Wind is a clean, renewable energy source, generated by converting the kinetic energy of the wind into electricity using large turbines (onshore or offshore). It is one of the fastest-growing energy sources and offers a sustainable alternative to fossil fuels, being highly efficient in locations with high wind speeds.

Solar energy is a renewable and environmentally friendly source derived from the sun's rays and heat, which is converted into electricity via photovoltaic panels (silicon cells) or heat for heating. It is considered one of the cleanest energy sources, and its cost decreased by 90% between 2010 and 2023.
