Kingdom faces many challenges to the use of solar energy

International expectations that the Kingdom is the largest source of solar energy in Almariyad - Fahad dissuaded

Said economist who specializes in the field of energy that, despite the global outlook that the Kingdom is the largest source of solar energy in the world may exceed revenues in the future oil revenues, but that the kingdom faced some challenges in the development of solar energy as fuel renewable and environment-friendly, including the availability of fossil fuels and its low cost compared to generate solar energy and the impact of dust on the solar cells that need great care and cleaned continuously, where the cells lose more than 25% of its capacity to soak up the sun next.






He pointed out that solar energy investments of long-term investments achieve returns that takes the multi-year, while the wishes of most investors prefer investments that generate profits in the short term and low-rate risks.






He told "Al-Riyadh" Dr. Fahd bin Juma Member of Association of Energy Economics International that there is a study carried out by two instances of the European Union in the energy production sector solar Saudi based around that the Kingdom will be the largest source of solar energy in the world and has revenues exceeding revenues of the oil that Saudi Arabia is the largest producer her, and he, too, pointing out that there is a tendency to support the establishment of European farms for the production of solar energy in Saudi Arabia in order to reduce greenhouse gas emissions such as carbon dioxide and other gases that cause global warming.






He said that the Kingdom of the countries most exposed to solar radiation, where the average units of light energy falling on the Kingdom of 2200 units (kWh per square meter) per year. He completed that, although by some authorities in the Kingdom of systems using photovoltaic cells in the application of high and medium ability learned from some of the ground after being proven, others are still under study, but that these uses represent only a fraction of the total production of electric power in the Kingdom shall not exceed the capacity of generating 2 megawatts PV compared with some of the world. He pointed out that solar power covers only 4% of the deserts in the world where there is sufficient solar panels to provide electricity to the world in spite of the existence of enormous potential, but they represent less than 2% of the world's supply of total energy in 2008.






He explained that the solar energy currently provides about 5% of the electric power installed at the global level, where the project is the Sahara is the largest project in the world of solar energy, which reached a cost of 555.3 billion dollars and is designed to convert sunlight falling on the vast desert to enough electricity to supply 15 % of energy demand in European countries. Abizaid and that 2008 the best year for global solar energy market, which was better than 2009 after PV production fell in the second half of the same year, despite what has been achieved gains of the total systems installed as a result of strong sales of German in the fourth quarter.






Ibn al-Fri that although the high fixtures annual PV in the world from 5.8 gigawatts in 2008 to 6.6 gigawatts in 2009, but that the market for PV reduced its market value by 15.8% to $ 17 billion due to the sharp decline in the prices of PV cells and their different kinds.






Ibn al-Gomaa said the Kingdom is facing some challenges in the development of solar energy as fuel renewable and environment-friendly, including the availability of fossil fuels and its low cost compared to the generation of solar energy and the impact of dust on the solar cells that require great care and cleaned on an ongoing basis, where you lose these cells over 25% their ability to soak up the sun next.






And went on that investment of solar energy from the long-term investments which can take to achieve returns in a number of years, while the wish of most investors in investments that generate profits in the short term and rate risks low, add to that solar energy is regular and this adds further costs to invest in them.






He stressed'm Friday in his closing remarks that the Saudi investments in the new field of atomic energy as an energy source after oil may not support the expansion of projects, solar power, although some research the current global and uses limited and try to use in the field of water desalination, citing that the opportunities of economic feasibility still exist at the moment of our oil energy enough for over 70 years, which may give us a great opportunity to take advantage of technological developments, solar with lower costs and we have only imported and installed, and this may also gives us enough time to invest our capital in other areas that the most appropriate

Competition on the «black diamond» up to end the killings in France!

Paris - Hassan Tlili:






In the midst of France celebrate Christmas and New Year's Day was a farmer in a village in the territory of «Drome» Indeed, the country's south-east fire a few days ago on another farmer was shot dead because it was believed that he entered his field structure of embezzling some beads black truffles from his ranch. Although the dead man's widow and two children believe that it was the culprit fire on the farm of the late, the majority of farmers in the region have expressed their sympathy with the murderer, who was arrested and jailed. This is due to the sympathy of the most important of several reasons that a kilo of black truffles French is currently sold in the markets of regions that grow between the 800 thousand euros. The price increase this to at least five times when the arrival of the French black truffle dishes or wealthy pedophiles by the middle of the case and some of the poor. Therefore also called the black truffle «urgent black« the buyer and sellers and consumers.

He says a number of area residents «Drome« The high price of French Truffles Black French in recent decades was at the same time a blessing and a curse. Many farmers are counting on black truffles for projects McCann able to accomplish without the proceeds of «black diamond». However, this revenue is similar to its impact on the hearts of the impact of drug proceeds owners. In other words, black truffles today contributes to the worsening escalation between farmers in the transfer of escalation, sometimes to a settling of accounts or the wars.






The fact that these wars and faces are many, including trade war between the producers Truffles Black French and Chinese counterparts who have become nearly two decades float the European markets, including the French market the type of Truffles Black China sold at prices lower than prices Truffles Black French but it offers customers as if the French production . And to try to win this war, researchers French and Italian in the past year to map the genes Truffles Black French and Italian even allow security officers to address the cheats by referring to this map. But evil tongues say that there was a secret agreement between the Italians and Chinese could be the Chinese from which to obtain this type of map, and germination of black truffles to respond to the specifications of French black truffles. While waiting for the French to get this information denies the agreement or whether Saddam Hussein, agricultural experts warned in recent years to increased risk of wars, particularly Truffles Black French truffles due to climate change that will influence the future drastically on a map of the places where truffles grow in the world.
