Investing in green technology

The emissions of carbon dioxide increase and, unfortunately, will dramatically change the climate of the planet over the next 50 years.
O Lord Rees President of the British Royal Society, said it was important for governments to prepare for the worst impacts of climate change. "Even if you do not verify this scenario, we should prepare ourselves properly," he said.
In his speech on the 35th anniversary of the Royal Society, Lord Rees said that that part of the preparation is to invest in green technologies and their development while it is imperative to save the planet, reaching a binding agreement to combat climate change.
"The international community should take effective measures to reduce emissions of carbon dioxide in the UN Conference on Climate in Cancun, Mexico, while Rees said that" The solar energy gives a lot of medium and long term benefits, but we need direct replacement of nuclear power. "
He noted finally that the British government spends 600 million pounds per year for research in energy, while the health sector the amount is 1.4 billion

Solar mirrors in space to save earth

Dr Rajendra Pachauri heads the Intergovernmental Panel on Climate (IPCC), told the meeting in Cancun said "should be to stop the rise in average global temperature will have to look at geoengineering, says publication of the Telegraph.
Margins are narrow and should provide solutions to combat this phenomenon.
Global warming is most visible and should take more drastic measures to reduce greenhouse gas emissions.
The Dr Rajendra Pachauri, said that scientists are considering installation of solar mirrors in space to reflect sunlight.
Besides, considering the spray of the sea surface in quantities of iron, in order to create suitable conditions for growth of plankton to absorb carbon dioxide from the atmosphere.
At the Cancun meeting of representatives from over 190 countries and conducted in the hotel Moon Palace.
The purpose of the meeting is to reach a binding agreement to reduce greenhouse gas emissions.
The Dr Pachauri pointed out that if you continue to increase greenhouse gas emissions, the consequences will be disastrous for humans, nature and the world at large.
Climate change is a fact and requires global effort to avoid catastrophic consequences for the planet.

Google Earth Engine protects forests

 Google Inc. presented at the meeting of the UN Climate in Cancun, a new technology for the protection of tropical forests.
This technology will be an important tool for governments and will further strengthen relations and trust between rich and poor nations.
According to a report in Reuters, the scientists via satellite platform can monitor real-time changes occurring in tropical forests.
The platform Google Earth Engine forests collect images from satellites to get the U.S. and France and stored in open database sharing.
So the scientists via computer can monitor and record changes that occur in forests.
It is an important weapon for the protection of forests, Google Earth Engine.
Noted that deforestation accounts for 17% of carbon dioxide resulting from human activities.
The UN Summit on Climate in Cancun began on November 29 and ending on December 10.
The Conference is not in the spotlight, as most predict that participants will not be able to reach, rather than a binding agreement, nor even the adoption of some smaller sub-agreements on climate (eg the agreement on protection of areas of deforestation), as quarrels and interests as they appeared clearly in Copenhagen, remain at the forefront.

2010 was the warmest year worldwide since 1880

Scientists reported officially that all around the world. Temperatures have risen by some dangerous areas almost non-viable.
A typical example of Pakistan in May when the mercury climbed to 53.3 degrees Celsius!

According to published today in the German newspaper Tagesspiegel, which relies more responsible for the reinsurance company in the world, the German Munich RE, 2010, was the warmest year worldwide since 1880 (regardless of whether Europe today and our country, woke up with snow ...).

Characteristic is also that in Los Angeles and Moscow reported record temperatures in summer 45 and 37.8 degrees respectively, according to Peter Chepe, head of research department for environmental hazards.

Reduce the amount of plastic on our everyday use

The plastic trash accumulating in the oceans are "death traps" for millions of birds and marine organisms that live and feed on them.
Below we cite a few ways to do this:
- reduce the use of plastic bags.
-Use cloth bags for shopping.
-Avoid buying soft drinks in plastic bottles, choose glass, if any.
-Take a thermal mug for coffee and ask the stores where you buy coffee on the way you fill it up instead of disposable cups.
-Do not buy food in plastic packaging, prefer in bulk.
-Make your own bread or buy it from bakeries to wrap it in paper.
-To clean up use baking soda and vinegar instead of chemical cleaners in plastic bottles.
Buy-in washing powder cartons, not plastic.
-Choose Milk packed in cardboard or glass container.
-The remains of food do not wrap in plastic wrap, aluminum foil prefer.
-Use matches instead of plastic lighters.
Buy-fabric toys for your pets.
-Pack your stuff in the newspapers instead of the familiar plastic cover with bubbles.

