How much carbon dioxide does a nuclear power plant produce per kilowatt hour?

A nuclear power plant produces less than 60 grams of carbon dioxide per kilowatt hour.

What is the carbon dioxide output of coal per kilowatt hour?

Coal produces 1,000 to 2,000 grams of carbon dioxide per kilowatt hour.

What is the carbon dioxide output of natural gas per kilowatt hour?

Natural gas produces 412 grams of carbon dioxide per kilowatt hour.

Why is nuclear energy considered to have a lower environmental impact compared to coal and natural gas?

Nuclear energy produces significantly lower carbon emissions, which makes it a cleaner alternative compared to coal and natural gas.

What energy source is highlighted as producing less carbon dioxide than both coal and natural gas?

Nuclear power is highlighted as producing far less carbon dioxide than both coal and natural gas.

How much carbon dioxide is produced by solar power compared to nuclear power?

The script does not specify an exact figure for solar power, but it mentions that solar power is a cleaner energy source, with the majority of emissions coming from the manufacturing process, not operation.

What percentage of energy generated by solar power is recycled?

The script mentions that 97% of energy generated by solar power is recyclable.

How does the environmental impact of solar energy compare to other industrial purposes?

Solar energy is generally cleaner, with the main environmental concern being the manufacturing process, but it is still significantly cleaner than many other industrial processes.

What is the significance of the term 'full life cycle' in the context of nuclear power?

The term 'full life cycle' refers to the entire process of nuclear power production, from construction and operation to decommissioning and waste management, during which nuclear energy produces relatively low carbon emissions.
