These goals have been defined by a variety of disciplines and may be looked at from the vantage point of the farmer and the consumer. Sustainable agriculture refers to agricultural production that can be maintained without harming the environment or the health and well being of the farmers and consumers.

Solar powered electrical generation relies on heat engines and photovoltaics. Solar energy's uses are limited only by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation anddisinfection, daylighting, solar hot water, solar cooking, and high temperature process heat for industrial purposes.To harvest the solar energy, the most common way is to use solar panels.
