Solar PV accounted for more than three-quarters of new renewable capacity additions worldwide, followed by wind (20%). The remaining share was made up by hydropower, bioenergy, geothermal, concentrating solar power and marine energy. This marked the 23rd consecutive year that renewables set new expansion records. These systems rely on physics-based processes such as solar energy explained through photovoltaic conversion and wind energy extraction to. This section is devoted to the challenges for biodiversity and ecosystems posed by the expansion of installations for renewable energy production from solar PV, wind, hydropower and other sources, as well as the EU policies addressing these issues. 9 percent, as in the previous year.
