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.

Aiming to improve road conditions and cut down on plastic waste, a Scottish engineer found a way to blend the two. After testing a series of different recipes, he found the perfect recipe that is now being used across United Kingdom and the Gulf, Canada, Australia and New Zealand.

Farmers in Iowa have been experimenting with native prairie crops – using native plant species as buffers on farmlands – in an effort to bring more pollination, soil health, water quality preservation, and carbon sequestration to their land. The Iowa State University STRIPS program has been supporting farmers in this effort by connecting them with funding and the information they need to undertake such crops.

Localscapes is a program in Utah promoting more water-efficient landscaping. The program includes state-based horticulturists, landscape professionals, and water experts who help interested people make the most sustainable use of their yards and lawns.
