why dont greenhouse gases absorb solar energy as it comes from the sun rather than after?

it reaches the earth's surface?

So far, no one has provided the correct explaination, makes you wonder how much the so called experts here really know. As with all things, it is not as simple as you might think.

The sun emits energy in many ways, but much of what reaches the earth is electromagnetic radiation in the visible spectrum, that is, light. The Earth's atmosphere, including green house gases such as CO2, H2O and NO2, is essentially transparent to visible light and thus, it passes through the atmosphere with little loss and reaches the planetary surface. At the surface, some of the visible light is absorbed, if it wasn't, the Earth would look like a shiney mirror ball, the enegy in this absorbed light is converted to heat (i.e. when the light is absorbed, the molecules of the surface begin to move more rapidly. Some of this energy is then reradiated from the surface as electromagnetic radiation in the infared spectrum (you can't see this, but you can feel it as heat radiating from a hot surface). So called green house gases are not transparent to infared radiation, and thus absorb it, much as the surface absorbs visible light. This heats these gases up.

Major Greenhouse Emitters and Solar Energy

Solar Greenhouse (Technical) $66.91 High Quality Content by WIKIPEDIA articles A greenhouse (also called a glasshouse) is a building where plants are grown. A greenhouse is a structure with a glass or plastic roof and frequently glass or plastic walls; it heats up because incoming solar radiation from the sun warms plants, soil, and other things inside the building faster than heat can escape the structure. Air warmed by the heat from hot interior surfaces is retained in the building by the roof and wall. These structures range in size from small sheds to very large buildings.

Solar Thermal Energy $90.81 High Quality Content by WIKIPEDIA articles Solar thermal energy (STE) is a technology for harnessing solar energy for thermal energy (heat). Solar thermal collectors are defined by the USA Energy Information Administration as low, medium, or hightemperature collectors. Low temperature collectors are flat plates generally used to heat swimming pools. Mediumtemperature collectors are also usually flat plates but are used for creating hot water for residential and commercial use. High temperature collectors concentrate sunlight using mirrors or lenses and are generally used for electric power production. Author: Surhone, Lambert M./ Timpledon, Miriam T./ Marseken, Susan F.

The European Solar Energy Market $114.71 Solar energy holds the highest potential among renewable energy sources and is thus a vital driver for a future shift in the primary energy mix. So far little research has been done which takes into account a truly interdisciplinary approach. The paper outlines the political and legal framework for the European solar energy market and analyses the implications for the linkage between environmental and social sustainability and profitability. Market analyses show the effect of certain policies, room for improvement as well as chances and risks from the exporters point of view. They identify administrative hurdles which should be eliminated and show as well that feedin tariffs are much more effective than direct investment subsidies. The argument for taking into account external costs is derived from life cycle analyses showing the high degree of sustainability as well as profitability for the society as a whole. Exporters will find a very promising and dynamic and therefore volatile market in some European as well as overseas countries.

Deployment of Solar Power to Energy Grids $90.81 High Quality Content by WIKIPEDIA articles Deployment of solar power to energy grids depends largely upon local conditions and requirements. Many industrialized nations are installing significant solar power capacity in their grids as a reliable economic supplement or alternative to other power sources. Long distance transmission allows remote renewable energy resources to be used to displace fossil fuel consumption. Solar, hydro and wind sources cant be moved closer to high population cities, and solar costs are lowest in remote areas where local power needs are the least. Connection costs alone can determine whether any particular renewable alternative is economically sensible. Costs can be prohibitive for transmission lines.
