6.2. Non-Power Renewable Energy Options
Renewable energy can also be used in heating applications, for transportation fuels and, in the case of biofuels, as a feedstock for synthetic organic materials, such as plastics. In the heating sector, low temperature building applications and higher temperature industrial applications can be discerned. Residential applications include hot water and heating. Heating is only needed in parts of Africa. Energy-efficient building design should be a priority. South Africa has started a large-scale solar water-heating programme. This could be expanded to other parts of the continent. Solar building heating requires a more fundamental change in building design. Solar cooling is still in a demonstration stage and not high priority for the coming five years.
