What Is the Future of America's Greenest Town?

A wastewater treatment plant in Oregon not only cleans water that is released into the local river, but it also creates fertilizer that is sent to farmers to use on non-food crops and it produces renewable power from methane. The green energy created at the plant heats five buildings on the site and produces half of the energy the facility uses. This kind of co-generation system is growing in other places in the United States, China, Brazil, and Norway.

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.

Solar power panels are broadly supported across America, as concern about climate change increases; however, not all supporters want solar power plants in their backyard. Now, companies and local governments work to install these renewable energy sources while informing neighbors and stakeholders of the benefits of these plants.

After Hurricane Maria hit Puerto Rico, knocking out power across the country, solar energy has stepped in to be a sustainable possibility. Such efforts have included lobbying local legislatures to incentivize communities to create their own solar project and training residents to install solar panels on their own. Many of the solar initiatives that have started have been community-led and hyper-local, meaning that what many deem a basic right – access to energy and electricity – are more accessible than ever.

A community in North Amsterdam tackles the issue of rising water levels head on by building homes that can float. The houses are built to include solar energy grids using blockchain so neighbors can share electricity, and the structures rise and fall with the ebbs and flows of flooding.

Repurposing contaminated sites for clean energy production may not sound like a common tactic to take, but Massachusetts has found a way to be highly successful at it. In fact, out of over 250 renewable energy installations across the United States, Massachusetts accounts for 40 percent of them. The state attributes this success to a combination of an enhanced ease of the bureaucratic process and opportunities for revenue stimulation for towns.

From solar to geothermal to biomass projects, First Nations are finding ways to confront and combat fossil fuel concerns head on. In fact, over 30 Nations have some type of renewable energy source powering their communities, while 15 more have projects underway. Despite a lack of governmental funding assistance, First Nations are acting as a collective model for how communities can provide their own clean power to their own people.

A collaborative effort among the United Nations' District Energy in Cities Initiative, the Malaysian government, and private partners has facilitated planning in Malaysia's rapidly developing southern state of Johor for a "District Energy System": a single heating and cooling network which decreases energy consumption by converting waste heat from large power stations. Because of this intervention, Iskandar is projected to decrease its energy use by almost 40% -- all while saving money on energy costs, recycling heat energy, and contributing to the nation's goals under the international Paris Accord.

Burlington, Vermont counts itself as America's first all-renewable city, satisfying its energy needs through a combination of sustainably harvested pine and timber wood chips, hydroelectricity, four wind turbines, and a solar panel array near the local airport. Aside from the environmental benefit of renewable energy, the city has seen other benefits in the form of cheaper energy costs and healthy, locally-grown food.

Around the globe, countries have taken actions that have helped reduce carbon emissions and increase the use of renewable energy. Although the state of Florida feels the effects of climate change, its state representatives have not produced policy addressing it. Local policy makers and organizers have made the biggest difference in the state.
