  • Capturing biogas energy to increase your business profits while safeguarding the environment

    Methane is a biogas produced from swine or cow manure, as well as food processing and meat packing waste. Methane is a natural gas, that when left uncollected, contributes to the harmful greenhouse gases in the earth’s atmosphere. When biogas is captured under a cover and becomes concentrated, it creates a corrosive and toxic byproduct called hydrogen sulfide. The gas generates a rotten egg ...

    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 ...

  • Mirrors in Space for Low-Cost Terrestrial Solar Electric Power at Night

    ABSTRACT — A constellation of 18 mirror satellites is proposed in a polar sun synchronous dawn to dusk orbit at an altitude of approximately 1000 km above the earth. Each mirror satellite contains a multitude of 2 axis tracking mirror segments that collectively direct a sun beam down at a target solar electric field site delivering a solar intensity to that terrestrial site equivalent to ...

  • Evils for giant power houses

    Giant Electricity Power Houses such as giant thermal power plants or giant nuclear power plants are established  either by governments by collecting tax from the people or by giant private companies by collecting huge money by way of shares of the company. In either cases, money comes from the people.   Giant  Electricity Power Houses give rise to giant ...

  • Power Inverter Basics

    Basic knowledge of power inverter Power inverter mainly adopts the PWM at present, controller switch to DC rapidly in a pulse-period to ensure that the DC integral value is equal to the sampling values of AC sine wave at the same time. After filtered, more than 96% sine wave output can be realized. Pulse inverter is self-excited inverter that output voltage is pulse modulation. This kind ...

  • Solving solar-power issues

    Certainly, no one would accept only having electricity during the day, and then only on clear days, if they have a choice. We need energy storage -- batteries. Unfortunately, batteries add a lot of cost and maintenance to the PV system. Currently, however, it's a necessity if you want to be completely independent. One way around the problem is to connect your house to the utility grid, buying ...


  • Power Positive Resource Recovery

    Using laws of thermodynamic analysis to evaluate the energy and power characteristics of wastewater and beneficial uses of biogas offers greater insight into best business practices and what is achievable. Growing numbers of waste-water treatment plants (WWTP) are striving to produce more power onsite. In recent years, there’s even been a race among WWTP operators to see who can ...

  • 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 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 ...

  • 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 ...
