  • Policy and economic issues of electrical power and energy systems

    During the last quarter of the 20th century, many developments have served as catalysts for changes in the national energy policies of countries throughout the globe. These catalysts have affected the institutions and energy framework of virtually every country. In the majority of countries, the predominant electricity supply institution is the electric utility monopoly characterised by some ...

  • Environmental Profile of the Fossil Fuel Electric Power Generation Industry

    Introduction The EPA's Office of Compliance has developed a series of profiles or notebooks containing information on selected major industries. These notebooks, which focus on key indicators that holistically present air, water, and land pollutant release data, have been thoroughly reviewed by experts from both inside and outside the EPA. What will you find in this ...

  • Power quality issues and power electronics

    Harmonics in the distribution network have become an area of keen interest for utilities, power consumers and academic researchers due to its potentially disruptive impact on economy. This interest has lead to the development of a large number of standards that contain the problems as well as technological solutions to meet the specifications of the standards. In this paper, we discuss the ...

  • The Emerging Power of Microgrids

    Over many decades, the centralized power grid — a one-way flow of electricity, generated by large, remote power plants and distributed over miles of transmission lines to homes and businesses — succeeded in delivering electricity across continents to billions. But in recent years the system’s shortcomings have become increasingly ...

  • U.S. Nuclear Power in Decline

    Nuclear power generation in the United States is falling. After increasing rapidly since the 1970s, electricity generation at U.S. nuclear plants began to grow more slowly in the early 2000s. It then plateaued between 2007 and 2010—before falling more than 4 percent over the last two years. Projections for 2013 show a further 1 percent drop. With reactors retiring early and proposed ...

  • The flawed economics of nuclear power

    Over the last few years the nuclear industry has used concerns about climate change to argue for a nuclear revival. Although industry representatives may have convinced some political leaders that this is a good idea, there is little evidence of private capital investing in nuclear plants in competitive electricity markets. The reason is simple: nuclear power is uneconomical. In an excellent ...

  • The evolution of the topology of high-voltage electricity networks

    The electricity network represents an example of an evolving complex system. The first local networks contained only a few nodes, but within several decades, they have evolved into a highly connected continental system. The growth of these networks was influenced by various factors such as economic, demographic, political and technological developments. In this paper, we analyse the growth of the ...

  • Solar thermal power coming to a boil

    After emerging in 2006 from 15 years of hibernation, the solar thermal power industry experienced a surge in 2007, with 100 megawatts of new capacity coming online worldwide. During the 1990s, cheap fossil fuels, combined with a loss of state and federal incentives, put a damper on solar thermal power development. However, recent increases in energy prices, escalating concerns about global ...

  • Geothermal Energy... Power from the Depths

    The Earth's crust is a bountiful source of energy—and fossil fuels are only part of the story. Heat or thermal energy is by far the more abundant resource. To put it in perspective, the thermal energy in the uppermost six miles of the Earth's crust amounts to 50,000 times the energy of all oil and gas resources in the world! The word 'geothermal' literally means 'Earth' plus 'heat.' ...

  • As Global Demand for Electricity Grows, Geothermal Energy Heats Up

    January 9, 2017 — At 2:46 p.m. local time on Friday, March 11, 2011, Japan was rocked by the largest earthquake ever to strike its shores. The 9.1 magnitude quake triggered a devastating tsunami that killed more than 15,000 people. It also took out the back-up emergency generators that cooled the reactors at the Fukushima Daiichi nuclear power plant complex, causing a series of ...

  • Impact of frequency–based tariff in power market

    System frequency can be a useful signal in real–time power system operation to promote competition along with operational reliability. The commercial mechanism adopted in India, the availability–based tariff (ABT), defines a power tariff structure that allows recovery of capital cost and fuel cost as well as a condition–based price incentive to participants which help to minimise the real power ...

  • EPA targets electric utilities - the agency steps up efforts to manage coal ash damage

    Approximately 5.4 million cubic yards, or 1.1 billion gallons, of coal ash from the Tennessee Valley Authority (TVA) plant near Knoxville, Tenn., in December 2008 flooded some 300 acres of land, damaging property, polluting waterways, and killing fish. TVA will likely spend more than $500 million and perhaps as much as $1 billion dollars on the cleanup, says the U.S. Environmental Protection ...
