Hydro to lead global renewable energy growth
A US agency report predicts that hydroelectric power will constitute 55 per cent of the renewable energy added globally till 2035. The 'International Energy Outlook 2011' published by the US Energy Information Administration (EIA) said that renewable energy sources were the fastest-growing sources of electricity generation globally. It predicted that from 2008 to 2035, world renewable energy use for electricity generation will grow an average of 3.1 per cent pa and the renewable share of world electricity generation will increase from 19 per cent in 2008 to 23 per cent in 2030.
The report added that of the 4.6 trillion kw-hours of new renewable generation added over the projection period, 2.5 trillion kw-hours (55 per cent) is attributed to hydroelectric power and 1.3 trillion kw-hours (27 per cent) to wind.
The report noted that the greatest increase in hydroelectric growth was outside the developed countries of the Organisation for Economic Co-operation and Development (OECD). In non-OECD countries, hydropower was expected to be the predominant source of renewable energy growth due to mid to large-scale hydroelectric plants to be completed in China, India, Brazil, and a number of nations in Southeast Asia, including Malaysia and Vietnam. The report predicted that world hydropower generation will increase to 5.6 trillion kWh by 2035 from 3.1 trillion kWh in 2008. Wind generation is expected to increase to 1.4 trillion kWh in 2035 from 210 billion kWh in 2008. Other renewables are expected to increase to 1.1 trillion kWh in 2035 from 331 billion kWh in 2008.
