Though solar produces barely a third as much energy as wind power, it grew more rapidly. The European Photovoltaic Industry Association has tentatively reported that global solar energy capacity passed 100 GW for the first time after seeing 30 GW added in 2012. Much of that is concentrated in Europe, particularly Germany and France, but the EPIA said countries like China were also becoming more significant markets: growth actually slowed in Europe and increased in the rest of the world. Overall, there was barely 40 GW of solar power worldwide at the end of 2010, meaning it's more than doubled in two years.
