BARILOCHE, Argentina, June 14 (Xinhua) -- Energy ministers from G20 countries met here on Thursday to discuss transitioning to renewable energy and other alternative green energy.

The gathering in Argentina's southwestern city of Bariloche is part of the fourth ministerial meeting of the G20 group of developed and emerging economies, which Argentina currently chairs.

Ministers of energy and natural resources, as well as experts from international organizations such as OPEC and the OECD, are to discuss ways to promote energy efficiency, industry transparency and technology in the sector, as well as alternative sources of energy.

Argentine Energy and Mining Minister Juan Jose Aranguren, along with Canada's minister of natural resources, James Gordon Carr, were to hold a press conference on the deliberations later in the day.

The G20 envoys were also scheduled to tour INVAP, Argentina's state-run company specializing in designing and building equipment for nuclear, oil, chemical and aerospace industries.

A press conference is also scheduled after the meeting concludes Friday afternoon, with Aranguren, Thorsten Herdan, Germany's director general of energy policy, and Yoji Muto, Japan's minister of economy, trade and industry.

The Group of 20 accounts for 77 percent of the world's energy consumption and more than 80 percent of the world's renewable energy capacity, as well as 85 percent of global GDP, two-thirds of the world's population and 75 percent of global trade.
