Burning coal produces the greenhouse gas carbon dioxide is this a false statement about the use of coal?
No, this is true. Coal is a fossil fuel which holds carbon which has been trapped underground for millions of years. When it is burnt the carbon dioxide is released where it adds to the greenhouse gases in the atmosphere.
Some people want to convert old discarded fruits and rinds into ethanol. This can be mixed into gasoline for cars. When you burn it, it produces carbon dioxide, our most infamous greenhouse gas. This produces more greenhouse gas because we are burning the fruit instead of letting it rot and become buried safely in the ground.
The obvious candidate is the burning fossil fuels (coal, oil and natural gas) to make electricity. However the construction of dams for hydroelectric power can lead to the decomposition of hundreds of acres of vegetation under the water which produces methane, a potent greenhouse gas. Even the burning of biofuels such as wood releases carbon dioxide at a rate higher than it is stored by the growing vegetation.
If you mean is burning methane comparatively better than releasing it into the atmosphere, then yes it is. Methane is a greenhouse gas, twenty-one times more powerful than carbon dioxide. If methane is released into the atmosphere it works as a greenhouse gas. If it is burnt, it released carbon dioxide instead. Carbon dioxide is also a greenhouse gas, but it is not as powerful as methane. So burning methane is good for the environment.
The greenhouse effect does not increase the amount of carbon dioxide in the atmosphere. The greenhouse effect happens because of the carbon dioxide (and other greenhouse gases) in the atmosphere. It is the burning of fossil fuels that increases the amount of carbon dioxide in the atmosphere. Burning coal, oil and natural gas releases age-old carbon dioxide that was laid down underground millions of years ago, so letting it free now puts an impossible burden…
