Answer:
Natural gasses are gasses formed deep beneath the Earth's surface that are used to fuel things. They are considered Fossil Fuel(s).
They are formed when natural material such as decomposing plant and animal matter are exposed to intense heat and pressure underground for over millions of years
Natural gasses are not found in equal amounts all around the globe because each environment has different heat temperatures, ground height, some might not have as much plant life or animal life there for a place like a marsh/swamp will probably have more considering it's mostly warm in these areas and there's a lot of life
In 2019 the US used 31 trillion cubic feet of natural gasses, in 2016 the US consumed 731,071,000 Tons of coal, and in 2017 the US used 7.28 billion barrels of petroleum products
CO2 is in Natural gas so when it burns it's releasing what it's made up of along with the CO2.
Natural Gasses produce 117lbs. per MBtu(Million British thermal unit), Coal produces 200lbs. per MBtu, and Oil produces 160lbs. per MBtu
Solar, Wind, and Hydroelectric are all Renewable and considered Carbon-free. Nuclear power is also considered carbon-free because it does not burn like coal. Wind and Solar can be available everywhere, hydroelectric would only be near water and solar might not be very efficient in places that don't get a lot of sunlight
I would not consider it clean per se but I would say it's one of the cleaner options. It still produces a considerable amount of CO2 into the atmosphere and the process for getting a hold of it probably also has some downfalls to the environment.
How'd we find natural gasses and why did we decide to use them this way?
