People can store energy by using batteries that are charged during off-peak hours when electricity rates are low. People can also use rechargeable batteries in cars and trucks, and charge them during peak usage times such as during the morning and evening commute. Where there is an electricity grid in the community, people can pay to plug-in electric car charging stations during peak usage times so they do not have their cars run out of energy while driving around town OR install solar batteries and generate power for themselves that helps subsidize their neighbours use of fossil fuels such as coal and oil
