Artan k\u00fcresel enerji talebiyle birlikte, fosil enerji, \u00f6zellikle petrol, k\u00f6m\u00fcr ve do\u011fal gaz, sonunda t\u00fckenecektir. Ayr\u0131ca, fosil enerji kullan\u0131m\u0131 s\u0131ras\u0131nda ciddi \u00e7evre kirlili\u011fine de neden olacakt\u0131r.

G\u00fcne\u015f enerjisinden yararlanman\u0131n temel yolu fotovoltaik g\u00fc\u00e7 \u00fcretimidir.
