Africa's Future is Clean Energy

Grassroots organizations, Empowered by Light and Empower Generation, are killing two birds with one stone: bringing clean energy to rural Nepal, and creating jobs for Nepalese women in the environmental sector. By helping to install electricity-generating solar panels, which simultaneously prevents illegal animal poaching, women are provided not only with a stable income and a ladder to reliable economic growth, but also with a rich work-life balance, allowing them to become “clean energy entrepreneurs” while continuing to care for their families and tend to their village’s needs.

Watergate Estate is working on two issues in South Africa: affordable housing and renewable energy. The housing development is installing solar panels for its residents that are being bought by people all over the world using cash or bitcoin as a way to offset their own carbon costs. Not everyone agrees that gated communities like this are helping to fight social inequalities, crime, and unemployment, but about 470 people bought solar cells for the apartment complex and some residents say they feel safer in their community.

One of the greatest challenges to integrating renewable energy sources into the power grid has been the issue of storage - where and how to keep power generated during off-hours (such as overnight) when demand is low. While batteries are on the rise as one solution, an Alabama power plant has discovered a natural way of storing energy until it is needed: pumping air into salt caverns.

The United Kingdom is finding creative ways to simultaneously address renewable energy needs and waste disposal. Combined Heat and Power (CHP) plants are utilizing chicken manure from farms and coffee grounds to create electricity. The initiatives have the added benefit of improving standards for the treatment of poultry, as well as reducing the distribution of harmful toxins from the waste.

An economic shift to renewable energy could take decades, but thanks to rapidly evolving disruptive technologies, dropping prices of solar and wind power sources, and increasing market demand for green business, the new age of renewable energy could encompass the world economy much more quickly.

A local energy cooperative in Colorado, Delta Montrose Electric Association, is spurring economic development through renewable energy. The program has allowed Delta County to diversify energy sources, and has become a tool for economic revitalization.

A new solar array called North Star in the Twin Cities will soon produce enough energy to power more than 20,000 homes. The project allows landowners to evolve beyond a deteriorating farming industry while maintaining native prairie plants under and around the panels for bees and other pollinators. The project is part of the state's 15-year energy plan to reduce carbon emissions by 60 percent and generate a third of its electricity from renewable sources by 2030.

The Hydropower Empowerment Network takes a country-by-country approach to helping establish micro hydro and other technologies in rural places where electricity is difficult to come by. Micro hydro has even proven to be more durable and sustainable than solar, though solar is cheaper and quicker to install - the reason is the depth of community involvement required. When villagers participate on longer-term, complex projects, they develop pride in their work, learn invaluable new skills, and are empowered to engage with the solution.

Researchers at the University of Minnesota's West Central Research and Outreach Center are looking for ways to make producing dairy milk less energy intensive - something consumers are increasingly demanding. They have had some initial success in increasing efficiency using techniques such as capturing heat from the milk to heat water and experimenting with solar and wind to offset some electricity use.

Rahr Malting, a brewery in Shakopee, MN, has found a creative way to sustainably address their energy needs. The company partners with the Mdewakanton Sioux Community to use waste barley hulls from the malting factory to generate electricity for their facilities, selling excess power to the public grid while the waste heat sprouts the malt to make beer.
