Around 1.1 billion people worldwide—roughly the population of India—are still living without access  to electricity with most concentrated in Africa and Asia.

Another 2.9 billion rely on wood or other biomass or fuels for lighting and cooking resulting in indoor and outdoor air pollution attributable for around 4.3 million deaths each year.

A lack of electricity also renders these people without any form of safety at night and costly batteries are the only form of electricity to operate appliances that more developed households take for granted.
Even charging a mobile phone to have some source of communication is an effort in these rural areas.

Introducing Window-sol – the complete off-grid electrification solution for underdeveloped rural areas and electricity savings tool for electrified homes.

Window-sol is a solar powered device that is fitted on the inside of a window casting or onto a window sill. Installation is easy and no wiring is required.

·The device is equipped with a remote operated led light that can provide up to ten hours of light. This light can be used as a main light source in dwellings not equipped with electricity, as an electricity saving light in electrified homes or an emergency light in the event of a power outage.

·A build-in battery charger charges 8x AAA or AA sized batteries that powers the various functions of the window-sol device. Only 4 batteries are used at any one time, leaving 4 batteries free as backup power or to be used in other appliances.

·A USB port on the device delivers 5V DC that is perfect for charging cell phones or tablets. In rural areas this function will ensure that there is always a source communication available. Electrified homes can use this function to minimize unnecessary electricity waste by leaving charging devices plugged in.

·Window-sol is also equipped with a motion sensor alarm that picks up movement at the window sill area. When the sensor detects an intruder it sets of an alarm with flashing lights. This is meant to identify the point of entry to the occupant and make the perpetrator visible in the dark or to scare the intruder away. Safety is a great asset in both developed and rural areas.

These functions makes Window-sol a necessity in rural areas and in electrified homes.

Some interesting facts about electricity consumption in South Africa

With future load shedding being an almost certain possibility in South Africa, it is essential that we all adopt
energy efficient behaviour. A great deal of energy is wasted in South Africa. From industries to households,
we use more energy than is necessary to fulfil our needs – either because of old and inefficient equipment, or
because of bad habits.

A significant saving in electricity can be achieved by using off-grid solar powered lights when moderate light is sufficient to perform a task at home or in the work-place.
Lighting is responsible for around 17% of the total electricity usage in South Africa and around 12% globally.

By using alternative sources of lighting this figure can be dropped dramatically. Savings of more than 5% in total consumption is achievable.

Small changes make a BIG difference!

Small saving measures count. If every one of us in South Africa with access to electricity managed to save 1 kWh per month, this would add up to 348 million kWh. This is enough electricity to supply 580 000 people with 50 kWh a month for one year!

The first step in saving electricity is to understand how electricity is used in your home. South African households, on average, use electricity in the following ways:

Space heating and cooling: 18%
Lighting: 17%
Fridges and freezers: 8%
Cooking: 11%
Consumer electronics: 5%
Consumer electronics on standby mode: 15%
Geysers: 24%
Miscellaneous: 2%

How Mobile Phones Are Changing the Developing World

Technology has the potential to lift people out of poverty. All signs point to the developing world skipping past the eras of landlines and desktop computers and going straight to mobile. That potential for two-way communication is changing the face of international development. “For the first time ever, we’re able to have a clear line to people who are in the middle of nowhere to give them a sense of a future, information, opportunity and choice,” says Chris Fabian, co-lead of UNICEF’s Innovation Lab.

By 2020, more people will own a phone than have electricity.

The proliferation of mobile phones will continue as mobile data traffic jumps tenfold over the next four years, according to a study by Cisco. In many developing countries, even a basic “dumb” phone is a luxury.
That’s poised to change in the next four years. By 2020, 5.4 billion people around the world will have a phone, according to Cisco’s annual report on mobile traffic growth. In comparison, 5.3 billion people will have electricity, 3.5 billion will have running water and 2.8 billion cars will be on the road.

Energy consumption from mobile phone charging

A 2012 study at the Lawrence Berkeley National Laboratory found that an idle charger drew 0.26 watts on average; this figure goes up to 3.68 watts when a phone is attached and charging, and drops down to 2.24 watts when the phone is attached and fully charged. Overall, the cost is a handful of pounds over 12 months.

Npower puts the figure at £3.50 a year for the average household. Some quick and very rough calculations suggest that if all UK phone users unplugged after charging, enough energy would be saved to power a town the size of Canterbury — once you look beyond your own energy bill it suddenly it starts to take on more significance.

Householders waste £134million a year overcharging gadgets such as mobile phones and laptop computers, according to a study.
One in five Britons leave their devices plugged in once the battery is full because they are scared of running out of power when they leave the house.
But one in ten admit they are simply ‘too lazy’ to pull the plug even though it costs them money.
The most overcharged devices are laptop computers, mobile phones and iPods at 43 per cent, 41 per cent and 10 per cent, respectively, the study found.

The positive impact that affordable, off-grid electrification solutions can have.

“Electricity or power is one of the largest barriers to overcome poverty”

Almost one in four people live without power worldwide. Without electricity, these people are at a disadvantage in nearly every aspect of their lives. Having electricity means the ability to study at night and get an education. It means the difference between subsistence farming and back-breaking labor, and having the technology to create large enough crop yields to make a living. It allows people to have and power cell phones, which are being used across the developing world for mobile banking and to access the Internet. In fact, a recent Time article suggests lack of electricity or power is one of the largest barriers to overcoming
poverty. According to the article, “as long as those hundreds of millions remain in the dark, they will remain  poor,” and yet bringing electricity to areas that have none lacks global funding and attention. It’s not even part of the Millennium Development Goals.

11% of SA households still without electricity.

The percentage of South African households with access to electricity had increased by 8.2% between 2002 and 2012, from 77.1% to 85.3%; however, a large amount of households were still without electricity or could not afford to use adequate electricity to satisfy their needs, Statistics South Africa (Stats SA) said onThursday. According to its General Household Survey (GHS), in 2012, 1.45-million, or 11%, of South African households did not have access to electricity, while another 3.6%, or 578 005, households accessed electricity informally or illegally. Print Send to Friend 2 2 Out of the 3.6% without formal access to electricity, 73.1% were connected to an informal source that the household paid for, while 11.7% made use of illegal connections.
