Types of Green Energy

  

Today we live in a world where energy needs of human are growing on a daily basis and the fact is that they will grow more and more. Specifically we have created a situation where we have to seriously think about how to get into power (energy), but to take care  that it does not reflect negatively on the environment. Here we are talking to a number of environmental disasters such as oil spills, acid rain and of course radioactive radiation.
 Probably most of us are not aware of what measure all of these threats to the environment are actually threatened. According to the latest research it has proven that the release of greenhouse gases is the main factor  for global warming on which more and more is talking everywhere on the globe. So we are aware that we need more and more  energy , however, we have to consider alternative sources that do not pose a threat to the environment.
 When we talk about energy sources, there are fossil fuels that certainly have the greatest negative impact on the environment. With combustion these fuels emit large amounts of carbon in the atmosphere. Bio energy unlike fossil fuels, does not constitute such a threat, because with their production comes to  the closing of the carbon cycle.

 Solar energy facts speaks that our Sun could be the main source of energy for humanity in years to come.
 Hydro power is another source that it is taking advantage of not producing adverse effects on the water. The problem with this energy source is that many newly constructed facilities such as dams may well affect the environment. Changes may result in a change of the local bio-system.
 From all these sources there is gentlest looking at wind energy, which actually has a zero negative impact on the environment but there is a fear that windmills can hurt  the birds, and the assumption of the frequencies that they produce in humans can cause anxiety and headaches.

 There is also nuclear and geothermal energy. Nuclear energy is considered the cleanest energy production. The biggest problems are seen in fact that used fuel must be stored for hundreds of years underground and of course fear of mail function that can be devastating for people and nature. Geothermal does not lead to environmental pollution, it should only build the necessary infrastructure, but when you take into account the impact of these objects, we notice that is indeed negligible.

   Solar Thermal Energy

 It is known as a technology to convert solar energy into heat energy. Solar energy collectors are divided into low temperature, medium temperature and high-temperature collectors.

 If you've ever noticed the flat panels on houses, they are low-temperature collectors who are designed for water heating and air conditioning. They are mostly installed for pool heating and water in homes, but can also be used for cooling and ventilation.
 Heat transfer medium here is water or air. Flat-plate collectors are the most common type of collector that can be seen at various facilities.
 Heat water for residential or commercial use can be carried out using a collector with a cover or medium temperature collectors. They are also used for disinfection, desalination and cooking.
 If you did not know solar energy can be used for cooking, pasteurization and drying. Collectors that are used to prepare food at the same time reduce the demand for fuel and timber, and improve the quality of living.

 Only developing countries for some time have presented a modern system, which applies to solar water disinfection. It is one of the simpler methods and cheaper method, which relies on solar radiation.
 High temperature collectors focus on solar radiation while using mirrors or lenses to produce electricity during which improve quality of life by reducing the amount of smoke that would otherwise be created.
 In solar thermal power plants solar radiation is concentrated by the lens to achieve a higher temperature. This technique is referred to as concentrated solar energy.

 Despite the high degree of reliability and free source of energy the only obstacle to the entire project is the price of lenses and mirrors that must cover large areas, in order to obtain larger amounts of energy.
