Introduction partielle
The majority of the rural population and the urban poor in Developing Countries (DCs) are likely to remain heavily dependent on traditional biomass to meet daily energy needs for cooking, and kerosene for lighting, in decades to come. The reasons for this is the lack of affordable (costs), available (distribution) and acceptable (traditionally and culturally) alternatives. Rural Electrification Programmes (REPs) in these countries are often poorly implemented and would not even have a great impact as electricity is commonly not used for cooking due to high tariffs and cultural preferences. Renewable energy projects are still too expensive with heavy reliance on external technologies/expertise and often lack acceptance by rural communities. Hence they are in most cases not suitable for wider distribution unless profoundly subsidised by government and/or donors. Energy efficiency projects (e.g. energy saving stoves) which are predominantly used in urban households do have a positive short-term impact on household expenditure and the preservation of natural resources. The expected increase in population size is however believed to outpace the sustainable supply of biomass hence tremendously increasing the pressure on natural resources (e.g. forests).
