- The average monthly bill for United States households is $110 (909 kWh, kilowatt hours).
- Lighting is around 12% of household use, so the average bill for lighting is $13.20.
- Lighting use residentially might be estimated at 4 hours per day.
- So the lighting bill for one household for one hour is estimated at 11 cents.
- There are 117.5 million households in the US (2011 census).
- So the US residential lighting bill for one hour is $12,925,000 (almost 13 million dollars).
- Fossil fuel (coal, oil and natural gas) electricity in the US makes us 67% of the total.
- That makes a bill of $8,700,000 for carbon-dioxide-emitting electricity.
- That is, 8.5 million kWh.
- 1 kWh of fossil fuel generated electricity emits 730 grams (1.6 pounds (lbs)).
- So switching off residential lighting in the US for one hour will save 6.2 million kilograms, or 6,200 metric tonnes of carbon dioxide.
- This equals 6,800 tons of carbon dioxide.

What is the most important source of carbon entering atmosphere?
The most important source of carbon entering atmosphere is industries. Living things, burning fossil fuels and automobiles are other sources of carbon dioxide.
Why is more carbon dioxide entering the atmosphere?
because we have a greater demand for fossil fuels and when you burn fossil fuels a lot of carbon dioxide is released
How can you prevent co2 from entering the atmosphere?
from outside the atmosphere? there is no problem regarding that because space is a vacuum. BUT CO2 has already entered our atmosphere. As long as there are organisms that thrive through the process of respiration, you can't eliminate carbon dioxide from the atmosphere. Even the earth itself releases carbon dioxide without the help of organisms. --- ANSWER: DEPENDS. ^_^

Why it is called green house effect not carbon dioxide effect as it is due to the carbon dioxide?
It's because what is happening is that sun's heat is entering the Earth's atmosphere but not leaving like it's supposed to, kind of like how a greenhouse works.
Terrestrial planet with a thin carbon dioxide atmosphere?
Mars is the terrestrial planet with a thin carbon dioxide atmosphere. Venus also has an atmosphere of carbon dioxide, but it is very thick.
Where does co2 loading occur?
- carbon dioxide is released in the atmosphere: - part of carbon dioxide in the atmosphere is absorbed by the biosphere - part of carbon dioxide in the atmosphere is absorbed by body of waters
