The photos gives you some idea of the scale of what is involved. From the report:
The South African government has set a target of 10,000GWh of energy to be produced from renewable energy sources (mainly from biomass, wind, solar and small-scale hydro) by 2013. This would be equivalent to electrifying approximately 2 million households having an annual electricity consumption of 5 000 kWh. That is about 5% of the present electricity generation in South Africa, or replacing two 660MW units of Eskom's combined coal-fired power stations.
There is only about 1.8 million households in Ireland at present. So 5% of South Africa's electricity consumption could serve Ireland quite nicely. So the scale of the renewable energy roll out in larger countries must be very audacious indeed. The mind boggles doesn't it?
