The UAE recorded the largest increase in renewable energy capacity worldwide over the past decade, a new index has revealed, reflecting the government's key focus on enacting initiatives to achieve its net-zero ambitions.

Capacity in the Emirates surged to 2,540 megawatts in 2020 from a modest 13MW in 2011, Australia-based aggregator Compare the Market said in its “Green Fuel Index” report.

“Countries are increasingly relying more on renewable sources, such as wind and solar, for their energy as they attempt to go green,” the report said.

“The UAE — where renewable capacity has grown by almost 20,000 per cent over the last decade — has traditionally relied on its plentiful supplies of oil but has recently made a big effort to shift away from fossil fuels.”

The UAE is expanding efforts to shift to greener technologies under its Net Zero 2050 Strategic Initiative, which calls for Dh600 billion ($163bn) to be invested in clean and renewable energy sources in the next three decades.

The plan was announced in the run-up to the Glasgow Cop26 summit in November. The UAE won the bid to host Cop28 in 2023.

The plan is a follow-up to the Energy Strategy 2050 programme introduced in 2017 — the first unified energy strategy in the country to be based on supply and demand — which aims to increase the contribution of clean energy in the total energy mix from 25 per cent to 50 per cent by 2050.

It also seeks to reduce the carbon footprint of power generation by 70 per cent, thus saving Dh700bn by 2050, as well as increase consumption efficiency of individuals and corporates by 40 per cent.

The strategy is aiming for an energy mix of 44 per cent clean energy, 38 per cent gas, 12 per cent clean coal and 6 per cent nuclear to meet the UAE’s economic requirements and environmental goals.

Aside from harnessing solar energy, the UAE made history with the opening of the Barakah Nuclear Energy Plant in April 2021, becoming the Arab world's first country to run a nuclear programme.

In its first year, Barakah's Unit 1 prevented the release of more than five million tonnes of carbon emissions, equivalent to more than one million cars driven for a year. Saudi Arabia has also invested heavily in boosting its renewable energy capacity and was ranked second after the UAE in the Compare the Market study. The kingdom's renewable energy capacity surged to 413MW from 3MW over the past decade, it found.

Barbados, Malta and Bahrain ranked in the top five countries that reported the largest increases in renewable energy capacity and are the only ones that recorded a capacity growth of at least 10-fold since 2011.

Norway, Sweden, Canada and Austria rounded out the top five in the list dominated by European countries, with EU member states sourcing an average of 22 per cent of their energy from renewables — two percentage points ahead of the goal they set in 2009 — according to the World Economic Forum.
