There are strong indications that Light Emitting Diode, LED, a semi conductor device that emits visible light when an electric current passes through it, will dominate the world by 2020.
The output from LED, ranges from red (at a wave length of approximately 700 nanometers), to blue-violet (about 400 nanometers).
Some LEDs emit infrared, IR, energy (830 nanometers or longer), and as such, the device is known as an Infrared-Emitting Diode, IRED.
Generally, LED light bulbs are a more environmentally friendly alternative, to incandescent bulbs, and they consume lesser energy, thereby providing more Kilowatts of electricity to be channeled for other usage.
From statistics across the world, we use not less than 19, 320, 360, 620 MWh of electricity a year.
Going by figures from the LEDLight.co.uk, China consume 5,463,800,000 MWh, with 458 per person; United States of America, USA, 4,686,400,000 MWh approximately 1,683 per person.
Russia follows suit with 1,016,500,000 MWh (808 per person); India 938,823,000 MWh (101 per person); Japan 859,700,000 MWh ( 774 per person); Germany 582,500,000 MWh (861 per person); Canada 524,800,000 MWh (1,871 per person); Brazil 483,500,000 MWh (268 per person); South Korea 482,400,000 MWh (1,038 per person); France 451,100,000 MWh (804 per person) and United Kingdom 323,300,000 MWh (622 per person).
Unfortunately, Africa was no where to be found in the ranking, despite having a closer look at the per persons electricity usage statistics, America uses 1,683 MWh, when compared with 101 of India and 458 of China.
If para-adventure, China uses the same per capital usage as that of the U.S, it would imply that it uses more energy than the whole world combined, presently.
Aside that, countries with high numbers of usage have a considerable size of population.
Bringing it back to Africa, which is either too hot or too cold, it will invariably have the highest per person electricity use level, as much of the energy are either channeled in using heaters or air conditioners.
India for instance, in a bid to maximise its electricity usage and channel the excess to other areas of production, in 2015, launched the Domestic Efficient Lighting Programme, DELP, designed to distribute 770 million of LED lights bulbs to houses across the country.
In an investigation conducted by LEDLight.co.uk Indian gambit, 770 million LED bulbs have proved to the world, that with LED light bulbs, nation’s of the world can significantly cut energy consumption, which can be channeled for other industrial usage.
In 2013, about 19 million of 140 million streetlights fitted, were LEDS.
The same was the case in 2012, where 2 million luminaries were installed into tunnels and roadways.
While in 2011, LEDS represented 40 percent of the domestic home lighting market.
Forbes are presently predicting that the LED market shares might grow to 70 percent by 2020.
Asia being the major driving force, according to McKinsey, will make 45 percent of the global general lighting market, while China, Japan and India, will also contribute significantly.
To achieve this feat, there are plans to inject 10 billion LED bulbs by 2020.
