Kenya harnesses geothermal energy to power the nation. By developing naturally occurring geothermal areas at the East African Rift, they were able to supply almost half of the country's energy needs in 2015.

Samsø, a small island in Denmark, has done what no other city has reached; energy independence. People on the island use a combination of wind, solar, and biomass, energy. How is such a large feat accomplished? Local leaders say it wasn’t because of technological breakthrough, but through collective action.

Setting the bar high for environmental sustainability can encourage innovation and experimentation. Developers of Paris’ new Clichy-Batignolles eco-district are reducing the neighborhood’s carbon footprint in nearly every way imaginable. Solar panels and vegetation cover the energy-efficient buildings, the water table under the 10-hectare (25-acre) park provides geothermal heating, deliveries are directed to a central drop-off site, and much more.

An indigenous-led nonprofit group called Tonibung installed a micro-hydro electrical system for a village deep in Borneo’s rainforests. The project not only supplied much-needed energy for the villagers of Kampung Buayan, but it is also protecting the surrounding ecosystems, creating jobs for people, and encouraging youth to get involved. “We want to advocate for native rights to self-determination and empower indigenous groups to choose the kind of development that meets the aspirations of their people,” says the founder of the organization.

Covering canals with solar panels has allowed Indian communities to save land, water and carbon emissions, and even bring electricity to rural villages. The solar panels are suspended on metal structures over the canal, which can generate electricity for farmers and be fed into the state grid or sold to public utilities. While these canal-top solar power plants can be expensive to build, so far, eight Indian states have commissioned canal solar projects.
