At the Earthship house in Scotland, micro, or small and local, electricity generators are used to provide all power needs. Each generator is powered by a renewable source of energy, which doesn't deplete materials from the environment. The solar generator uses the sun's energy to generate 10% of the electricity needed. The wind turbine contributes 40%, and the remaining 50% is generated by the hydro turbine. One drawback is that the power output is reduced when there is no sun or wind.

This clip could be used to ask the students if they know anywhere micro-generation from renewable energy sources is used. Investigate how wind, hydro or solar energy could be used in their local community.
