Vehicles: fuel economy and energy efficiency?
We have quantified the energy efficiency of 14 different transportation technologies, using real-world data and mechanics equations. Electrification raises auto efficiency 4x, from c15-20% to c60-80%. Novel electric technologies are also unlocking unprecedented fuel economies per passenger mile.

Wind: aim higher?
This data-file contains a simple model for how wind speeds and wind power co-vary with altitude. 2x greater power could likely be harnessed by a kite at 300m than a similar-sized turbine at 80m.

Solar Innovation at Big Oil?
We reviewed 37 distinct solar patents filed across the Oil Majors in 2018. Three ‘leaders’ stood out, each pursuing a different technology strategy.
