Top 5 nations that use renewable energy
Solar, wind, tidal and geothermal energy made up only 1.3 percent of total global energy use in 2011, but that's up 15.5 percent from the previous year. This is increasing due to policy and private investment, as well as commitments to reduce environmental impact and dependence on foreign energy sources. Here are the top five countries which are making use of renewable energy.
5. Brazil, 5 percent of world total
Renowned for its biofuel production, Brazil is also involved with developing technologies such as solar water heating, and for relationships with countries outside its region, such as China. Brazil boosted large investments into the wind sector through government auctions for contracts since introducing them in 2009. Brazil seeks to further renewable development and burnish its green credentials through supporting and attracting foreign investment into solar energy - as well as a pledge to have solar power in all twelve venues for the 2014 World Cup.
