Why Do Wind Turbines Have Three Blades?

The commercial wind industry has maintained an unusually high degree of standardization in turbine technology for going on 25 years. Wind energy experts usually attribute this convergence to the technical superiority of the now standard 3-blade upwind design, often referred to as the “Danish concept,” or to a grassroots, “bottom up” development path that allowed Danish manufacturers to build the world's most reliable turbines in the 1980s. This new history of the modern wind industry, which focuses on the evolution of turbine design after 1970, challenges both of these explanations.

Short-Term Power System Load Modelling Using Artificial Neural Systems

Power systems are very dynamic in nature, and it is important for power systems to be simulated and modeled accurately for optimal performance of the system. Historically, load modeling coupled with forecasting has always been important for power system operation.  In current times with the onset of the deregulation of the energy industries, load modeling and forecasting have become even more important.

Offshore Wind Development in The Bahamas: Challenges and Benefits

Energy production and distribution can present many hurdles for small-island developing states.  The high costs associated with electricity generation, antiquated production facilities, and unreliable distribution grids can all erode the potential for economic growth and sustainable development.  This rings very true for the Commonwealth of The Bahamas – a 470,000 km2 archipelago of islands in North

Remote Sensing of Ocean Winds

Surface winds over the world's oceans are routinely monitored by
low-Earth-orbiting satellites.  The satellite instruments used are
either scatterometers, which are radars that measure the echo from the
surface, or radiometers, which measure the microwave radiation (i.e. heat)
emitted by the surface.  This talk will provide an overview of these
technologies, as well as describe ongoing work by the Microwave Remote
Sensing Laboratory to study wind signatures in hurricanes and
high-latitude winter storms from aircraft. 

 

Dividing Up the Pie: Biological and Fisheries Challenges in Coastal Marine Spatial Planning

Coastal Marine Spatial Planning (CMSP) requires the ocean be divided into units, and that multiple stakeholders provide input towards this end. Spatial ecology of single and multiple species can help guide biological division of ecosystems; however these decisions require the assumption of a closed system despite the knowledge that all ecosystems are open to varying degrees. Examples will be given that illustrate these challenges from ongoing work.
