Peru recently announced a programme to supply solar power to two million of its six million people without access to electricity. The emphasis will be on poor rural areas, and the solar programme will contribute to the overall target of providing electricity to 95 per cent of Peru's population of 30 million by 2016, up from 66 per cent now. 
The World Bank considers Peru to be "a country committed to poverty reduction and shared prosperity",  but there is a major gap between urban and rural poverty rates — 18 and 56 per cent respectively. 
“Ambitious leadership and realistic financing plans make solar a genuine alternative for villages in hard-to-reach development contexts.”
The new National Photovoltaic Household Electrification Programme is partly a response to an International Finance Corporation report in 2011 that concluded that less than one per cent of the country's possible solar power resources were being exploited . However, the national regulatory framework was updated to encourage use of renewable energy in the same year. 
In addition, there clearly is support at the top for the new drive, as Jorge Merino, the energy and mining minister, has featured prominently in the programme's launch and subsequent publicity.
My awareness of the potential for solar energy to reach poor communities with little prospect of being connected to the grid was heightened some years ago when I met Dipal Barua, one of the founders of Grameen Bank, who has since branched out into an ambitious programme to make Bangladesh one of the first solar nations.
His vision is to provide solar power to rural families at no more than the cost of the kerosene that they would otherwise use for power. 
Bangladesh now has a renewable energy association  and Barua has updated his presentation: he told an international 'off-grid' conference in Ghana last year that 1.5 million home solar installations have now been made in Bangladesh, benefiting 15 million people. 
Of course, one must be cautious in evaluating plans and promises. I have visited neither Peru nor Bangladesh, so am unable to assess the reality of these programmes. But these two stories suggest that ambitious leadership and realistic financing plans make solar a genuine alternative for villages in hard-to-reach development contexts.
