Brushing Up On Wind Turbine Maintenance Techniques

When it comes to turbine failure, many maintenance engineers will look towards the gearbox, electrics, or rotary blade, but often the cause of failure can be one of the least expensive components in the system, and one which should be relatively easy to replace - the carbon brush, which is situated inside the generator.

Gigantic Wind Turbines Signal Era of Subsidy-Free Green Power

Jess Shankleman , Brian Parkin , and Anna Hirtenstein for Bloomberg: Offshore wind turbines are about to become higher than the Eiffel Tower, allowing the industry to supply subsidy-free clean power to the grid on a massive scale for the first time.

10 Finalists Compete for Energy Storage Funding at Bright Minds Challenge

DSM launched this international competition last October with the goal of identifying the most promising solar and energy storage solutions that will contribute to the ultimate objective of producing 100% renewable energy for the entire planet.

Power Regulation and Pitch Control

Wind gusts can increase wind speeds at rates and for durations just long enough for the energy to enter the system, but sometimes too fast for conventional pitch control systems to respond adequately.

Using Shipping Containers to Construct a Biomass Recycling Facility

A Certificate of Occupancy on a building constructed of 60 Intermodal Shipping Containers is a huge accomplishment for Paul Wever, president of Chip Energy Inc.

Cellulose to Sugar (CTS) Technology for Ethanol Production

The CTS reactor creates a mechanochemical reaction within minutes and breaks down the cellulose to its base components of C5 and C6 sugars and Lignin. The sugars can then be fermented to create biofuels, fine chemicals, or a number of other items including pharmaceuticals, carbon fiber nanotubes, construction products, and nutraceuticals to name a few.

The Infrastructure Vision 2050 Challenge

Participants submitted written plans and supporting visual assets for a unique transportation system that improves upon current infrastructure to move people more quickly, sustainably and/or cost-effectively.

Can Sewage Solve Our Energy Crisis?

Sewage-to-energy would cut costs, and reduce greenhouse gas emissions. Industry calculations show that if all biosolids in the United States were converted into biomass energy, they would yield 7 million to 7.6 million megawatts of energy, while the existing capacity of wind power in the United States is approximately 43,000 megawatts.

Solar Energy DealReader: Q4 2016

Consolidation amongst producers as well as private equity and private investment in solar largely drove demand for solar deals.

Record-breaking solar panel converts more than a quarter of sunlight into electricity

Ian Johnson for Independent: A record-breaking solar panel that can convert more than a quarter of the sunlight it receives into electricity has been developed by researchers in Japan.

Tracking the Sun - A Growing Opportunity

Tracking is still relatively young -- the majority of deployments have really been in just the past few years -- but it's growing up fast.

Automation in the Energy Industry

Automation should be the prologue to a discussion whenever a new process is introduced, not a postscript. This fundamental shift in thinking is critical to maximize any automation strategy.

The Economics of Small Commercial Solar Projects

Solar projects can be a great investment for many businesses and offer a solid ROI, but it takes time and energy to put together a project that works for all the interested parties-the customer, the bank, and the installer.

The Atacama Desert, Extreme Conditions for Instrumentation

Due to extreme weather, high solar radiation, high UV index and the salinity of certain areas, the Atacama Desert in Chile presents conditions that contribute to the early degradation of instrumentation, communication and energy systems.

What Is Net Metering, and How Does It Work?

Depending on the size of your solar system and the amount of solar you produce each month, you can greatly reduce your monthly electric bills, and even profit from it.

US Battery - Solar RE L16XC Renewable Energy Battery

US Battery - Solar RE L16XC Renewable Energy Battery

Our batteries have Xtreme thick plates with (XC Diamond Plate Technology) added to them. They have been designed for hours of heavy discharge each day, followed by a fast recharge during the daylight hours. Very few batteries can take the grueling deep discharge-recharge cycle every day for long periods of time. U.S. Battery has proven time and time again that our solar battery line can stand up to this type of battery torture day in and day out for years to come. When you demand reliable energy storage count on U.S. Battery every time!
