Global Energy Consumption & Energy Demand in Electricity and Transportation

global energy demand
Global energy consumption in the last half century has increased very rapidly and is expected to continue to grow over the next 50 years. However, we expect to see significant differences between the last 50 years and the next. The past increase was stimulated by relatively “cheap” fossil fuels and increased rates of industrialization in North America, Europe, and Japan; yet while energy consumption in these countries continues to increase, additional factors are making the picture for the next 50 years more complex. These additional complicating factors include the very rapid increase fuel economy in energy use in China and India (countries representing about a third of the world’s population); the expected depletion of oil resources in the not-too-distant future; and the effect of human activities on global climate change.

UK Energy Demand: The United Kingdom Trends in Energy

uk energy demand
The long-term prospects for the U.K. economy are inevitably uncertain, and the most recent Department of Energy long-term projection puts forward three scenarios for the next 30 years with GDP growth rates of roughly 2.5, 1.5 and 0.5% p.a. The highest value corresponds to slightly less than the 1948 - 72 average, the central value is close to the long-run average over the last 80 years, and the lowest figure is similar to the performance during the current recession since 1973.

Personal Computers (PC) and Workstations Energy Consumptions

pc energy consumption
After lighting, personal computers (PC) and monitors have the highest energy use in office environments. Studies have shown that the power management of computers and monitors can significantly reduce the energy consumption per capita, saving hundreds or thousands of dollars per year in electricity costs. The energy consumption of computers and monitors will be needed by the amount of energy to work and how they are used is determined.

The installed base of approximately 71 million personal computers and 2.5 million workstations in 2000 consumed 17.4 and 1.8 TWh, respectively. (more…)

Oil Price Volatility as an Important Source of Inflation Changes

Oil Price Volatility
The volatility in oil prices since the early 1970s is a remarkable feature of energy economics. Annual fluctuations in the oil price level, as measured by the absolute value of year-to-year price changes, averaged only 1% in the 1949–1970 period; from 1970 to date, these fluctuations increased dramatically, reaching an order of magnitude of 30% per year. Even in the relatively stable period from 1986 to 1997, oil prices were more volatile than other primary commodities. (more…)

Peak Electricity Demand Impact and Reducing Power Needs During Peak Periods

Peak Electricity Demand
Power generation and distribution networks are built with spare capacity to meet peak periods of energy consumption is usually a time when demand for heating and / or cooling is particularly acute accommodate. Normally, peak electricity demand in some cases last just a few hours every year. And while the networks have always had to cope with peaks in recent years, the electricity consumption during peak hours has increased dramatically in the afternoon. (more…)

Energy Technology and Modern Urbanization

The age of industrialization came into full force through the modern exploration and use of fossil fuels. As one of its most striking phenomena, the rapid expansion of cities throughout the late 19th and the 20th centuries was a direct outcome of the fossil fuel energy economy as well. (more…)

Energy Consumption in the United States

energy consumption US
The gradual change in the energy consumption pattern of the United States from 1860 to 1990. In the mid-1800s, biomass, principally woody biomass, supplied over 90% of U.S. energy and fuel needs, after which energy biomass consumption began to decrease as fossil fuels became the preferred energy resources. For many years, a safe illuminant had been sought as a less expensive substitute for whale oils. (more…)

Pressure Relief Valves and Leaks That Damage the Environment

pressure relief valves
The pressure relief valves protect against the devastating effects of the overpressure. Unfortunately there are so careful with the environment and which are not always made leakproof, and can therefore be emitting harmful gases into the atmosphere continuously. While European directives aimed at reducing emissions of gases causing the greenhouse effect based on a share issue (linked to heavy fines for countries that fail), other solutions much easier go unnoticed.

Virgin Biomass as Source of Renewable Energy

virgin biomass renewable energy
The most widespread and practical process for capture solar radiation as organic fuels is the growth of virgin biomass. Extremely large quantities of carbon are fixed each year in the form of terrestrial and aquatic biomass. (more…)

Global Energy Consumption Statistics and Per Capita Energy Consumption

Per Capita Energy Consumption
The relationship of gross national product per capita to energy consumption per capita for most countries of the world correlates very well with the status of economic and technological development. The World Bank defines developing countries as low-and middle-income countries for which the annual gross national product is $5999 or less per capita (World Bank, 1989; U.S. Congress, 1991).
