Exactly, we haven't achieved that much actually. Most of the technology we use for harvesting energy is not much further from what people could imagine in 19th century. Turbine was invented in the 19th century. I really suggest watching this talk by Smil https://www.youtube.com/watch?v=5guXaWwQpe4 https://www.youtube.com/watch?v=5guXaWwQpe4 and if you are interested reading some books from him about energy and oil. Really insightful.
