Nearly 370 million people in the HKH region do not have access to electricity, with close to 1.8 billion people relying on traditional, polluting biomass fuels for energy. Renewable Energy and Energy Efficiency Capability for the Hindu Kush Himalaya (REEECH) is the first centre with a mountain focus that functions as a regional hub and think tank under the Global Network of Regional Sustainable Energy Centres (GN-SEC) to accelerate universal energy access in the HKH region and place mountain energy issues on the global sustainable development and climate agenda.
