Richard Pike discussed key UK energy facts and challenges at a talk in Lerwick on June 3rd, 2008. Around 30% of energy is lost before reaching end-users. 42% of non-transport energy is used for heating buildings, with a third of that lost through windows. Transportation accounts for 74% of UK oil usage and 25% of UK carbon emissions. Meeting the 2010 EU biofuels target would require converting 19% of arable land from food to fuel crops. Chemical science can help provide energy that is secure, affordable and sustainable.
