The International Energy Agency projects that renewables will account for half of global power generation by 2030 and will continue to progress faster in the decades following. Here are some of the many reasons why. Firstly, major improvements to the electricity transmission system now allow weather-driven renewable resources like solar energy to be transmitted from a place where the sun is shining across the country to a place where it isn’t. High accuracy wind and solar availability forecasts also allow for electricity operators to prepare for weather 24 to 36 hours in advance, allowing operators to arrange where they will get their power from before certain arrives to that area. Prices of electricity storage batteries are also dropping increasingly and the capacity of pumped storage, the most used way to store electricity, is expected to be multiplied by a factor of 3 to 5 by 2050. Hyper-efficient solar thermal electric power plants are also gaining traction in the sunnier places of the world and with government policies created to support renewable energy, it seems there is no stopping the renewable energy revolution.
