    Greater complexity along with variables implies greater risk of power outages, and potentially more substantial impact of power outages as well, as one would expect structural dependency on power to increase enormously under a Smart Grid Scenario.

    In a world of hurricanes and super storms people are increasingly becoming aware of the need for a collective action towards a sustainable and clean future. Electricity generation (and consumption) is one of the major causes of greenhouse gas emissions and provides immense opportunities for innovation and improvements. One might wonder of the options that an electricity customer can have in order to contribute towards reduction of carbon footprint. It is here that 'Demand Response' comes into play.

    With the recent 60 Minutes TV profile of Daniel Day-Lewis, who so powerfully portrayed our most popular US President in the 2012 bio-pic 'Lincoln', we continue to examine the emotion and pain of the Civil War.  With President Obama's SOTU address, we're reminded that the nation remains essentially at war over the development and delivery of energy.  The battles to decide our most economically and environmentally sustainable path forward are being waged in legislative chambers, courtrooms, town halls and countless media channels and editorial pages.

    Utility companies are under increased pressure to build new infrastructure that will drive better performance and returns for decades. Recent natural disasters have brought this issue to the forefront but it requires capital. According to Booz & Company, "Capital expenditure requirements across the U.S. utility industry are expected to exceed US$100 billion annually through 2020. This represents an increase of 100 percent over the annual costs of the early 2000s, according to Edison Electric Institute."

    Over the last decade and a half, technology and innovations have had great impact on Outage Management Systems (OMS). The latest OMS is much more robust, uses web technologies, integrates with more Information Technology (IT) and Operational Technology (OT) systems, contains more tools, supports special device types, and communicates with Smart Grid enabled networks. While they were never simple systems, the capabilities of OMS continue to grow. Early OMS implementations contained configurations custom to their deployment.

    On January 23, 2013 Duke Energy announced that it had completed the Notrees Battery Storage project in Texas which now represents the largest capacity battery facility in North America. Providing backup power for the Notrees Windpower project, this facility is able to produce 36 MW of power on demand whether or not the wind is blowing.

    The St Lawrence River has for decades served the needs of the energy and transportation sectors. Ships have carried towers and turbine blades for the wind energy sector, while a new hydroelectric installation is being completed on the Canadian side of Niagara Falls. The waterway is home to several hydroelectric power installations and it serves as the heat sink for several coal-fired and nuclear-thermal power stations as well as 3-ethanol plants.

    The variable operations of weather-related Distributed Energy Resources in distribution systems cause voltage fluctuations at different buses of the distribution circuits. These fluctuations may significantly impact the power quality as well as the reliability of other volt/var controlling devices. Compensating changes of the DER reactive power may be used to mitigate these voltage fluctuations. This paper discusses two methods of such compensation, compares them in terms of a number of operational criteria, and presents an illustrative numerical example.

    Thermal standards for homes were established to improve thermal performance by strengthening the barrier between outside and the conditioned interior. A checklist of thermal standards is included in the energy code. For example, wall insulation in Oregon has to be rated at least R-21. A building inspector verifies compliance for each component of the thermal shell: foundation, underfloor, walls, roof, skylights, doors and windows.
