Gaurav Gupta, the director for Asia of the development consulting firm Dalberg, tells a story about theuntethered life. “You want to sit next to a beach and have a laptop on your lap, and you want to be connected tothe world,” Gaurav says. “But you don’t want any wires.”

Off-grid power aligns what’s good for the poor with what’s good for the planet.

We go off the electrical and phone grids by choice, Gaurav says. We buy cellphones, install Wi-Fi, buyeco-friendly high-end camping stoves and water purifiers. But around the world, billions of people are off-grid bynecessity: they live without wired electricity, piped gas and water, or sewers. The two worlds are linked. “Whatwe want, they need,” he said in a TEDx talk in February in Mumbai. “There is huge innovation going on aroundthe world to serve your needs because you want to play Angry Birds longer.”

Tech innovators don’t see the rural poor as a viable market. They don’t put money into inventing better andcheaper ways for very poor people to light their homes, cook or run appliances off the grid. “But because of the

things you desire, these things have become reality,” Gaurav said. “LED technology, very efficient batteries anda falling solar panel price have suddenly allowed lights to be delivered to off-grid households at a fraction of thecost. “

The need is overwhelming. More than a quarter of the world has no electricity; about half have no piped water,2.5 billion have no piped gas. The poor turn to substitutes that are dangerous and expensive. For light, most of the poor burn kerosene — and they are paying 600 times more for each unit of light than people who useincandescent lamps. Kerosene costs the poor 10 percent of their income or more — and it is a major contributorto indoor air pollution that kills 2 million people a year. On top of all that, it doesn’t produce very much light.

Gaurav says the poor who are off the grid spend up to 615 percent more than on-grid people for the equivalentamount of electricity, 175 percent more for cooking fuel, 175 percent more for drinking water.

More wiring and pipes is not a viable solution. There is no political will for the expensive task of electrifyingAfrica. The grid, in fact, is growing more slowly than the population.

A clue to one answer comes from a more familiar product: the mobile phone. About half of Africans own one,and 75 or 80 percent have access to one. Africans have leapfrogged over the landline. In the process, they havecreated an information revolution whose effects on agriculture, commerce, health and education we cannot yetimagine.

But if off-grid communication is bringing change, even more will come from off-grid power — wind, smallhydro, biomass, but mostly solar. Power drives almost everything else — cooking without gathering wood andinhaling smoke, clean water, radios, fans, eventually TVs. Also, this second revolution is needed to make the first

revolution happen. How do people without electricity charge their mobile phones? Solar lights increasingly comewith that capacity.

Power brings more than consumption. It brings safety: people can walk at night, women no longer have to rangeso far to gather wood for cooking. It brings education: children can study after dark. It brings prosperity: storescan stay open longer. Producers can get the tools they need to produce more — a milk-chiller for dairy farmers,pumps to irrigate crops.

One huge benefit of off-grid power is that it aligns what’s good for the poor with what’s good for the planet.Pro-poor hasn’t always meant pro-environment — as poor countries develop, they consume more fossil fuels.But with off-grid it’s different. “Providing basic services to off-grid households …can only be done in an

environmentally responsible way,” said Gupta.

“Because the grid hasn’t arrived, the dominant fossil fuel is really kerosene, for cooking and lighting,” said JustinGuay, associate director of the international climate program at the Sierra Club. “Replacing that kerosene withsolar lanterns, home systems and cooking stoves can have a tremendous impact on the environment, in additionto increasing livelihoods and health.”

In 2009 there were some 300,000 solar lamps in use in Africa. By the end of 2012, there were 4 million, andsales are doubling each year. Gaurav points out that solar lighting is not only a service. It can also come in theform of a product a family can buy at a local store for $10. This shift is useful, as products are rapidly improving;battery hours and brightness are increasing even as prices drop.

One light is often not enough, so there are other models. A family can buy a more ambitious solar lighting systemthat offers several lights and phone charging.

There are also new products for village entrepreneurs. A set of solar panels and rechargeable lights, for example,creates a business that delivers lanterns to customers every morning and evening, picking up the spent lanterns atthe same time.

Or a village entrepreneur can buy a power plant in a box: solar panels and wiring for 20 or so households. Thatperson is now the village power company, but his wiring need only be a few hundred yards of cable, rather than afew hundred miles.

Compared to mobile phones, off-grid power is still in its infancy. The technology is advancing; the bottleneck isthe business model. To grow to mobile phone proportions, off-grid power needs solutions to two differentfinancing problems.

