Energiesprong wants every home to be net-zero

Apartments at Front Flats, a new residential building in Philadelphia, is powered by 492 solar panels that are wrapped around the building. The point: to demonstrate that developers can design buildings that are energy-efficient and be built at an affordable cost. It’s not clear yet if the building is “net zero” in terms of producing as much energy as it consumes, but residents are paying only $40 a month for utilities.

An apartment complex in Utah includes a solar battery in every apartment allowing the resident, power utility, and building developer to save costs for generating electricity. Through a unique partnership, the power systems can provide 12.6 megawatts of power for the building, which translates into residents saving up to 40 percent on the energy bills. This setup might not be easy to scale, but the developer plans to expand the model in other states.

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 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 city of River Falls in Wisconsin built the state’s first city-owned solar garden, taking steps to reduce their use of fossil fuels and encourage community members to go green. Now, all city buildings are 100 percent run on renewable energy and residents can sign up for a program allowing them to buy renewable energy. Getting people to take action can be difficult, but city officials say they found the right message to get its residents on board.

Mosques across Amman, Jordan are adorned with solar panels, resulting in some very energy efficient places of worship (along with many other buildings). The mosques now cover 100% of their energy needs and can even sell excess energy back to the national grid. The city is aiming to become carbon neutral by 2050, and in addition to recycling, environmental education, and solar water heaters, Amman is expanding their ecotourism industry to attract more environmentally conscious tourists.

Dams make for complex and often controversial infrastructure. While hydropower generated from large dam projects is currently providing the bulk of the planet's renewable energy, dams can also cause major environmental and social damage by interrupting animal migrations, displacing indigenous communities, and collecting toxins. A number of solutions are being implemented, however, to address the various issues caused by dams, to help make them a more eco-friendly and viable source of clean energy.

Solar energy is a clean, cheap, renewable, and land-efficient resource, making it a valuable technology to scale up in the face of climate concerns and clean energy. Diversifying the supply chain for creating and sourcing solar panels can help make solar energy more reliable when faced with geopolitical and human rights issues.

After the 2008 economic recession hit, Carla Walker-Miller shifted her energy services business model to not only supply electrical equipment but also implement energy efficiency programs for communities of color in Detroit. She has been able to service 75 households, which has resulted in energy bill savings up to $600 a year for families. The company also has a robust recruitment and training program for young people and those experiencing economic hardship.

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.
