Fossiilsed energiaallikad seevastu on piiratud v\u00f5i vajavad miljoneid aastaid, enne kui nad uuesti k\u00e4ttesaadavaks muutuvad. Fossiilsete k\u00fctuste, nagu kivis\u00fcsi, nafta ja maagaas, kasutamine p\u00f5hjustab suure osa kasvuhoonegaaside heitkogustest ja seega ka globaalset soojenemist. Taastuvate energiaallikate kasutamise laiendamine t\u00e4hendab seega kliimakaitse.   <\/p>\n\n<p class=\"wp-block-paragraph\">Julgustav fakt: Maale paistev p\u00e4ikeseenergia katab inimese praeguse energiavajaduse mitu tuhat korda. Teisis\u00f5nu, innovatsiooni ja leidlikkuse abil v\u00f5ime leida tehnilisi v\u00f5imalusi selle peaaegu ammendamatu reservuaari kasutamiseks. Veel \u00fcks julgustav m\u00e4rk: 2022. aasta l\u00f5pus teatas USA l\u00e4bimurdest tuumas\u00fcnteesi, potentsiaalse tuleviku energiaallikana. Esimest korda on aatomituumade termotuumas\u00fcnteesi k\u00e4igus toodetud rohkem energiat kui tarbitud.   <\/p>\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"105\" height=\"99\" src=\"https:\/\/sw.fst.com\/magazine\/wp-content\/uploads\/2023\/03\/fst-sw-2023_2-1200sq_0006_Earth.png\" alt=\"\" class=\"wp-image-6566\" srcset=\"https:\/\/sw.fst.com\/magazine\/wp-content\/uploads\/2023\/03\/fst-sw-2023_2-1200sq_0006_Earth.png 105w, https:\/\/sw.fst.com\/magazine\/wp-content\/uploads\/2023\/03\/fst-sw-2023_2-1200sq_0006_Earth-90x85.png 90w\" sizes=\"auto, (max-width: 105px) 100vw, 105px\" \/><\/figure>\n\n<h2 id=\"maa\" class=\"wp-block-heading\">Maa<\/h2>\n\n<p class=\"wp-block-paragraph\">Biomassi saab kasutada energia tootmiseks mitmel erineval viisil.

Siiski ei saa neid siis enam toiduks kasutada. Biogaasi tootmiseks saab kasutada rohelisi j\u00e4\u00e4tmeid, kompostitavaid j\u00e4\u00e4tmeid, vedels\u00f5nnikut ja reoveesetteid.

See saavutatakse elektriliste soojuspumpade t\u00e4iendava kasutamisega. Seda ei ole vaja s\u00fcgavama geotermilise energia puhul, mis tungib mitme kilomeetri s\u00fcgavusele maa sisse. Seda kasutatakse mitte ainult k\u00fctmiseks, vaid ka elektrienergia tootmiseks.