The macro problem is how to attract investment to the sector. “Commercial institutions don’t see this asbankable yet,” said Guay. “It’s not true — many business models are quite sustainable — but it’s a question of belief. Bankers are quite conservative and they are not comfortable in these markets, with a new segment of thepopulation and a new business model.”

International banks and development agencies are helping to lower the barriers. The World Bank and its private-sector development arm, the International Finance Corporation, set up Lighting Africa, Lighting Asia andLighting Global to try to bring down barriers to entry in the market. These organizations provide informationabout consumers and what they want, set quality standards and certify products that meet them.

Guay argues that it’s not enough: public money is needed to get private investment started. A recent letter from20 off-grid power entrepreneurs and nongovernmental groups asks the World Bank to use the I.F.C. to create apool of capital that can be invested at lower rates of return. That capital would “reduce perceived risk and raiseawareness of the viability of this sector,” the letter said.

One valuable source of financing for off-grid energy is the U.S. Overseas Private Investment Corporation.

Because of a cap on the greenhouse gas emissions of OPIC’s energy investments, a quarter of those investmentsare now in clean energy — among them, off-grid projects. But in June the House of Representatives introduced abill that could have the effect of shifting OPIC’s energy portfolio towards fossil fuels. The Senate is discussingways to remove the cap entirely.

This legislation is brought to you by gas companies. Surely if the United States government should listen to anyindustry’s special pleading, it should be that of the off-grid entrepreneurs. There is a market failure here, and atemporary pool of loans might solve it.

Anil Raj, the chief executive of OMC Power in Uttar Pradesh, India, signed the letter. But the growth of his ownbusiness has convinced him no heroic measures are necessary. “What’s needed for [the sector] to grow is for it

to be profitable,” he said. “Then you don’t need any extra stimulus. We’re almost there.”

OMC Power has 11 micropower plants using sun, wind and biogas in Uttar Pradesh, India’s most populous state,and is growing so fast it expects to have 100 plants by April, 2014. (That scale, he said, will allow OMC todeliver power next year at the same cost as the grid — and OMC’s cost, Raj predicts, will continue to drop.)

OMC’s plants charge lanterns and power boxes (these can run a few lights and appliances) that are delivered tocustomers’ homes twice a day. But what sets OMC apart is that each of its plants also has an anchor client — amobile phone network tower, connected by cable to the micropower plant. These towers would otherwise run ondiesel, expensively — fuel and power eat up 40 percent of a mobile network operator’s cost. But OMC hassigned 10-year contracts with mobile tower companies — including the giant Bharti Infratel — to supply themwith power.

Raj said that OMC expects to earn more from its consumer products than its tower contracts. “But they givestability and confidence to investors,” he said. These anchor clients have allowed OMC to grow with loans fromIndian commercial banks. “There are going to be a thousand OMC-like companies in the next two years,” Rajsaid.

The micro problem is finding ways for the poor to pay. Some will be able to afford single lights or light packages,especially if they see the savings these will bring — many of the world’s very poorest people have found ways tobuy mobile phones, after all. But more will need to pay as they go, with the savings from what they’d bespending on kerosene. Simpa Networks in Karnataka, India, uses a progressive purchase model: customers installa solar system and pay for energy in small increments, as they do for phone airtime. When they have paid the fullcost of the system, it is theirs — free energy from that point on.

M-KOPA in Kenya uses a similar system — with the twist that it takes advantage of Kenya’s hugely popularmobile banking system, M-PESA. Former M-PESA executives founded M-KOPA, which markets a $200 systemmade by d.light that provides three bright lights and phone charging, and sells it in stores all over Kenya. Buyersput down an initial deposit and then pay 40 shillings (45 cents) for each day’s light via M-PESA. (They would bepaying 50 shillings a day for kerosene.) When they have completed payments, usually within a year, they ownthe system. M-KOPA has so far sold 25,000 units — 5,000 in the last month.

“When you have villagers who are interested in putting up solar panels on the roof or want a solar lantern, theycan go buy it off the shelf and bring it home the very same day,” said Guay. “You see an immediate impact —you can displace kerosene and allow your children to study at night without waiting. It’s no longer about buildinga huge centralized station and waiting for that power to trickle down to poor. It’s about the time that matters —

now.”

Correction: September 12, 2013

An earlier version of this article incorrectly characterized efforts in the Congress to move OPIC's investments

away from clean energy towards fossil fuels. A House bill was introduced in June; it was not passed. The Senate

is not considering a version of that bill; it is discussing the issue.
