The Milken Institute and the Motsepe Foundation have announced Aftrak and Omnivat as winners of the Milken-Motsepe Prize in Green Energy – a $2-million innovation competition to reward entrepreneurs working to expand access to reliable, affordable and sustainable offgrid electricity in Africa. Aftrak, an initiative based out of the UK and Malawi, was awarded the $1-million grand prize for its easily assembled solar microgrid and custom-designed tractors, which have tripled agricultural yield, increased farmer incomes and provided electricity to remote communities.
