Energy Saving Myth #1
Less energy is consumed if you leave your lights on rather than turning it off and on several times.
Truth - Leaving a lamp on consumes more energy than turning it on and off, as needed.
If the bulb is on, it is using electricity, and if it’s off, it isn’t. It doesn’t take any more electricity for a light bulb to turn itself back on. If you really want to save energy and money, make it a habit to turn off your lights, when not needed.
Energy Saving Myth #2 Turning your computer on and off wastes energy
Truth - Today’s computers are more energy efficient than ever before, and by turning them off when not in use, you can save a great deal of energy and money.
You can also take advantage of built-in energy-saving features such as the “sleep” function that essentially puts your computer to sleep when not in use and wakes it when you go back to it. Again, this saves what would otherwise be a lot of wasted energy.
Energy Saving Myth #3 Electronics do not consume energy when they are switched off
Truth - It is a good habit to switch off your electronic appliances like TV, video games, etc. when not in use. But, to believe that this will save energy over leaving them on is really not true.
These devices continue to suck power from your outlets when they are off in the form of ‘standby power’, which allows the device to power up again quickly. Always unplug the appliances when not in use to avoid this hidden energy consumption.

An iron consumes as much energy as ten 100 watt light bulbs.
Improve ironing efficiency by use the permanent press feature on your washer and dryer. Removing clean laundry promptly from the dryer, and fold immediately - many items will require no ironing, or just a quick press.

Humans have also been affected by lightning for centuries which is evident from the more than 50 known gods of thunder in ancient mythology. Lightning research however only started in the 18th century when Benjamin Franklin conducted experiments about electricity in thunderstorms, with his kite experiment being the most famous. His work paved the way for lightning research around the world.
In the 19th century, spectrometry and photography became the new tools for lightning research, but was replaced in the 1970s when electric and magnetic field measurements began a new era in lightning research. Lightning is an atmospheric phenomenon that has been studied extensively, however many questions remain unanswered. Extensive research around the globe has resulted in answers to many of these questions and provided insights into the science of lightning.
South Africa made significant contributions to the field of lightning research with names like Schonland, Anderson, Proctor, Eriksson, Malan and Geldenhuys being internationally recognised for their contributions to the field.
Early lightning research was conducted at the Council for Scientific and Industrial Research (CSIR), which also operated a network of about 400 lightning flash counters. The data from these lightning flash counters were used to produce the first lightning flash density map of South Africa which could be used to get an idea of the distribution of lightning across the country and was used up until recently for lightning safety standards. The CSIR also operated a 60m high lightning research mast in Pretoria for 15 years from which direct measurements of lightning discharges could be made.
Eskom, the major power utility of South Africa, operated a network of six Lightning Position and Tracking System lightning sensors that was mainly used for the monitoring of power lines and the correct distribution of the infrastructure.
It was not until 2005 that the South African Weather Service installed a state of the art lightning detection network (SALDN) across the country, which enabled South Africa to detect cloud-to-ground lightning with great accuracy for the first time. This new lightning detection network can detect 90% or more of all cloud-to-ground lightning and accurately position a lightning stroke within 500 meters. This new network of sensors paved the way for new lightning research in South Africa.

The South African Weather Service has been predicting a lot of thunderstorms lately, similar to the post below, so ensure your appliances are safe, by using Clearline’s protection products!
Lightning is the sudden discharge of a large amount of electrical energy that needs to go somewhere for equalisation and your electronic appliances are usually the equaliser. Large electrical surges, or ‘spikes’ are sent into the electrical appliances, which cannot withstand the electrical surge and basically ‘burn out’.
There are numerous ways that lightning can get into electrical appliances:
* Lightning can strike the air conductors directly and surge voltages, even from kilometres away, can enter into your installation. This surge voltage is then passed to ground through your equipment which can lead to damage or complete destruction of your equipment.
* When lightning strikes an object, (a building, tree or pole etc.) high currents at fast wave fronts occur causing large electromagnetic fields which are then induced into your electrical and data communication cabling. Equalisation then occurs which could cause damage to your equipment.
* When lightning strikes a structure, (a building, tree or pole etc.) a high voltage potential exists for the duration of the strike at the point of contact of the structure to the ground. Due to resistivity of the earth, decreasing voltage potentials will be experienced along the current paths moving away from this point. Should you have electronic equipment referenced to different earth systems while connected to each other via copper cables, equalisation will tend to occur via the copper cables resulting in equipment damage.
Luckily for you, Clearline is continually adapting and developing new products for affordable lightning and power surge protection, and power conditioning, so you can rest assured that your appliances will be much safer when lightning strikes!
