Myth 1: Fluorescent lights should be left switched on, as the energy wasting in starting them is greater than the energy that would be used if they were left on permanently. Lights should always be switched off when not in use. The amount of energy used to start up a fluorescent light is negligible compared to the normal demands of the light if left on full time. Bust myth
Myth 2: Leaving a water tank heater on continuously will save energy because the water will not have to be heated from cold each time it is switched on. Water heaters should only be left on continuously during busy periods of use. When not in use, they should be switched off to reduce energy consumption and save on energy bills. Bust myth
Myth 3: Recycling uses more energy than it saves. Recycling materials to make new products saves significant amounts of energy when compared to using raw materials, which require energy-intensive extraction and processing. Bust myth
Myth 4: Water efficient products are not effective. Modern water efficient products have been specifically designed to operate using reduced volumes of water, and are just as effective as systems which use more water. Bust myth
Myth 5: Sustainability is expensive. Sustainability measures that reduce your waste production and/or energy and water consumption will reduce your bills. Although some measures will require investment, many can be achieved at low or no cost. For example, making sure that equipment is switched off when not in use. Bust myth
