A wave energy capture system deployed in water converts mechanical motion induced by waves in the water to electrical energy. A controller of the wave energy capture system receives input regarding real-time wave conditions in a vicinity of the wave energy capture system. The controller applies a control model to the received input to select a value of a control parameter for the wave energy capture system, where the control model includes a model that has been trained using machine learning to take wave condition data as input and to output control parameter values selected based on the wave condition data in order to increase an amount of energy captured by the wave energy capture system. The controller implements the selected value of the control parameter on the wave energy capture system.

A wind turbine system able to withstand up to 150 mph winds, comprising the electricity generating components moved from the nacelle to the top of the tower, positioned vertically, and comprising: a main-shaft bearing; a gearbox; a brake assembly; a high-speed shaft; a generator; and an electrical control cabinet. The purpose of positioning in the tower is to protect the components from high winds, tornados, etc. and to regulate the rotation of the propellers to make more electricity. The turbine can be easily repaired onsite by removing covers on the upper tower; and with snap in replacement parts. Drone, which are stored in the top horizontal housing, can surveil and protect the turbine and the surrounding area. And, solar panels on the sides and/or cover of the top horizontal housing provide energy to the turbine in low and no wind conditions.
