In today’s rapidly developing world, vast amounts of energy resources are being utilized at an alarming rate, one which can certainly result in the extinction of our valuable natural resources. Moreover, majority of the energy resources utilized today are non-renewable natural resources like the petroleum products which account for nearly eighty percent of all the energy resources used. Thus, exploring alternative forms of energy so as to decrease our dependency on non-renewable forms of energy and consequently save the environment, has become more important than ever before. Today, energy resources used especially, the petroleum products, and in some developing countries like Nepal, fuel wood, are major sources of Green House Gases (GHG), which is the prime cause of climate change. The threat of climate change to the whole of mankind is greater today than ever before. Rapid utilization of Earth’s valuable resources has caused an imbalance in its delicate natural processes, thereby accelerating the rate of climate change, which is in fact a natural phenomenon. Thus, although clima...
With the ever‐rising prices of fossil fuels and the realization that our supply is severely limited, the need for an alternative energy source is rising steadily. Clearly the most efficient of the alternative options lies in bio fuels because they are naturally grown and thus have an unlimited supply, have virtually zero emissions, and can be us...
The United States has many directions to choose from in the oncoming future of energy. “Options for the world's energy future may include surprises, thanks to innovative research under way around the world” (LePoire 1). History has shown that surprises can change generations . Since the mid 1900’s, experts have been conducting research on the way our nation has been using energy. The United States have relied on other countries to gain knowledge with their energy sources. China is one huge partner that helps them out a lot. They have experimented with many different alternative energy sources and have given the U.S lots of helpful information for improving our energy demands. Even though we already meet most of our energy requirements, we still look into improving it everyday to improve our way of living. Despite its ability to be supplied with other nations to be supplied with other nations, the U.S. must invest in alternative power sources if it is to meet the energy demands of the 21st century.
Climate change is occurring at unprecedented rates and is mainly caused by the human expansion of the “greenhouse’ effect which can eventually cause potentially damaging effects in the decades ahead. The natural greenhouse effect is paramount to the maintenance of life because it regulates the Earth's surface temperature from becoming too cold that is unsuitable for life. The earth naturally produces greenhouse gases that make up the earth's atmosphere, including carbon dioxide, methane, and nitrous oxide. These naturally produced gases are good for the earth in certain quantities by protecting it from receiving an excess amount of energy from the sun. When the sun shines light rays onto the earth, a number of the rays are absorbed by the planet, while much of the rays are reflected back to the atmosphere. The greenhouse gases within the atmosphere absorb some of this energy, whereas the rest is reflected back into space, as a naturally occurring cycle that is required to keep the Earth's surface warmer. The problem is that humans are producing far too much amount of greenhouse gases as a result of increased human activities that demand the utilization of energy, which has led to emissions and a elevate in greenhouse gases. A rise within these greenhouse gases in the atmosphere means more heat is trapped in the atmosphere, which tilts the odds of a warmer average temperature that has a greater chance to influence climate change. Nevertheless, a small increase in temperature grows the odds of the negative effects of climate change. Particularly, as the conditions on the planet get warmer due to the number of greenhouse gases being produced there is an increase in the occurrence of record-breaking events including heat waves, droughts, elevating sea level, and the increase prevalence of extreme weather. With the perpetuating vicious cycle,
Energy is the basic necessity of daily life. Nowadays, dependence on fossil fuels for energy needs becoming lower in numerous countries due to the potential of renewable energy to supply sustainable energy to the huge populations in many developing countries who are short of clean and continues energy. Generally, renewable energy can be defined as energy that is derived from natural resources which are constantly replenished and theoretically inexhaustible. Fossil fuels on the other hand can be described as energy that cannot be renewed and will eventually diminish. Thus, in many developing countries renewable energy is the alternative energy to replace non-renewable energy or commonly known as fossil fuels. In addition, according to Sorensen (2004), there is a greater demand for renewable energy sources nowadays due to the uncertainty of fuel price rise in living expenses. Commonly, there are many types of renewable energy available in our world such as wind power, biomass energy, solar energy, hydroelectric power and geothermal energy. However, the main three example of renewable energy are hydroelectric power, solar and biomass energy (Refer to Figure 1 in Appendix 1).
Alternative energy sources are renewable, and is most commonly referred to as free energy sources. There are many alternative energy sources such as hydro power, solar power, wind, biomass, and geothermal. Using alternative sources is more expensive in the long run, but it is the much safer option for our environment compared to fossil fuels. Although everything used is completely free, such as water and wind, the equipment used to generate these things are expensive. There are several pros and cons that come with the utilization of alternative energy sources.
Climate change is one of the biggest concerns for all nations across the globe over centuries. Climate shift refers to changes in patterns of weather which can be indicated through global warming, natural disasters and rise in sea level. There is a group of people, climate change skeptics, argue that climate change is not the result of human activity, meaning that it is naturally occurred. According to Slaght, this refers to internal factors which are the interaction between the atmosphere and ocean, and external factor, such as solar energy variations and volcanic eruption (John Slaght, 2009). However, most scientist claims that human also involve in this process. Consequently, this essay aims to discuss the impacts of greenhouse gases on climate, and then the contribution of human to climate change and lastly, some statistics about the effects of global warming.
