3.2 How and why is the demand for energy changing? Economic Social Technological
Economic For all countries, no matter what their present stage of development, demands for energy are rising. World marketed energy consumption is projected to grow by 57 percent between 2004 and Graph shows the most rapid growth in energy demand for nations outside the Organization for Economic Cooperation and Development (OECD), especially in non-OECD Asia, where strong projected economic growth drives the increase in energy use. use-forecast-to-rise-57-from-2004-to-%2730http://www.reliableplant.com/Read/6509/world-energy- use-forecast-to-rise-57-from-2004-to-%2730
An increased dependence on energy imports means that the cost and supply of a vital resource for our economy slips further and further out of our control. Moreover, we may become more exposed to the results of political instability in the regions where fossil fuels are produced. Economic If present trends continue, increasing demand will cause rising imports of energy - in the EU.

the number of appliances and gadgets owned in the world increases daily, all needing energy. Economic Top 10 green gadgets Adam Vaughan profiles some eco-friendly options for gadget fans Source:
Economic So Stuff, Cars and Planes makes up 70% of energy use I am personally able to do something about. I need to be thinking more about "Stuff". Source: i-am-directly-responsible.htmlhttp://www.kennett.co.nz/paul/myonlinediary/2009/08/energy-use- i-am-directly-responsible.html
Underlying all these are needs for transport, cooking, heating, air conditioning and lighting. Economic 1. Set your thermostat lower:2. Dont heat the whole house: 3. Wash clothes with the Cold/Cold setting and use full loads 4. Adjust water heaters down to 126 degrees: 5. Unplug computers, TVs, Cable boxes, and other energy vampire appliances when not in use: 6. Turn off the lights when you leave the room 7. Take shorter showers: 8. Trim those bushes on the south side of your home & open the shades:
Economic The most reliable predictions indicate that by 2050, the world's population will have nearly doubled from its present level. It will rise from around 6 billion to about 10 billion people. Most of this growth, and much of the increase in energy consumption, will occur in LEDCs. All economies are increasing their demands for energy. This is especially true of newly emerging economies, especially the very large countries of Brazil, Russia, India and China (BRIC) where energy for manufacturing is the main growth.
Economic In order to be successful, all economies (including those already developed) need to grow each year. In one way or another, that growth needs energy.
Countries that experience a low level of development need to grow so that large proportions of their populations can rise out of poverty. Economic In 22 years, the US GDP has gone from about 20,000 to 35,000 per capita while energy use per capita has remained almost the same. Apparently it is possible for a country to increase the GDP without increasing energy use. Its also interesting that the US and the UK are the only two countries who are using energy so efficiently.

Entertainment, even staying at home and watching TV, requires energy. Social Consumers are becoming increasingly aware of energy efficiency, both for environmental and household budget reasons. Manufacturers are responding by finding ways to squeeze more energy efficiency out of their models.

Technological Growing international trade has led to the transport of goods by air, sea and all forms of land transport. The growth of maritime transport is strongly correlated with the growth of international trade. An increase of 3,8% in world output led to a strong increase in world seaborne trade in In 2004, global maritime transport reached 6,76 billion tons, meaning a growth rate of 4,3%.
