Geothermal energy is the heat from the Earth. It’s clean and sustainable. Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth’s surface, and down even deeper to the extremely high temperatures of molten rock called magma.

Software: Optimizing Operations

For commercial, industrial, and institutional power consumers with a heightened need for affordable, reliable, and resilient power supply, advanced microgrids can provide not only control over power sources and energy costs, but also “green” energy and peace of mind. Microgrids employ a wide range of onsite generation resources, along with

The Physics of CHP Cogeneration and Heat Engine Efficiency

The Physics of CHP Cogeneration and Heat Engine Efficiency

How does CHP work? To understand CHP you have to begin with the Carnot cycle, and how it describes the function and efficacy of any heat engine. The thermodynamic Carnot cycle (proposed by Nicolas Carnot in 1824) is a four-stage process that describes the reciprocal operations of a heat engine

Mitsubishi Hitachi Power Systems Sponsors the Emissions Index for US Power Sector

Mitsubishi Hitachi Power Systems (MHPS) and Carnegie Mellon University (CMU) today announced the creation of a new index that will measure carbon dioxide emissions from the U.S. electrical power generation sector. The Carnegie Mellon Power Sector Carbon Index will

IAPMO Seeks USEHC Geothermal Piping and Photovoltaic Task Group Members

IAPMO Seeks USEHC Geothermal Piping and Photovoltaic Task Group Members

The International Association of Plumbing and Mechanical Officials (IAPMO®), publisher of the Uniform Solar Energy and Hydronics Code (USEHC), is accepting applications and seeking technical experts to participate on task groups relating to geothermal piping and photovoltaic systems.

The scope of the Geothermal Piping Task Group is to review Items 97,

Zero Energy Schools

Zero Energy Schools

Buildings account for nearly 40% of the nation’s energy use. Why does this matter? Because it means that while buildings are a big part of our energy challenge, they also have the potential to be a major part of the solution to a clean energy future. That’s why the US

HVAC Innovations

HVAC Innovations

Efficiency is the buzzword for innovations in HVAC technologies. “Government mandates are requiring higher efficiencies overall from the building, which includes everything from the HVAC all the way to the glass in the door,” points out Steve Ulm, spokesperson for SEMCO. “Efficiency is driving the construction industry as a whole.”

Integrating CHP with Microgrids

Integrating CHP with Microgrids

While combined heat & power (CHP) may not be appropriate for integration into all microgrids, it definitely does have its place in a lot of them.

CHP systems output heat (or cooling), as well as electricity, primarily as a topping cycle. “The prime mover is typically a reci­procating engine or a turbine,”
