than coal in the short term because it was a less efficient source of
energy.
Weiss said that, while natural gas
burns cleaner, the NETL study concluded that the end - to - end emissions involved in moving U.S. natural gas to an LNG export facility, then liquefying it, then shipping it across the ocean, then de-liquefying it, and shipping it to users in other countries, would be as
energy and emissions intensive, or more,
than using regionally produced
coal — i.e., because of the LNG export supply chain, it has no advantage over
coal.
The problem, according to many
energy analysts, is that
burning pellets creates more global warming pollution
than coal, not less.

energy gain comes out positive.
