 Tepeln\u00e9 elektr\u00e1rny
 I kdy\u017e jsou dnes tepeln\u00e9 elektr\u00e1rny ji\u017e sv\u00fdm zp\u016fsobem zastaral\u00e9, pod\u00edvejme se na jejich vyu\u017eit\u00ed p\u00e1ry. V tepeln\u00e9 elektr\u00e1rn\u011b elekt\u0159ina vznik\u00e1 t\u00edmto postupem:
 
 \u00b7 spalov\u00e1n\u00ed uhl\u00ed,
 \u00b7 spalovan\u00e9 uhl\u00ed zah\u0159\u00edv\u00e1 vodu,
 \u00b7 voda se zah\u0159\u00e1t\u00edm zm\u011bn\u00ed v p\u00e1ru,
 \u00b7 p\u00e1ra pod tlakem rozt\u00e1\u010d\u00ed turb\u00edny.
 
 Turb\u00edna je tud\u00ed\u017e poh\u00e1n\u011bn\u00e1 p\u00e1rou, co\u017e se zas tolik neli\u0161\u00ed od postupu pou\u017e\u00edvan\u00e9ho u parn\u00edch stroj\u016f. A z\u00e1rove\u0148 to znamen\u00e1, \u017ee by se turb\u00edny nerozto\u010dily a t\u00edm p\u00e1dem by nevznikla elekt\u0159ina. \u0158ekli jsme, \u017ee je tepeln\u00e1 elektr\u00e1rna zastaral\u00e1. Tak se poj\u010fme pod\u00edvat na tu nov\u011bj\u0161\u00ed a nejd\u016fle\u017eit\u011bj\u0161\u00ed.
 
 Jadern\u00e9 elektr\u00e1rny
 I kdy\u017e se to na prvn\u00ed pohled nemus\u00ed zd\u00e1t, tak postup v jadern\u00e9 elektr\u00e1rn\u011b je velice podobn\u00fd tomu v elektr\u00e1rn\u011b tepeln\u00e9. Jak v\u0161ichni v\u00edme, jadern\u00e9 elektr\u00e1rny pracuj\u00ed s od\u0161t\u011bpov\u00e1n\u00edm t\u011b\u017ek\u00e9ho j\u00e1dra radioaktivn\u00edho uranu.
 
 To se \u0161t\u011bp\u00ed na mnoho leh\u010d\u00edch jader, b\u011bhem \u010deho\u017e se uvol\u0148uje energie. S touto energi\u00ed se ov\u0161em d\u011bl\u00e1 to sam\u00e9, co se spalovan\u00fdm uhl\u00edm. Zah\u0159\u00edv\u00e1 se d\u00edky n\u00ed voda, kter\u00e1 ji m\u011bn\u00ed v p\u00e1ru a ta n\u00e1sledn\u011b rozt\u00e1\u010d\u00ed turb\u00edny.
 
 To znamen\u00e1, \u017ee ob\u011b elektr\u00e1rny pou\u017e\u00edvaj\u00ed prakticky stejn\u00e9 principy jako parn\u00ed stroje, kter\u00e9 dnes najdete u\u017e jen v muzeu. I kdy\u017e se postupy vyu\u017eit\u00ed p\u00e1ry s \u010dasem postupn\u011b inovuj\u00ed a m\u011bn\u00ed, tak zbavit se jich by bylo \u0161ir\u00e9 \u0161\u00edlenstv\u00ed. D\u00edky p\u00e1\u0159e si toti\u017e m\u016f\u017eeme u\u017e\u00edvat ve\u0161ker\u00e9ho luxusu, kter\u00fd n\u00e1m elekt\u0159ina nab\u00edz\u00ed. N\u011bkdo by nam\u00edtl, \u017ee jsou zde st\u00e1le je\u0161t\u011b vodn\u00ed, fotovoltaick\u00e9 \u010di v\u011btrn\u00e9 elektr\u00e1rny, kter\u00e9 p\u00e1ru nevyu\u017e\u00edvaj\u00ed. Jen\u017ee tyto elektr\u00e1rny vyr\u00e1b\u00ed elektrickou energii velmi draze a nedok\u00e1\u017e\u00ed j\u00ed vyrobit takov\u00e9 mno\u017estv\u00ed, aby to pokrylo pot\u0159eby a po\u017eadavky n\u00e1s v\u0161ech.
