If you are looking for news on energy and environmental policy, one of the Libraries subscription databases covers just that: Greenwire. It can be found in the Libraries list of databases http://www.library.unlv.edu/search/databases/index.html#G
Greenwire describes itself thusly:
"With an average of more than 20 stories a day, Greenwire covers the complete spectrum, from electricity industry restructuring to Clean Air Act litigation to public lands management."
Thanks to the Libraries' Government Publications specialist Sidney Lowe for alerting me to this valuable resource. (Some of you may remember Sidney from her days in the Architecture Studies Library!)
