Toxic, biocidal, carcinogenic chemicals injected into Earth's crust
The study finds that shale use suppresses the development of renewables. Under one scenario, for example, the researchers impose a renewable-fuel mandate. They find that, with shale, renewable use never goes beyond the 25 percent minimum standard they set — but when shale is removed from the market, renewables gain more ground.
In light of the recent MIT report stating that fracking slows development of renewable energy technologies, I have decided to post a list of the most common chemicals injected into the ground during hydraulic fracturing (fracking) process, and a second list including the most carcinogenic of these chemicals.
Chemical additives used in fracturing fluids typically make up less than 2% by weight of the total fluid. Over the life of a typical well, this may amount to 100,000 gallons of chemical additives. They are biocides, surfactants, adjusting viscosity, and emulsifiers.
