Energy development is a field of endeavor focused on making available sufficient primary energy sources and secondary energy forms to meet the needs of society. These endeavors encompass those which provide for the production of conventional, alternative and renewable sources of energy, and for the recovery and reuse of energy that would otherwise be wasted.

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

The Strongest Link in the Chain

Renewable energy—and solar energy in par­ticular—has a problem. Because it is subject to the vagaries of sunshine and wind for power generation, it is often not available when it is needed most. For those nighttime hours when the sun is not available and cloudy days when sunlight is minimal, provisions

The Costs and Benefits of Anaerobic Digesters

The Costs and Benefits of Anaerobic Digesters

Anaerobic digesters are a mature, proven technology. They take sludge, manure, and other organic waste materials and produce methane (natural gas) fuel. Nobody questions their technological capabilities. However, the question remains as to their economic benefits. In terms of dollars and cents, how much economic sense do anaerobic digesters make?

Living on an island with its limited footprint calls for creative solutions for handling solid waste. The efforts of Honolulu’s solid waste division—guided by Energy Recovery Administrator Wayne Hamada—earned SWANA’s 2016 Waste-to-Energy Gold Award. Over the years, one of two landfills closed, leaving the other and an incinerator operating, until
