World Energy Consumption
World energy consumption
World energy consumption in 2010: over 5% growth [6] Energy markets have combined crisis recovery and strong industry dynamism . Energy consumption in the G20 soared by more than 5% in 2010, after the slight decrease of 2009. This strong increase is the result of two converging trends. Onthe one-hand, industrialized countries, which experienced sharp decreases in energy demand in 2009, recovered firmly in 2010, almost coming back to historical trends. Oil, gas, coal, and electricity markets followed the same trend. On the other hand, China and India, which showed no signs of slowing down in 2009, continued their intense demand for all forms of energy.
In 2009, world energy consumption decreased for the first time in 30 years (-1.1%) or 130 Mtoe (Megaton oil equivalent), as a result of the financial and economic crisis (GDP drop by 0.6% in 2009).[7] This evolution is the result of two contrasting trends. Energy consumption growth remained vigorous in several developing countries, specifically in Asia (+4%). Conversely, in OECD, consumption was severely cut by 4.7% in 2009 and was thus almost down to its 2000 levels. In North America, Europe and CIS, consumptions shrank by 4.5%, 5% and 8.5% respectively due to the slowdown in economic activity. China became the world 's largest energy consumer (18% of the total) since its consumption surged by 8% during 2009 (from 4% in 2008). Oil remained the largest energy source (33%) despite the fact that its share has been decreasing over time. Coal posted a growing role in the world 's energy consumption: in 2009, it accounted for 27% of the total.
In 2008, total worldwide energy consumption was 474 exajoules (474×1018

J=132,000 TWh). This is equivalent to an average annual power consumption rate of 15 terawatts (1.504×1013 W)[1] The potential for renewable energy is: solar energy 1600 EJ (444,000 TWh), wind power 600 EJ (167,000 TWh), geothermal energy 500 EJ (139,000 TWh), biomass 250 EJ

    The Overall trend in the amount of energy use shown in Figure 1 is not dramatically changed. The amount has only increased by 20 million tonnes (in equivalent of oil) between 1970 and 2030, not much when the overall use in 2030 is expected to be a staggering 230 million tonnes. This does not indicate insecurity as such because the increase itself is not outside of our capabilities to obtain the energy. We faced an increase double that (between 2010 and 2030) in the decades between 1990 and 2010. Therefore this increase of around 9 million tonnes should not be impossible. The problems however are not with the overall figure but instead the individual energy sources within that figure and how we intend to replace our losses to meet this projection.…

    Fossil fuels are currently the most widely used source of nonrenewable energy in today’s society. These sources of energy are used to generate power for both commercial and personal use in a number of different ways. “In 2005, more than 3/4 of total world energy consumption was through the use of fossil fuels.” (Environmental Literacy Council, 2008) Oil, the leading energy resource depended upon to fuel everyday functions produces 43.4 % of our world’s energy. Natural Gas, the second most relied upon resource produces 15.6 % of the world’s energy followed by coal, which produces 8.3 % of the world’s energy. Unsurprisingly, North America is the number one consumer of nonrenewable energy resources, consuming approximately 25 % of the fossil fuels extracted from the earth.

    There are also other forms of energy sources such as geothermal, wind power and other options. The government has set a target of 10% electric renewable sources from 2010. Lots of planning has been involved and many new turbines need to be built this has caused lots of controversy in areas. I believe that wind power will become one of the key energy producers in the future for the…

    Thomas Edison invented the light bulb in 1879. The first oil well was drilled in Pennsylvania in 1859. Since those two historic discoveries, technology and industry have exponentially grown to a point of absolute necessity today. The requirement of energy and oil throughout the world grows with advancement. As developed countries, like the United States, Japan, China, and Canada, progress and grow in population, more demands for energy and fuel are created. Likewise, as less advanced countries bring themselves into the global economy, they will also have increased energy and oil demands. So then the question begs, where are the resources for these demands coming from and what options will there be for future demands? Given current needs and forecasting the global needs of the future, a brief economic analysis will show what the world is up against.…

    For a decade, the World Energy Outlook (WEO) has highlighted the crucial role that energy access plays in a country’s development. During this time, it has developed its own databases on energy access, and published several substantive analytical reports on different elements of this issue. In order to inform the debate about how to overcome energy poverty, the IEA flagship publication has provided energy-poverty data, quantitative analysis and projections for energy use in developing countries. The WEO evaluates energy poverty in the global energy context to inform OECD…

    The term of "Energy", have rarely been mentioned before. However, during the the 21st century, as the growth of economics, it has become a very hot topic which involving economic, natural science and social science and other fields. This paper is focuse on the relationship between the energy comsumption and the economic growth, especially in China. In the first part of this paper, I would like to introduce the definetion of energy and discuss the energy comsumption status over the world by using some statistical database. Additionally, I would like to use some actual case (based on database of China) to talk about the trends of the energy comsumption and the predicts of these changes. Secondly, I will discuss that how is the energy comsumption support and promote the development of the economics theoretically. In the third part of this paper ,I would like to put forward some assumptions that the advantages and disadvantages which related to the increasing energy consumption. One is that will the incresing energy comsumption promote the economic growth and help economic to achieve the sustainable econnomic development under the economic and environmental constraints? For testing my assumption, I would like to ues some real statistical data of the energy consumption of China to provide a deteiled analysis about this situation by using the Endogenous Growth Model which has been mentioned by Robert Lucas. The other assumption is that is there any adverse impact on the environment which has been caused by the increasing energy comsumption? In this part, I will simply introduce the method to analyse my assumption by using the Kaya Identity Equation which mentioned by the Japanese economist Yoichi Kaya. As a result, by…

    Many things these days are taken for granted and used with great liberty, but none more prevalent than the consumption of petroleum based fossil fuels worldwide. As stated in The International Energy Outlook 2006 (Energy Information Administration, 2006a), "World oil consumption rose by about 1.2 million barrels per day in 2005, after an increase of 2.6 million barrels per day in 2004". Current projections indicate increasing demand for oil by the transportation sector, where there is currently not a viable replacement for petroleum, despite emerging technologies entering the marketplace. Case study projections over the 2003 to 2030 period show one-half of the increase in demand originating from the transportation sector. (Energy Information Administration, 2006b) While there are few competitive options to petroleum for the transportation segment, renewable alternative energy resources do exist to lessen the reliance on fossil fuels in other sectors. Resources such as biomass, geothermal, hydroelectric, wind, and solar all do their respective parts to lessen the world 's reliance on fossil fuels.…

    Energy is a key driver for economic growth, constituting about 20% of the Gross Domestic Product (GDP). In 2010, the total primary energy supply was 3127.7 petajoules. The main energy sources of commercial energy supply were crude oil, which accounted 44.7% and natural gas which accounted 41.6%. These sources remain major ones. However, the share of coal and coke increased from 9.1% in 2005 to 11.2 % in these years and only 2.5% came from the non-fossil source of hydro power in 2010.…
