  2. Environmental impact of nuclear power - Wikipedia

    en.wikipedia.org/wiki/Environmental_impact_of...

    Nuclear power plants in normal operation emit less radioactivity than coal power plants. [69] [70] Unlike coal-fired or oil-fired power generation, nuclear power generation does not directly produce any sulfur dioxide, nitrogen oxides, or mercury (pollution from fossil fuels is blamed for 24,000 early deaths each year in the U.S. alone [71 ...

  3. Environmental impact of electricity generation - Wikipedia

    en.wikipedia.org/wiki/Environmental_impact_of...

    Nuclear power plants do not burn fossil fuels and so do not directly emit carbon dioxide. The carbon dioxide emitted during mining, enrichment, fabrication and transport of fuel is small when compared with the carbon dioxide emitted by fossil fuels of similar energy yield, however, these plants still produce other environmentally damaging ...

  4. Carbon dioxide in Earth's atmosphere - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide_in_Earth's...

    On Earth, carbon dioxide is the most relevant, direct greenhouse gas that is influenced by human activities. Water is responsible for most (about 36–70%) of the total greenhouse effect, and the role of water vapor as a greenhouse gas depends on temperature. Carbon dioxide is often mentioned in the context of its increased influence as a ...

  5. Nuclear power plant - Wikipedia

    en.wikipedia.org/wiki/Nuclear_power_plant

    Older nuclear power plants, like ones using second-generation reactors, produce approximately the same amount of carbon dioxide during the whole life cycle of nuclear power plants for an average of about 11g/kWh, as much power generated by wind, which is about 1/3 of solar and 1/45 of natural gas and 1/75 of coal. [64]

  6. Atmospheric carbon cycle - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_carbon_cycle

    Carbon dioxide equilibrates between the atmosphere and the ocean's surface layers. As autotrophs add or subtract carbon dioxide from the water through photosynthesis or respiration, they modify this balance, allowing the water to absorb more carbon dioxide or causing it to emit carbon dioxide into the atmosphere. [2]

    Environmentalists once treated nuclear power as enemy No. 1, but the urgency of climate change has led many to reconsider their opposition.

    Caesium-137 concentration in the air, 19 March 2011. Radioactive materials were dispersed into the atmosphere immediately after the disaster and account for most of all such materials leaked into the environment. 80% of the initial atmospheric release eventually deposited over rivers and the Pacific Ocean, according to a UNSCEAR report in 2020.

    These particles were potentially hazardous, even in low-level radiation areas. [10] The radioactive level in each individual hot particle could rise as high as 10 kBq, which is a fairly high dosage of radiation. [10] These liquid hot particle droplets could be absorbed in two main ways; ingestion through food or water, and inhalation. [10]
