Comparações emaranhadas: energias renováveis versus combustíveis fósseis
Por Norman Rogers via RealClearEnergy .
Muitas vezes nos dizem que a energia eólica e solar, se não mais baratas, são pelo menos competitivas em termos de custo com combustíveis fósseis. Completamente errado! A energia eólica ou solar custa cerca de cinco vezes mais por megawatt-hora em comparação com, por exemplo, o gás natural.

It may seem difficult at first, but everything is difficult at first.
