Copy Machines Energy Consumption - How to use Photocopier Energy Saving Feature

Copy Machines Energy Consumption
The office copy machines (photocopier) is everywhere. Seven millions unit are in used in the United States and more than 1.5 million are sold each year. Anyone who has worked in an office has probably used at least once or perhaps spend hours making many copies. The copy machines are not cheap, not just the price. Office stencils related equipment is the fastest-growing use of electricity in commercial buildings in the U.S., according to the Department of Energy. The electricity consumed by office equipment companies will cost reaching two million dollar per year and copiers play an important role in this matter. (more…)

Printer Energy Consumption – How to use Printers Energy Saving Feature

Printer Energy Consumption
It is known that laser printers print faster, but swallow a large amount of energy, even if the printer is in the energy saving mode. Most inkjet printers work on the other side, with print speeds slower but consumes much less energy. Therefore, desktop laser printers have faster print speeds more than 40 ppm, published for the majority of energy used, while a multifunction inkjet printer print quickly you can pay a few pages the same period. So, how to measure the effectiveness of energy saving is measured printers? This can be determined on the basis of the energy consumption per printed page. (more…)

Monitor Energy Consumption (LCD and CRT Displays)

Monitor Energy Consumption
Green computing has forced even the largest companies to rethink and refocus to use energy more efficiently. We have low-power processors, motherboards, memory modules, hard drives and technology energy efficiency even higher. But still, there are many devices that need to be look at if they are efficient enough. You still need to look at each individual product like LCD and CRD monitor displays to decide whether their effectiveness in reducing your monthly electricity bills.

Most of the nation’s approximately 61 million monitors are associated with desktop PCs and workstations, whereas some 13 million displays rely on video input (as seen in airports). (more…)

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…)

Oil Prices Inflation Since the Early 1970s

Oil Prices Inflation
In the post-World War II period, until the beginning of the 1970s, oil price fluctuations were very small. From 1949 to 1970, average annual fluctuations of oil prices in U.S. dollars, as measured by the absolute value of year-to-year price changes, were of the order of 1%. Therefore, the real price (i.e., inflation adjusted) slightly declined throughout this period. This so-called Golden Age peak oil impacts period was characterized by a remarkable price stability and very strong gross domestic product (GDP) growth in the main industrialized economies. The stability of oil prices was an important element behind the low inflation and strong economic growth. (more…)

Income Tax and Energy Supply: Tax Codes Credit for Energy Production

income tax energy
Various provisions in the federal income tax treat energy producers more or less favorably than other businesses. By changing the after-tax rate of return on investments in the energy sector, the Tax Code may alter the long-run supply of specific types of energy.

In general, the income of all participants in the energy sector is subject to income tax of one form or another. Two notable exceptions arise in the generation and sale of electricity. Governmental agencies (such as the Tennessee Valley Authority, the Bonneville Power Administration, and municipally owned power companies) account for approximately 14 percent of the electricity sold in the United States.

Federal Excise Taxes to Motor Fuels: Gasoline, Diesel, Aviation Jet Fuel

Federal Excise Taxes
Federal Excise Taxes placed on specific energy sources tend to reduce energy demand for these energy sources in both the short and the long run. The federal government imposes excise taxes on almost all petroleum products (including petroleum additives) and coal (see Table 1). The federal government also imposes federal excise taxes on many transportation uses of methanol, ethanol, natural gas, and propane and imposes a fee on electricity produced from nuclear power plants and nuclear power electricity.

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…)

Electrodynamic Suspension (EDS): Technology Alternatives For Suspension And Propulsion

Electrodynamic Suspension
Electrodynamic Suspension (EDS) can be viewed as an array of magnets moving over a conducting sheet and being pushed upwards by forces due to induced currents. This electrodynamic suspension that was pioneered by Gordon Danby and James Powell in the 1960s, can not work at zero speed, but at higher speeds it can be inherently stable. The virtue of Electrodynamic Suspension designs is their ability to operate with larger air gaps than is feasible with Electromagnetic Suspension EMS designs. (more…)
