Alternative energy strategies such as photovoltaic panels can be used to teach about electricity and how it is produced.
Once photovoltaic cells and other means of producing energy become cheap the release of CO2 into the atmosphere will become optional.
With a photovoltaic system, the facility generates much of its own electricity and is able to resell some of it.
As the technology behind photovoltaic energy advances, consumers will be unable to resist the urge to convert.
Another method of on-site power generation is the photovoltaic cell.
