''' POWER TO THE STUDENTS '''
AROUND 1.8 billion people, or more than a fifth of the world's population, have no access to electricity, and a billion more have only an unreliable and intermittent supply.
Of the people
without electricity 85% live in rural areas on the fringes of cities.
Extending energy grids into these areas is expensive.
The
United Nation estimates that an average of $35 billion-$40 billion a
year needs to be invested until 2030 so everyone on the planet can
cook, heat and light their premises, and have energy for productive uses
such as schooling.
On current trends, however,
the number of ''energy poor'' people will barely budge, and over 16%
of the world's population will still have no electricity by 2030,
according to the International Energy Agency.
But why wait for top-down solutions?
Providing
energy in a bottom-up way instead has a lot to recommend it. There is
no need to wait for politicians or utilities to act. The technology in
question, from solar panels to low-energy light emitting diodes OLEDs, is rapidly falling in price.
Local, bottom-up systems may be more sustainable and produce fewer carbon emissions than centralised schemes.
In
the Rich world, in fact, the trend is towards a more flexible system of
distributed, sustainable power sources. The developing world has an
opportunity to leapfrog the centralised model, just as it leapfrogged
fixed-line telecoms and went straight to mobile phones.
But just the spread of mobile phones was helped along by new business models, such as pre-paid airtime cards and village ''telephone ladies'' , new approaches are now needed.
''We need to reinvent how energy is delivered,'' says Simon Desjardins, who manages a programme at the Shell Foundation, that invests in for-profit ways to deliver energy to the poor.
''Companies need to come up the innovative business models and technology.'' Fortunately, lots of people are doing just that.
Start
with lighting, which prompted the establishment of the first electrical
utilities in the rich world. At the ''Lighting Africa'' conference of
some years ago, at Nairobi, a World Bank project to encourage
private-sector solutions for the poor, 50 lighting firms displayed
their wares,-
Up from just a handful of a year
ago. This illustrates both the growing interest in bottom-up solutions
and falling prices. Prices of solar cells have also fallen, so that the
cost per kilowatt is half of what it was a decade ago.
Solar cells can be used to power low-energy LEDs, which are both energy efficient and cheap: the cost of a set of LEDs to light a home has fallen by half in the past decade, and is now below $25.
This could eliminate Kerosene lighting in the next ten years, the way cellphones took off in about 13 years,'' says Richenda Van Leeuwen of the Energy Access Initiative at the UN Foundation in Washington, DC.
That
would have a number of benefits: families in the developing world may
spend as much as 30% of their income on kerosene, and kerosene
lighting causes indoor air pollution and fires.
But
such systems are still beyond the reach of the very poorest. ''There
are hundreds of millions who can afford clean energy, but there is still
a barrier for the billions who cannot.'' says Sam Goldman, the CEO of
D.light.
His firm has developed a a range of
solar-powered systems that can provide up to 12 hours of light after
charging in sunlight for one day. D.light's most basic solar lantern
costs $10.
But the price would have to fall
below $5 to make it universally affordable, according to a study by the
International Finance Corporation, an arm of the World Bank. So there is
scope for further improvement.
It is just not new technology that is needed, but new models. Much of the ferment in bottom-up energy entrepreneurialism is focusing on South Asia, where-
570
million people in India, Pakistan and Bangladesh, mostly in rural
areas have no access to electricity, according to the International
Energy Agency.
One idea is to use locally
available biomass as a feedback to generate power for a village-level
''micro-grid''. Husk Power Systems, an Indian firm, uses second-world
war-era diesel generators fitted-
With biomass
gasifiers that can use rice husks, which are otherwise left to rot, as a
feedstock. Wires are strung on cheap, easy-to-repair bamboo poles to
provide power to around 600 families for each generator.
