The rapid development of wind Energy Worldwide

The global market for wind turbines is expected to almost double this year. Last year, the market grew by 80% with 620 new megawatts of installed capacity.

Especially the sector of offshore wind is considerably enhanced, and several governments are turning in this direction not to deal with local responses to terrestrial wind farms.
The offshore market is expected to grow by an average of 43% per year in the period 2010-2015, as noted by analysts.

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.

'Green'energy from artificial photosynthesis

Scientists at MIT have managed to genetically modify a virus, which after the conversion can perform its natural photosynthesis process.
The process of photosynthesis allows plants to convert inorganic substances into nutrients to feed.

The researchers altered the virus genetic M13, that through the photosynthetic apparatus can produce clean energy.

Altered the virus so that it can use solar energy to split water molecules into oxygen and hydrogen and then use the hydrogen as an energy source.

Now, the next stage of research is to be able to create large and efficient systems based on these artificial photosynthesis, which would produce unlimited quantities of environmentally friendly energy.

The effort to develop methods of artificial photosynthesis has for decades one of the great dreams of the alternative fuel industry.
