The energy stored in a capacitor is given by the formula E = 1/2 × C × V², where E is the energy in Joules (J), C is the capacitance in Farads (F), and V is the voltage in Volts (V). The factor of 1/2 appears because the energy stored is the average of the work done during the charging process. [pdf]
If the current through a conductor with inductance is increasing, a voltage is induced across the conductor with a polarity that opposes the current—in addition to any voltage drop caused by the conductor's resistance. The charges flowing through the circuit lose potential energy. The energy from the external circuit required to overcome this "potential hill" is stored in the increased magnetic field around the conductor. Therefore, an inductor stores energy in its magnetic field. At any given time , is the The energy stored in an inductor is directly proportional to its inductance, meaning that the higher the inductance, the more energy can be stored in the inductor. [pdf]

Electricity can be stored directly for a short time in capacitors, somewhat longer electrochemically in , and much longer chemically (e.g. hydrogen), mechanically (e.g. pumped hydropower) or as heat. The first pumped hydroelectricity was constructed at the end of the 19th century around in Italy, Austria, and Switzerland. The technique rapidly expanded during the 1960s to 1980s ,. When solar production drops (e.g., at night or cloudy days), stored energy is released. Modern systems prioritize load-shifting, supplying power during peak tariff hours. Some even feed surplus back to the grid, earning revenue via feed-in tariffs. [pdf]
