Alternative Energy ProgramsIntroductionEnvironmental issues, U.S. dependence on foreign oil and depleting fossil fuel reserves: all ofthese issues represent an increasing awareness of the need for energy efficiency and alternativeand renewable energy education. Almost half (49%) of all energy produced in the U.S. isconsumed by the building sector. This is almost the same amount of energy consumed by bothtransportation (28%) and industry (23%) combined. [1] According to the U.S. EnergyInformation Administration, fossil fuels supply 76% of the total building sector energyconsumption. To address the building sector, architect Edward Mazria, in 2002, establishedArchitecture 2030, a non-profit, non-partisan, and independent organization. Architecture

Rapidly growingeconomies of developing nations such as China, Brazil and India have significantlyincreased use of energy in these and other nations. In addition, increasing climate changeconcerns as a result of increasing use of fossil energy has made the public more aware ofthe issues and problems associated with energy usage. Figure 1 from Department ofEnergy1 clearly shows the increasing trend of energy use and projected increases inenergy use. It is interesting to note from Figure 1 that use of renewable energy resourceshas also increased with an increase in overall energy usage and more and more renewableenergy sources are expected to

Over the next 12 months, 50% of solar firms expect to add jobs. Thiswill increase the overall solar employment to 120,000 people, an annual growth rate of over25%. That is particularly significant for a troubled U.S. economy whose overall growth isexpected to be around 2% over that same time period.1 Although solar

As such,engineering professionals who work for both government agencies and private firms areresponsible for facilitating and participating in public meetings at some point during theircareer.

Spatial skills, and in particular the ability to rotateimages in one’s mind, are especially important for technical fields such as engineering (Maier,1994)2. Studies have shown that spatial visualization skills are a factor in the success ofengineering students. Gimmestad (1989)3 found that students’ spatial visualization skills were astronger predictor of success in an engineering design course than math ACT scores orexperience in a high school shop or drafting class.

Students “failing” the PSVT:R were encouraged to take the spatial training course asbefore. Over time, the student grapevine began endorsing the benefits of the course and graduallythe enrollment consisted of about 60-70% of those failing the PSVT:R. In 2004, a secondlongitudinal study found that students who “failed” the PSVT:R but took the course had highergrades, retention rates, and found it easier to learn solid modeling than students “failing” thePSVT:R but choosing not to take the spatial training course (Sorby18).
