The solar industry comprises businesses and technologies that convert sunlight into electricity or heat. It is rapidly growing, with solar power costs dropping significantly in recent years.

The wind industry, or wind power sector, designs, manufactures and maintains wind turbines and related equipment. It harnesses the wind's kinetic energy to generate electricity, covering areas like wind turbines, offshore wind power, horizontal-axis turbines, and small-scale turbines.

The hydropower industry generates electricity by harnessing the kinetic energy of moving water. Using dams or diversion structures, water flow spins turbines to produce power.

The geothermal industry harnesses Earth's subsurface heat to generate power and provide heating and cooling. This renewable energy source is used for electricity generation, district heating, water heating, and industrial processes, utilising hot water reservoirs at varying depths and temperatures.

The biomass and bioenergy industry uses organic materials to produce renewable energy and bioproducts. Biomass generates heat, electricity, and fuels (bioenergy), creates items like plastics and chemicals, and supports carbon capture and storage (BECCS).

The energy transition industry focuses on shifting from fossil fuels to renewable sources like wind, solar, hydropower, and biomass. Central to limiting global warming to 1.5°C, it aims to reduce fossil fuel price volatility, address energy poverty, cut carbon emissions by 45% by 2030, and create green jobs.

Nuclear power is a reliable, low-carbon, and recyclable energy source. When combined with renewables, it can play a key role in combating global warming.

The battery energy storage industry is a sector that uses batteries to store electricity and release it when needed, helping to integrate renewable energy sources into the power grid.
