How has the mix of energy sources changed in the last 50 years?

Over the last 50 years, while energy consumption grew substantially, the world undertook a transition in its usage of fossil fuels, from solids (coal) to liquids (oil) to gases (natural gas). … Meanwhile, the share of oil declined as well, from 40% of energy consumption in 1965 to 33% in 2016.

How has energy sources changed over time?

The types of energy used in the United States have changed over time. The change has been driven by advances in technology, energy resource discoveries, energy prices, social pressures and other factors. The only constant is that the amount of energy used has increased steadily over time.

How has the UK’s energy mix changed over time?

The major change in the make-up of UK energy consumption is the rapid decline in the use of coal and fuels made from it, such as coke and blast furnace gas. The void left by the fall in coal use has been filled largely by a rapid rise in the use of natural gas and, to a lesser extent, an increase in electricity usage.
