The enterprise involved in converting raw materials into good and useful products, and the services that go toward delivering those products to the ultimate user, are for the most part powered by the energy extracted from natural gas, petroleum, and coal, all very concentrated forms of stored energy. There are other limited degrees of energy extracted from other sources, but that contribution is at best marginal and sometimes quite uncertain.
This conversion of energy to products and services, creates the true source of wealth and prosperity. The equation is as simple as that.
