OMA, la oficina de Rem Koolhaas, afamado arquitecto y conocido por su perfil provocador, ha sorprendido estos días con una futurista visión del escenario energético 2050 para Europa. El Guardian lo recoge y en Arkinet han preparado un post más extenso, detallando algunos de los extremos de la propuesta. La Hoja de Ruta 2050 (Roadmap 2050) propone una red de energía compartida e interconectada a nivel europeo que conseguiría una reducción de hasta un 95% (!) en emisiones de CO2 para el año 2050. Entre otras cosas, destaca la reconfiguración que presentan del mapa de Europa atendiendo a las fuentes energéticas que prevalecerían en este nuevo escenario.
