About 23% of energy worldwide is produced by renewable sources

renewableAccording to a recent study by the National Renewable Energy Laboratory in the U.S. , renewable energy generates about 23% of all electricity createed in the world ( 4,892 TWh). Definitely a very good news.

The report was published in late 2013 and was realized using 2012 data. That year the world leader in cumulative installed solar PV capacity was Germany. United States was the first country in the world about geothermal and biomass energies. China led in the wind.

The cumulative global installed renewable electricity capacity has grown no less than 97% between 2000 and 2012 (from 748 GW to 1470 GW). The most used renewable energy is hydropower (which increased from 2,500,000 GWh in 2000 to 3,500,000 GWh in 2012), followed by the wind energy (from zero to 500,000 GWh in 2012 ), then biomass and solar thermal (both still below 500,000 GWh in 2012).

According to published data, the countries with the largest installed capacity of renewable energy are, in order: China, United States, Brazil, Canada and Germany. Countries with large solar policies like Germany, Spain and Italy have also become world leaders in solar PV.

If we analyze the data by separating the types of renewable energy, we can also see which countries are ahead in every field: about hydropower the leaders are China, Brazil, USA, Canada and Russia. In solar power the first contry in the chart is Germany, followed by Italy, USA, China and Japan. In solar thermal the main country is Spain (thanks also to favorable weather conditions), followed by United States, Algeria, Egypt and Morocco (tied) and Australia. By analyzing geothermal energy, first places in the chart are those by United States, Philippines, Indonesia, Mexico and Italy. For wind energy we see on the top China, USA, Germany, Spain and India. Finally, in terms of biomass use, first country in the world is the United States, then Brazil, China, Germany and Sweden.
