An estimated 1.5 billion people in developing countries have no access to electricity, with more than 80 per cent of these living in sub-Saharan Africa or South Asia. [1]
The problem is most acute in remote areas: 89 per cent of people in rural sub-Saharan Africa live without electricity, which is more than twice the proportion (46 per cent) in urban areas. [1]
For these people, even access to a small amount of electricity could lead to life-saving improvements in agricultural productivity, health, education, communications and access to clean water.
Options for expanding access to electricity in developing countries tend to focus on increasing centralised energy from fossil fuels such as oil, gas and coal, by expanding grid electricity. But this approach has little benefit for the rural poor. Grid extension in these areas is either impractical or too expensive.
Neither does this strategy help tackle climate change. Power already accounts for 26 per cent of global greenhouse gas emissions and while most of this comes from the developed world, by 2030 developing countries are predicted to use 70 per cent more total annual energy than developed nations.[2]
There is therefore a clear need for pro-poor, low-carbon ways to improve access to electricity in the developing world — solar power could be one such solution.
Place in the sun
The Earth receives more solar energy in one hour than the world population consumes in an entire year.
Almost all developing countries have enormous solar power potential — most of Africa, for example, has around 325 days of strong sunlight a year, delivering, on average, more than 6 kWh energy per square metre a day (see Figure 1).
The Desertec Foundation, a joint German and Jordanian company, estimates that covering just one per cent of global deserts in solar panels could power the whole world. [3]

Solar power , like bio fuels could be dangerous to the power monopolies . THEY want to be in control . Solar panels on , your home ? , well , that is just too darn empowering to the individual . People might get to think they were , important , or something . Sarcasm , aside , Jan , It is Glaringly obvious , this needs to be done , it is the right thing . Profitable in the long term , for us and our children and the global village were are part of . Profitable for the earth and long term biodiversity , and our greater understanding of it . Yes corporate profits would go down for a decade , until they either switched to solar manufacture or adapt in some other way . If you like say , decent food , peaceful surroundings ( war can be fun in a video game , but REAL ? 24/7 ? ) , clean air - this is the way to go .

Harnessing solar power in Africa for those who live in Africa. What a concept, eh? But what do certain rich people in this world want to do? Harness it for Europe while building toxic nuclear plants in the developing world. Nothing philanthropic about that.
