En el cas de la llum, existeix la tarifa TUR (tarifa d'últim recurs) sense discriminació horària, la TUR amb discriminació horària (té en compte el consum d'energia en hores punta i vall) i el bono social. Alternativament es pot acudir al mercat lliure de l'energia elèctrica, que pot tenir un preu inferior al de la TUR.</span></span><br />

Es basa en la tecnologia de les cèl·lules fotoelèctriques que aprofiten l'<span style="font-style: italic; font-weight: bold;">efecte fotovoltaic</span> (que transforma l'energia dels fotons de la llum en corrent elèctric directament) mitjançant materials semiconductors com el silici (Si).

<span style="font-family: Georgia,"Times New Roman",serif;"><br /></span>
<span style="font-family: Georgia,"Times New Roman",serif;">A la web de REE es pot observar què és i com funciona el CECOEL ("centro de control de la energía eléctrica").</span><br />
<span style="font-family: Georgia,"Times New Roman",serif;"><br /></span>
<span style="font-family: Georgia,"Times New Roman",serif;">El camí que recorre l'energia elèctrica des de que es genera fins que es consumeix s'observa als esquemes següents (<span style="font-style: italic;">extrets de consumer-eroski i de la web de REE, respectivament</span>).</span><br />
