Energy Efficiency – Home Appliances

Though often taken for granted, home appliances exist to allow us to operate more efficiently on a day-to-day basis. And, though not critical to our well-being, they definitely save us time and labor, but questionable as to whether they save us money. Even those refrigerators, microwaves and dishwashers that come with energy and money-saving features need to be operated properly if one is to...

Introduction to Micro Grids

Plug-in Hybrid Electric Vehicle With the increased importance of electricity in our day-to-day lives and overall economic prosperity, the notion of depending on outdated, centralized power grids that inefficiently deliver power and occasionally fails to meet basic needs for power may be insufficient, if not outdated. This has brought about the application of localized power grids, as part of an...

Introduction to Ocean Power

Ocean Power The scientific community remains intrigued by the prospect of harnessing the energy of the ocean, if for no other reason than the fact that oceans covers over 70 percent of the earth’s surface. A few successes have been experienced in this area: Tidal power plant in France, designed to produce 240 MW, which is larger than a typical wind farm and about 30-50 percent of the capacity...

SmartGrid and Renewable Energy: The Unresolved Questions

Wind Turbine Farms As the electricity industry forges ahead in defining and ultimately implementing SmartGrid and transitioning to a supply portfolio that includes renewable energy sources, there are a number of unanswered questions and obvious objections that must be confronted to ensure the full benefits of improved reliability, increased energy efficiency, and reduced CO2 emissions.  These...

The Inevitability of Smart Grid

Expansion of Driving Forces Point to Smart Grid Wind Turbine Farm Much of the current industry discussion around Smart Grid tends to focus on its benefits related to improved environmental stewardship through energy conservation and the introduction of renewable energy resources. Although these benefits will have a permanent role in the overall business case for Smart Grid investments, there are...

The Smart Grid Defined

Smart Meters-AMI One of the more commonly used yet least understood terms in today’s electric utility vocabulary is the term Smart Grid. Much like other often-used terms, with broader use it now lacks any precision, particularly given the evolution of many related programs and initiatives. Virtually every presentation on the topic starts with a definition of what Smart Grid is relative to the...

Demand Response-Opportunity and Value

The Energy Independence and Security Act of 2007 specified that the Federal Energy Regulatory Commission (FERC) determine the potential for demand response defined as: The ability for customers to change their electrical usage based on changes to price of electricity or in response to incentive payment programs, designed to encourage use of electricity during periods of lower demand. The desired...

LED Streetlights

Streetlights are an important public safety service that is expensive to maintain and consume a significant quantity on energy. Consequently, a number of U.S. cities, most notably Los Angeles and Pittsburgh, are embarking on programs to convert traditional street lights to light emitting diode (LED) lighting. These LED lighting systems are attractive because they: Do not consume as much...

Spray-on Solar Panels

Solar Panels According to the National Renewable Energy Laboratory (NREL), by 2020 photovoltaic (PV) technology will represent 15 percent of the energy consumed in the U.S. and the National Center for Photovoltaic (NCPV) expects that 10 percent of the power produced during peak times will be by solar energy. Solar energy is plentiful, clean, and renewable. In fact the amount of energy provided by...

Smart Grid – Driving Forces and Benefits

Electric Transmission Infrastructure Electricity provides over 40 percent of the overall energy consumed in the U.S. and it has a well-established relationship to GDP growth. Consequently, the strength and resilience of the electric grid is a matter of critical importance to the overall economy. The current U.S. electric transmission and distribution grid is generally considered to be aging,...
