Analyze the impact of contaminants in the environment to human health

Energy Alternatives Fracking, or hydraulic fracturing, is a process used to extract natural gas from once unreachable shale rock layers deep in the earth. To release the natural gas, highly pressurized fracking fluids (water mixed with various chemicals and sand) are injected, via steel pipe, into the ground to create cracks or fractures. This releases gas that flows to the surface to be collected in wells. Environmental concerns associated with fracking include water use, toxic chemicals, health concerns, surface and ground water contamination, soil contamination, air quality, and waste disposal. One of the most important aspects of any energy policy is energy conservation. As consumer demand for oil drops, prices decline; the time the oil can be relied on is extended. To help reduce oil use, government regulations, NHTSA (2014), have required greater fuel efficiency in cars through the creation of the Corporate Average Fuel Economy (CAFE) standards. Congress has also required the phasing out of incandescent light bulbs in favor of the more energy efficient compact fluorescent bulbs. Like many new technologies, the upside of the compact fluorescent’s energy saving capacity is countered by the downside that compact fluorescents require the toxic chemical, mercury, for their production. There are many alternatives to using petroleum and coal for energy, but each comes with a unique set of problems. Most new technologies, like solar and wind power, are very costly to start up. Nuclear energy has its own unique drawbacks.
