Myth #1: Solar PV only works in summer
There are plenty of sensible ways to save energy – these are the most common misconceptions when it comes to saving on your bills. Update your energy saving skills!
People tend to think that it needs to be a hot summer’s day for solar panel electricity systems, also known as solar photovoltaics (PV), to be doing anything meaningful. But, in actual fact, the warmer it is, the less efficient the panels can be. Solar PV works by capturing the sun’s energy using photovoltaic cells – it is the light from the sun, not the heat, that is being converted to electricity. Photovoltaic cells don’t need direct sunlight to work – they can still generate some electricity on a cloudy day.
Myth #2: Cranking down the thermostat cools your home faster
A sudden decrease in temperature setting won’t cool your home any faster and may actually cause you to spend more on air conditioning. Instead, you should turn the thermostat down a degree or two. If the air conditioner stops running and you’re still hot, bring the temperature down one degree at a time until you’re comfortable. Making gradual adjustments will keep the machine from working harder and longer than it needs to so you can save a little money.
Myth #3: Leaving a ceiling fan on will cool a room…even when you’re not there.
Fans cool your skin, not the air; they do not lower room temperature. A fan works by circulating the air in a space; when the air moves across the skin, we feel cooler even though the air temperature in the room remains the same. If a fan runs in a room when no one is there, no one is feeling its benefits, so it’s just wasting electricity.
Myth #4: Screensavers save energy
Screen savers are a left-over solution from a previous technology. Old CRT monitors needed screen savers to stop the screen image being "burnt into" the screen. Now that we have LCD screens this problem no longer exists. Fun as they are to look at, these days screensavers are just another program powered by your PC and do nothing in terms of reducing a computer’s energy consumption when it’s not being used. Try using sleep mode instead.
