Extracting natural gas from underground is easier compared to coal, because of the following reasons:
1. Natural gas is trapped together with oil under a rock layer, when the drilling is finished, the natural gas comes out easily.
2. Natural gas is extracted from subsurface rock formations via drilling.
Also, natural gas is cleaner than coal because of the following reasons:
1. Natural gas emits almost 50% less CO2 than coal.
2. Natural gas can be released with drilling and fracturing. Vertical and horizontal drilling do not have that big effect on the eco-systems.
3. Coal-fired power plants emit not only carbon dioxide: other toxic gases impact people's health condition, these gases can lead to asthma or even to heart attack. Burning coal also comes with No and SO2 emissions, and these are linked to health problems such as asthma, lung cancer, and heart disease.
