The world is changing, and so are the ways in which we power it. Already there are several nations that get more energy from renewable energy sources, or have had recent stretches where the majority of their energy output was from low carbon sources. Recently the U.K. has joined that list by having 50.2 percent of their energy delivered by low emission sources, including natural gas, nuclear, wind, and solar, and that trend is only going to continue and get larger and larger in the future, especially as the government has announced plans that would see coal fueled power plants close by 2025.
Between July and September the U.K. saw just over half of its energy come from these low emission sources. While many start the push towards more renewable energy, coal is being displaced by cheaper and more efficient natural gas. Natural gas power plants are cheaper to maintain, produce fewer carbon emissions, and can be run on methane from more sustainable sources in the future which can give them a longer operating span than the dirtier and more obsolete coal systems that were previously more popular. Many investors in energy companies are demanding lower emissions and more renewable sources, which will continue to drive the trend even if regulations on carbon are reduced in the future.