Enviroment needs help

The reckless destruction of natural areas in which and by which we live, has advanced in recent years at a rate dangerous. At the same time and place alongside it and the direct or indirect destruction of monuments of culture of centuries has bequeathed to our country. Companies and individuals trying to declarations and theoretical analysis is convincing, what? - For immediate need and an obligation we have to respect and preserve the "natural environment" and our historical monuments.

The intention is undeniably good and commendable, but I fear that is likely to run into figures of speech, though not explored the causes of evil and not reversed by the root.that in many cases, the seizures begin their journey towards a theoretical pursuits aesthetic form . Many believe that what is needed is to enlighten people about the value of space and environment. Sometime in the arsenal of the Enlightenment found no statistical evidence for biological and other effects that can cause change or disaster occurs, is all right.

Photovoltaic Systems

Photovoltaic systems are devices utilizing solar radiation, producing electromotive force (ie, become electrical generators). A photovoltaic system consists basically of photovoltaic panels, configuration management and control and of course the necessary cabling and transmission coupling. Photovoltaic systems can be grid or grid, depending on whether or not coupled with the national electricity grid. In the case of the photovoltaic system, is usually necessary and the availability of means of energy storage (batteries) to power availability during non-sunlight (night, cloudy days).

The development of photovoltaic systems is initially placed in the middle of last century (1950) arose when service needs of applications of space technology, while after 1970 the first steps in place for the use of PV in more everyday applications, something that helped and oil crises 1973 and 1979. Nowadays (2009), the Photovoltaic Technology has managed to produce several PV systems affordable for even small investors, which in combination with social sensitivity and the shift to renewable energy sources, making fruitful the rapid proliferation of applications of PV with a direct impact on micro-and macroeconomics, management of natural resources and our environmental performance.

Solar Energy is free for ever

The term solar energy we mean all forms of energy emanating from the sun. The most common form of solar energy is the Light and Heat. But there are lesser-known forms, including the general description of electromagnetic energy.
The sun as an energy source is inexhaustible and therefore limitless is the energy that comes from him. Also, solar energy as a physical act is classified as a Renewable Energy in the sense that it is destructive to the earth's surface as long as these natural processes operating in Earth's atmosphere and propitiate the Solar Radiation and still function perfectly well apart from any physical or human impact.
In addition, the Solar Energy is jointly-owned and-shared in the human population since the flow to each of us is indiscriminate, unhandled and above is FREE.

Green energy from straw



Have you heard of biobutanol? Is one of the "new generation biofuels, but ... who comes from the past, as until the mid 20th century a number of countries producing the environmentally friendly fuel in small quantities. Today, 60 years after the production and use of biobutanol (butanol produced from biomass) and again employing experts and companies, and even some of them argue that the fuel not only has nothing to envy from ethanol, but also superior in connection therewith.
One is a chemical engineer at the Agricultural Research Service U.S. Nazimp Kouresi. As he says, biobutanol offers several advantages, as it can be transported through the existing distribution network, so no additional investment, can be produced in facilities that produce ethanol.
Furthermore, it has greater resistance to water contamination in gasoline blends can be used comfortably in internal combustion engines. Also worth noting that according to the results of a study of companies BP and Dupont a mixture of butanol (16%) and gasoline behaves like E10 (ie, a mixture of ethanol 10% and 90% gasoline).
Fewer processing steps
The Kouresi since 2003 had begun to study the production of biobutanol from wheat straw. The method is based, like other bacteria, the use (of the species Clostridium) in the process of fermentation, but the following three instead of four stages of processing and produces additional quantities of biobutanol fold compared with the traditional method, as shown by initial tests . Then, after improvement of the Kouresi and co-produced by 430 grams sugar 192 grams of acetone, biobutanol and ethanol. This means that if mazikopoiithei the process can produce 375 liters of these chemicals per ton of straw.
H biobutanol, though belonging to biofuels "new generation" is not something new in the world of energy. For example, during WWII the U.S., Britain, the Soviet Union and India have produced the fuel for their energy needs, but without follow-up due to increased production (cheap) oil covered the demand in the postwar era.
As for the Agricultural Research Service (ARS), which employs Mr. Kouresi, this is the main scientific research agency of the U.S. Department of Agriculture, which runs 1,200 research projects in 22 key national projects, employs 2,100 scientists and other 6,000 employees and the budget for 2007 was 1.1 billion dollars. (So, to get a taste of expenditure and personnel working outside the vital area of research).
The chemical engineer at the Agricultural Research Service U.S. Nazimp Kouresi adds enzymes into a bioreactor for the simultaneous hydrolysis of wheat straw into simple sugar and the production of butanol.

fear of destroying our world

The fear of destroying the world as we know it today, from environmental pollution has led humanity to a natural shift to clean-energy sources. The natural energy resources can be a clean driving force of the new millennium.

