An uninterruptible power supply (UPS) or uninterruptible power source is an electrical apparatus that provides emergency power to a when the input power source or fails. A UPS differs from an auxiliary or or in that it will provide near-instantaneous protection from input power interruptions, by supplying energy stored in batteri.

Thermal energy storage (TES) is the storage of for later reuse. Employing widely different technologies, it allows thermal energy to be stored for hours, days, or months. Scale both of storage and use vary from small to large – from individual processes to district, town, or region. Usage examples are the balancing of energy demand between daytime and nighttime, storing summer.

A Trombe wall is a massive equator-facing wall that is painted a dark color in order to absorb thermal energy from incident sunlight and covered with a glass on the outside with an insulating air-gap between the wall and the glaze. A Trombe wall is a design strategy that adopts the concept of indirect-gain, where sunlight first strikes a solar energy collection surface in contact with a thermal mass of air. The sunlight absorbed by the mass is converted t.
