Chevron has decided to invest in Indonesia's "steam fields".

The company is known for its oil wells, gas fields and gas pumps. Yet what Chevron technicians were happy to find in the Indonesian subsoil has nothing to do with crude oil or methane. In fact, the 84 drillings at a depth of over 3 meters have allowed nothing but steam to be brought to the surface. So much and so hot (315°) that it runs 24 hours a day some of the turbines that supply the capital Jakarta with electricity. The place where the drillings were made is not accidental. Indonesia, 24 islands "sitting" more or less comfortably in the volcanic ring of fire in the Pacific, has 17% of the world's geothermal energy deposits and today with 40 billion dollars, has no rivals in Asia and is second only to the United States as regards investments in this specific sector. All thanks to the investments of the World Bank. And even before the promise, made last February by President Susilo Bambang Yudhoyono, for the government to offer incentives to the renewable energy industry, takes shape.
