Wind Powered Engines And The Elusive 59% Efficiency

Images of the 3 bladed wind engines are now seen everywhere and they have come to symbolize intelligent energy creation for virtually everyone but are these designs actually the most efficient ones possible? No one seems to know their efficiency so that vital issue is completely overlooked and rarely discussed. Efficiency is important to all.

Geothermal Heat Pumps: Heating & Cooling of America

Greenhouse gas & energy are major problems for the future of America and Geothermal heat pumps are a great form of alternative energy has been around for over 30 years. Below are some facts about geothermal that you need to know.

Considerations in Fuel Cell Voltage Monitoring

Knowing what's happening inside a fuel cell is a critical function, especially as fuel cells are continuing to be developed. One important aspect of this is to measure the voltage of each cell in a stack. Although this may sound trivial, it can be more complex and more expensive than it may at first appear due to high voltages, high channel counts, communication types, etc. There are a few products commercially available that are designed specifically for fuel cell voltage monitoring.

Wind energy: Why is project certification so important?

What can you do as an investor to protect your wind farm investment? What can you do as a wind farm owner to secure your wind power production? How can the trust of insurance companies for wind farm projects be improved? The solution is to find an independent inspection, testing and verification company that combines technical consultancy with project certification.

Solar Repowering

REPOWERING, in general, can be defined as the set of changes aimed at increasing the power and therefore also increase the energy yield. The convenience of the repowering is in the benefits of technological modernization, which provides solutions for higher power and performance as the technology matures.

Asia-Pacific Renewable Energy Policy Handbook

GlobalData's report "Asia-Pacific Renewable Energy Policy Handbook" presents an in-depth analysis of the renewable energy policies across the major renewable energy markets in Asia-Pacific. It details the key policy instruments adopted by the major Asia Pacific countries in order to promote the deployment of renewables. The report provides the current and future renewable energy targets and plans along with the present policy framework, giving a fair idea of overall growth potential of their renewable energy industry. The report also provides technology specific support policies and measures used in different countries.

Phoenix Role in Prospective "Hydrogen Economy" - 2010 Outlook

A succinct-analysis of the increasingly widely discussed alternative and renewable energy universe serves to bring the Phoenix "Hydrogen Economy" initiative (with its REPLACEMENT energy status) into its special perspective.

Renewable Lean - The Need for Lean in Renewable Energy Manufacturing

Using Lean to produce renewable energy products will keep costs low, make the investment of capital more efficient, provide product in the shortest possible lead time, and ensure the continued growth of the industry. Using Lean will drive cost out of the products/processes allowing more conversion to renewable energy for every dollar spent. Some renewable energy manufacturing companies are using some Lean tools, but much more can be done to reduce the waste in manufacturing these products.

AltEnergyMag Interview - Electrical Energy Services and Renewable Energy

We believe that renewable energy services play to the strengths that we have developed in offering electrical and communications services to the commercial, industrial and residential markets. These renewable energy services are a very natural and logical extension of our traditional offerings.

AltEnergyMag Interview - Bio-based Solar Cell Backsheets

With over two decades of engineering, marketing, sales and executive management experience in high technology, BioSolar, Inc. Chief Executive Officer Dr. David D. Lee founded the company in 2006. An electrical engineer, Lee recognized that historically, manufacturing costs have been one of the biggest barriers to driving down the cost per kilowatt of solar energy for consumers. In response, BioSolar was the first company to introduce a new dimension of cost reduction by replacing petroleum-based plastic solar cell components with durable bio-based components derived from renewable plant sources.

The Next Generation of PV System Ownership: Moving from Passive Monitoring to Active Management

This article reviews the recent history of PV monitoring; the shift from single-meter systems to module-level control using highly reliable electronics, and future direction of the industry towards active system management from utility-scale solar farms down to the residential PV system.

Solar on a Stick: Bringing Solar to the Sun

One solar PV innovation has largely flown under the radar: pole mounted solar electric panels. That is, mounting solar PV panels on a steel pole anchored in cement, fully capable of adjusting to daily and seasonal sun positions.

GreenFasten™ solar panel roof mount hardware, watertight, USA made

GreenFasten™ solar panel roof mount hardware, watertight, USA made

The GreenFasten™ - GF1 system utilizes the patented watertight technology EcoFasten Solar® is known for. The flashing is fit with our EPDM rubber bushing and when used with a compatible EcoFasten Solar compression bracket (milled with countersink), a watertight seal is created, which protects the integrity of the roof. Requiring just a single fastener (lag bolt or self-drilling), GreenFasten provides the fastest install in the industry and will not void roofing manufacturer's warranties. Backed by IAPMO certification, GreenFasten delivers a mounting solution for all new or existing (retrofit) composition shingle roofs, and is the most cost-effective solution available. Like all of the solar roof mount solutions in our line of products, GreenFasten is made in the USA using recycled materials.
