Lighting accounts for 15 per cent of a typical household’s electricity bill. You can cut your lighting bill and energy use by changing which bulbs you use and how you use them. Houses typically use a mixture of standard light fittings and downlighters or spotlight fittings. Energy efficient bulbs are available for both types of fittings.
There are two main types of energy efficient light bulbs available. Compact Fluorescent Lamps (CFLs) and Light Emitting Diodes (LEDs).
Both CFLs and LEDs are a cost-effective option for most general lighting requirements. LEDs are available to fit most fittings and are particularly good for replacing spotlights and dimmable lights, they are more efficient than CFLs and will save you more money in the long term.
LEDs use 80% less energy than a traditional bulb. Using just one bulb could save you £100 in its lifetime (and they last up to ten times longer than normal bulbs).
You can save money and energy by implementing control mechanisms and being conscious of how you use your lighting.
Home appliances can range from fridges and washing machines, to laptops and TVs. All of these contribute to the amount of energy used in your home; how much energy they use depends on how you use the appliances, how often you use them and how efficient they are.
Buying the most efficient appliances is an important part of reducing the amount of energy they consume. Look out for the energy ratings label and consider the size of the appliance you require. Energy ratings are generally given to products based on their size category. Generally speaking, the larger the appliance, the higher the running costs.
Remember though that even the most energy efficient appliances can waste energy if used ineffectively.
How water efficient are you? In Gibraltar, all of our potable water is produced via a process of desalination which is very energy intensive. In addition to this, we then use energy to heat water for showers, baths and hot water from the tap. Reducing unnecessary water wastage is therefore one of the best things we can do to lower our energy use and minimise our impact on the planet.
Heating and cooling your home is also an energy intensive process. Many homes in Gibraltar now have split heating and cooling systems installed in the main living areas to provide temperature control throughout the year.
