Challenges related to the management of current world energy resources strongly emphasize the necessity to progressively increase renewable energy sources (RES) share in meeting electricity demand. To design efficient and sustainable energy systems, it is mandatory to consider both electrical energy generation characteristics and environment preservation targets. The main objective of intensifying RES deployment nowadays is to concurrently mitigate fossil fuels depletion and environment degradation. However, to ac...

The spectrum of energy resource depletion in the coming years has been a serious alarm signal and has led to the identification of the possibilities for substitution of depleting resources, the reduction of environmental imbalances caused by the exploitation, processing and utilization of the resources used up to now. This alarm signal has led mankind to operate with a new concept, the energy security concept. For most specialists, energy security means producing the necessary energy in their own country and reduc...

Over the last decade, due to the rapid increase in energy consumption, sustainability has become an increasingly important concern among developers and software and hardware users. The digital era brings about a fast and continuous production of information, whose management becomes a challenge for both large companies and users worldwide, in their private environment. The huge amount of data needed to carry out day-to-day operations means a continuing need for increased storage space, which translates into high h...

Wood was the most common source of energy on earth, being gradually replaced by fossil fuels. Given that the wood used in the generating stations comes from properly managed forests, then the carbon emitted from the chimneys can be annihilated by the carbon that is absorbed and used by the freshly planted trees. Wood can therefore be considered as carbon neutral. It remains to be seen if this theory is actually verified. Once it was decided to classify wood as a renewable source, its consumption increased exponent...
