A short exposure to far infrared light increased the space between nodes when the exposure occurred at the end of an eight-hour light period. Exposing the plant to ordinary red light reversed this effect. A combination of far red and red light produced the longest internodes. Plants grown in light that is too red may seem spindly and long-stemmed.

The sun is a source of light and energy for plants. They take energy from the light of the sun, carbon dioxide from the air, and water to make glucose, which is a sugar that plants store for energy. Plants are also filled with vitamin D, an important nutrient for animals, as a result of the sunlight they absorb.

Mar 05, 2013· Concentrating solar thermal plants (CSP), like all thermal electric plants, require water for cooling. Water use depends on the plant design, plant location, and the type of cooling system. CSP plants that use wet-recirculating technology with cooling towers withdraw between 600 and 650 gallons of water per megawatt-hour of electricity produced.

Artificial light is composed of visible light as well as some ultraviolet (UV) and infrared (IR) radiations, and there is a concern that the emission levels of some lamps could be harmful for the skin and the eyes. Both natural and artificial light can also disrupt the human body clock and the hormonal system, and this can cause health problems.

In greenhouses, plants receive the wide solar spectrum and so the color of light provided by supplemental lighting has much less impact on extension growth. As discussed in previous articles, the amount of red light relative to the amount of far-red radiation (R:FR) also has a pronounced effect on leaf expansion and stem elongation.

Jul 13, 2012· Solar radiant energy as visible light acts as a fuel source for green plants. Through photosynthesis, plants use visible light to change carbon dioxide and water into simplified sugars and starches which they use for nutrition. Though this light is important, a green plant does not use all light available for its growth.

Concomitantly, the amounts of solar UV-B radiation reaching the Earth's surface is increasing. UV-B radiation has been shown to be harmful to living organisms, damaging DNA, proteins, lipids and membranes. Plants, which use sunlight for photosynthesis and are unable to avoid exposure to enhanced levels of UV-B radiation, are at risk.
