The name tar sands was applied to bituminous sands in the late 19th and early 20th century. [18] People who saw the bituminous sands during this period were familiar with the large amounts of tar residue produced in urban areas as a by-product of the manufacture of coal gas for urban heating and lighting.

The Athabasca oil sands, also known as the Athabasca tar sands, are large deposits of oil sands rich in bitumen, a heavy and viscous form of petroleum, in northeastern Alberta, Canada. These reserves are one of the largest sources of unconventional oil in the world, making Canada a significant player in the global energy market.
Raw bitumen extracted from the oil sands in northern Alberta is shipped in Canada and to the United States through pipelines, railway, and trucks. Environmental concerns about the unintended consequences of the oil sands industry are linked to environmental issues in the rest of Canada. While pipelines are considered to be the most efficient ...
Tar sands have affected over 75% of the habitat in the Alberta taiga forest due to the clearing of the forests and the oil ponds that come from the extraction. These tar sands also create awful toxic oil ponds that affect wildlife and surrounding vegetation. Oil extraction also affects the forest soil, which harms tree and plant growth.
One can produce a tar-like substance from corn stalks by heating them in a microwave oven. This process is known as pyrolysis. Tar is a dark brown or black viscous liquid of hydrocarbons and free carbon, obtained from a wide variety of organic materials through destructive distillation. Tar can be produced from coal, wood, petroleum, or peat. [1]
The Tar Sand Triangle is located in Southeastern Utah and covers an area of 148,000 acres (600 km 2). It is located between the Dirty Devil and Colorado Rivers in Wayne and Garfield Counties. The Tar Sand Triangle is the largest deposit of oil sands in the United States known today.
In 2003, the oil shale development program was initiated in the United States, and in 2005, the commercial leasing program for oil shale and tar sands was introduced. [ 8 ] [ 9 ] As of May 2007, Estonia is actively engaged in exploitation of oil shale on a significant scale and accounts for 70% of the world's processed oil shale. [ 10 ]
In this book, he explores the Earth's supply of potential replacement fuels for oil. Beyond Oil evaluates a range of primary energy sources ("fuels from the earth"), from petroleum to heavy oil, oil shale, tar sands, natural gas, coal, uranium, and hydrogen (which, as he notes, is actually an energy carrier and not a source), and evaluates the advantages and disadvantages of each.
