Energy Consumption Spectrum And Its Impact On The Global Warming Issue

Most of the energy that we use comes from fossil fuels like petroleum and coal that provide electricity and gas to power our growing energy needs. These fossil fuels, currently providing most of our home energy needs are finite resources, which mean that, they will eventually run out. Furthermore, the world’s population is growing rapidly. Countries are becoming more industrialised and are using notable amount of energy. Individuals are consuming nearly twice as much as energy as they were using 30 years ago. In Australia itself, the total amount of energy consumed by households has increased over the past two decades and is forecast to increase. This could be due to the dependence of our standard of living on easily available energy. Between

As the global population increases exponentially, having passed six billion in 1999, the world population is expected to be 8.9 billion by the year 2050. The worlds energy consumption will increase by an estimated 54 percent by 2025. Energy demand in the industrialized world is projected to grow 1.2 percent per year. Energy is a critical component of sustained economic growth and improved standards of living. One of the major requirements for sustaining human progress is an adequate source of energy. As the world’s technological enhancements and standards of living improve, so too does their appetite for electricity.

On the same note, the energy revolution spoken of above brings forth another advance in the ongoing global climate situation. The nature of the Kyoto Protocol calls for nations to increase research and eventually semi-convert their energy usage to accommodate for cleaner energy. Products such as solar power, wind power, biomass, geothermal power, and hydropower are now widely being studying to create processes that use less coal, oil, and natural gas in production. Altogether the results have

The International Energy Agency’s (IEA’s) preliminary estimate of energy-related CO2 emissions in 2015 reveals that emissions stayed flat compared with the year before, whereas the global economy grew (3). The IEA noted that “There have been only four periods in the past 40 years in which CO2 emission levels were flat or fell compared with the previous year, with three of those—the early 1980s, 1992, and 2009—being associated with global economic weakness. By contrast, the recent halt in emissions growth comes in a period of economic growth.”

Recently, a report by REN21 (Renewable Energy Policy Network for the 21st Century) reported two facts that set the stage for the growth of green energy. First, in 2015, the global economy experienced the largest annual increase of renewable energy; second, developing economies spent more than developed countries on increasing their use of green energy. Another notable fact to mention is that the substantial increase in green energy

Philip K. Werleger Jr., who is a well-known energy economists who also wrote in the International Economy (September 22, 2007) stated that, “History may well repeat from 2001 to 2020 as China, India, and other countries move from developing to developed nations. Consumption can be expected to increase at a pace close to the rate of the economic growth in these nations, just as it did in Europe, Japan, and the United States following the Second World War” And he also stated that, “While these countries may, through efficiency measures be able to produce more GDP growth with less energy, the fact is that they are now involved in building massive amounts of new infrastructure and “that infrastructure is energy intensive.”

Energy is a fundamental factor to the existence of humans on this planet; without it, modern society would be unsustainable. Consequently, the sourcing and production of energy is a critical global issue that must be addressed. Currently, the most common energy sources are fossil fuels: oil, coal, and natural gas. The consumption of fossil fuels is not sustainable in the long run as the resources are not infinite, and as energy consumption increases, the earth’s natural resources (fossil fuels) are depleted. The belief that conventional energy sources are unsustainable prompted the development and use of renewable energy sources such as solar, wind, and hydroelectric. The sustainability of energy is such a demanding issue that Germany

Energy is an integral part of our daily lives. While organisms get energy to move from food, non-living appliances such as phones, lights, cars etc. get their energy from other renewable or non-renewable sources. The majority of energy consumed comes from non-renewable energy sources: fossil fuels (oil, gas and coal) and nuclear energy. In the past few decades, the issue of a potential “energy crisis” has arisen. Since people nowadays use such large amounts of fossil fuels, they will run out in the near future. Out of the three fossil fuels, oil and gas are the most widely used. It is predicted that, without taking into account the new reserves that could become accessible with the advancement of technology, oil and gas

Energy consumption is bound tightly with our daily life especially when we try to maintain our high quality of life (Panwar, Kaushik, & Kothary, 2011). For example, energy consumption is required when people try to light a lightbulb in the night; cars need energy to move. People in the world need to consume an enormous quantity of energy every day to support daily life (see picture 1). Countries’ development is also rely on energy consumption. A research find out that real GDP will be increase by 0.12%-0.39% percent when increase 1% energy consuming. (Narayan, & Smyth, 2008).

As more countries and people become aware of global warming they turn to alternative energy sources

Throughout the history of Earth, the climate has changed to varying degrees by natural causes. When the world first began, the climate was unstable and devoid of the atmosphere that we know of today. It was not until bacteria were able to fix nitrogen did the Earth begin to develop its nitrogen and eventually nitrogen-oxygen atmosphere allowing modern hominids to advance. Earth was cooler after the chaotic activity of its early days subsided, experiencing multiple Ice Ages and periods of severe warming. The last major Ice Age occurred around one-hundred thousand years ago, and profoundly impacted life on Earth. Although Earth continued to go through periodic changes in global temperatures, these changes were eventually relatively minor and life adapted to this climate.

The consumption of energy in developing countries is rising rapidly, and by the end of the next century will dominate energy markets worldwide. Even allowing for a growth rate in the demand for energy in the developing countries 1-2 % lower than the present trend, the demand is likely to exceed 100 million barrels a day oil equivalent (mbdoe) by 2010, and possibly 200 mbdoe (K.Pickering and L.Owen 1995).

Global economy is driven by energy markets. Energy does not only play a significant role in consumer products but also an important input in nearly all the industries. (Efimova O. and

The International Energy Agency estimates that by the year 2003 forty percent of the world's energy production will be from sources other than fossil fuels or nuclear power. Nevertheless, the need for

Energy is one of the major inputs of an economy. It directly affects development of human beings and society. Therefore, safeguarding a cheap and stable supply of energy is one of the main objectives of any country. However, increasing world population, high global energy consumption and depletion of global resources has challenged this objective resulting energy as one of the main concerns today’s world.
