  • How Philadelphia Has Tried to Address Water Debt

    An income-based payment structure has alleviated water debt in Philadelphia. Decreasing federal aid to municipal water utilities in conjunction with rising costs associated with climate change has increased the cost of water, making it unaffordable for many. Philadelphia created an income-based program, which caps water bills at three percent of income. The Tiered Assistance Program, or TAP, also provides debt elimination for those who make their minimum payments. Advocates have successfully pushed for similar reforms in Baltimore.

  • Bitcoin Miner Is Scoring 700% Profits Selling Energy to Grid

    A cryptocurrency mining company in Texas called Layer1 can power down its data-processing centers and sell its unused electricity back to the power grid. Instead of passively consuming energy, they are able to utilize batteries, smart meters, and artificial intelligence software to use more renewable energy and, at the same time, make a profit. While scaling this response can be difficult due to restrictions from utility companies on how consumers get their energy, Layer1 estimates it will save up to $6.7 million annually by cutting production for 30 minutes during some of the hottest days in the summer.

  • Can we harness the Arctic's methane for energy?

    Alternative energy systems in Africa could help inform how to trap methane in the Arctic. Due to permafrost thawing and glaciers melting, methane, a greenhouse gas that contributes to climate change, is leaking into the atmosphere. In Rwanda, a lake-based methane power plant extracts methane from the water and turns it into electricity. But questions remain about how similar systems and infrastructure could work in the Arctic landscape.

  • With the Hippo Roller, a revolution in fetching water rolls on

    After realizing the difficulty that people in South Africa were facing when carrying water back to their communities, two South African engineers devised a machine "that brings all the water back in one trip by rolling it." Users report that while it does not perform well on steep terrain, it can carry much larger amounts of water "effortlessly and in a single trip." So far, 60,000 of these large plastic drums have been sold, but the cost of the machine is often a barrier for those who live below the poverty line.

  • On the Delaware, A Promising New Era in Cleanup of an Urban River

    Once known for being dirty, the Delaware River is being cleaned up by nonprofits and government entities to the point where they’re encouraging people to swim in it again. The Camden County Municipal Utilities Authority diverted the flow of sewage at 52 municipal plants to a new treatment plant, which has kept 15 million gallons of sewage out of the river each day. While overflows have not been completely eliminated, a national advocacy group even named the Delaware its River of the Year because of its improvements in water quality.

  • How Montana Is Cleaning Up Abandoned Oil Wells

    Abandoned oil wells in Montana leak thousands of metric tons of greenhouse gas emissions every year, so the Well Done Foundation is working to plug up those wells. In about a year, the foundation plugged its first three wells and expanded their program to other states. The data on the state of abandoned wells and its emissions isn’t complete, which makes it difficult to know the full extent of the problem. But, “what’s exciting about this is that we can make an impact one well at a time,” says Curtis Shuck, founder of the foundation.

  • How Reedsburg Got Broadband

    Along with electricity, water, and phone, the Reedsburg Utility Commission provides internet access in rural Wisconsin. The fiber network was built almost two decades ago and provides affordable internet access at high speeds. The project started for internal needs and grew to accommodate the school and then eventually the whole region. Current municipal legislation inhibits the type of private-public partnerships that allowed Reedsburg Utility to once build what is now considered an essential service.

  • The ‘solar canals' making smart use of India's space

    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.

  • Waiting for water: On the Navajo Nation, long lines, scarce resources, a cry for solutions

    As the coronavirus spreads throughout the Navajo Nation, many people don’t have access to water to even wash their hands. For generations, the Navajo people have suffered with this lack of water infrastructure, but some solutions have been implemented. For example, the Johns Hopkins Center for American Indian Health has built about 100 hand-washing stations and delivered them to homes in need. Many people are hopeful they will receive more funding to build a more robust water system, but the scale of the problem and the cost of building it are big challenges to overcome.

  • Tackling a notorious waste problem in Africa's largest informal community

    Kibra Green, a grassroots organization in Kenya, mobilizes the young people in the community to clean up their neighborhood. At times, the group has as many as 500 participants for a community-wide clean up. Yet, a lack of steady funding and socioeconomic barriers for volunteers to regularly contribute to the group has made it difficult to scale the organization.
