Logika stojaca za t\u00fdmto nev\u0161edn\u00fdm nadpisom je v skuto\u010dnosti pomerne jednoduch\u00e1: Aby ste mohli pou\u017e\u00edva\u0165 ak\u00fdko\u013evek po\u010d\u00edta\u010dov\u00fd program, prehliada\u0165 internet, pou\u017e\u00edva\u0165 mobiln\u00fa aplik\u00e1ciu, potrebujete k nim energiu.
