to 26.3 percent of demand coverage in 2015. Most of the growth occurred in the years leading up to 2012 with little change in baseline capacity between 2012 and 2015. Renewable energy generated electricity had a record year in 2014 when it supplied 42.8% of Spain's national demand. Total annual net generation from renewable sources has grown from around 60 TWh in 2007 to close to 100-110 TWh in the years 2013–2015. Wind power overtook hydroelectric power as the largest source of renewable electricity from around 2008 onwards to produce around 50 TWh from 2013 onwards. Hydroelectric power remains to second largest source typically generating between 25 and 45 TWh per year depending on whether the year is a wet or dry one. Solar PV power grew from just 484 GWh in 2007 to 8,202 GWh by 2012 and has remained at a similar level through to 2015. Solar thermal power grew from almost no presence at 8 GWh in 2007 to 5,085 GWh by 2015. Renewable thermal and other sources have grown from around 2,589 GWh in 2007 to 4,625 GWh in 2015. Total electricity generation from all sources has fallen in Spain from 288 TWh in 2007 to 267 TWh by 2015, a fall of around 7%. Heating and cooling sector Every two years all EU countries as well as Iceland and Norway submit Progress Reports outlining their renewable energy development and movement towards meeting their 2020 renewable energy targets. According to the Spanish progress reports between 2011 and 2014 renewable energy share in the heating and cooling sector grew from 13.6% to 15.8%. In 2014 biomass provided the largest share of RE in the heating and cooling sector at approximately 13.65% of the total, equating to 3.862 million tonnes of oil equivalent. RE from heat pumps provided a little over 1% of the total sector, solar and geothermal power provided a contribution of 0.92% and 0.07% respectively. Transport sector According to the third Spanish submission of EU country Progress Reports covering the years 2013 and 2014 renewable energy use in the transport sector in Spain and Brazil included renewable electricity accounting for energy use of 119.7 k toe. *The bio fuels listed in the report and the table above had not been confirmed as coming from sustainable sources and were awaiting assessment and possible confirmation and as such are not yet able to be confirmed as renewable
