This document provides an outline and analysis of various renewable energy sources including solar, wind, geothermal, hydroelectric, and biofuels. It details global trends in renewable energy production from 2003-2013, finding that renewable sources provided 22% of global power in 2013 and capacity grew 5% annually over that period. The largest growth was seen in solar and wind energy. China is a leader in renewable energy capacity and production while Germany pioneered solar energy policies. Hydropower remains the largest renewable source but growth has slowed in recent years.

11. Hydropower
Global hydroelectric output grew by a
below-average 2.9%. Growth in China,
Russia, Spain and India was partly offset by
large declines in Brazil and the Nordic
countries.
• China has tapped large quantities of
rivers for hydropower generation.
• Brazil experienced worst drought in 80
years resulting in decline in production.

12. Biofuels
• Major contributors to growth of Biofuel
production b/w 2009-14includes
Indonesia, France,China,India,Thailand,
Malayasia & Argentina.
• Germany remains largest producer of
biofuels in Europe.
• USA leads with 35% growth (2009-14)

13. Facts & Conclusions
 According to Bloomberg, renewable power generation capacity in 2013 made up 13.7%
of world generation capacity, up from 12.6% in 2012, and accounted for 8.5% of world
generation, up from 7.8% in 2012. Investments in new renewable generation assets made
up more than 40% of worldwide investments in all generation assets in 2013 as in 2012 .
 Nine percent of total final energy consumption is modern renewable energy, and up to
another 9% is traditional biomass (mainly used for heating), of which only part is
sustainable, resulting in a total renewable energy share of 18% in 2010 .
 Renewable energy sources (excluding hydropower)—in power generation as well as
transport—continued to increase in 2013, reaching a record 2.7% of global energy
consumption, up from 0.8% a decade ago. Renewable energy accounted for more than
5% of global electricity production for the first time, and 15% of EU power generation .
 Hydropower makes up the largest share of renewable electricity generation by a wide
margin .
 On 2013, global hydroelectric output grew by a below average 2.9%, and accounted for
6.7% of global energy consumption .

14.  In the OECD area the bulk of hydropower resources has already been developed. Outside the
OECD area the situation is different. OECD generation is assumed to grow by 0.6% per year
between 2010 and 2040, Chinese and other non-OECD generation by averages of 3.1% and 2.4%
per year, respectively.
 Global investments in wind power declined by 6% in 2012 and by another 1% in 2013. Investments
in solar power dropped by almost 10% in 2012 and plummeted by more than 20% in 2013.
 Globally, wind energy (+20.7%) once again accounted for more than half of renewable power
generation growth and solar power generation grew even more rapidly (+33%), but from a
smaller base .
 Global biofuels production grew by a below-average 6.1%
 In 2013, approximately 6.5 million people were employed in the renewable energy industry
(excluding hydropower except for small hydropower) worldwide.
 In 2013, the solar photovoltaic sector accounted for 2.3 million jobs. Liquid biofuels, modern
biomass and biogas were large employers (1.4 million, 0.8 million and 0.3 million). Wind
employment remained relatively stable at 0.8 million jobs.
 China remains the largest employer in renewable energy sector in 2013
