Seasonal thermal energy storage

Seasonal thermal energy storage helps us save energy for when we need it. It works by using hot or cold temperatures to store energy during the summer or winter months, so that it is available for use during the other season. For example, in the summer you can store the energy from the hot air outside in a big container filled with water. Then, when it gets cold in the winter you can use that stored energy to heat your home or office. This is an efficient way of using energy, since energy is saved during the months when it's plentiful, and used during the months when it's rare.
