Critics of renewables often point to land use as a reason not to do wind & solar. Land use IS a real issue for all energy assets incl renewables unless onsite.

But what critics conveniently forget is huge land impact of fossil fuels. Aerial view of fracking sites in Texas. 👇

🌍 What if the weather conditions are one of the biggest make-or-break factors for Direct Air Capture success?

Our new paper shows that weather variability isn’t just a detail—it can drastically change the cost and performance of DAC.

An invisible renewable energy system - is that possible?

Local opposition to wind and solar farms is often driven by their visual impact—but what if we could plan an energy system that people can't see?

We explored this in our latest study: doi.org/10.1038/s414...
