The growth rate was higher than 30% for the second year. The number of GW-scale markets was increasing. The demand in many countries and regions has increased by more than 40% year- on-year, of which, China and Europe maintained top two markets, and the newly-added installation has reached new highs, which was 87.41 GW and 41.4GW, respectively. 400 Global Annual Solar Installation (GW) 350 China ■ EU America ■India ■ Others 300 250 200 170 60% 350 China 87.41GW, YoY+59% 50% 230 40% EU 41.4GW, YoY+47% 30% India 14GW, YoY+40% 150 115 130 102 106 100 53 73 43 50 20% Brazil 10.6GW, YoY+87% 10% Source: NEA, CPIA, SPE, LONGI 0 0% 2014 2015 2016 2017 2018 2019 2020 2021 2022 2023E 15 www.longi.com#16The global energy transition has accelerated and renewables represented by solar PV keeps rapid growth. Coping with the energy and climate crisis, many countries have begun to accelerate the transition to green and low-carbon energy. According to Global Development Report released by Center for China International Development Knowledge (CIDK), 127 countries have proposed or prepared to propose carbon neutrality target, covering 90% of global GDP, 85% of the total population and 88% of carbon emissions. Net Zero by 2050: a Roadmap for the Global Energy Sector by IEA predicted that, in the announced pledges. case for carbon reduction, the global power generation will double in the next three decades. The renewables will increase from 29% in 2020 to nearly 70% in 2050, mainly from solar PV and wind power. The energy transition has provided unprecedented development opportunities for renewables. With the advantages of cleanliness, safety, universality and cost-effectiveness, Solar PV has become. the fastest-growing renewable energy.
