In a recent New York Times article, two new studies regarding natural gas have been released; one by Robert Howarth of Cornell University and another by David Hughes of the Post Carbon Institute. Both of these articles state that natural gas will be more harmful to the environment than coal or even oil.
The chief component of natural gas is methane, which is more efficient in trapping greenhouse gases than carbon dioxide. This became a significant issue when studies found that methane is escaping into the atmosphere in far larger quantities, close to 8%, than originally thought due to leaks in loose pipe fittings.
Two weeks ago, President Obama indicated that natural gas will be a significant part of the energy production vision for this country’s future. It has been suggested that the natural gas production is to increase by fourfold by 2035.
I am torn by the information that I have just read. I have always been a natural gas proponent, but the new studies have me doubting what the right course of action is for this country. If we are to increase natural gas production fourfold, that is a tremendous amount of methane emitted into the air. Add that to the environmental impact the increased amount of gas wells we will have at the time, has me questioning this method. The natural gas industry won’t tighten up on their production with reducing the amount of gas that leaks out into the atmosphere or capture the methane due to economic reasons. In addition, there are already many natural gas drill sites and to quadruple them has me in a doubtful state.
I do think natural gas can be a bridge to the renewable future combined with energy efficiency. However, a lot more validation of these studies must be done to verify their outcomes in order to be properly implemented.
