Solar energy and wind power can be more reliable with the help of storage technology like batteries. This allows renewable energy to be used even when the sun isn't shining or the wind isn't blowing. By using a system called Vehicle to Grid (V2G), electric vehicles can store energy and then give it back to the power grid when needed. This helps make renewable energy more accessible and reliable for everyone. In the future, decentralized V2G battery storage will play a big role in renewable energy systems.
