“Smart grid” generally refers to a class of technology people are using to bring utility electricity delivery systems into the 21st century, using computer-based remote control and automation. These systems are made possible by two-way communication technology and computer processing that has been used for decades in other industries. They are beginning to be used on electricity networks, from the power plants and wind farms all the way to the consumers of electricity in homes and businesses. They offer many benefits to utilities and consumers -- mostly seen in big improvements in energy efficiency on the electricity grid and in the energy users’ homes and offices. For a century, utility companies have had to send workers out to gather much of the data needed to provide electricity. The “grid” amounts to the networks that carry electricity from the plants where it is generated to consumers. The key activities that comprise OE’s smart grid strategy are summarized below.

Grid or Off-Grid?Bob Bruninga, WB4APR If you have no access to the GRID, you have no choice, you have to go ... off-grid! But if you have the grid and are considering going off-grid or using batteries for any reason, please review this page and also join our discussion group. Click to join SolarDIY Download Solar Presentation given at the 2011 TAPR/AMSAT dinner at Dayton. Staying on-grid can give you nearly triple the power for about the same cost and avoid battery maintenance for the rest of your life. Costs are so low you can now buy a DIY 3.7 kW system from COSTCO for $13,500. Here are some other web pages related to my experiences with home solar power:
Energy, Environment and ResourcesThe Energy, Environment and Resources department, led by Bernice Lee , conducts high-level research on critical issues of energy security, environment and resource governance. Latest: US Energy: the New Reality There is undoubtedly a US energy revolution under way – but where that revolution will lead is not yet clear. Combating Illegal Logging Duncan Brack considers the compatibility of efforts by consumer countries to reduce illegal logging with World Trade Organization rules. The Trouble with Biofuels Agricultural biofuel use increases the level and volatility of food prices, with detrimental impacts on the food security of low-income food-importing countries, says this new paper. Resource Insecurity The outlook is one of supply disruptions, volatile prices, accelerated environmental degradation and rising political tensions over resource access, warns this new report.

Enevate - Innovating Energy StorageEcodesign - Sustainable and responsible business - Enterprise and IndustryThe Ecodesign Directive provides with consistent EU-wide rules for improving the environmental performance of energy related products (ERPs) through ecodesign - brochure [2 MB] . It prevents disparate national legislations on the environmental performance of these products from becoming obstacles to the intra-EU trade. This should benefit both businesses and consumers, by enhancing product quality and environmental protection and by facilitating free movement of goods across the EU. Energy related products (the use of which has an impact on energy consumption) account for a large proportion of the energy consumption in the EU and include: Energy-using products (EUPs) , which use, generate, transfer or measure energy (electricity, gas, fossil fuel), such as boilers, computers, televisions, transformers, industrial fans, industrial furnaces etc. Contact: ENTR-Ecodesign@ec.europa.eu and DG Energy, energy efficiency unit
Firefly International EnergyEfficient energy useA spiral-type integrated compact fluorescent lamp , which has been popular among North American consumers since its introduction in the mid 1990s. [ 1 ] Efficient energy use , sometimes simply called energy efficiency , is the goal to reduce the amount of energy required to provide products and services. For example, insulating a home allows a building to use less heating and cooling energy to achieve and maintain a comfortable temperature. Installing fluorescent lights or natural skylights reduces the amount of energy required to attain the same level of illumination compared with using traditional incandescent light bulbs . There are various motivations to improve energy efficiency. Energy efficiency and renewable energy are said to be the twin pillars of sustainable energy policy [ 4 ] and are high priorities in the sustainable energy hierarchy .

Creating a Microgrid Energy Management System Using NI LabVIEW and DAQ - SolutionsAuthor(s):Cheah Peng Huat - 南洋工科大学 Siow Lip Kian - 南洋工科大学 Liang Hong Zhu - 南洋工科大学 Vo Quoc Nguyen - 南洋工科大学 Nguyen Dinh Duc - 南洋工科大学 Gooi Hoay Beng - 南洋工科大学 Students at the Laboratory for Clean Energy Research (LaCER) in the School of Electrical and Electronic Engineering (EEE) at Nanyang Technical University (NTU) created a microgrid prototype. It consists of energy resources such as solar photovoltaics (PVs), wind turbines, fuel cells, and battery banks. The entire microgrid is controlled by the Web-based MEMS server, which controls and monitors different aspects of power management. We developed software programs to manage information collected from the sensors and perform load control and generation dispatch. Figure 1 shows the interface diagram between the database and different software modules. Advanced Sensing and Communication System The microgrid testbed uses a programmable AC source to test the stand-alone microgrid. Load Forecasting Unit Commitment State Estimation
