Meet the South Korean entrepreneurs promising a clean energy revolution

Decades after South Korea's stark economic past, its startups are developing solar, wind and hydro-powered products for developing world markets

For South Korean millennials born into bright lights, cheap energy and bustling modernisation, the country's dimly lit, war torn past is a thing of the history books. This made Akas Kim's trip to rural India, seeing remote villages struggling to secure running water and power, all the more shocking for him. He was determined to make a difference.

On his return to South Korea, he invested 10m won (5,860) of his own money into founding Energy Farm, which teaches communities in developing countries across Asia and sub-Saharan Africa - including Tanzania and Myanmar - how to make their own wind turbines, solar-powered cookers and power-generating bicycles.
