Aboutfitsialnye U.S. data suggest that the USA is absolutely unexpected for many, including supporters of the fight against global warming, sharply reduce emissions of carbon dioxide into the atmosphere. They fell to the level of two decades ago. As it turns out, one of the reasons for this is market-driven.
According to the recently published report of the U.S. Department of Energy, in the first four months of this year, carbon dioxide emissions in the country fell to the 1992 level.
Commenting on the figures, and government and independent experts agree that the decisive factor in this shift was the rapid transition of American energy from coal to natural gas. They note that the active development of shale gas in the Appalachians, and in Texas, Arkansas and Louisiana for the past four years, more than double the wholesale price of a cubic meter to reduce the price of natural gas, displacing dirtier coal. In 2005, the coal-fired plants were given half of the electricity generated in the U.S., now — only one-third.
Comment on this no one foreseen energy-ecological phenomenon correspondent of Radio Liberty asked Myron Ibella, Director of the Energy and global warming Enterprise Institute in Washington.
— Me reduction of carbon emissions in the United States is not very surprising, given the virtual absence of economic growth in the country. At the same time, I agree with many of his colleagues in the fact that the lion's share of emissions reduction can be attributed to the transition of the energy sector from coal to gas. Per unit of power plants using gas, emits half as much carbon dioxide than coal. However, this phenomenon is short-term, because not all closed, but only part of coal-fired plants. I believe that in the long run the economy will recover, it will consume more power — and emissions will go up again. Although someone has high hopes for clean, renewable energy sources, such as sun and wind — their share in power is negligible, these plants have a low efficiency at a high cost. Cost of gas, however, has been steadily declining due to improved technology and the widespread use of hydraulic fracturing. Renewables can not compete with the gas, if only the government will not fund implementation.
— That there is reduction of carbon emissions in the United States for the world, if the third world do not really care about the transition to cleaner energy sources?
— That's right. If emissions in the U.S. are falling, they are sharply increasing in countries such as India and China. In terms of emissions, China is close to total rates of the United States and the European Union combined. One of the reasons is that we have exported a lot of energy-intensive heavy industry facilities in China, which now produces the goods for us. But 80 percent of its electricity from coal, China produces. While China will remain the world's largest industrial manufacturer, the volume of emissions remain the same scale — believes Myron Ibell.
While the latest technology development of shale gas can lower the cost of its production to the United States, some experts point out that it's unclear how they will affect the environment.Source: www.svobodanews.ru
