Natural gas-fired generation has been a primary technology of choice by utilities across the country over the past several decades, and by every indication it will remain so. Like every energy source, natural gas has its environmental challenges. The natural gas industry has opportunities to address those environmental challenges while facilitating integration of renewable energy on to the grid. With the technological advent of directional drilling and hydraulic fracturing, many credible sources consider the nation’s shale gas reserves to be a 100 year domestic resource. Although uncertainties exist, this large national supply provides a growing confidence that electric utilities can increase their reliance on gas-fired generation to displace the aging fleet of coal-fired generation over the next twenty years, while increasing the integration of naturally variable renewable energy on to the grid.
