Data centers drain water supplies. Microsoft is investing big to fix this
Data centers are infamously energy-intensive, but what people aren’t always aware of is that they also require huge amounts of water to keep servers cool. And to make matters worse, data centers are often situated in desert-like places where water is already scarce. Part of the reason companies Read More...
Device mimics photosynthesis to convert sunlight and CO2 into clean fuel
Producing clean fuels that have a minimal carbon footprint is an arduous task as current techniques also create by-products in the process, making it difficult and expensive to filter them out. That may no longer be the case soon thanks to a team of scientists from the University of Cambridge who Read More...
Scientists use popular supplement Spirulina to purify water
Touted for its high protein count and other health benefits, Spirulina is typically used as a supplement. But researchers in Sweden have recently found a way to use the blue-green algae to remove contaminants from water and then make biofuels from what’s left after the process. For the Read More...
Could we 3D-print buildings using local soil instead of concrete?
3D-printed architecture has been getting a lot of press from The Optimist Daily lately. Most recently, we shared a story out of Oakland where a startup called Mighty Buildings is using a 3D printer to create not only the walls and floors of a home but also other elements like the roof and ceiling.

Agroforestry isn’t just good for the planet. It’s also good for wallets
In the latter part of 2016, Ethan Steinberg and two of his friends planned a driving tour across the United States to interview farmers. Their goal was to solve a riddle that had been bothering each of them for some time. Why was it, they wondered, that American agriculture basically ignored trees? Read More...
Scientists discover way to convert captured carbon into a useful commodity
Capturing and sequestering carbon dioxide may be an efficient way to reduce greenhouse gas emissions and slow climate change, but there’s something unsatisfying about this process. The gas is simply captured, compressed, and then buried deep underground. Unsatisfied with this method, a team of Read More...
41 US states show emission cuts and GDP growth go hand in hand
Economic prosperity and environmental preservation are often portrayed as mutually exclusive goals. But do we really have to choose between financial health and a healthy planet for future generations? Research from 41 states across the US says no. Research from the World Resources Institute Read More...
