Integration of pump storage hydro with wind energy
Renewable energy has significant advantages as it does not contribute to Greenhouse Gases (GHG). Wind energy is a renewable energy alternative that is being installed worldwide. However, wind energy is unpredictable and thus, unavailable as compared to conventional generation. The availability of wind energy compared to conventional power plants is a cause of contention. Currently, the rate of ...

A summary of wind power impacts on electric power system operating costs
Wind power plant output depends on wind speed. Such speeds cannot be accurately predicted over daily periods because the wind fluctuates from minute-to-minute and hour-to-hour. Consequently, electric utility system planners and operators are concerned that variations in wind plant output may increase the operating costs of the system. This concern arises because the system must maintain balance ...

Renewable Energy to secure our future
Clean energy is being talked about these years. From private blogs to various commercials, posters and mailings, people everywhere seem to be concerned about it. Even President Obama attached greater importance to a sustainable development than his predecessors. However, clean energy can refer to several subjects. What is clean energy referring to? How does clean energy benefit you? Does clean ...

Power curve measured and verified – Case Study
In 2010 RSE SpA (Energy System Research Inc.) within a Program Agreement with the Italian Ministry of Economic Development started a measurement campaign on a Libellula wind plant installed in Tuscany. The campaign lasted 1 ½ years and during this time RSE measured the turbine’s power curve following the requirements of the relevant IEC Standard ( EN 61400-12-1 – EN 61400-2). ...

Producing Green Hydrogen with Renewable Electricity
Hydrogen is an essential component of fuel cells. Sure, we all know that. However, did you know that all types of the gas are not created equally? Green hydrogen has gained a lot of momentum in renewable circles today. Hydrogen is produced by electrolyzing water. The process involves passing an electric current through water (under regulated conditions) to break its chemical composition. A ...

Asia-Pacific Analysis: Go green not nuclear
Crispin Maslog says the region should follow the Philippines' lead and focus on renewable, not nuclear power. A year after the Fukushima nuclear disaster, questions remain over the role of nuclear power in the developing world, including South-East Asia and the Pacific. Nuclear power had a renaissance, driven by rapidly growing energy demands, and fading memories of high-profile disasters at ...

Wind Energy Production Estimates: Moving Beyond Time Averages
No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

Clean Energy in Rural Areas
The environmental and economic benefits of clean energy have been well documented. However, not everyone experiences these benefits equally. As discussed in our July blog post, racial discrepancies have an impact on who is more likely to receive the benefits of clean energy, but geographic location also plays a role in determining who benefits. The five most populated counties in North Carolina ...

Coal-fired power on the way out?
The past two years have witnessed the emergence of a powerful movement opposing the construction of new coal-fired power plants in the United States. Initially led by environmental groups, both national and local, it has since been joined by prominent national political leaders and many state governors. The principal reason for opposing coal plants is that they are changing the earth’s climate. ...
