Wind and solar electricity cannot supply more than 10 per cent of electricity on the world's electricity grids.
Fusion power has long been recognized as a clean source of energy. Unfortunately, after over 50 years of research, scientists don't expect a demonstration of full-scale fusion power generation in a prototype power plant until after 30 to 35 years. Extensive research, however, has made two significant advances in plasma physics, the discovery of bootstrap current and plasma's ability to organize it...
The number of components used in system-on-chips (SoCs) is increasing dramatically as designs move into 90/65nm technologies and ensuring proper delivery of power to all the components is becoming much more difficult. There is a new technology that designers can use to sign-off the structural Integrity of the power grid early in the process, before proceeding with any power consumption, voltage drop or electromigration simulations. The technique is similar to formal verification, where assertions can be proven independent of vector stimulus.
The paper discussed carbon footprint and carbon emission calculator. A carbon footprint is defined as the total amount of CO2 and other greenhouse gases emitted over the full lifecycle of a product or service.
This paper examines how far the impact of renewable energy can be realistically predicted over the next 10 years considering the current off-the-shelf renewable energy technology, rising electricity consumption and inflation in raw material feedstocks.
St Johns River Power Park (SJRPP) in Jacksonville, FL, consists of two coal-fired Foster Wheeler drum boilers and two General Electric turbine generators, each with an output of 640 MW. The boilers are able to burn a wide variety of coals from all over the world, and they can burn up to 20% petroleum coke. This paper discusses how the pulveriser upgrades at the Florida generation site cleared the ...
Turkey experienced a strong economic recovery after a financial and currency crisis in 2001 that led to severe economic contraction. In March 2001, the Turkish government enacted a new electricity market law, which sets the stage for liberalisation of power generation and distribution activities. Under the law, the state-owned Turkish Electricity Generation and Transmission Corporation (TEAS) was split into separate generation, distribution, and trade companies, with a goal of eventual privatisation of the generation and trade companies.
National Grid has divided the country into four regions and awarded Alliance contracts to manage and upgrade the transmission grid.
Fusion power has long been recognized as a clean source of energy. Unfortunately, after over 50 years of research, scientists don't expect a demonstration of full-scale fusion power generation in a prototype power plant until after 30 to 35 years. Extensive research, however, has made two significant advances in plasma physics, the discovery of bootstrap current and plasma's ability to organize itself in the edge at certain a pressure so that it is a much better insulator and retains heat much better. These advances have been very helpful in the development of the experimental fusion reactor ITER.
Wind power in Russia is certainly lagging behind many other European countries, but, with the rising cost of energy, the case for its adoption is growing. For Russia to develop its wind power industry effectively requires clear scientific, industrial and organisational cooperation to deal with wind power resources estimating and turbines production and large-scale wind farm projection. it requires...
At a recent Platts Nuclear Energy Conference in Prague, Power Engineer caught up with Roland Kobia, member of cabinet for the European Commission, to talk to him about the recent EU energy policy and, of course, the future for nuclear energy in Europe.
Wind power in general has a bad reputation for intermittent power, so perhaps it is understandable that many onlookers have a problem with low-wind sites for wind farms. But as the author explains, that attitude is misguided.
Up until now, almost all network-compatible terminal equipment has taken in its power via a mains power supply unit (PSU) plugged into a nearby socket. Things can be made far simpler with Power-over-Ethernet (PoE). Using this technology, it is possible to deliver power supply to network-compatible terminal through the same structured cable as the Ethernet connection from a centralised power supply unit in the comms closet or floor distributor. Combined with uninterruptible power supplies in the comms room, this not only ensures greater operating reliability, it also facilitates the installation of WLAN access points or IP video cameras in previously inaccessible places. This means that companies benefit both from simplified installation and from the improved range of their WLANs.
Peter Stratford, Principal Consultant at BMT Renewables looks at how satellites orbiting hundreds of kilometres above the Earth can help wind farms to get built.
HVDC stands for High Voltage Direct Current, a well-proven technology used to transmit electricity over long distances by overhead transmission lines or submarine cables. It is also used to interconnect separate power systems, where traditional alternating current (AC) connections cannot be used. The reasons for selecting HVDC instead of AC for a specific project are often numerous and complex. The most common arguments in its favour are: lower investment cost, longdistance water-crossing, lower losses, asynchronous interconnections, controllability, limited short-circuit currents and environment.
Following on from Al Gore's box office success 'An Inconvenient Truth' comes a yarn about our reliance on the dwindling resources of oil.
This paper presents the use of concentrating solar power technique. It can be used as an important method of creating carbon-free electricity. CSP is currently the most cost-effective way of capturing solar energy, but this might change in the future with further developments in photovoltaics (PV). The paper outlined several variations on the scheme, including systems that use heat to drive a Stir...
