We've reported previously on various economic impact studies done showing the benefits of local oil and gas development (for example, see here (Oklahoma); here (West Virginia)). The Philadelphia Inquirer is reporting on an updated study for Pennsylvania: "'Our estimates suggest that in 2020 the Marcellus industry in Pennsylvania could be creating more than $20 billion in value added, generating $2 billion in state and local tax revenues, and supporting more than 250,000 jobs,' said the authors associated with Penn State's department of energy and mineral engineering."
Not bad at all.
