The sources to alleviate the energy situation in the world are sufficient to supply all foreseeable needs. Conservation of energy and rationing in some form will however have to be practised by most countries to reduce oil imports and redress balance of payments positions. Meanwhile development and application of nuclear power and some of the traditional solar wind and water energy alternatives must be set in hand to supplement what remains of the fossil fuels. The encouragement of greater energy use is an essential component of development. In the short-term it requires mechanisms to enable the rapid increase in energy capita and in the long-term we should be working towards a way of life which makes use of energy efficiency and without the impairment of the environment or of causing safety problems. Such a programme should as far as possible be based on renewable energy resources. Large-scale conventional power plant such as hydropower has an important part to play in development. It does not however provide a complete solution. There is an important complementary role for the greater use of small-scale rural based power plant. Such plant can be used to assist development since it can be made locally using local resources enabling a rapid built-up in total equipment to be made without a corresponding and unacceptably large demand on central funds. Renewable resources are particularly suitable for providing the energy for such equipment and its use is also compatible with the longterm aims. It is possible with relatively simple flat plate solar collectors Figure 1 to provide warmed water and enable some space heating for homes and offices which is particularly useful when the buildings are well insulated and thermal capacity sufficient for the carry over of energy from day to night
