From Science Daily:
A team of Carnegie Mellon University researchers report that the choices U.S. officials make today could limit how the nation's future energy needs are met and could cost consumers billions in idle power plants and associated infrastructure systems.
In the upcoming Sept. 1 edition of the journal Environmental Science and Technology, Carnegie Mellon researchers Paulina Jaramillo, W. Michael Griffin and H. Scott Matthews show that liquefied natural gas (LNG) imported from foreign countries and used for electricity generation could have 35 percent higher lifecycle greenhouse gas emissions than coal used in advanced power plant technologies.
"Investing in LNG infrastructure today could make sense if it helps moderate natural gas prices and keeps existing natural gas power plants running. But making this investment ultimately locks us into certain technologies that make it harder for us to change paths in an increasingly carbon-constrained world," said Matthews, an associate professor in Carnegie Mellon's Civil and Environmental Engineering Department....MORE
