| environ. | fornybar energikilde | renewable energy source Energy sources that do not rely on fuels of which there are only finite stocks. The most widely used renewable source is hydroelectric power; other renewable sources are biomass energy, solar energy, tidal energy, wave energy, and wind energy; biomass energy does not avoid the danger of the greenhouse effect |
| environ. | fornybar ressurs | renewable resource Resources capable of being continuously renewed or replaced through such processes as organic reproduction and cultivation such as those practiced in agriculture, animal husbandry, forestry and fisheries |
| environ. | fornybart råstoff | renewable raw material Resources that have a natural rate of availability and yield a continual flow of services which may be consumed in any time period without endangering future consumption possibilities as long as current use does not exceed net renewal during the period under consideration |
| environ. | ikke-fornybar energikilde | non-renewable energy resource Non-renewable resources have been built up or evolved over a geological time-span and cannot be used without depleting the stock and raising questions of ultimate exhaustibility, since their rate of formation is so slow as to be meaningless in terms of the human life-span |
| environ. | ikke-fornybar ressurs | non-renewable resource A natural resource which, in terms of human time scales, is contained within the Earth in a fixed quantity and therefore can be used once only in the foreseeable future (although it may be recycled after its first use). This includes the fossil fuels and is extended to include mineral resources and sometimes ground water, although water and many minerals are renewed eventually |
