The last decade (2004 – 2014) saw a steady increase in the global demand for renewable energy. While overall primary energy supply from renewables in 2004 was 57.7 EJ per year, by 2013 the total supply had grown to 76 EJ annually — an overall increase of 30%. Development of renewables is described in a report by REN21 (Renewable Energy Policy Network for the 21st Century) "10 years of renewable energy progress".
