What are the main types of renewable energy?

The main categories are solar (utility-scale and distributed), wind (onshore and offshore), and bioenergy — biogas and biofuel produced from organic waste and biomass. Emerging categories like Sustainable Aviation Fuel (SAF) are extending renewable feedstocks into sectors, such as aviation, that are otherwise difficult to decarbonise.

What is Sustainable Aviation Fuel (SAF)?

Sustainable Aviation Fuel (SAF) is a low-carbon jet fuel produced from renewable feedstocks, including agricultural residues, used cooking oil, and other waste streams. SAF is one of the fastest-growing segments of the energy transition as the aviation industry seeks to cut emissions.

Which companies are leading the renewable energy transition?

The sector includes solar and wind developers, bioenergy and biogas producers, SAF feedstock and fuel companies, and the investors financing clean energy infrastructure. iGrow News tracks funding rounds, partnerships, and market activity across these categories through our ongoing coverage and company database.

Renewable Energy News: Solar, Wind, Biofuel & SAF Investment

Q: What is renewable energy?

Renewable energy is power generated from naturally replenishing sources — including solar, wind, and bioenergy — that produce little to no greenhouse gas emissions compared to fossil fuels. It spans utility-scale generation, distributed and on-site systems, and the biofuels increasingly used to decarbonise transport and industry.

Explainer

What is Renewable Energy?

Renewable energy covers the technologies that generate power from naturally replenishing sources — solar, wind, and bioenergy — reducing reliance on fossil fuels and cutting emissions across industry, infrastructure, and land use. From utility-scale and distributed solar to onshore and offshore wind, and from biogas and biofuel to the Sustainable Aviation Fuel market, the sector spans generation, storage, and the fuels reshaping how the world powers itself.
