| el. | a source of electrical power in which the energy liberated in radioactive decay is collected as heat and converted,usually directly by thermocouple action,into electricity | termoelektrisk radioisotopgenerator |
| energ.ind. | alternative energy source | alternativ energikälla |
| commun., el. | dynamic source of energy | dynamisk energikälla |
| environ. | energy source Potential supplies of energy including fossil and nuclear fuels as well as solar, water, wind, tidal and geothermal power | energikälla |
| environ. | energy source material | energikällmaterial |
| environ. | energy source material Sources from which energy can be obtained to provide heat, light, and power. Energy resources, including fossil and nuclear fuels as well as solar, water, tidal and geothermal energy, may be captured or recovered and converted into other energy forms for a variety of household, commercial, transportation, and industrial applications | energikällmaterial |
| energ.ind. | energy source material | energikälla |
| environ., energ.ind. | low-carbon energy source | energikälla med låg åtgång på fossila bränslen |
| environ. | non-polluting energy source Energy that is ecologically safe and renewable. The most widely used source is hydroelectric power, which currently supplies some 6.6% of the world's energy needs. Other non-polluting sources are solar energy, tidal energy, wave energy and wind energy. Most non-polluting energy sources require a high capital investment but have low running costs | icke-förorenande energikälla |
| energ.ind. | non-renewable energy source | icke-förnybar energikälla |
| energ.ind. | primary energy source | primär energikälla |
| environ. | 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 | förnyelsebar energikälla |
| nat.sc. | renewable energy source contribution | förnybara energikällors bidrag |
| nat.sc. | renewable energy source contribution | bidrag från förnybara energikällor |
| stat., el. | source energy | totalt levererad energi inklusive förluster |
| energ.ind. | source of energy | energikälla |
| environ. | use of waste as energy source | återanvändning för produktion av energi |
