Ukrainian scientists invented a generator that uses organic waste from agriculture to produce cheap energy. This method can replace natural gas while disposing of agricultural waste in a way that doesn’t emit carbon dioxide.

The city of Amsterdam funded a blue-green roofs program to reduce both flooding and the urban heat island effect. The water collection system stores and releases rainwater, the variety of indigenous plants increase biodiversity, and the connected digital network allows them all to be controlled remotely.

Philadelphia’s West Laurel Hill Cemetery has gone green. While the burial business may be notoriously filled with chemicals, this cemetery has introduced 50 different sustainability initiatives, including banning machinery use, only allowing biodegradable caskets – or no caskets at all – and keeping the grounds flourishing with native plants instead of manicured lawns. The efforts also include community engagement to bring residents into the environmental shift as part of a larger, cultural trend toward sustainability.

In a collaborative effort between developers, power companies, and the government, a new apartment complex in Utah will be almost entirely powered by solar energy. The complex, developed by Wasatch Premier Communities, will work with Rocky Mountain Power to determine how to integrate such technology into the region’s electricity grid. This kind of development is gaining ground in Utah, and those in the industry hope to educate others of the benefits of going electric.

In 2008, Vancouver’s mayoral candidate Gregor Robertson said he would transform the city to be the world’s greenest by 2020. One decade later, steps toward decreasing greenhouse gas emissions have been made, but the 2020 prospect seems much farther ahead. While the city has run into obstacles, the Canadian city is moving forward to achieve its next goal: for buildings to produce more energy than they use.

Ireland’s energy efficiency agency, Codema, and Amazon partnered to use waste heat from data centers used for computing needs to heat council buildings and a university campus.

Isles, Inc. provides plants, seeds, and support to over 70 community gardens in Trenton, 20 of which belong to schools. In a city where many residents experience food insecurity, Isles also maps food-assets and food deserts, runs a training garden to teach new growers the basics of at-home gardening, and hosts a free summer camp to get young people interested in agriculture and nature. Since the coronavirus pandemic began, Isles has distributed over 100 pounds of seeds, 1,000 pounds of fertilizer, and thousands of seedlings to its garden network members and shifted many instructional workshops online.

As the United States grapples with the already-occurring effects of climate change, there is a growing call from the energy democracy movement to make sure energy efficiency remains equitable and affordable. Initiatives like Mississippi’s One Voice or the South Bronx’s Mothers on the Move recognize that climate change hits low-income first and most and are working to address the unequal power dynamics through shared, power-powered energy initiatives.

In Salt Lake City, a bipartisan coalition of public and private actors, including members of the business, industrial, religious, political, and civic communities voluntarily came together to pass an ambitious twenty year land use plan. The plan, which conserves water, promotes clean air, and imposes new taxes for new rail lines, was made possible by Envision Utah, a public-private partnership that capitalizes on many Utahns' cultural and religious heritage.

Solar power is an important renewable energy in Germany, but when the sun is out, it can overpower the grid. Likewise, when the sun is not out, the reception of solar power decreases. Germany has piloted battery installations that store solar energy for use when the sunlight is not plentiful and has successfully incentivized citizens to use them to lower costs.
