Os combustíveis fósseis são resultado de um processo de decomposição das plantas e dos animais.Uma grande variedade de fontes de energia, sobretudo as que dizem respeito aos combustíveis fósseis (carvão, petróleo e gás natural), faz parte dos recursos energéticos que dispomos.
Consequências da utilização de combustíveis fósseis- Como não são recursos inesgotáveis, uma das principais preocupações está relacionada com o possível esgotamento das jazidas.Os combustíveis fósseis demoram dois milhões de anos para se formarem. Actualmente os humanos gastam desmesuradamente recursos que se formaram á mais de 65 milhões de anos no tempo dos dinossauros. Uma vez esgotados não é possível fabricá-los e temos que esperar muito tempo para voltarem a existir. Assim, é melhor preservá-los e poupá-los antes que esgotem. Eles não se renovam nem se fabricam
- Outro aspecto, não menos importante, está relacionado com o impacte ambiental, sobretudo no que diz respeito a fenómenos de poluição em várias vertentes.
