Proposed is a wind turbine having a vertical axis rotor mounted in a fixed cylindrical housing provided with outwardly opening shutters. The rotor consists of a rotating core comprising core blades fastened between two circular bases and forming a Ugrinsky rotor, and an annular impeller configured for independent rotation about said core.

Also proposed are wind power stations based on the wind turbines described above, said turbines being mounted vertically one above the other to form a generating tower, or being mounted on a facade of a high-rise building.

The disclosed technology provides a system and methods for transforming kinetic energy from wind and solar energy from sunlight into three phase electrical energy for local use and available to supply to electrical grids. The system includes a solar panel system and a wind system, which through a gearbox translates kinetic energy from the wind into hydraulic energy in a hydraulic circuit. One or more generators are coupled with the hydraulic circuit to translate the hydraulic energy into three phase electrical energy. In embodiments, a pump motor runs off of a rechargeable battery to supply hydraulic energy to one of the generators when the wind is insufficient to provide sufficient hydraulic energy to the generator. The rechargeable battery may be recharged by diverting energy from, for example, the solar panel system.

The energy transition involves the electrical power supply being almost completely covered by renewable energy sources such as solar plants or wind turbines. However, due to their naturally fluctuating output, these energy sources require the use of large energy storage systems, the realization of which still represents a major problem today. The present invention provides a solution which aims to secure the entire short-term storage capacity needed for the energy transition in Germany (and even Europe). For this purpose, in particular, the invention proposes the construction of a large-scale pumped-storage power plant in the Hambach open-pit mine, as a result of which the can mine be put to subsequent use in a sustainable way. The invention also relates to the construction and partial commissioning of the plant in parallel with the use that is being phased out, in particular that of lignite mining (by 2038). This is to avoid the loss of a significant number of existing jobs. After construction, it is not uncommon for lifetimes of over 100 or even over 1,000 years to be possible, which means that a particular level of sustainability can be ensured.
