Is nuclear energy environmentally friendly?
I know there is a lot of controversy about this but I would say not. I would say it was friendlier than coal or oil in terms of carbon footprint, but neither coal nor oil has the potential for widespread destruction that nuclear has, even in a worst case scenario for global warming.Proponents of nuclear power point to lack of pollutants and a carbon footprint that is nearly nothing. But there are issues with these ideas, and they ignore a much bigger picture.First of all, nuclear energy does produce considerable pollution. Uranium mining and refining are destructive to the environments in which they are done. Tailings need to be decontaminated, which is very expensive and uses a lot of oil. In the United States, the enrichment is done in a plant powered by what has been called the dirtiest coal burning plant in the country.Until about 2004, studies on the nuclear carbon footprint almost never were done on the cradle to grave basis that is standard for a total carbon footprint. They did not include construction, decommissioning, or waste disposal. On that basis, the carbon footprint of nuclear power were given at an average of 13 grams CO2 equivalent per kilowatt hour (gCO2e/kWh).By contrast, the carbon footprint of solar photovoltaic cells was always calculated on the cradle to grave basis, and since the cells used a lot of energy to produce, production leaked traces of highly powerful global warming gasses, and the cells had low efficiency, they were calculated to produce about 105 gCO2e/kWh.More recent studies do standard total carbon footprint on nuclear, and both the manufacture and efficiency of solar cells have improved. The result is that the more recent information is that solar cells have a carbon footprint of 35 to 40 gCO2e/kWh, and the nuclear footprint is about 90 gCO2e/kWh. By contrast, wind and hydro have about 15-20 gCO2e/kWh and combined cycle natural gas in a cogeneration system has about 445 gCO2e/kWh.So the carbon footprint of nuclear is about 5 to 6 times that of hydro and wind, about 2.5 times that of solar cells, and about 20% of efficient natural gas.There is another environmental problem with nuclear, and that is high level nuclear waste. No satisfactory way of dealing with the waste has been developed in the history of nuclear power, over half a century. The US government position is that nuclear waste is dangerous for about a million years. Actually, it will take nuclear waste about six million years to have its radioactivity reduced to the level of naturally occurring uranium ore, which is not all that safe. We do not have a way to guarantee the environmental safety of the waste for even a fraction of that time. It is more than a 1000 times the age of the pyramids, more than 5000 times the age of our oldest politically body, and more than 100,000 times the age of our youngest volcano.The good news is that renewable energy systems are being developed at an impressive rate.
Is desalination expensive?
yes but the Carbon footprint will be increased by 180 kgs per 60, 000 of water and that equates to a full tank of gasoline, however, that is less than travelling from Perth to Sydney! -------------------------------------------------------------------------------------------------- On the other foot, the construction cost are very large, the running costs are big and on-going, and there is still resitance from the neighbors on the impact on the local community from construction and also from have a large, noisy, operating 24/7, industrial size building stuck on your local beach betwen the houses bought for the ocean view and the ocean.
What is csa w59 in welding?

Technology has allowed for the construction of skyscrapers and other high rise buildings how could these buildings be viewed as having a positive and negative environmental effect?
Skyscrapers can positively impact the environment by reducing urban sprawl, allowing for more efficient land use and preserving green spaces. They can also incorporate sustainable technologies, such as energy-efficient systems and green roofs, to minimize their ecological footprint. However, their construction and operation can lead to negative effects, including increased energy consumption, urban heat islands, and potential disruption of local ecosystems. Additionally, the materials and resources used in building these structures often contribute to carbon emissions and environmental degradation.
How many years does it take to offset the carbon footprint of a wind turbine?
The time it takes for a wind turbine to offset its carbon footprint varies depending on factors like the turbine's location and size. On average, a wind turbine typically offsets its carbon footprint within 6 months to a year of operation.
Does geothermal power leave a carbo footprint?
A small one yes. To harvest the geothermal energy you need to drill, build plant and infrastructure. This drilling, and construction has a carbon footprint (it needs energy to do). However the geothermal energy harvested has no carbon footprint.
What type of questions would you ask on an interview about carbon footprint?
Can you explain what a carbon footprint is and why it's important? How do you think individuals can reduce their carbon footprint in their daily lives? What strategies would you suggest for a company looking to lower its carbon footprint?
How can we reduce your carbon footprint?
If you want to reduce your carbon footprint, you can reduce your emissions of CO2 (carbon dioxide) into the atmosphere.
Where can one find a carbon footprint calculator?
There are many places to find a carbon footprint calculator. The Environmental Protection Agency offers a carbon footprint calculator on their website.
What is a sentence using carbon footprint?
If Bigfoot were made of coal, he would have a massive carbon footprint.
Do cars produce a carbon footprint?
Yes. Your carbon footprint is the measure of how much carbon dioxide equivalent you, or any of your activities produce. A car burns petrol (gasoline) so its use has a carbon footprint.
What part of a persons carbon footprint?
The amount of carbon dioxide emissions from transport each day is part of a person's carbon footprint.
What is the carbon footprint of the average American?
The carbon footprint of the average American is around 16 tons of carbon dioxide per year.
What is a carbon footprint rap?
A carbon footprint rap is a song or poem that uses rhythm and rhyme to raise awareness about environmental issues, particularly related to carbon emissions and their impact on the planet. It often highlights the importance of reducing our carbon footprint by making sustainable choices in our daily lives.
What is a footprint calculator?
Footprint calculator can be carbon footprint calculator or ecological footprint calculator, which can give data about your impact on environment.
Carbon footprint is measured in units of what gas?
The carbon footprint is measured in the amount of carbon dioxide (CO2) that has been emitted over the full life cycle of a product or service.
