States were down 2.8%, thebiggest annual drop since the 1980s [1]. The Smart Grid enables grid operators to see further into thesystem and allows them the flexibility to better manage the intermittency of RES. This in turn surmountsa significant barrier, enabling wind and solar to be deployed rapidly – and in larger percentages to havea green Smart Grid.Going Green through the use of RES and make the planet sustainable and by so doing improve the airquality and environment. US government has required that by the year 2030 that 20% of the electricalenergy generated in the U S will be from RES. There are many different types of RES such ashydroelectric, biomass, wind, solar, wave, tidal and geothermal. The key to the usage of renewableresources is

Introduction K-12 classrooms typically focus on developing student’s math, reading, and writingskills, while subjects such as engineering are neglected. Without basic knowledge of engineeringand design concepts, high school graduates are less likely to pursue careers in technical fields.Furthermore, many students lose interest in math because

From the university standpoint, it was widely agreed that environmental issues, fromclimate change to land and water usage, to alternative energy, represent critical challenges forsociety [1]. Thus, NIU Institute for the Study of the Environment, Sustainability, and Energy –the ESE Institute – was developed. In addition, the University administration made fundingavailable for development, hiring faculty members and supporting students.

Given this background, typical need for Colonia homes is estimatedin the range of 400 KWh or lower per month. If a wind turbine can be designed to meet thisenergy need, monthly saving can be on the order of $60 for the home owner. Given their limitedincome, this is a sizable saving for the family.Figure 1 shows the typical wind speed6.7 in Mercedes, Texas, over a year period.
