Method for accumulation and utilization of renewable energy

Abstract

The invention includes a method for both accumulation and use of renewable energy from sun, wind or waves. The invention is based on that the renewable energy, which powers for example a windmill (1), is used for production of liquid under pressure in a liquid pump (3), which liquid is subsequent used for operating a liquid turbine (9), which produces electrical energy, which can be tapped at a place of consumption or connected to an existing electrical distribution net.. When the windmill (1) produces more energy than is being consumed, the excess energy is collected and accumulated in liquid under pressure in a hydrophore tank (17) manufactured from flexible material such as rubber. In periods where the renewable energy source via e.g. a windmill (1) cannot produce sufficient electrical energy to match the consumption, the hydrophore tank (17) supplies liquid to the liquid turbine (9) for its operation.
