Measurement What Counts How are we doing in this climate-fight thing? We have plenty of ways to measure.
Electric motors Two articles on the same topic: electric motors. One quick and easy, one deep and detailed.
Hope Gyrotron Well Drilling for Deep Geothermal Energy Bit-less deep-well drilling teases the prospect of terawatts of clean energy.
Electricity No One Said It Would Be Easy An Australian mining company's first attempt to build an entirely gravity-powered ore train doesn't quite work (yet), but we shouldn't be discouraged.
Materials Copper: The Shorter Story The Earth has a lot of copper, which is good because we're going to need it. But we also need to get better at extracting it in environmentally safer ways.
Hope Sail-Powered Cargo Ships Scale Up A new, much-bigger addition to the world's fleet of hybrid sail/diesel-powered commercial cargo ships.
Energy Geothermal vs Ground-Source Energy: What’s the Difference? Lots of naturally-occurring (low-carbon) heat is underground. Using it to generate electricity and provide heat for our buildings and processes is becoming more common.
Extinction The Long Way Home When a beloved species moves back from near-extinction, we feel joy. But this is the Anthropocene, when many more species are threatened than are saved every year. Part 1 in a series on extinction.
Carbon Ecosystem Engineering: How Animals Positively Shape Their Environments Animal ecosystem engineers modulate the availability of resources to themselves and other species by improving ecosystem structure and function, in the process consistently sequestering and storing more carbon.
Hope EVs Deliver Lowest Lifecycle Carbon Footprint Everywhere Cradle-to-grave GHG emissions of light duty electric vehicles are lower than all forms of their internal combustion-engined equivalents, no matter the region
Materials Cooler Cement Changing the surface microstructure of cement reduces concrete's contribution to global warming by keeping structures cooler
Hope One New Way of Making Low-carbon Cement Even cement production can be electrified, for a 90% reduction in GHGs
Hope Climate for the win! The Vermont Greens FC won their 2025 national championship. Why it matters for climate change.
