Electricity is one of the major sources of energy especially for residential consumers. It plays an important role in the daily lives of individuals all across the world from powering daily use electrical appliances to heating and cooling, depending on the weather conditions. According to the World Energy Outlook 2022 published by the International Energy Agency, electricity accounts for nearly 20% of the world’s final consumption of energy.

According to the World Energy Review 2022 report by Eni, solar and wind share increased by 1 percentage point y-o-y to 10% of total power generation, in 2021. Global installed solar power capacity reached 855 GW, while global wind power capacity reached 823 GW by the end of the year.

The demand for electricity is expected to increase further with the shift toward electric vehicles, and global population, among other factors. Based on the Announced Pledges Scenario presented by the IEA which considers the pledges made by governments and corporations across major nations, the global electricity demand is expected to reach 53,810 TWh by 2030, with global supply reaching 61,268 TWh over the same period. If all the concerned parties fulfill their pledges, renewable energy will account for 80% share of the global supply.
