Mobile “CityTree” Installations Use Moss to Clean Air in Urban Areas

At the Fujitsu factory in Japan, a significant decline in demand for semiconductor computer chips meant the company had large empty factory space sitting unused. A new business approach allowed them to dually address both the need to evolve their business model with a global decline of viable agricultural space needed to grow the world's food. Now, the factory houses indoor vegetable gardens, soil free and less resource-heavy than traditional farmland.

With the prices of solar technology dropping and the opportunity to save drastically on energy usage and costs, businesses and organizations across the country are investing more in solar infrastructure for their buildings and facilities. The Better Buildings Initiative of the US Department of Energy is helping by providing guidance and documenting effective approaches and financing for renewables installations - from hotels, to schools, to big box retail.

Ohio has more than 50 land banks, which are best known for reducing blight by demolishing old buildings, but several land banks are trying creative ways to enhance their land on a budget. Successful projects include a program for locals to redevelop old lots, a pop-up art gallery in a condemned house, and urban forests to make communities more welcoming. The collective effect of these projects is to revitalize cities all across the state.

The consumption of meat and dairy has long been deemed a leading cause of climate change, yet production continues to rise. To contribute to environmental sustainability, Dale Vince – owner of the U.K.’s Forest Green Rovers soccer team – has achieved the status of having the world's first carbon neutral team. From vegan-only menus to a solar-powered grass-cutter, the organization is bringing light to this topic in front of a new audience.

Funded by federal grant money, the state, and the Office of Naval Research, Hawaii County public transit has developed its first hydrogen-powered shuttle bus. What’s been called the “fuel of the future,” hydrogen fuel cells create a power source that’s only emissions are clean water vapor. While a seemingly viable and scalable clean-energy source, such development and infrastructure requires large financial investments that many states have yet to prioritize.

Solar power is a great advancement for renewable energy, but traditionally relies on connecting to a grid in order to function correctly. So when hurricanes hit Puerto Rico, even those with solar panels lost access to electricity. A micro-grid offers an alternative solution, however, by relying on battery power.

Pennsylvania law is preventing a Philadelphia neighborhood from converting an empty lot into a solar farm, but community members are working to fight against this by citing neighboring states that are seeing positive impact from similar projects. One such project is in Massachusetts where shared solar energy systems is helping to offset "80 percent of the power needs of a nearby assisted living facility, an affordable housing development, a family-owned hardware store and a non-profit serving those with disabilities."

A grass blend formulated specifically for northern Utah’s environment uses at least 30 percent less water than typical turf.

As building developers in Kenya design new structures that are more environmentally friendly and sustainable, they can look to the Garden City Mall in Nairobi as a successful example. This mixed-use development with shopping, residential, and office spaces uses solar energy, which helps cut energy costs by over 30 million shillings each year. The mall also was the first in the region to receive an international green building certification.

A startup is making buildings more eco-friendly by converting their energy needs from oil and gas to electric heat pumps. BlocPower is a Black-owned clean tech startup that provides a no money down lease option, making it financially accessible.