Many years ago since the ancient Greeks worshiped the sun, they made sacrifices to the god of the seas, Poseidon, and trembled at the thought that Aeolus will open the bag to let out the furious winds. Out of fear or appreciation for the "services" offered by the elements, our ancestors showed their gratitude in every way. Centuries later, things changed. The charcoal and the "black gold" have replaced the ancient anthropomorphic deities and become the new driving force in the world. When the 70 was the first oil crisis the leaders of the world felt the earth "leaves" under their feet. "The oil will eventually end, it becomes more expensive, let alone destroying the environment" seems to be thought and turned back to "mother nature" who gives generously, more cheaply and its energy in a world slowly dying from the effects of contamination environmental and climatic changes. New global energy 'gods' is the sun, wind, water, including biofuels and hydrogen newcomer. All countries of the world make a race to incorporate Renewable Energy's energy potential. In route Greece, although not considered a privileged place, away from the monitor world events and trying to gain ground reminiscing the glorious 'ancient' past. Until 1920, our country has been energy self-sufficiency based on biomass and wood. He managed after years, in 1980, although not an oil producer to depend on 73% of it. Today the rate of dependence on fossil fuels has reached 95%. The National Observatory calculates that if the 'home' emission of dangerous gases in the environment increased by 39.2% in 2010 (the EU has put us than 25%), this creates an excess of approximately 15,000,000 tonnes of carbon dioxide. The fine will pay for our environmental violation shall be a 140 to 450 for each Greek household per year, based on estimates of Greenpeace. From 1990 to 2004 we increased the "national" broadcast by 26.6%, "conquering" the Fourth World status, along with Canada, the black list of countries contaminants. They do not need more reasons to support the need to change energy course. Renewable energy has become the first target. Green Energy
Hydropower Large hydropower plants are not renewable energy projects because they interfere with the natural environment. In recent years growing rapidly, the technique of small hydro power up to 10MW. They have limited impact on the environment and settle in small streams. In Greece, we have a large number of usable seats for the construction and operation of small hydropower projects. Ideal points are the water districts of Epirus, Western Greece, Western Macedonia, Eastern Macedonia and Thrace, and western and northern Peloponnese. These areas can be estimated to provide up to 4363 MW of energy. The goal is 2010 the installed capacity of small hydropower projects to reach 364 MW by approximately 60 MW available in the country today. On the other hand, hydrogen has employed many Greeks in terms of its use as an energy source. Recently managed to use an appropriately modified burners, boilers and internal combustion engines in their homes to generate electricity and heat, and in moving cars. Six months ago, about the program announced HYDROSOL, for which researchers at the Laboratory of Aerosol and Particle Technology at the National Center for Research and Technological Development of Chemical Processes, Institute of Thessaloniki, were honored with this year's Descartes Prize for research use of hydrogen as an energy source by building the first solar hydrogen reactor. Plans for researchers is to install 1 GW unit soon to rise to 5 GW.
Solar Energy The Life-Giver sun is the guest of honor in Greece more than 300 days a year, the warm rays of the country, while there are areas that are lit more than 3,000 hours per year. This may not do so good for sunbathing, but if these light strips make electricity, they can provide 4500 kilowatt hours per square meter, or about as much electricity consumed by the average Greek annum (4.000 KW per capita in 1999). The conversion of solar energy into electricity either directly by photovoltaic systems or using the heat from the sun's rays to heat a fluid and produce steam that feeds a turbine or a generator. The national investment in the sun for solar water heaters sold out. Greece holds third place in the world, 350m2 solar heaters corresponding to 1,000 residents. In this way the country is spared the pollution would be from a conventional power plant, the capacity of 200 megawatts, which spends 1.1 billion kilowatt hours a year, according to data from Greenpeace. On the other hand, the EU believes that if you "dress" the appropriate buildings in the country with collectors since the Greek electricity generation will provide 30% of its power. In this way, our country might be able to confront claims in the "dark" Germany with the help of the sun reaches the production of 1.200 MW, while the "light" Greece just exceeding 5,5 MW approx. It is not surprising that until 12.31.2006 in RAE 2482 tabled projects for the production of 32.019 MW of renewable energy, ie three times the total domestic installed capacity of electricity. Now that Law 3468/2006 subsidizing 0.40 to 0.50 euro each kWh produced by the sun and fed into the electricity network, appears to be motivated to surpass the target of 3.000KW, ie 20% of installed RES. The Solar Energy Industries Association is proposing the installation of ten million square meters panels (two and a half times the area of Attica, that is) until 2015, which corresponds to a square meter for every Greek and Greek. Greek banks have established financial products targeted at those who want to invest in photovoltaic systems, either for domestic use or as a business.
