Temperatures can be hottest during these times, and people who work daytime hours get home and begin using electricity to cool their homes, cook, and run appliances. Storage helps solar contribute to the electricity supply even when the sun isn''t shining. It can also help smooth out variations in how solar energy flows on the grid.
2. It can be expensive. Because most forms of chemical energy come from organic or naturally occurring items, accessing the resource can be quite expensive. We must mine coal before we can burn …
Energy storage allows energy to be saved for use at a later time. Energy can be stored in many forms, including chemical (piles of coal or biomass), potential (pumped hydropower), and electrochemical (battery). Energy storage can be stand-alone or distributed and can participate in different energy markets (see our The Grid: Electricity ...
