The case of fracking in Pennsylvania shows that if experts and fossil fuel industry leaders can cooperate, innovation is possible.

Solar power, wind energy, smart grids, and energy storage often command the current discourse on energy innovation. Yet none of these technologies has transformed the U.S. energy landscape to the degree of high-volume hydraulic fracturing, known as “fracking,” which is unlocking previously inaccessible crude oil and natural gas from underground reservoirs. Thanks to fracking, the 40-year decline in U.S. domestic crude oil production has reversed, and the United States has recently become a net exporter of natural gas for the first time.
For many, this record-setting pace of oil and gas production is no cause for celebration, because it reflects a continued reliance on fossil fuels. Nevertheless, fracking has made oil and gas plentiful and cheap, making these energy resources hard to resist. Like it or not, we may depend on oil and gas—and the technologies that produce them—for the foreseeable future.
Fracking begins after a gas or oil well is drilled and involves injecting a mixture of water, sand, and chemical additives into rock. The high pressure causes the rock to fracture, providing conduits for the oil and gas to flow into the nearby wellbore. Public perceptions of fracking are shaped by controversies between an industry that has downplayed the risks of fracking and the citizens alleging that it has polluted air, contaminated drinking water, and scarred landscapes.
People within communities hosting fracking were scared, looking to experts to make sense of this issue. While experts were easy to find, definitive answers were in short supply. The deployment of fracking had raced ahead of the science needed to illuminate its potential impacts. As fracking activities evolve, uncertainties remain. MORE
