Saudi Arabia has launched five new renewable energy projects to produce electricity sustainably, as the world's largest oil exporter pursues a goal of achieving net-zero emissions by 2050.

The wind and solar energy system projects, with a combined capacity of 3,300 megawatts, were launched by Saudi Electricity Procurement Company as the main buyer, the state-run Saudi Press Agency reported on Sunday.

Of the five projects, three will utilize wind energy and two will utilize solar energy, Spa reported.

The total output of wind energy projects is 1,800 MW, with one project in Yanbu with a capacity of 700 MW, another in Al Ghat with a capacity of 600 MW and the third in Waad Al Shamal with a capacity of 500 MW.

The news agency said the total capacity of the new solar panel projects is 1,500 MW, with one in Al Henakiyah 1,100 MW and the other in Tubarjal 400 MW.

Under its Vision 2030 economic plan, Saudi Arabia is focusing on renewable energy.

In December, Saudi Arabia announced plans to invest more than $100 billion in renewable energy projects.

It aims to increase the share of natural gas and renewables in its electricity mix to 50% by 2030.

The projects are part of the fourth phase of Saudi Arabia's National Renewable Energy Plan overseen by the Ministry of Energy.

Saudi Arabia is the largest electricity consumer in the region and its electricity demand is growing rapidly.

Total electricity demand in Saudi Arabia is expected to reach 365.4 terawatt-hours (TWh) by 2030, up from 299.2 terawatt-hours in 2018, according to a report by the Riyadh-based King Abdullah Petroleum Research Center.
