After conducting an initial site survey and identifying the ideal area for a solar PV system, One Stop Green, an online retailer for energy efficient products and installer of solar systems for residential and commercial properties, has completed the installation of a 2.5kW Solar PV and Solar Thermal system for hot water, which includes the expansion for additional modules.
Beginning in late 2011, One Stop Green was contacted by a homebuilder who was interested in making a new home they were building in Alexandria, Virginia, entirely green and energy efficient. One Stop Green sent out a sales associate who walked the homebuilder through the entire process beginning with a site survey when the home was still in the phase of construction. From there, One Stop Green worked with the homebuilder to determine a budget and identify those items that are most important to the eventual owner of the home. The homebuilder was aware that energy prices will steadily continue to rise and a small solar PV system in conjunction with a solar hot water system to provide hot water for the home would help to mitigate those high electricity costs.
After working to prioritize the homebuilder?s requests, One Stop Green developed the plans for a 2.5kW system that would produce approximately 3,991 kWh annually, or about 40% of the home?s energy usage along with a solar thermal package that would provide hot water for the entire home. Because historic consumption rates we?re not available, One Stop Green used surrounding homes to determine consumption rates and estimate power production that will offset electricity usage. As panel prices become cheaper and more incentives become available in this area, the homebuilder wanted to give the option to the eventual homeowner to be able to expand their system, which is why One Stop Green installed additional flash mounts so as to prevent unnecessary work associated with installation of more modules. The homebuilder was so happy with the overall install of the solar PV and hot water systems ? the first in the neighborhood, and potential to save money for the homeowner on their energy bills that they have asked One Stop Green to return once construction is complete to offer additional products such as energy saving LED light bulbs, water saving toilets, faucets, and rain water harvesting systems to make this home as energy efficient as possible.
One Stop Green, LLC facilitates environmentally friendly improvements to residential and commercial properties through distribution of green, energy efficient products and services. They offer every product needed for sustainable energy independence enabling homeowners, businesses and commercial property owners to master their usage by reducing waste and implementing efficient energy consumption methods. Their goal is to provide user friendly and practical long-term solutions to existing inefficiencies and their carefully selected products and professional installers offer a higher level of satisfaction and service for their customers.

Nuclear power is facing a number of challenges in the close to and long-term. Despite the development of new reactor designs, the possibility of a catastrophic accident has not been eliminated. In addition, the vulnerability of nuclear power plants to terrorist attacks further increases issues about nuclear power safety.Nuclear Power Safety 2011 will address a broad scope of multidisciplinary issues connected to technological advances in nuclear power safety. The understanding of such issues and their interrelationship is vital to the development of safer nuclear power. This plan will bring together an international interdisciplinary panel of specialists from government, academia, and industry to address vital concerns in nuclear power safety such as:
Lessons learned from Fukushima, Chernobyl and Three Mile Island
Identifying and overcoming vulnerabilities to terrorist attack
Safety systems ? a technology neutral assessment
New technologies – impact of novel supplies, technologies and advanced engineering on threat mitigation
Technologies failure vs. human factor vs. all-natural disaster
Safety culture and human errors
Nuclear power plant regulation: implications of a safety objectives driven efficiency-based regulation
The “Nuclear Power right after Fukushima: Issues and Possibilities” keynote address will be delivered by Dr. Gail H. Marcus. Dr. Marcus will offer an overview of how the Fukushima accident has altered nuclear power operations and development about the globe. Some of the significant safety issues raised by this incident will be identified, and probably impacts on operating plants will be explored. Particular attention will be given to identifying achievable technologies options to help address longer term nuclear power development plans. Dr. Marcus is an independent consultant on nuclear power technology and policy and previously worked as Deputy Director-Common of the OECD Nuclear Energy Agency in Paris Principal Deputy Director of the DOE Office of Nuclear Energy, Science and Technology in different positions at the Nuclear Regulatory Commission and as Assistant Chief of the Science Policy Research Division at the Congressional Investigation Service. Dr. Marcus has served as President of the American Nuclear Society and as Chair of the Engineering Section of AAAS.
