The Wind Energy Industry is involved with the design, manufacture, construction, and maintenance of wind turbines for the purpose of generating a renewable energy.
The Solar Energy Industry utilizes radiant light and heat from the sun harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture and artificial photosynthesis.
The Marine Energy Industry encompasses both wave power i.e. power from surface waves, and tidal power i.e. obtained from the kinetic energy of large bodies of moving water.
