- 95 percent in rural sub-Saharan Africa have no access to electricity.
- Solar power is a cheap, safe, clean alternative to kerosene lamps.
- Rural Energy Foundation supports local entrepreneurs to sell low-cost solar systems.
(CNN) -- In rural communities of Africa -- where more than 95 percent of homes have no access to electricity -- solar energy has the power to transform lives.
Globally, 1.5 billion people, one quarter of the world's population, live without electricity, according to a United Nations report.
Those who can afford any power at all spend large proportions of their income on kerosene for lamps or travel to larger towns to charge their batteries several times a week.
Burning kerosene contributes to indoor air pollution, which is estimated to kill 1.6 million people each year. Kerosene lamps also lead to fires that cause severe burns and deaths.
Solar energy saves families money as well as allowing children to study in the evenings and giving families access to information through radio and television and mobile phone chargers.

The light from a solar-powered bulb is also between 10 and 20 times brighter than from a kerosene lamp.
Among those bringing solar power to the world's poor is Rural Energy Foundation, a Dutch non-profit organization. It has now helped 450,000 people in sub-Saharan Africa gain access to low-cost solar power.
Rural Energy Foundation runs the SolarNow program, training independent retailers and technicians in nine countries to sell low-cost solar gadgets or home systems to people without electricity.
Last month, the organization was one of the international winners of the Ashden Awards for Sustainable Energy.
Willem Nolens, director of Rural Energy Foundation, said: "Lack of access to energy -- just as lack of clean drinking water -- is a cause of poverty, not just a result of poverty.
"Gaining access to electricity can be really life-changing. People can increase their productivity, children can study, read books and watch television, which allows them to be connected to the world.
"Whole villages can become self-sufficient once someone has a home solar system."
Rural Energy Foundation supports 250 independent local retailers in Burkina Faso, Ethiopia, Ghana, Mali, Tanzania, Uganda, Senegal, Mozambique and Zambia.
It does not provide the equipment, but identifies retailers and distributors and trains them in solar energy technology, marketing, sales and business administration, to help them to grow their own businesses.
Rural Energy Foundation also helps customers to access loans to pay for solar systems, which can usually be repaid within a year or two from the savings made on kerosene or charging batteries.
A full solar home system typically costs between $250 and $630, and a solar lamp between $25 and $40.
Local entrepreneurs can choose their own manufacturers and importers, but Rural Energy Foundation checks their quality and withdraws its support from retailers selling sub-standard products.
Ronald Schuurhuizen, Rural Energy Foundation's country co-coordinator in Uganda, said: "It's a hard life for people in rural areas of Uganda. Most people are subsistence farmers, collect scarce firewood for cooking, go to sleep when it gets dark and hardly ever travel out of their own areas.
"If you need to charge batteries, that often involves cycling 10 or 20 kilometers over hilly terrain to a charging station in a main town.
"The most important difference solar power makes for most people is the ability to charge mobile phones. Most of Africa has mobile coverage but most people have no way of charging phones.
"For those who can, it can change their lives. They can keep in touch with friends and family, and those in cities can use their mobile phones to send money to relatives in rural areas.
"Access to television is also life-changing for many people. Whole villages will crowd around a television set to watch the news. It opens up the world for them."
Rural Energy Foundation is not alone in bringing solar power to the world's poor.
D.light, the gold winner of this year's Ashden Awards and one of the brands sold by Rural Energy Foundation's retailers, has sold more than 220,000 solar lanterns in 32 countries, particularly in India and East Africa, benefiting around 1.1 million people.
D.light produces three different models of solar lanterns costing between $10 and $45.
Meanwhile, the American inventor Stephen Katsaros and his company Nokero claim to have developed the world's first solar light bulb.
The Nokero went on the market in June this year and it has already been tried in 33 countries.
"We've done everything we can to make this solar bulb affordable and long-lasting so the people who need it can afford it, and reap the benefits," said Katsaros.
"There are so many ways this product can change lives: It can help keep families and shopkeepers safe, help students study at night, eradicate indoor pollution, and reduce worldwide carbon emissions."
