Global primary energy intensity increased from 5.6 megajoules per dollar of gross domestic product (GDP) in 2010 to 4.8 megajoules in 2018, an average annual rate of improvement of 2 per cent. The pandemic is having a mixed impact on renewable energy development across end-use sectors: global electricity demand declined by 2 per cent in 2020 compared to 2019, but the use of renewables for power generation increased by almost 7 per cent year on year.

However, the share of modern renewable sources in total final energy consumption rose by only 2.5 percentage points in a decade, remaining below 11 per cent in 2018. The share of renewable energy in total final energy consumption increased gradually from 16.4 per cent in 2010 to 17.1 per cent in 2018. People reliant on polluting fuels and technologies are exposed to high levels of household air pollution with serious consequences for their cardiovascular and respiratory systems, increasing their vulnerability to diseases including the COVID-19 virus. For the period 2010вЂ“2019, most of the increases in such access occurred in the most populous low- and middle-income countries and territories: Brazil, China, India, Indonesia and Pakistan. In 2019, 66 per cent of the global population had access to clean cooking fuels and technologies. In addition, the COVID-19 pandemic will impede progress on future electrification. Despite the significant effort made, there may still be as many as 660 million people without access worldwide in 2030. The global access deficit decreased from 1.22 billion in 2010 to 759 million in 2019. Global access to electricity increased from 83 per cent in 2010 to 90 per cent in 2019, with an increase in average annual electrification of 0.876 percentage points. Clean and sustainable energy should be at the heart of the COVID-19 response and of efforts to combat climate change.

Despite significant progress over the past decade on improving access to electricity, increasing renewable energy use in the electricity sector and improving energy efficiency, the world is still falling short in providing affordable, reliable, sustainable and modern energy for all.
