Carnegie Mellon University international engineering and environmental policy expert M. Granger Morgan is challenging U.S. federal and state officials to take the lead in eliminating dangerous carbon dioxide emissions that fuel global warming.
In today's Science magazine, Morgan argues that legislators should impose regulations that will prevent power companies from rushing to build large numbers of long-lived conventional coal plants before regulations on carbon dioxide emissions come into effect. Building such plants today, without making provisions for future control of carbon dioxide emissions, could make such future regulations far more expensive than they need to be, according to Morgan, head of Carnegie Mellon's Department of Engineering and Public Policy.
The U.S. electricity industry plans to build 154 new plants in the next 24 years. Fifty of those plants are slated for construction in the next five years, according to data compiled by the Department of Energy's National Energy Technology Laboratory.
"We're talking about technology such as amine scrubbers, integrated gasification combined- cycles or oxyfuel plants that can capture and sequester CO2 in deep geological formations," Morgan said.
Morgan said that most utility experts anticipate that CO2 emission constraints will be imposed within the next 10 years. "So imposing a law that would provide incentives to encourage builders of new coal plants could begin to help us intensify efforts to combat global warming," he said.
In a recent report to the Pew Center For Climate Change, Morgan and Carnegie Mellon colleagues Jay Apt and Lester Lave showed that the nation needs to cut carbon dioxide emissions from electricity generation by more than 80 percent during the next 50 years to slow the impact of global warming.
"This could be done at an overall long-term cost increase in price of electricity of only about 20 percent -- a small price to pay to save arctic seals, polar bears, coral reefs and other valuable ecosystems," Morgan said.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
