Grand Opening of World's Largest Hospital SolarWall¨ (solar air heating) System

The largest hospital SolarWall¨ system in the world was installed at Cambridge Memorial Hospital (CMH). Totalling over 10,000ft2 in size (spread over 3 sections) the CHM SolarWall¨ systems will reduce the traditional heating load by using the sun's energy to preheat the incoming ventilation air.

ACORE-EPRI Paper Identifies R&D Requirements for Expansion of Renewable Energy

The paper identifies the challenges facing wider use of renewable energy in the U.S. It encompassed wind power, solar energy, bioenergy, geothermal energy , hydropower, tidal, wave and other ocean power, and waste-energy resources across all application sectors.

Nissan Rolls Out Electric Car

Nissan Chief Executive Carlos Ghosn drove quietly out of the Japanese automaker's soon-to-open headquarters Sunday in the first public viewing of its new zero-emission vehicle. It was the first time the external design was shown of Nissan Motor Co.'s environmentally friendly electric automobile, set to go on sale in Japan, the U.S. and Europe next year. Nissan has promised that the Leaf, which goes into mass-production as a global model in 2012, will be about the same price as a gas-engine car such as the 1.5 million yen ($15,000) Tiida, which sells abroad as the Versa, starting at about $10,000.

A Big Wind...

Each wind generator, each solar farm absolutely requires a stable grid to feed into and are not and can not be prime power sources. Meters record the amps passing thru the transformers which connect the wind units to the grid, but very little real power goes very far (see notes on AC power). They are simply dispersed, independent power producers which cannot supply any load without the base loading power of coal or natural gas. In truth, not one ounce of coal, programmed to be burned in a coal fired power system has ever been offset by the introduction of wind or solar power into the grid.

AltEnergyMag Interview - AWEA Small and Community Wind Conference & Exposition

AWEA has created their first Small & Community Wind Conference & Exhibition to bring together industry leaders, new entrants, project developers, economic development groups, municipalities, land owners and other allied organizations to formulate and enact growth strategies for small and mid-sized wind applications. Focusing on important topics such as national renewable energy legislation, technology costs, zoning requirements, utility interconnection, tax revenues and investment opportunities, this conference offers valuable information on how best to capitalize on wind technology.

AltEnergyMag Interview - Home Control and Energy Savings

Watteco, a System on Chip (SoC) manufacturer has developed a unique Power Line Communication solution for the Smart Energy Command & Control Market (Home Control and Street Lighting). This technology meets today the future market requirements in term of Low Power, Small Size and Low Bill of Material.

AltEnergyMag Interview - Waste-to-Energy

With over three decades of experience, Jack Ristau has been a driving force in developing, constructing, and operating municipal infrastructure facilities, including solid waste management and energy recovery projects, in the United States and overseas. Since joining Wheelabrator in 1984, he has developed many notable resource recovery business activities as well as directed several projects in the Far East, Mexico, Turkey, United Kingdom, Puerto Rico, the Bahamas, Jamaica, and Barbados. Currently, Ristau is director of business development and manages waste-to-energy project opportunities in the United States and Canada, supervising proposal development and customer contract negotiations. Prior to joining Wheelabrator, Ristau held project management positions at MITRE Corporation, Hayden, Harding and Buschanan Engineers, Inc., and Metcalf and Eddy, Inc. Ristau holds a Bachelor of Science degree in Engineering from Penn State and a Masters of Science degree in Industrial Management from Northeastern University.

Biomass Wastes

Biomass wastes can be transformed into clean energy and/or fuels by a variety of technologies, ranging from conventional combustion process to state-of-the art thermal depolymerization technology. Besides recovery of substantial energy, these technologies can lead to a substantial reduction in the overall waste quantities requiring final disposal, which can be better managed for safe disposal in a controlled manner while meeting the pollution control standards.

Coal Ash Safety Issues

In December 2008, the 84-acre coal ash surface impoundment at the Tennessee Valley Authority's (TVA) Kingston coal-fired power plant failed and released over a billion gallons of coal combustion waste. It's estimated that this release could ultimately cost a billion dollars to remediate because 300+ acres were covered by the flood of coal ash slurry. At question is does the U.S. need more traditional coal-fired power plants and what to do with the ash slurry mess?

Fuel Cells Give New Meaning to "Green Grocer"

Some major chains have turned to fuel cell technology to help reduce their carbon footprint and their dependence on the electrical grid. Fuel cells provide clean, quiet, and reliable power to an industry that cannot afford to experience electricity outages. Stores are using fuel cells to generate heat, hot water, electricity, and even to power vehicles.

It is Time to Cool it With Wind.

The goals of the stakeholders of the wind industry are often seen as conflicting: Utilities and some customers argue that wind power is too expensive. The wind industry and environmentalists argue that the current fossil generation does not pay for the right to pollute and if they did, wind would be cheaper than other sources of power. To both it is time to cool it.

It's Time to Bring Renewable Energy Home

In a unanimous vote, the Public Service Commission (PSC) recently cleared the way for Alliant Energy's Wisconsin utility to construct a 200 megawatt (MW) windpower plant project in southern Minnesota. Once operational, the Bent Tree project, costing upwards of $450 million, will be a productive source of renewable energy that will provide lasting benefits to Minnesota's economy and environment. Since it will be Alliant's Wisconsin customers who foot the bill, however, it is reasonable to inquire whether the current utility practice of outsourcing renewable energy production to other states is a good thing for Wisconsin's economy.

Keep Cool with a Solar Attic Fan

Solar powered attic fans are cool! Having worked in attics for many years installing solar water heaters I know all too well how hot they get. I've measured 140 degrees F! Most homes have manual roof vents, which allow some nominal air movement, but they can't keep up with the sun pounding down all day.

My Geothermal Home Sweet Home

My long and winding path through the selection of the best heating and cooling system began six months ago and culminated with the selection of a geothermal system, which is right for us for so many reasons.

LG Solar Unveils NeON R with Enhanced Aesthetics and Energy Savings

LG Solar Unveils NeON R with Enhanced Aesthetics and Energy Savings

The NeON R module features "Back Contact" cell technology delivering an entirely black panel that is aesthetically pleasing and energy efficient. The cell's seamless, surface blends perfectly into nearly all rooftop designs while the module's electrodes are positioned on the rear of the cell. Using LG's N-type cell structure, the panels produce 365W of energy, up to 7.3kWp, compared to 5.8kWp of the p-type cell. The module's new design minimizes LID, thereby delivering a longer lifespan and increased energy output.
