Off-grid electricity can be defined as a stand-alone power system or mini-grid to typically provide a small community with electricity without the support […]

Can we supply 100% of our energy needs from renewable sources?

Is there enough space for all the wind turbines and solar panels to provide all our energy needs?  What happens when the sun doesn’t shine and the wind doesn’t blow?  Won’t renewables destabilise the grid and cause blackouts? In a review paper published in the high-ranking journal Renewable and Sustainable Energy Reviews last year, Benjamin […]
