However, petroleum, like coal and natural gas, is a nonrenewable source of energy. It took millions of years for it to form, and when it is extracted and consumed, there is no way for us to replace it. …
But with the Industrial Revolution came the rise of coal; followed by oil, gas; and hydropower by the turn of the 20th century. It wasn't until the 1960s that nuclear energy was added to the mix. What is often referred to as 'modern renewables' – solar and wind – were only added much later, in the 1980s.
