The burning of fossil fuels is the main source of the excess greenhouse gases causing climate change, but there are other sources to consider as well.A special report from the Intergovernmental Panel on Climate Change (IPCC) estimated that, in the last 150 years, fossil fuels and cement production have been responsible for only about two-thirds of climate change while the other third has been ...
Hydroponics research mimicking a Martian environment uses LED lighting to grow in a different color spectrum with much less heat. Ray Wheeler , a plant physiologist at Kennedy Space Center's Space Life Science Lab, believes that hydroponics will create advances within space travel, as a bioregenerative life support system .
Aeroponics is the process of cultivating plants in an air or mist environment, eliminating the need for soil or an aggregate medium. The term "aeroponic" originates from the ancient Greek: aer (air) and ponos (labor, hardship, or toil).
The notion of a greenhouse conjures up visions of everything from something barely larger than a terrarium to an expansive conservatory, like one found in the gardens of Biltmore Estate.

Thermal lights at a greenhouse in Närpes, Finland. Heating or electricity is one of the most considerable costs in the operation of greenhouses across the globe, especially in colder climates. The main problem with heating a greenhouse as opposed to a building that has solid opaque walls is the amount of heat lost through the greenhouse ...
Lettuce grown in indoor vertical farming system. Vertical farming is the practice of growing crops in vertically and horizontally stacked layers. [1] It often incorporates controlled-environment agriculture, which aims to optimize plant growth, and soilless farming techniques such as hydroponics, aquaponics, and aeroponics. [1]
The distillation process requires significant energy input to generate heat. Heat is sometimes generated with unsustainable natural gas fossil fuel, but cellulosic biomass such as bagasse is the most common fuel in Brazil, while pellets, wood chips and also waste heat are more common in Europe.
