You'd be surprised. For instance there are windmills today that produce enough electricity for one average home for one day with only one revolution of a propeller. And while you are dismissing non fossil fuel energy, UK and are some other countries are going completely green in few years.
teachings of the Bible are so muddled and self-contradictory that it was possible for Christians to happily burn heretics alive for five long centuries. It was even possible for the most venerated patriarchs of the Church, like St. Augustine and St. Thomas Aquinas, to conclude that heretics should be tortured (Augustine) or killed outright (Aquinas). Martin Luther and John Calvin advocated the wholesale murder of heretics, apostates, Jews, and witches. - Sam Harris, "Letter To A Christian Nation"
