WIND FARMS CAN STORE AND DELIVER SURPLUS ENERGY
The worldwide demand for solar and wind power continues to skyrocket. Since 2009, global solar photovoltaic installations have increased about 40 percent a year on average and the installed capacity of wind turbines has doubled. The dramatic growth of the wind and solar industries has led utilities to begin testing large-scale technologies capable of storing surplus clean electricity and delivering it on demand when sunlight and wind are in short supply.
A team of Stanford researchers have looked at the "energetic cost" of manufacturing batteries and other storage technologies for the electrical grid. An issue is whether renewable energy supplies, such as wind power and solar photovoltaics, produce enough energy to fuel both their own growth and the growth of the necessary energy storage industry.
