What is the depth of a footprint?
A footprint's depth is determined by the amount of weight above it. So two people with the same size foot, but different weights, will produce footprints of different depths.
What is footprint in construction?
A footprint, from a construction point of view, is the projected area on the ground or basement, upon witch the construction is to be placed. In other words it is the total consumed horizontal area of the vertical span of the object. An example of this Is the Eiffel Tower. The footprint of the Eiffel Tower is the total square under it, not just the four plates it stands on.
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.
How long will it take for a wind turbine to offset its carbon footprint created during its construction?
It depends on the size, but usually three or four months.
Why use double glazing?
Double glazing helps improve energy efficiency in the home as it is has superior heat insulator properties to a single pane window. Double glazed windows usually carry the beenfit of being fitted with excellent anti-burglar locks which are recognised by insurance companies in the UK. The standard for double glazed windows is Pilkington K Glass which is manufactured in Italy. The benefits of double glazing are simple; double glazing saves you money, reduces your energy bills and reduces your carbon footprint. Save money on energy bills by replacing all the single glazed windows in your home with energy efficient glazing. This could save you around £135 per year on your energy bills. Reduce your carbon footprint by cutting down on the energy used to heat your home because less heat is escaping through your windows. You will generate less carbon dioxide (CO2) which is what leads to global warming. Be more comfortable in your home as energy efficient double glazing reduces heat loss through windows and means fewer draughts and cold spots. More peace and quiet because as well as keeping the heat in, energy efficient double glazed windows can insulate your home against unwanted outside noise. Reduce condensation beccause energy efficient double glazing reduces condensation build-up on the inside of windows. The costs and savings of double glazing will be different for each home and each window, depending on the size, material and installer. But on average fitting double glazing to your home can save around £135 a year on your heating bills, in addition to saving around 720kg of CO2 (carbon dioxide).
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 does secondary footprint mean?
the primary footprint is made from burning fuel , from the transport we use and energy we use
How does conserving energy tie into your ecological footprint?
It ties into your ecological footprint because if you start conserving energy you will have lesser measure on the human demand on the Earth's ecosystems.
What is the effect of carbon footprint on energy efficiency?
Lol wut
What is the impact of the carbon footprint of email on the environment?
The carbon footprint of email contributes to the environmental impact through energy consumption from data centers and servers. This energy usage leads to carbon emissions, contributing to climate change.
What is the average carbon footprint in Africa?
The average carbon footprint in Africa varies significantly by country and region due to differences in population, economic activities, and energy sources. However, the overall average carbon footprint in Africa is lower compared to other continents due to lower levels of industrialization and energy consumption.
What is the carbon footprint of an email?
The carbon footprint of an email is relatively small, but it still contributes to carbon emissions due to the energy used to send, store, and read the email.
What is a global footprint?
when the country or place uses energy or more things that aren't Eco friendly more than other places or country's it is making a bigger global footprint
What can energy suppliers do to reduce our carbon footprint?
Energy suppliers can increase their search and support for alternative forms of energy. They can also encourage their customers to be more conservative in their use of energy.
How an organization can improve it carbon footprint?
This is possible by using sources of energy which do not release carbon dioxide.
What are some effective ways to offset your carbon footprint?
Some effective ways to offset your carbon footprint include reducing energy consumption, using public transportation or carpooling, supporting renewable energy sources, planting trees, and purchasing carbon offsets.
Singapore ecological footprint?
Singapore's ecological footprint is high due to its small land area and high population density. The country imports the majority of its resources, resulting in a significant carbon footprint from transportation and manufacturing. Efforts to improve sustainability include investing in renewable energy and promoting green initiatives.
