Variability exists amongst reported levelized costs of energy (LCOEs) for wind. Wind is unique from traditional energy sources in that the fuel is free, with the majority of costs determined by capital expenses. Power purchase agreements (PPAs) are critical to the success of a project, offering a guarantee of long-term revenue. Integral to negotiating a PPA is having an accurate estimate of the LCOE...
Wind energy utilities use wind speed modeling and prediction to forecast their power production in order to participate in electricity markets. Time-series models which are indirectly based on a Weibull Distribution (WD) are used extensively to predict wind speed. The WD is converted into an approximately Gaussian distribution, as there are no rigorously developed time-series models for random variables...
The potential of distributive technologies in meeting future energy demand and reducing greenhouse gas emissions are enormous. However, improvements in efficiency and a reduction in capital cost are essential for them to be competitive against conventional energy sources. Natural gas microturbines are an example of distributive technologies that are growing in popularity among commercial and industrial...
