Seasonal thermal energy storage (STES), also known as inter-seasonal thermal energy storage, [1] is the storage of heat or cold for periods of up to several months. The thermal energy can be collected whenever it is available and be used whenever needed, such as in the opposing season.
Thermal energy storage (TES) is the storage of thermal energy for later reuse. Employing widely different technologies, it allows surplus 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.

[citation needed] Polyester makes up about 18% of world polymer production and is the fourth-most-produced polymer after polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC). [citation needed] PET consists of repeating (C 10 H 8 O 4) units. PET is commonly recycled, and has the digit 1 (♳) as its resin identification code (RIC).

The best storage environment for textiles is clean, dark, cool, and moderately dry, with a constant temperature and relative humidity. Ideally, there should be no strain on any one particular area of cloth. There are three basic kinds of storage for textiles, and the choice of which to use relies on the type of textile and the space available.
Thinsulate fibers are about 15 micrometres (0.00059 in) in diameter, [8] which is thinner than the polyester fibers normally used in insulation for clothing such as gloves or winter jackets. Advertising material suggests that Thinsulate is more effective due to the increased density of fibers with decreased size of fibers compared with more ...
