It can be argued that the Industrial Revolution began in the British Isles, largely because of the availability of coal. It can also be argued that burning coal in such great quantities was the beginning of our current pollution problem. As of April 21, The UK has shifted its energy production to the point that no coal was burned for the grid. Fossil fuels continue to dominate at over 40% because of natural gas. Nuclear is just above 20%. Renewable energies like wind (>10%) and solar (<10%) are small, but rising. Coal will continue to be needed for peak winter loads, but this is a milestone in the cycle of history that was the Industrial Revolution.
