As the share of distributed renewable power generation increases, high electricity prices and low feed-in tariff rates encourage the generation of electricity for personal use. In the building sector, this has led t.
[pdf] A hybrid energy system integrates two or more electricity generation sources, often combining renewable sources (such as solar and wind) with conventional generators (biodiesel, natural gas, or diesel) and energy storage technologies like batteries and pumped hydro storage.
[pdf] Generally, pumped hydro storage is recognized as one of the most cost-effective methods for large-scale energy storage. Other affordable options include compressed air energy storage (CAES) and emerging technologies like iron-air batteries.
