Saving energy with lighting
We are all paying a lot of bills every month and one of them is always bigger than we have expected. That’s the one for the electricity used. With the price of electricity increasing every year, it is a time to think of the ways to cut the cost of energy. I can give you some tips on saving energy with lighting and you can decrease your bill up to 20%, because lighting could waste a huge amount of energy.
- Are you turning off the lights when you leave the room?
Most of the people are not turning the lights off when they leave the room even if they won’t come back in the near half an hour or even several hours. We can make a quick calculation, what are the negatives from such negligence. Let’s take for example the living room – a room with an area of at least 25 square meters, needs approximately 250 watts of lighting from incandescent bulbs. If you leave the living room for one hour than you will waste 250W, multiplied by 365 days, makes 91.25KW – 10 GBP. If you do that in all your rooms, than you can spend more than 50-60GBP on these lights, that are not really used. And these numbers are for a small flat or house. Imagine the amount of money that you can save on a bigger house. There are some smart lighting systems that you can switch on and off with voice, noise or even a command, but they are too expensive. So it is just a good idea to make a habit to switch the lighting off in the room that you are leaving.
- Use of task lighting
When you are reading a book or working at the laptop, you don’t need to have light everywhere in the room. You can switch to task lighting, which is closer to you and gives you enough light to perform the tasks. You can turn off the general room lighting which is always more energy consuming than the task lighting. Good solution is to have floor lamps or table lamps. On a yearly basis you can save up to 30GBP by using lights only where you need them.
- Saving energy with dimmers
In the past the dimmers were made with resistors and even when you decrease the light the same amount of power was used. It was just a waste of energy. The modern technology with triac integrated in the dimmers is now saving energy when you reduce the illumination. If you decrease the illumination with 50%, you will save approximately 40% of energy.
- Switch to Compact Fluorescent Lamps (CFL)
I love the old incandescent bulbs, but they are already fading in the past, so the only option is to change them with the new CFL bulbs, which are 5 times more energy saving. Of course, they have some negatives like containing small amount of mercury and they are more expensive.
How much will you save by using CFL bulbs compared to the traditional incandescent? You have to sum all the bulbs installed in your home , than you have to think of the time that you use them – daily and multiply it by 365. A small house has approximately 25 bulbs at 60W – 1500W. Using CFL will make it 300W. You will save more than 50GBP every year
- Make your house extremely energy saving
There are bulbs that are 9 times more energy saving than the traditional incandescent bulbs. Yes, those are the LED bulbs. Changing all of your current bulbs to LED will cost you a lot, but you will save much more energy. Such an investment is good, because over the next few years you will cut the cost of the electricity bill to the minimum. If you have the budget to invest in such type of lighting – go ahead and do it.
- Use the daylight as much as possible
This advice depends on what are the windows that you have. Their size and orientation. There is nothing better than the natural sunlight and the best of all is that it is free.
- Paint the interior in light colours
Use white or cream colour for your walls and ceiling. I’m a real fan of interiors designed in light colours as they are making me much more comfortable. Even the furniture can reflect a lot of light and make the room brighter and well illuminated.
