WHERE OUR ENERGY COMES FROM
Fossil fuels have changed the course of human history. Cars, airplanes, and other fossil-fueled inventions changed everyone’s life. Without fossil fuels, life would be very different (NASA, 2019).
But there is a price for success.
Fossil fuel changed history for sure - both good and bad; it also is the main cause of Climate Change.
COAL
-
When coal is burned it releases a number of airborne toxins and pollutants. They include mercury, lead, sulfur dioxide, nitrogen oxides, particulates, and various other heavy metals. Health impacts can range from asthma and breathing difficulties to brain damage, heart problems, cancer, neurological disorders, and premature death.
-
When you burn charcoal in your grill at home, ash is leftover. The same is true for coal-fired power plants, which produce more than 100 million tons of coal ash every year. More than half of that waste ends up in ponds, lakes, landfills, and other sites where, over time, it can contaminate waterways and drinking water supplies.
-
Chemically, coal is mostly carbon, which, when burned, reacts with oxygen in the air to produce carbon dioxide, a heat-trapping gas. When released into the atmosphere, carbon dioxide works like a blanket, warming the earth above normal limits (UCSUSA, 2019).

OIL
-
The construction and land disturbance required for oil drilling can alter land use and harm local ecosystems by causing erosion and fragmenting wildlife habitats and migration patterns. When oil operators clear a site to build a well pad, pipelines, and access roads, the construction process can cause erosion of dirt, minerals, and other harmful pollutants into nearby streams (UCSUSA, 2019).

GAS
-
One way to get natural gas is with something called hydraulic fracturing, or “fracking.” Sadly, there are environmental concerns over fracking. People worry that these chemicals can get into drinking water (NASA, 2019).
-
The drilling and extraction of natural gas from wells and its transportation in pipelines results in the leakage of methane, primary component of natural gas that is 34 times stronger than CO2 at trapping heat over a 100-year period and 86 times stronger over 20 years (UCSUSA, 2019)
