Of these, solar PV installations which has grown almost 20 times in the last decade, holds out the most promise to decarbonise electricity generation and to fuel the necessary large scale renewable electrification of services that still run on fossil fuels like transport, heating as well as ensure energy access to the poor and underserved. [...] By the end of 2020, at least 15 countries had enough capacity in operation to meet at least 5% of their electricity demand with solar PV, and this is forecasted to grow both in terms of number of countries as well as in the percentage of electricity demand met from solar PV. [...] TES capacity, installed mainly alongside CSP, represents a significant proportion of global non-pumped hydropower energy storage capacity and is almost double that of utility-scale batteries.7 Solar Thermal Heat The growth in the global solar thermal market declined slightly in 2020, with an estimated 25.2 GWh of capacity added worldwide, down 3.6% from 26.1 GWh in 2019. [...] To be in line with the IEA’s Sustainable Development Scenario (SDS), the share of clean energy technologies such as heat pumps, solar thermal heating, low-carbon district energy systems and biomass boilers, as well as hydrogen boilers and fuel cells, needs to exceed 80% of new heating equipment sales by 2030.12 Another use of solar heat from PVT technology (solar panels coupling PV and thermal hea. [...] Conclusion Solar energy is one of the most important sources of clean and renewable energy in humankind’s efforts to a 100% transition from fossil fuels in global energy systems.
