How does Islam teach Muslims to use energy prudently?

Summary

Islam requires energy to be used moderately and wisely, because humans are entrusted as khalifah to manage and preserve the earth. Wasting energy such as electricity, or consuming resources excessively, is prohibited by the sharia as it conflicts with the maqasid principle of preserving and cultivating the environment. Excessive stinginess that harms basic needs is also not praised, since moderation is what is required, as reflected in Surah al-Isra' verse 29. Prudent practices, such as reducing electricity waste and choosing renewable energy, form part of the trust owed to nature and future generations.
