Rethinking Solar Farms for the 21st Century: Tapping Ocean Space
09/15/14, Lee Hsiu Eik, Research Engineer, Offshore Engineering Centre, PETRONAS Institute of Technology, Malaysia
An example is in a brave venture in India where a 10 kW prototype floating solar generation facility is being developed for placement in a pond. Pilot projects of this nature have also started to take shape in countries like Japan, France and Australia.

Wind Energy in Oklahoma
09/15/14, Michael Teague, Secretary of Energy and Environment, State of Oklahoma
Oklahoma’s pro-business climate and excellent wind resource have helped to attract wind developers from across the country and the globe.

Geothermal resources used to produce renewable electricity in western states
09/15/14, Reprinted with permission from, Today in Energy
Geothermal plants are virtually emissions free, and unlike renewable sources such as wind and solar, they provide an available, dispatchable source of baseload power that is able to operate at a relatively high capacity factor.

Green growth: an operational tool (and GDP has had its day…)
09/15/14, Carlo Carraro, Director, International Center for Climate Governance
Natural capital, made up of several elements that nature provides us with as the sustenance and basis of our society (soil, raw materials, water, clean air, …) has an economic value: today any growth model that ignores this by now shared knowledge can no longer work.

Optimizing Solar Plant Implementation
09/15/14, Contributed by, Exosun
In this paper, we will focus on a theoretical study and its application to a concrete site. We will try to answer the question: How can we optimize the implementation of horizontal trackers on a solar plant?

Wind energy may help with grid stabilization

Submitted on: 09/19/14, 05:12 AM

A new study from the National Renewable Energy Laboratory suggests that wind energy could stabilize the energy grid of the eastern U.S. Grid stabilization is often an issue where renewable energy is concerned. At times, clean energy systems can generate more electrical power than an energy grid can handle. Frequency regulation plays a major role in grid stabilization in the U.S., and wind turbines may be a new solution to the stabilization problem.

Frequency regulation is the process through which the operators of an energy grid police the frequency of the infrastructure’s alternating current. Energy grids are strictly controlled throughout the U.S. and  are mean to put out electric currents with frequencies of 60 Hertz. In order to maintain this frequency, grid operators regularly change how much electricity is being funneled into the grid. Destabilization occurs when frequency is not properly regulated.
 
Wind turbines could be a new solution to this problem. According to the study from the National Renewable Energy Laboratory, wind turbines could be controlled to affect grid stabilization. The study shows that wind turbines can be tweaked using simple, commercially available mechanical parts. By changing the way these turbines generate electrical power, grid operators may be able to effectively control how much energy is coming into the grid.

UC makes largest solar-energy purchase by U.S. higher education institution
Submitted on: 09/10/14, 05:17 AM
The University of California announced Monday that it signed two power-purchase agreements that, combined, will provide 206,000 megawatt hours of solar energy per year — the largest solar energy purchase by any higher education institution in the U.S.
