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

Biomass Energy

Biomass call on any new organic matter produced by plants as a result of the process of photosynthesis. Energy from biomass based plant and animal material such as wood from forests, residues from agricultural and forestry processes, and industrial, human or animal wastes. However, biomass is not a fossil organic materials (such as oil, coal and natural gas) - biomass fresh organic matter.
The chemical energy stored in plants and animals (that eat plants or other animals), or the waste they produce is called bioenergy. During conversion processes such as burning biomass releases its energy in the form of heat and produce carbon dioxide that comes to replace the carbon dioxide absorbed while the plant grew. In general it could be noted that the use of biomass for energy production is the reverse process of photosynthesis.

The energy drawn from biomass is a form of renewable energy. The use of this energy to recycle carbon and does not burden the environment with carbon dioxide, unlike fossil fuels. Of all the renewables, biomass has a unique capacity, is essentially a form of stored solar energy. Moreover, there is the possibility of processing of biomass and conversion of solid, liquid and gaseous fuels.

10 reasons to switch to solar energy

1. Reliability

It's a perfectly mature and proven technology.

2. Decentralization

The thermal energy produced at points of demand. This avoids the huge transmission losses through the electricity network.

3. Autonomy

Avoid huge expenditure on imported energy and insecurity due to dependence on imported energy resources. 70% of energy consumed, when the sun is free and there everywhere.

Solar Energy The New Era



"Turning to the sun and let the shadows behind you" (German proverb)

Solar energy is clean, inexhaustible, renewable, and mild. The sun is not controlled by anyone and is an inexhaustible domestic resource, which provides independence, security and predictability in energy supply.

There are two ways to build one solar power.

* Producing solar electricity through photovoltaic systems.
* Taking advantage of the warmth of the sun for heating, cooling and hot water with solar thermal systems.

For two decades the Greek consumers are familiar with solar panels for hot water. But that ignores the majority of consumers are not only technological improvements in solar thermal systems for heating water, but most other uses of solar technologies such as space heating, district heating housing, solar air conditioning and solar thermal electricity generation.

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 Technology




Active use of solar energy to serve human needs goes back to the dawn of human history where, directly or indirectly were operated mainly thermal energy to support daily activities.

Today, there is widespread use of the known solar collectors to heat water (solar water heaters) and rapidly evolving systems convert sunlight into electricity (PV).

Less known are the applications of solar systems that include Natural Illumination (Solatube ®), the Concentration of Solar Energy (systems CSP), the Photocatalysis (production of fuel cells for energy).


If we exclude applications Condensed Photocatalysis and Solar Energy - currently on station facilities and specialist interest and increased size - other forms of exploitation of solar energy is not only possible but also an ideal solution for the energy requirements of households and many professional and charitable buildings and facilities.

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.
