Previously, studies of food production and consumption typically fell under the purview of research on health, agrarian studies, development sociology, agricultural economy, or social anthropology. Rural and natural resource sociologists especially have long emphasized the management and impacts of food production systems in their work. In classical tomes food was typically mentioned as an example of social classification or of social problems rather than a distinct object of study. Earlyst-century interest in food by both researchers and the larger public follows heightened awareness of the global character of markets and politics, concerns with health and safety, and the ways cooking and dining out have become fodder for media spectacle.
Forestimated world energy consumption was 5. By the end ofthe total installed electricity generating capacity worldwide was nearly 6. Inthe share of world energy consumption for electricity generation by source was coal at Coal and natural gas were the most used energy fuels for generating electricity.
Cogeneration CHP power stations use some of the heat that is otherwise wasted for use in buildings or in industrial processes. Recently there has been a large increase in international agreements and national Energy Action Plans, such as the EU Renewable Energy Directive, to increase the use of renewable energy due to the growing concerns about pollution from energy sources that come from fossil fuels such as oil, coal, and natural gas.
During this period, oil, coal, and natural gas continued to grow and had increases that were much higher than the increase in renewable energy. The following figures illustrate the growth in consumption of fossil fuels such as oil, coal, and natural gas as well as renewable sources of energy during this period.
The graph shows the ratio between energy usage and GDP for selected countries. GDP is based on purchasing power parity and dollars adjusted for inflation.
The data shows the correlation between GDP and energy use; however, it also shows that this link can be broken. The economic crisis is largely responsible for this slow growth. For several years now, the world energy demand is characterized by the bullish Chinese and Indian markets, while developed countries struggle with stagnant economies, high oil prices, resulting in stable or decreasing energy consumption.
Regional energy use also grew from to Intotal worldwide primary energy consumption wasterawatt-hours TWh or exajoules EJ. Inworld energy consumption decreased for the first time in 30 years by 1. Conversely, in OECD, consumption was severely cut by 4. Most energy is used in the country of origin, since it is cheaper to transport final products than raw materials.
Inthe share export of the total energy production by fuel was: The total solar irradiance is measured by satellite to be roughly watts per square meter see solar constantthough it fluctuates by about 6.
Fossil fuels range from 0. The total power flux from the sun intercepting the Earth is 5. If action is not taken beforeCO2 emissions would be locked-in by energy infrastructure existing in Patterns in Environmental Quality and Sustainability.
