    Sammanfattning : How did fossil-fuelled technology find its way to Egypt on its way to global dominance? This thesis presents a socioecological history of energy technologies in agrarian production in pre-colonial Egypt (1820s – 76). It situates them in the nineteenth century, understood as the beginning of the epoch of the Capitalocene; and in Egypt’s case, this is simultaneously part of the rise of Britain’s fossil empire.

    Sammanfattning : Biodrivmedel blev efter millennieskiftet en alltmer prioriterad energikälla för EU och ansågs kunna stävja både klimathot och energissäkerhetsproblem samtidigt som drivmedelsproduktionen skulle gynna sysselsättningen i jordbruket. EUkommissionen formulerade 2007 ett mål om att ersätta 10 % av transportenergin till biodrivmedel. LÄS MER
