Nowadays, as a part of the human activities, CO2 is produced in large amounts due to the industrial activities. There are four main sources responsible for the production of carbon dioxide into the atmosphere: combustion of fossil fuels, transportation and industry. The first source of emission of CO2 is burning of petroleum and fossil fuels. During the process of combustion of fossil fuels, Carbon reacts with the oxygen resulting in the production of Carbon Dioxide. For example, in order to generate electricity, fossil fuels are burned.
Carbon sequestration Abstract: Carbon containing in atmosphere is increasing in day by day because anthropogenic activity. It is normal range 0.035% in atmosphere. In future period it will become huge problem for world. For overcoming this problem carbon sequestration is very good phenomena. Development technologies to reduce the rate of atmospheric carbon concentration.
BIOFUEL ADVANCES AND ITS APPLICATION - A REVIEW Abstract 1. INTRODUCTION Our main energy sources for human activity are fossil and mineral fuels, nuclear sources. They are harmful to environment because they cause ozone layer depletion, global warning and ecological devastation. Actual energy production can be considered a harmful both in pollution and environmental impact since the industrial revolution in the 18th century. Around 80% of CO2 emissions in the world are originated by the energy sector.
Carbon dioxide is mainly produced by burning of fossil fuel either by cars or factories. Humans need a way to reduce the concentration of CO2 in the atmospheric. By using carbon dioxide as the gas source in enhanced oil recovery, we can reduce CO2 that being is being released to the atmosphere. However, every method has its own respective negative impacts too. Thus, by using carbon dioxide enhanced oil recovery, oil and gas companies can increase the oil production and reduced the emission of carbon dioxide into atmosphere but it will also lead to increase in investment.
Some of the natural ways CO2 is being emitted into the atmosphere include decomposition, ocean release and respiration. Although the greenhouse effect is a natural process and is essential to sustain life, an increase in human activities and technologies has exponentially
From the start of the industrial revolution to modern times, fossil fuels have been the go-to source of energy. Vehicles, homes, and entire cities rely on the use of fossil fuels to power the various technologies. However, this type of energy that many people depend on (oil, coal, and natural gas) are limited resources that will inevitably run out. But from the use of renewable resources, the energy produced by these technologies can replace part of the energy that comes from fossil fuels. In the past, the burning of fossil fuels was a unique innovation with little concern as to what it may face in the future.
Carbon dioxide (CO2), especially, is produces when fossil fuels are burned such as oil and coal. Although these types of gases have always been present in the world's atmosphere, their concentration is increasing with time as more fossil fuels are burned. The gases later warm the Earth s surface by releasing the energy trapped in them. When the GHGs absorb radiation, the stratosphere becomes warm and then re-emits infrared radiation back to the earth’s
Methane, water vapor, carbon dioxide and nitrous oxide are all greenhouse gasses. Carbon dioxide is, however, the greenhouse gas with the greatest increasing atmospheric volume. This is a direct result of human activities such as deforestation and the burning of fossil fuels. These two factors play huge roles in the functioning in modern society thus they can not simply be boycotted, thus if an effort is taken to reduce carbon dioxide output it will be extremely cost intensive as there have been no effective alternative means of harnessing energy than that of burning fossil fuels, therefore it will require great research and great funding. For this reason the global community needs to isolate factors that influence global warming other than the greenhouse effect of carbon dioxide in order to ensure an effective intervention can take place.
These activities includes burning oil, coal and gas thus releasing CO2 into the atmosphere. There are farming practices and land-use changes that increases the amounts of methane and nitrous oxide that’s being released. Factories produces long-lasting greenhouse gases that does not occur naturally in the environment. Deforestation contributes to the greenhouse effect as the trees that are being removed has a critical role by using the CO2 and release oxygen in the process which can form a balance in the atmosphere. Another factor is population growth, because more people will use fossil fuels for heat, manufacturing and transportation and this will just increase the amount of greenhouse gases in the atmosphere (West,
Over the years, our main energy source has come from fossil fuels such as oil, coal and natural gas, which are non-renewable sources. With the increasing human population, these fossil fuels have been in high demand and this poses a threat in the future in terms of climate change. In the 21st century, the big concern has been about assuring that there will be enough affordable energy in the coming years and in order for human beings to be on a sustainable path, there has to be a further implementation of climate measures and an up rise of renewable sources in the coming future. Fossil fuels are predominantly made up of oil, coal and natural gas and are known to be man’s best friend, accounting for almost 90% of the usage of energy sources for over half a century
