An Indian social business that leads Himalayan treks to set up solar micro-grids in remote mountain villages plans to expand its clean-energy work to other countries facing similar challenges, after winning a United Nations climate award.

Global Himalayan Expedition (GHE) has brought solar electricity to more than 130 Indian villages, benefiting about 60,000 people, while setting up home-stays for tourists that have generated more than $100,000 in income for villagers.
