Transportation

Japan's bullet train had a sonic boom problem. The solution came from an unlikely source: a birdwatcher who noticed how kingfishers dive into water without a splash.

Transport: The Hard-to-Decarbonize Sector # Transport accounts for about one-third of final energy consumption in most industrialized economies, and it remains overwhelmingly dependent on petroleum fuels. In Austria, the transport sector consumed 361 PJ in 2020—virtually all from oil-derived fuels. Decarbonizing transport is therefore essential to any serious climate strategy. But which technology pathway makes the most sense from a physics standpoint?

Compare the climate impact of electric vehicles versus improved public transit, arguing that better buses and urban planning offer superior decarbonization benefits.
