Fracking has changed energy. It involves the usage of explosives, chemicals and millions of gallons of water. These things create fractures in shale deep underground. It has unlocked new supplies of natural gas that was previously too difficult or expensive to tap. In the US, fracking has transformed the industry. Europe and China have twice the U.S.’s shale-gas reserves. Investments in fracking could change the global energy landscape and reduce the world’s dependence on the Middle East and African resources.
