In this world where we seem surrounded by news of gloom and doom, we don't often hear stories of positive change.

But here is one: a story of a village that has unshackled itself from darkness, after 30 years of having its energy needs neglected by governments.

Today, Dharnai is blooming with hope and ambition.

Dharnai village in Bihar, one of India's poorest states, is now lit-up by a Greenpeace India solar-powered micro-grid. 

Enter the village and you'll see electric poles all around. The solar micro-grid supplies the electricity for homes, street lighting for roads and lanes, and water pumps.
