When any fossil fuel is burned it produces emissions of carbon dioxide and water vapor. A typical household in a developed country will use approximately 70 kWh per month of electricity for computing and electronics. Each kWh of average coal burned produces 2.23 kg of carbon dioxide emissions while natural gas produces just 0.91 kg per kWh of carbon dioxide.How many more kg of carbon dioxide are produced by the coal plant compared to the natural gas plant from the computing and electronics alone, from a household over the course of one year?

First, let's calculate the total amount of electricity used in a year by a typical household for computing and electronics.

Given that the household uses 70 kWh per month, over the course of a year (12 months), the total electricity used would be:

70 kWh/month * 12 months = 840 kWh/year

Next, let's calculate the total carbon dioxide emissions from a coal plant and a natural gas plant.

For the coal plant, each kWh produces 2.23 kg of carbon dioxide. So, for 840 kWh, the total carbon dioxide produced would be:

840 kWh * 2.23 kg/kWh = 1872 kg of carbon dioxide

For the natural gas plant, each kWh produces 0.91 kg of carbon dioxide. So, for 840 kWh, the total carbon dioxide produced would be:

840 kWh * 0.91 kg/kWh = 764.4 kg of carbon dioxide

Finally, to find out how many more kg of carbon dioxide are produced by the coal plant compared to the natural gas plant, we subtract the carbon dioxide produced by the natural gas plant from that produced by the coal plant:

1872 kg - 764.4 kg = 1107.6 kg

So, the coal plant produces 1107.6 kg more carbon dioxide than the natural gas plant from the computing and electronics alone, from a household over the course of one year.
