August 1 (SeeNews) - Global renewable energy production increased by 2.6% between 2013 and 2014, and reached a share of 13.8% in total primary energy supply (TPES), the International Energy Agency (IEA) said last week.
Renewable energy has grown at an average annual rate of 2.2% since 1990, compared to 1.9% growth for TPES. While annual growth rates in the period have been especially strong for photovoltaic (PV) and wind power, at 46.2% and 24.3% respectively, hydro and solid biofuels remain the most used form of renewable energy.
Due to use of solid biomass such as wood by households, non-OECD countries account for around three fourths of renewables consumption. This means almost 50% of all energy in Africa is renewable, while the share in Asia, excluding China, is 25.3% and in non-OECD Americas -- 28.8%. In OECD countries, it is only 9.4%.
Renewables are now the second largest source of global electricity production, IEA said. In 2014, renewables accounted for 22.3% of world generation, following coal which had a 40.7% share, and coming in ahead of gas with 21.6%, nuclear with 10.6% and oil with 4.3%.
The bulk of renewable electricity comes from hydro, while the share of solar, wind, geothermal and tide energies in total renewable electricity in 2014 was 18.7%. Since 1990, global renewable electricity generation has increased at an average annual rate of 3.6%, compared to 2.9% growth for total electricity generation.
