Greenhouse effects

In the past few decades and up to now, the fossil energy has exerted tremendous impacts on human environments and gives rise to greenhouse effects while the wind power, especially in offshore region, is an attractive renewable energy resource.

Geothermal energy constitutes an important renewable resource in Turkey that has been extensively utilized for heating buildings, power generation, greenhouse farming and various other industries. One of the most remarkable geothermal locations in Turkey is the low-enthalpy area of Afyon, where five main low-temperature (30–110℃) geothermal fields are exploited. However, further exploration drilling sites have proven inconclusive, casting doubts on the effective presence of high-temperature geothermal systems in the region.

Preservation of fruits, vegetables, and food are essential for keeping them for a long time without further deterioration in the quality of the product. Solar drying has been used since time immemorial to dry plants, seeds, fruits, meat, fish, wood, and other agricultural, forest products. The aim of the dryer is mainly for the welfare of the marginalized and poor farmers those who can’t afford hi-tech facilities and equipment’s to preserve their agricultural products. Drying of Safed Musli (Chlorophypum boribilianum) in open sun drying require more time and affected its quality.

An efficient lighting system (Compact 3U) was successfully applied to the micropropagation of gloxinia and potato plants. To compare the in vitro growth of plantlets under Neon and Compact 3U lighting systems, gloxinia and potato shoots were cultured on suitable media at different light intensities: (1) 45 µmol m-2s -1 (under Neon lighting system as a control); (2) 45 µmol m-2s -1, (3) 60 µmol m-2s -1, and (4) 75 µmol m-2s -1 (under Compact 3U lighting systems).

Definition “The earth is a natural greenhouse and is kept warm by water vapors, carbon dioxide (CO2), and other gases in the atmosphere, which absorb the sun’s energy and radiate it back toward the earth. This type of warming is called ‘natural greenhouse effect’. ‘Enhanced greenhouse effect’, on the other hand, causes global warming due to excessive levels of CO2 in the atmosphere.” Facts Average temperatures have climbed 1.4 degrees Fahrenheit (0.8 degree Celsius) around the world since 1880, much of this in recent decades, according to NASA's Goddard Institute for Space Studies.
