Physical systems can affect human systems in many ways. Climate is one of the many ways. If a human lives in a very cold environment such as Alaska they can become very cold if they do not wear proper clothing and stay warm. The low temperatures can lower the body temperature and eventually can do so so much that the body will start to shut down due to hypothermia. However in contrary a human system can also affect a physical system. For example, if you had that same person in Alaska trying to survive the cold he might cut down a lot of trees for fire wood and to maybe build a shelter. Doing that could cause animals to loose their homes and also it will produce more heat causing the temperatures to potentially rise in Alaska. That is just a few examples of how human systems and physical systems play a role towards each other.

Organic materials (such as food scraps and yard waste) in landfills can decompose and produce landfill gas ( LFG ) over time. Ab

liubo4ka [24]

Based on the data provided:

LFG is used to produce electricity by using it as fuel in combustion turbines

the Puente Hills Landfill will emit 1.94 * 10¹⁰ cubic feet of LFG per year

9.7 * 10¹⁰ cubic feet of methane is prevented from entering the atmosphere.
the number of households that can have their total electricity needs provided by these landfills is 1,368,925 households.

<h3>What is the process of electricity generation from LFG?</h3>

Landfill gas, LFG can be used to generate electricity.

It contains 50% methane which is used as fuel for energy generation.

The process of generating electricity from LFG is as follows:

It is processed to produce methane.
The methane produced is combined with natural gas
The mixture is used as fuel for combustion turbines which then drives energy generation.

<h3>How much LFG is emitted at the Puente Hills Landfill per year?</h3>

From the data given:

ii) 1 million tons of landfill emits 432,000 cubic feet of LFG per day

123 million tons of landfill waste will emit 123000000 * 432000/1000000 cubic feet of LFG per day

The Puente Hills Landfill will emit 53136000 cubic feet of LFG per day

1 year = 365.25 days

Amount of LFG emitted in 1 year = 53136000 * 365.25 cubic feet of LFG per day

Amount of LFG emitted in 1 year = 1.94 * 10¹⁰ cubic feet of LFG per year

Therefore, the Puente Hills Landfill will emit 1.94 * 10¹⁰ cubic feet of LFG per year

<h3>What is the amount of methane prevented from entering the atmosphere by burning LFG to produce electricity at the Puente Hills Landfill over a 10-year period?</h3>

Volume of LFG produced in Puente Hills Landfill in 10 years is calculated below:

1.94 * 10¹⁰ cubic feet of LFG per year * 10 years = 1.94 * 10¹¹ cubic feet of LFG

Volume of methane in 1.94 * 10¹¹ cubic feet of LFG = 1.94 * 10¹¹ * 50% Volume of methane in 1.94 * 10¹¹ cubic feet of LFG = 9.7 * 10¹⁰ cubic feet of LFG

Therefore, 9.7 * 10¹⁰ cubic feet of methane is prevented from entering the atmosphere.

<h3>How many households can have their total electricity needs provided by these landfills in the United States?</h3>

Average yearly household electricity need = 30 kWh * 365.25 days

Average yearly household electricity need = 10957.5 kWh per year

Number of households = total electricity from LFG / average household electricity use per year

Number of households = 15000000000/10957.5

Number of households = 1,368,925 households

Therefore, the number of households that can have their total electricity needs provided by these landfills is 1,368,925 households.
