Just two decades ago, solar panels and wind turbines were not cost-effective for electricity production. However, they are now among the fastest growing power sources around the world. In many cases, solar and wind power can now achieve a lower kilowatt-hour cost than fossil fuels. These renewable sources also reduce the environmental impact of power systems, since they produce no carbon emissions while operating.
In spite of their economic and environmental benefits, solar panels and wind turbines bring an important technical challenge:
- Sunlight and wind cannot be controlled, and the electricity generation of these systems is constantly changing. For this reason, they are referred to as variable renewable energy, or VRE.
- Solar panels and wind turbines can deliver low-cost electricity with zero emissions. However, VRE sources by themselves cannot meet the power demand peaks that occur in Texas during summer.
