Trends in energy savings: six solutions to reduce your electricity bill

Published on

 

It seems obvious that the trend in housing is directed toward energy efficiency. There are two main reasons: to save on the electricity bill and to respect the environment.

One of the ways to reduce the electricity bill during the winter months is to reduce heating consumption, and this too can be approached along two pathways. On the one hand, by improving the heat insulation of the house, and on the other, with innovation; that is, with systems supported by new technologies to achieve a much more efficient power consumption.

As well as the heating, a significant part of the extra expense we suffer in our electricity bills is due to the inefficient management of electricity in the home, and this we can put right. To do this, we set out below a series of systems that will enable you to manage your consumption efficiently and to join the latest energy saving trends.

 

1. STAND-BY ELIMINATOR POWER STRIP

Several studies have revealed that switching electronic devices to standby mode represents 15% of the total electricity consumption in a house. Until recently, we used to switch electronic devices off manually, but now there are power strips that switch the equipment off automatically if they detect that it is in standby mode.

Besides, this type of strip allows items that work together to be grouped together. For example, if we have a personal computer, we can connect the CPU to the master socket and the rest of the associated devices (printer, speakers, external hard drives, etc.) can be connected to the slave socket of the same device. In this way, if the strip detects that the CPU is in standby mode, it will automatically switch off the rest of the items in the group.

 

2. SOLAR CHARGERS FOR YOUR MOBILE PHONE

The use of smartphones has spread rapidly over the last years. It is now common for each member of a family of four to have his/her own smartphone. This entails a high yearly electrical consumption, as the batteries of these telephones have to be charged at least once per day.

One solution to reduce this consumption is to use solar chargers. In general, these solar chargers hold a battery which charges as direct sunlight falls on it. It is this battery that then transfers the power directly to our mobile phone.

The main drawback of this system is that the solution is not eco-friendly, as we always need an extra battery to transfer the charge, and these batteries are not environmentally friendly due to the heavy metals contained in them. Another drawback of the system is that we depend on the sun for charging. Fortunately, Spain is a very sunny country, and this solution can save us a significant amount of electricity in our homes.

 

3. SMART REFRIGERATORS

Although this may sound like science fiction, Samsung is already developing a refrigerator with an integrated camera which connects to our smartphone. This way, while we’re shopping at the supermarket we can see, for example, if there are any courgettes in the fridge or not. But you’ve seen nothing yet- in the future it is expected that these refrigerators will be able to program the cooling temperature according to the food they contain, or may even contact the shopping centre to purchase the products required directly.

Obviously, these breakthroughs represent indirect energy savings. If the refrigerator is capable of adjusting the temperature according to the cooling requirements of the food, we will be optimising the power consumption, which will entail a reduction in our electricity bill.

4. SMART THERMOSTATS

Smart thermostats can be contacted directly by smartphone. If we notify the thermostat via smartphone that we’re on our way home, the phone will be able to send the expected time of arrival at home according to our location and the estimated traffic. Meanwhile, at home, in accordance with the estimated time of arrival and the existing temperature, the thermostat will be able to adjust the power of the heating, so that when we arrive, the temperature is optimal.

It is obvious that this type of system should be accompanied by the refurbishment of the house, if necessary, to obtain good heat insulation. In general, this can be achieved by replacing the traditional windows with thermal break windows.

 

5. SMART LIGHT BULBS

Smart light bulbs are equipped with a movement detection system that can identify whether we are in the room or not, and switches the light on and off. These must be bulbs whose useful life cycle does not depend on the number of on-off cycles, and do not cause a greater consumption if they are continually switched on and off. In these cases, the best option is to go for LED lamps.

 

6. SMART EQUIPMENT

It is foreseen that in the future there will be ever greater interconnectivity between all the appliances we have at home. In a few years, for example, it will be possible for the router to contact the technician directly in the event of detecting an anomaly in the Internet connection. In this way, we will avoid the bother of having to contact the telephone company ourselves to solve this type of problem.

If you think that the cost of your electricity bill is high, join these trends and you’ll see how your electricity consumption will fall.