The emission of green house gasses due to human activity contributes the most in increasing global warming. Today, fossil fuels are used as a source of energy for transportation, electricity, industrial process and to increase human comfort in this era. Over the last decade humans have created mass amount of industries. These industries have been burning fossil fuels such as coal, which release carbon dioxide and carbon monoxide; carbon dioxide absorbs heat that raises the temperature of the earth. More than 80% of carbon dioxide comes from tr...
Fossil fuels are an important part of life. When you turn on the lights, watch TV, or take a shower, the electricity that you are using is being generated by fossil fuels. The three types of fossil fuels are coal, crude oil, and natural gas. They all take millions of years to form, so they are considered to be “non-renewable”- eventually, the fossil fuels will all be used up. One dangerous biological effect of using fossil fuels is ocean acidification. Extracting and transporting fossil fuels can also be very dangerous. Environmentally damaging accidents such as groundwater contamination, land subsidence, and oil spills occur frequently. Global warming is another possible environmental effect. Fossil fuels have a crucial role in modern society, but since they are non-renewable and dangerous, we should reduce our dependence on them and explore alternative energy sources. Wind energy, hydroelectricity, and solar energy are some examples of renewable fuel sources. There are also many things that people can do everyday to save energy (and, in turn, conserve fossil fuels).
Many climate scientists, researchers, and environmentalists are expressing concerns about shifts in the overall climate of the earth. It is believed that a dramatically dangerous warming is taking place in the overall global climate, a problem that is referred to as "global warming”. Global warming is the observed century-scale rise in the average temperature of Earth’s climate system. This temperature rise is due to the damaging effects of deforestation and the burning of fossil fuels. It is our responsibility to preserve our planet and our way of living but in order to do that we need to act now. If we continue to destroy the planet with no regard as to how serious this matter is there could be several negative effects to us as human being and other living thing on Earth. This is why global warming is truly a global issue and needs to be tackled collectively. We must to act now in order to reduce the dangerous levels of carbon dioxide emissions and we must to work together.

As we approach the future we are faced with many global problems. Most of these problems arise because we have caused them ourselves. We need to face these problems and find a solution. Global warming, although most often overlooked in importance, is a crucial problem of the future directly related to human activities. Global warming is caused by gases humans release into the atmosphere called anthropogenic gases and by deforestation. Anthropogenic gases include carbon dioxide, methane, chlorofluorocarbons (CFCs), hydrofl...
Global Warming One of the most substantial problems in the world today is global warming. This gradual warming of the earth is in occurrence at an extremely slow rate but it is happening. Many scientists believe that as human’s work and release greenhouse gases into the earth’s atmosphere, it can become dangerous for the long lasting life of humans and our environment. “Unless we take immediate action, the impacts of global warming will continue to intensify, grow ever more costly and damaging, and increasingly affect the entire planet - including you, your community, and your family” (“Global Warming Impacts”).
In chapter thirteen of our book, Environment by Raven and Berg, it shows us just how important renewable energy sources are. Currently the United States of America thrives on the use of fossil fuels and nuclear power. The main problems with these types of fuel are that they are both limited and can be extremely harmful to our environment. They cause global warming, air pollution, acid rain, and oil spills (Environment), and not only that, but in the grand scheme of things, these sources really aren’t even that cheap of a fuel source. There are many alternatives to these all but outdated fuel sources.
The world that we live into today affords us the expectation that the flip a switch will turn the lights on. As populations increase and developing nations undergo dramatic economic growth, this energy demand will only continue to grow. The International Energy Agency (IEA) believes that “the world’s energy needs could be 50% higher in 2030 than they are today” (ElBaradei). Given this projected growth, it is necessary for world leaders must take action to secure the energy supply. Meaning that world leaders need to start seriously considering an alternative to non-renewable energy sources. “In 2012, the United States generated about 4,054 billion kilowatt-hours of electricity. About 68% of the electricity generated was from fossil fuel (coal, natural gas, and petroleum), with 37% attributed from coal” (U.S. Energy Information Administration). The fossil fuels that are used to supply over half of our country’s energy are in finite supply and are increasing in price to astronomical heights.
In 21st century almost all devices work with electricity. Electricity makes activity of people easier and more comfortable. Moreover, it plays a great role in development of medicine, science, education, transport and other spheres of human’s life. However, electricity production is becoming more and more problematic because the biggest part of energy for electricity is produced by natural resources, which are neither infinite nor renewable. It means that one day mineral reserves can run out, and, as a result, there will be risk of possible energy crisis. This situation stimulates humanity to transfer to renewable power system. Countries around the world are promoting sustainable energy policies, particularly to reduce greenhouse effect that contributes to severe problems such as Global warming and acid rain (Energy Information Administration (EIA) 2010). The problem of alternative energy source search is also popular in Kazakhstan. Kazakhstan is extremely abundant in natural resources, especially in fossil fuels, which are mainly used as energy sources to generate electricity (CIA Factbook 2011). To be more precise, almost 60% of 4.6 billion kilowatt energy that was produced in Kazakhstan in 2008 came from coal, nearly 35 % - from natural gas and oil, 3% of electricity was created by hydro and nuclear electric stations and rest energy was imported from Kyrgyzstan and Uzbekistan (EIA 2010). It seems that the electricity production in Kazakhstan is mainly based on coal and other minerals. Therefore it is important to find an alternative source of energy in Kazakhstan to reduce its reliance on coal and to avoid power crisis and other negative effects of non-renewable energy usage. Since the territory of Kazakhstan is ...
