NOVELTY - The electricity-generating arrangement comprises an electricity generator (11) and a power arrangement (12) for the same using a variable renewable energy source. The power arrangement comprises of a number of wind turbines (16) coupled together to drive a hydraulic pump (21), which in turn, drives the generator.    USE - Electricity-generating arrangement using a variable renewable energy source.    ADVANTAGE - The arrangement may be made to operate completely automatically, under computer control, and communicate with a central control hub for maintenance scheduling, fault reporting etc. The configuration of the electricity-generating equipment as regards the production capacity of the electrolyzer and the hydrogen store capacity take into account the wind regime at the site and the electricity demand pattern.    DETAILED DESCRIPTION - A control arrangement (27) senses when demand for electricity produced by the generator falls below what the generator is producing, and diverts power to a rectifier (28) which supplies dc current to the electrolyzer (15) which generates hydrogen by electrolysis of water. The hydrogen is stored in a container (31), which may be pressurized. Oxygen will also be produced by the electrolyzer, and may be collected or vented as desired. The auxiliary driver (14) in the form of an IC engine fueled by hydrogen form the container. The control arrangement will sense when demand for electricity exceeds power supplied by the turbines and will automatically cut in the auxiliary driver to provide auxiliary power or, in dead calm conditions, all the power required to supply the demand. The generation may be through wave power, solar energy converter, a fuel using arrangement comprising an auxiliary driver for the generator and a generating arrangement where the auxiliary driver comprises a dual fuel IC engine;    DESCRIPTION OF DRAWING(S) - The drawing shows a diagrammatic representation of a first embodiment of the arrangement.
