The share of the world’s population with access to electricity rose from 83% in 2010 to 91% in 2020, increasing the number of people with access by 1.3 billion globally. The number without access declined from 1.2 billion people in 2010 to 733 million in 2020. However, the pace of progress in electrification has slowed in recent years which may be explained by the increasing complexity of reaching more remote and poorer unserved populations and the unprecedented impact of the Covid-19 pandemic. Meeting the 2030 target requires increasing the number of new connections to 100 million a year. At current rates of progress, the world will reach only 92% electrification by 2030.

Between 2010 and 2020, every region of the world showed consistent progress in electrification, but with wide disparities. Electricity access in Sub-Saharan Africa rose from 46% in 2018 to 48% in 2020, but the region’s share of the global access deficit rose from 71% in 2018 to 77% in 2020, whereas most other regions, including Central and Southern Asia, saw declines in their share of the access deficits. Sub-Saharan Africa accounted for more than three-quarters of the people (568 million people) who remained without access in 2020. 

Ensuring universal access to affordable, reliable, sustainable, and modern energy implies accelerated deployment of renewable energy sources for electricity, heat, and transport. Although there is no quantitative target for SDG 7.2, custodian agencies agree that the share of renewable energy in total final energy consumption (TFEC) needs to rise significantly, even though renewable energy consumption did continue to grow through the pandemic, overcoming disruptions to economic activity and supply chains. While the share of renewable capacity expansion rose by a record amount in 2021, the positive global and regional trajectories mask the fact that countries where new capacity additions lagged were those most in need of increased access. Moreover, rising commodity, energy and shipping prices, as well as restrictive trade measures, have increased the cost of producing and transporting solar photovoltaic (PV) modules, wind turbines, and biofuels, adding uncertainty for future renewable energy projects. Renewable shares need to reach well over 30% of TFEC by 2030, up from 18% in 2019, to be on track for reaching net zero energy emissions by 2050. Achieving this objective would require strengthening policy support in all sectors and implementing effective tools to further mobilise private capital, especially in least-developed countries, landlocked developing countries, and small island developing countries. 

 International public financial flows to developing countries in support of clean energy decreased for the second year in a row, falling to USD 10.9 billion in 2019, despite the immense needs for sustainable development in most countries and growing urgency of climate change. The amount was down by nearly 24% from the previous year and may be worsened by the pandemic in 2020. Overall, the level of financing remains below what is needed to reach SDG 7, particularly in the most vulnerable and least developed countries.

The decrease was seen in most regions, with the only exception in Oceania, where international public flows rose by 72%. The bulk of decreases were concentrated in East and Southeast Asia, where they fell by 66.2%; Latin America and the Caribbean, where they dropped by 29.8%; and Central and South Asia, where they declined by 24.5%.

Although the private sector finances most renewable energy investments, public finance remains key to attract private capital, including for creating an enabling environment for private investments, developing the needed infrastructure, and addressing perceived and real risks and barriers for investments in the energy transition. International public flows to countries that lack the financial resources to support their energy transitions constitute a large part of the international collaboration that will be needed for a global energy transition that would bring the world closer to achieving all SDGs.
