At conclusion of constructions, have pupils refer back to design briefs and self evaluate in terms of the performance of their design. Through discussion and research, bring out the idea that wind has many benefits for human beings. Have each group research this and turn into an illustrated chart and display. In 1993, ECNZ erected the experimental Wind Turbine near Brooklyn in Wellington. Its maximum output of 225 Kilowatts is enough to produce enough electric power for about 6080 average homes.
Wind energy is expensive at present when compared to existing sources.
This is expected to change as the technology improves and other options, particularly fossil fuel becomes more expensive or environmentally unacceptable. The 225 kilowatt Wellington wind turbine generated one million kilowatt hours of electricity in its first year. Express as a percentage. Have pupils suggest the best site locally for wind power generation. Define visual impact.
