Emerging engineers discover how important it is to conserve energy as fossil fuel supplies are being diminished. This is accomplished by working through a handout that explains energy requirements for heating a home during the winter. Learners calculate kilowatts of energy needed. They then consider the addition of insulation and the reduction of the thermostat setting for that same house and recalculate the energy needs. Completing a lesson like this will increase awareness and contribute to future decisions in terms of energy use.
