The Surprising Success of Micro Hydro

A follow-up article on Husk Power Systems, which has created a scalable system to turn rice husks into electricity that is reliable, eco-friendly and affordable for families in India. The company bases their business model around local involvement, grassroots systems that cater to the immediate community, and continual accountability. This article fills in some information gaps from the initial piece, "Fixes: A Light in India."

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.

Micro-hydro projects in the United States have become much more accessible and more financially viable since Congress passed a law in 2013 making it easier for small hydroelectric projects to get federal approval. Specifically, water treatment plants that can retrofit their systems to generate electricity are an excellent energy opportunity. The plant in Grand Lake now produces more electricity than it consumes.

The rapid development of emerging economies across Asia and Africa is lifting hundreds of millions of people out of poverty - but there is much debate as to how to best structure this growth. If these economies evolve in the same way as in the West - with unchecked, excessive resource consumption and heavy pollution - the planet may be on the fast track to disaster. Earthrise explores how these nations can grow sustainably using improved, eco-conscious technologies like renewable energy and eco-friendly farming practices.

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.

In Zanzibar, hundreds of households too poor and remote to have access to the electrical grid are getting low cost solar power for the first time, from a group of local female engineers trained by and Indian NGO. It's the first of several "solar mamas" projects planned for parts of rural Africa, and it's turning some traditional gender roles on their head.

The commercially-based Wind for Prosperity initiative may have devised a solution to meet growing demands for electricity in developing economies, where fossil fuels are expensive, difficult to access, and take a toll on environmental and human health. The venture works to refurbish wind turbines from Europe and re-deploy them in the developing world, providing clean and affordable power where it’s needed most.

Three women have embraced the use of solar technology to become clean energy entrepreneurs. They are helping bring light, efficient cookstoves, and energy to their communities, while reducing carbon emissions and empowering other women along the way.

A bright young man named William took it upon himself to bring electricity to his small, rural village in Malawi, despite having few resources at his disposal. William invented a windmill using recycled materials, and successfully generated power for his home. His incredible ingenuity attracted international attention, inspiring others as far away as Portsmouth University to design windmills that are financially and physically accessible for the world's rural poor living off the grid.

Abel Cruz "catches" clouds on his fog net farm to help provide free water for his community in a slum on the outskirts of Lima, where access to water is very limited and costly. While this solution may never compete with large scale and traditional technologies, many argue there is enormous potential for this simple concept in certain, rural areas of the world.
