Renewables now make up 30% of global electricity generation

Renewable energy, sourced from replenishable natural resources like sunlight, wind, and geothermal heat, is pivotal in electricity generation, heating, cooling, and transportation. It offers off-grid solutions for remote areas, produces minimal greenhouse gases, and enhances energy security due to its wide geographical distribution. As global efforts to mitigate climate change intensify, the shift to low-carbon energy, led by renewables, is accelerating. Technologies such as solar PV and wind are becoming cost-competitive with fossil fuels. Increasing the renewable share in energy systems involves electrifying heating and transport sectors, using biofuels, and deploying solar water heating, biomass burners, and geothermal heating. Achieving climate goals requires rapid renewable energy deployment across all sectors, supported by favourable policies and market conditions.

You can find further information below about the technologies, costs and current developments within each of the seven major types of renewables:
