On Ember analysis showing the latest fall in solar-storage costs:
“Falling battery prices means it is now viable to convert daytime solar into reliable round-the-clock electricity. The energy transition’s power duo of solar and batteries is quickly demolishing the old argument that we’ll always need fossil fuels to plug the gap.
With even cheaper storage on the horizon and renewables fast to build, 24/7 carbon-free electricity will become the first choice for businesses looking to achieve energy security.”
Sam Kimmins, Director of Energy at Climate Group
