Coal Current Events


Diamonds Do Not Form From Coal
April 22, 2014 | Geology.com

How diamonds form is one of the most common geological misconceptions. Diamonds form under a variety of conditions that rarely, if ever, involve coal as a source of carbon. In fact, most diamonds formed long before the first coal swamp or land plant!

Mineral Rights
April 17, 2014 | Geology.com

In most countries all mineral resources belong to the government. This includes all valuable rocks, minerals, oil or gas found on or within the Earth. In the United States ownership of mineral resources was originally granted to the individuals or organizations that owned the surface. These property owners had both “surface rights” and “mineral rights”. Since then the owners have enjoyed the freedom to sell, lease, gift or bequest these rights individually or entirely to others. Now a single plot of land on the surface can have several different subsurface owners!

Indonesia Oil and Gas Report
April 6, 2014 | Energy Information Administration

“Formerly a net oil exporter and OPEC member, Indonesia struggles to attract sufficient investment to meet growing domestic energy consumption because of inadequate infrastructure and a complex regulatory environment. At the same time, it was the world’s largest exporter of coal by weight in 2012 and the fourth largest exporter of liquefied natural gas in 2013. The government seeks to meet energy demand at home by reorienting domestic energy production away from serving primarily export markets and increasing renewable energy production, particularly geothermal power.” Quoted from the Energy Information Administration publication release.
