Seasonal thermal energy storage (STES), also known as inter-seasonal thermal energy storage, 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. For example, heat from solar collectors or from air conditioning equipment can be gathered in hot months for space heating use when needed, including during winter months..

While it is possible to repurpose old CDs to create a basic solar panel by using their reflective surface to focus sunlight onto photovoltaic cells, CDs are not optimized for capturing solar energy and are not practical for efficient photovoltaic conversion. They can be used for experimentation or educational purposes, but they won't generate significant electricity like traditional solar panels1234.

Hydraulic power systems use pressurized fluid to transmit power1. The fluid used is usually a water-soluble oil or water-glycol mixture1. Hydraulic systems can operate using many different fluids, including multigrade engine oil, automatic transmission fluid, and more conventional antiwear (AW) hydraulic oil2. The choice of fluid depends on the equipment and how it will be used2.

In 2001, the Australian government introduced a mandatory renewable energy target (MRET) designed to ensure renewable energy achieves a 20% share of electricity supply in Australia by 2020. The MRET was to increase new generation from 9,500 gigawatt-hours to 45,000 gigawatt-hours by 2020. The MRET requires wholesale purchasers of electricity (such as electricity retailers or industrial operations) to purchase renewable energy certificates (RECs), created thr.
