the report shows that in 2010, renewable energy supplied an estimated 16% of global final energy consumption and delivered close to 20% of global electricity production. Renewable capacity now comprises about a quarter of total global power-generating capacity. Including large and small hydropower (an estimated 30 GW added in 2010), renewable energy accounted for approximately 50% of total added power-generating capacity in 2010. In 2010, existing solar water and space heating capacity increased by an estimated 25 gigawatts-thermal (GWth), or about 16%.
