Mozambique is seeking to use renewable energy to extend electricity access to rural institutions. Joshua Kirshner

Mozambique needs a community-driven approach to electrification

Mozambique has long standing energy challenges and widespread energy poverty. To change this, particularly for people living in rural areas, it needs to democratise the way it supplies energy.

Affordable batteries for green energy are closer than we think

At the heart of the current debate around energy is the question of storage. In cars, how to build batteries that run for hundreds of kilometres; in electricity, storing energy from solar panels for when…
