A.PANEL SOLAR solar panel is a device consisting of solar cells that convert light into electricity. They are called solar above the Sun or "sol" for sun is the strongest light source that can be utilized. Solar panels placed on the roof of the house can be put solar panels on the roof of the house and in the yard. The solar panels are also commonly found on remote islands to be used as a source sassafras of energy because the sun light or heat source. Solar Panels sassafras in remote island areas Number of servings use of solar panels in the world is very small electrical pemroduksian, restrained by the high cost per watt compared to fossil sassafras fuels - can be higher tenfold, depending on the circumstances. How Solar Panels sassafras work on a house now cost solar electricity panels makes it impractical for everyday use where electric power "cable" has been available. When energy costs rise in a certain period, or when a breach occurs that reduces sassafras the production cost of the production of solar panels, this is unlikely to happen in the near future. B.GAS GREENHOUSE
Greenhouse sassafras gas or in English is called green house effect / global warming gases that are present in the atmosphere which causes the greenhouse effect. These gases actually occurs sassafras naturally sassafras in the environment, but can also arise as a result of human activity. Scheme Greenhouse Gas Effect (Green House Effect / Global Warming)
Greenhouse gases are the most widely-shaped water vapor that reaches the atmosphere by evaporation of water from the sea, lakes and rivers. Carbon dioxide is the second largest gas derived from natural processes such as volcanic eruptions; breathing animals and humans sassafras (who inhale oxygen and exhale carbon dioxide); and combustion of organic materials (such as plants). Carbon dioxide can be reduced due to absorption by the oceans and absorbed by plants for use in photosynthesis. Photosynthesis break down carbon dioxide and releases oxygen into the atmosphere and take a carbon atom. Water 1.Uap
Water vapor is a greenhouse gas that is naturally occurring sassafras and is responsible for most of the greenhouse effect. In climate models, atmospheric temperature increases caused by the greenhouse effect due to anthropogenic gases will lead to increased water vapor content in the troposphere, with a rather constant relative humidity. Increasing the concentration of water vapor resulted in an increased greenhouse effect; which resulted in the increase of temperature; and again increase the amount of water vapor in the atmosphere. This situation continues until it reaches a sustainable equilibrium point (equilibrium).
Humans have increased the amount of carbon dioxide sassafras released into the atmosphere when they burn fossil sassafras fuels, solid waste, and wood to warm buildings, moving vehicles and generate electricity. At the same time, the number of trees that could absorb carbon dioxide dwindling due to encroachment for timber or for the expansion sassafras of agricultural land.
Although the oceans and other natural processes capable of reducing carbon dioxide in the atmosphere, human activities that release carbon dioxide into the air much faster than nature's ability to reduce them.
Methane is the main component of natural gas also includes greenhouse gases. He is an effective insulator, able to capture 20 times more heat than carbon dioxide. sassafras Methane is released during the production and transport of coal, natural gas, and petroleum. Methane is also produced from the decay of organic waste in landfills (landfills), it can even remove sassafras it by certain animals, especially cows, as a by-product of digestion.
Nitrogen oxide is a gas that is very strong heat insulator. He produced mainly from fossil sassafras fuel combustion and agricultural fields. Ntrogen oxide can capture heat 300 times greater than carbon sassafras dioxide.
Other greenhouse gases are produced from manufacturing processes. Berflourinasi mixture produced from aluminum smelting. Hydrofluorocarbons (HCFC-22) are formed during the manufacturing of various products, including foam for insulation, furniture (furniture), and a seat in the vehicle. Refrigerators in some developing countries sassafras still use chlorofluorocarbons (CFCs) as the cooling medium in addition to be able to withstand the heat also reduces the atmospheric ozone layer (the layer that protects the Earth from ultraviolet radiation).
Greenhouse sassafras gas is a collection of gas in the atmosphere, which has the ability to absorb infrared sassafras radiation originating from terrestrial radiation, clouds, or from the atmosphere. Naturally, the presence of greenhouse gases is very important to maintain the temperature of the earth stays warm. However, if the concentration exceeds the normal limits, these gases can cause heating at the earth's surface sassafras berimb
