Stripe customers can now donate directly to carbon capture projects
If we want to spare the Earth of runaway climate change, we must not only dramatically cut down on emissions, but also remove greenhouse gasses that already exist within our atmosphere. And while carbon capture technologies could play a big role in this, many of these technologies have yet to be Read More...
This startup produces rocket fuel using captured carbon
The fuel needed to launch a rocket into space creates a whole lot of emissions. In fact, each SpaceX launch is estimated to emit 715 tons of CO2, which is roughly as much as 10 cross-country flights on a 747. As spaceflights become more common, there is a need for a more sustainable source of fuel. Read More...
Oregon closes state’s last coal plant in favor of green energy
On October 15, General Electric closed the last coal plant in Oregon in favor of investments in renewable sources. It took a long time, but energy companies are finally coming around to the idea that renewable energy is not only better for the planet, but can also be more affordable and create more Read More...
Panera Bread introduces label to designate items with low carbon footprint
If you enjoy eating at Panera Bread, you might notice a new label on their menus that is intended to help customers make eco-conscious choices. This week, the national soup and sandwich chain announced the Cool Food Meal label, which is placed beside menus items that have a carbon footprint Read More...
The windows of the future could feature transparent wood instead of glass
Wood may sound like the wrong choice of material to replace the glass in your windows, but a team of researchers just proved the contrary. A group of scientists at the USDA, together with several other institutions, has developed “transparent wood,” a glass-like material made almost entirely Read More...
Norway kickstarts one of the world’s largest carbon storage projects
With the world’s largest fleet of electric vehicles per capita, Norway may appear as a global leader in sustainability, but the country still remains one of the world’s biggest producers of oil and gas. Seeking to ramp up its efforts in the fight against climate change, the Nordic country has Read More...
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.
