Sustainable agriculture is farming in sustainable ways (meeting society's food and textile needs in the present without compromising the ability of future generations to meet their own needs) based on an understanding of ecosystem services, the study of relationships between organisms and their environment.
The integration of two technologies, vertical farming with sustainable practices, will be one of the main ways to grow in population without further degrading our lands.
Vertical farming is being used to help bolster local food supplies and provide fresh produce to communities in large cities. Many of these farms are vertical farms and can produce much more crops in a small area than can be produced in outdoor, soil-based farms. However, not all indoor farms are built on such a large scale. Some indoor farms can be created in an area as small as a basement and used by a single gardener to provide fresh produce for their home.
Most indoor farming uses a combination of hydroponics and artificial lighting to provide plants with the nutrients and light they would only receive when grown outdoors.
Solar and wind energy are both applicable sustainable practices for indoor gardening.
Solar panels converts the sun's light in to usable solar energy using N-type and P-type semiconductor material. When sunlight is absorbed by these materials, the solar energy knocks electrons loose from their atoms, allowing the electrons to flow through the material to produce electricity. This process of converting light (photons) to electricity (voltage) is called the photovoltaic (PV) effect. Currently solar panels convert most of the visible light spectrum and about half of the ultraviolet and infrared light spectrum to usable solar energy.
The terms "wind energy" and "wind power" both describe the process by which the wind is used to generate mechanical power or electricity. ... This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity.
