According to the International Energy Agency, the world is making little progress in producing cleaner energy. Despite the development of cleaner energy sources and more energy efficient technologies, the use of fossil fuels and coal continues to dominate. Renewables accounted for 19% of electricity generation in 2012. Among renewables, solar photovoltaic capacity grew 42% to 29–30 GW last year. In 2011, solar photovoltaic generation rose 47% to 65 TWh and is expected to reach almost 280 TWh by 2017. Electricity generated from solid biomass, biogas, renewable municipal waste and liquid biofuels increased around 11% in 2011 to 310 TWh, with expectations of it reaching 530 TWh by 2017. Biofuels accounted for 2% of the demand for final liquid fuel last year. Biofuel production totaled 110 billion liters in 2012, the same as in 2011, due to higher prices for feedstock. In 2017, biofuel production is estimated to reach 140 billion liters. Capacity for advanced biofuels (conversion technologies in the development or demonstration phase) rose about one-third to 4.5 billion liters, with over 100 plants in operation.
