No matter what you energy project involves, you need to consider your fuel source. In most applications except standby generation , if you will be generating energy on-site, the first choice is natural gas. With the advent of fracking , natural gas (methane CH4) is abundant, reliable and price stability has returned. If your local utility utilizes a significant amount of coal in its generation mix, an on-site energy project utilizing natural gas can reduce your carbon footprint by lowering the amount of greenhouse gases emitted into the environment as a result of your operations.
While coal is cheaper on a dollars per btu basis than natural gas, its handing requirements, emissions profile and pollution abatement control systems make it infeasible for all but a select group of large scale projects. However this is not to say that one shouldn’t consider other solid fuels or biogas derived fuels as an alternative to natural gas; particularly, if your business produces a large amount of combustible waste product that is otherwise being landfilled or which future regulation may make land disposal difficult or expense or if there are available bio-gas sources in close proximity (e.x., large landfill or anaerobic digester ).

Hydraulic fracturing is the fracturing of various rock layers by a pressurized liquid. Some hydraulic fractures form naturally—certain veins or dikes are examples—and can create conduits along which gas and petroleum from source rocks may migrate to reservoir rocks. Induced hydraulic fracturing or hydrofracturing, commonly known as fracing, fraccing, or fracking, is a technique used to release petroleum, natural gas (including shale gas, tight gas, and coal seam gas), or other substances for extraction. This type of fracturing creates fractures from a wellbore drilled into reservoir rock formations. http://en.wikipedia.org/wiki/Hydraulic_fracturing
Natural gas (a.k.a. as methane CH4) produces less greenhouse gas emissions (mostly carbon dioxide CO2) than coal, because the energy release is associated with breaking carbon – hydrogen (C-H) bonds during burning (i.e., oxidation reaction) and freeing a single carbon atom of every four C-H bounds that are broken while burning coal results in breaking carbon – carbon bounds resulting in feeing a carbon atom for each bond that is broken.
