"The direction of travel is that both in the UK and globally we are already moving towards a low carbon economy," Martin added. "It is a clear message to any new government that they should prioritise making the UK a world leader in clean, green, technology."
"The first country to use coal for electricity is now on the cusp of being the first major economy completely phase it out,″ said Ben Caldecott, director of the sustainable finance program at the University of Oxford. "Doing so will improve air quality, reduce carbon emissions, and help attract investment into more reliable and secure alternatives."

"The change in how we produce energy is the industrial revolution of this generation: as the age of coal passes, the renewables boom is well under way,″ she said, according to SkyNews. "Coal has been part of the UK's past, but we should celebrate the move away from dirty and old fashioned technology to a modern, clean energy future."
