Storage should be a net cost savings. For example, the cost of frequency regulation is less (on margin) using storage than using a thermal plant. The PJM Performance-Based Regulation market, operational since October 1, 2012, has demonstrated that using fast and accurate energy storage resources has and will lower the total need for frequency regulation, in which should result in overall lower costs to consumers.
The greatest challenge for backsheet manufacturers is to develop product that meets strict performance requirements and industry standards, at a time when there is increasing pressure to reduce costs.
Here's an interview with economist Ed Dolan who lets us in on a few secrets about oil prices, the prospects for cheap energy, Russia's growing uncertainty and how the natural gas boom is hindering renewable energy efforts. Contributed by Oilprice.com
Here are 4 diversified project case studies illustrating how small wind systems can make a difference.
The exceptional operational safety and ease of use are important criteria for the installation on Star Island, because technical support here usually is not available at short notice.
The rooftop installation consists of 2,200 panels producing approximately 650KW annually. The funds received are credited to the Jamieson utilities account and are offsetting almost 20% of the electricity bill.
Hanwha has the development capital and balance sheet that financiers look for in a partner. This is a tremendous differentiator given the current market conditions.
Women as a group are the most powerful communication vehicle in the world. When women believe in something, they spread the word faster and more effectively than any advertising can. When it comes to buying power and buying power: They rock.
AltEnergyMag had a residential PV system installed and is monitoring the process as well as the performance. This is part 2 of a series of articles we will publish along the way in order to demonstrate and explain a real world project for our readers to follow and learn from.
Europe's electricity demand is increasing. In the context of Europe's decarbonisation goals, this power will have to come from more variable Renewable Energy Sources. As European policymakers consider their options for invesments in new and more efficient grid infrastructure, they should take into account the benefits that PV is already producing and, more importantly, plan for the greater benefits it is capable of producing in the future.
The dataset is designed to provide realistic energy production profiles based on wind variability, both for the existing fleet as well as large expansions thereof. One of the main concerns with wind energy is that it is variable, with energy produced only when and where the wind blows.
Compared to other mechanisms that convert chemical energy into electricity, the fuel cell, specifically the solid oxide or ceramic fuel cell, is the most efficient.
With the solar energy industry reporting that the second quarter of 2012 was the second largest quarter in history, there was "tremendous enthusiasm and vitality running through the entire solar industry value chain," said Rhone Resch, president and CEO of SEIA.
TeamSustain designed a 65kW battery-based PV system for Spice Village. The system was designed to support the full load of the resort after implementing the energy efficiency measures identified in the energy audit. With the new PV system, the resort will generate enough solar electricity to meet 100% of its power needs.
Green Banks are essentially clean energy finance banks formed at the federal or state level that operate as public-private financing institutions with the power to raise capital to support clean energy projects through loans and loan guarantees.

In the monitoring of large photovoltaic (Utility Scale), in assessing potential sites (Solar-assessment), or in up and coming electricity cost saving initiatives projects (Commercial & Industrial), the WS510 now provides the market a secondary standard pyranometer, ultrasonic wind speed, ultrasonic wind direction, temperature, pressure and humidity all in a single unit.. This sensor meets the high demands of the world meteorological organization (WMO) through the active valving at air temperature measurement and the inertia- and maintenance-free measurement of wind speed and wind direction on the ultrasonic principle. Equipped with a Kipp & Zonen pyranometer of the secondary standards, the WS510-UMB Compact weather sensor from Lufft unites the precision of a variety of meteorological individual sensors in a single all-in-one device, for the first time.
