International Development Enterprises, India

The winners of the world's leading green energy awards were announced last night, all of them demonstrating a commitment to address climate change and bring social and economic benefits that radically improve people's lives. This year, the Outstanding Achievement Award went to International Development Enterprises, India. IDEI won an Ashden Award in 2006 for their treadle pump that farmers use to lift water to irrigate their crops, and lift their families out of poverty and is now scaling up. IDEI hopes that nearly two million pumps will have been sold by 2020.
