Commercial buildings account for 19% of the energy consumed in the United States. Office buildings make up the largest sector of building type within the commercial sector, comprising 17% of all commercial buildings in the U.S, as well as 17% of the energy.
One success story is Ecopower, a Belgian cooperative that funds renewable energy projects. Funds are collected from members (the cooperative currently has 40,000), and invested in self-developed projects, like power plants running on vegetable oil or wind turbines. Shareholders can buy shares for $325 each, and each shareholder receives a vote in the cooperative's general meeting with profits for individual shareholders limited to 6%, because of its cooperative standing.
There are three primary areas where testing EV charging stations is critical - development, installation and maintenance.
Solar Energy Systems commonly used in Pakistan are Solar PV systems, Solar Water Heating systems, Solar Lighting Systems and Solar Pumping Systems. Generally the users do not appear to be satisfied with the solar system in use. Here we discuss what are the myths and realities causing dissatisfaction to users in Pakistan.
SGB's crop improvement platform is highlighted by aggressive breeding and selection via the largest, most diverse library of Jatropha genetic material in the world, and supported by the application of sophisticated genotyping and molecular breeding tools designed to shorten breeding cycles.
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.

Many 1.5 MW wind turbines use traditional open-loop water/glycol cooling systems. Regular water evaporation in the reservoir elevates the mixture's viscosity, prohibiting cooling of the IGBT and associated critical controls, causing the wind turbine to overheat unless serviced, which in turn means turbine downtime and high maintenance costs. Parker's KleenVent Coolant Evaporation Inhibitor (KV-CEI) is a simple add-on to the legacy cooling system, that eliminates water evaporation in the coolant solution and stops the ingress of airborne contaminants, by enclosing the cooling loop. The KVCEI also removes the need for continuous coolant monitoring during the warm season. Traditional maintenance calls to replenish or rebalance the fluids, take the wind turbine and transformer offline, resulting in significant downtime and revenue loss. Parker's cooling system solution optimizes wind turbine uptime and revenue, reduces maintenance costs and increases overall efficiencies.
