Very few of these deposits have truly been "discovered" in recent years. Oil company geologists knew of most of these shale gas and shale oil deposits decades ago. How many times did simple farmers discover natural gas venting into their wells after they dug them?
Sorry but...so what? Oil has been around for millions of years - we just didn't posess the technology to use it or see it's value.
The problems with shale gas are already well documented, such as leaking into aquifers. Check out the movie "Gasland" for examples of rural residents who have so much gas coming up through their pipes that they can set their tap water on fire!
No thanks. Though the movie is well regarded from an artistic point of view, it's well known that it is also scientifically inaccurate and agenda -driven.
But, be that as it may, natural gas makes a poor choice for a transportation fuel, since it has to be compressed and is highly flammable. It also burns hotter, and expected engine life is cut in half. And how are airplanes going to fly on natural gas?
This is all very interesting but I wasn't discussing natural gas as a transportation fuel. I said "energy source." It is a viable source of energy with many uses. And it's natural - unlike nuclear energy, for instance.
And abundant.
Yes, alot of people are shocked when they see some of the numbers on resource and energy
Maybe some people are shocked, but I'm not. With my husband's career depending on oil and gas, he and I stay as informed as possible.
In fact, he's currently working in the Marcellas shale. If you are truly interested in how oil and gas companies implement policies and practices in order to protect the environment, maybe you could write out your specific questions and I can pass them along to him to address. As an oilfield consultant with over 30 years of experience in fracking, he is a good source of first hand information.
Back in the early 70's, I recall several Popular Science and similar publications running cover stories on shale oil and how it could be extracted. It's exactly the same as the tar sands -- everyone knew it was there, but did not think it was worth more than providing asphalt for paving roads. It's the cost (EROEI) of these deposits, the ecological damage from extraction, and their high carbon footprint that kept them off the oil market until now.
Technology continues to advance, and supply and demand will continue to force us to develop and implement new innovations for energy sources, including but not limited to tar sands, gas shales, etc.
For the record, I agree that our research and development of energy sources should NOT be limited to what we know to be a finite energy source (fossil fuels). That would be incredibly stupid and short sighted.
Tar sands oil extraction and development produces three times the carbon emissions of standard oil, and it even has a higher carbon output in energy costs to move the crud through oil pipelines. So far, less than 3% of the known available tar sands deposits have been extracted, and most people who live in Alberta's Northern Boreal Forest, and along the proposed pipeline routes for dirty oil want to keep it that way! Two or three barrels of fresh water are used for the production of each barrel of what they are calling "oil" and the runoff goes into massive tailing ponds that already dwarf the sludge ponds of so called "clean coal" electric generating stations, like that one that the TVA owned which broke and contaminated a section of the Tennessee Valley that had the misfortune of being downstream. Time and time again, the proponents of these systems live far away from the site. In Tennessee, it was mostly poor, rural farmers who were downstream and had their lands ruined; in Alberta, it is Northern Cree and other Aboriginal nations that are very poor and don't have large sums of money to lobby for their interests, which will have their land destroyed by an expansion of tar sands developments
Be cautious when reading up on this topic - there's lots of hyperbole and exxageration out there from a wide variety of sources.
There are huge advances in ecological protection. For instance, my husband is working with a research and development company that is developing a method to clean and recycle the water used in fracking operations. I can't say more about it at this point, but let's just say it's very exciting and will probably be implemented in 2012. This is a huge step toward continuing to improve safety standards and practices and typical of the ongoing focus on protecting our environment, which is, contrary to some "sources" actually very important to the vast majority of oil and gas companies.
