raise awareness and call to action renewed value for this scarce resource.

In 2018, the National Water and Sanitation Master Plan identified a water supply deficit of 17% by 2030 for the country, putting water efficiency under the spotlight at a time when parts of the country were feeling the pinch of prolonged drought conditions.

The future of micro digesters in south africa https://dithetogroup.co.za/sanediv2/the-future-of-micro-digesters-in-south-africa/ Thu, 31 Mar 2022 20:30:47 +0000 https://dithetogroup.co.za/sanediv2/?p=9500

The South African National Energy Development Institute (SANEDI) commissioned the University of Johannesburg’s Process, Energy and Environmental Technology Station (UJ PEETS) to take stock of the current status of micro-digesters and the wider state of the technology in South Africa and globally. UJ PEETS, together with the DSI/NRF/Newton Fund Trilateral Research Chair in Transformative Innovation, the Fourth Industrial Revolution and Sustainable Development (UJ-TRCTI), conducted research over the period of two years, with significant levels of stakeholder engagement that has culminated in the development of a Sector Development Plan (SDP). This Plan outlines three pathways that the micro-digester sector in South Africa can take to ensure growth and sustainability of the sector by 2030. The first pathway focuses on increasing uptake of this technology in rural areas. The second pathway looks to pilot micro-digester use in urban areas, especially urban gardens, food establishments and small housing developments. The third pathway is cross-cutting and focuses on actions to create a supportive enabling environment relating to skills and training, financing, regulation and policy.

SANDF Takes A Green Leap Ahead Of Global Recycling Day https://dithetogroup.co.za/sanediv2/sandf-takes-a-green-leap-ahead-of-global-recycling-day/ Fri, 18 Mar 2022 21:35:35 +0000 https://dithetogroup.co.za/sanediv2/?p=9548

On Friday 18 March the world will mark Global Recycling Day to bring to light the benefits of recycling waste for the environment, businesses and people. The day was first recognised by the United Nations in 2018 and has since birthed countless initiatives by governments, civil society groups and the private sector that have impacted environmental action and awareness in profound ways.

This year the SA National Defence Force (SANDF) will be no exception. The military is taking its “green soldiering” environmental concept to the next level by installing biogas plants that will enable two military bases to reduce or eliminate the use of fossil fuels to cook meals for about 220 people a day.
