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.
