Hydroelectric power is a form of renewable energy that harnesses the power of water to generate electricity. It works by using the kinetic energy of falling water or the movement of water through a turbine to spin a generator, which produces electricity. The water used in hydroelectric power can come from various sources, such as rivers, lakes, and reservoirs.
The process of generating hydroelectric power begins with the construction of a dam or a water diversion structure, which is used to create a large reservoir. Water is then released from the reservoir, and its potential energy is converted into kinetic energy as it falls down a steep incline. This moving water then drives the turbines, which spin the generator and produce electricity.
Maritime transport has traditionally relied on fossil fuels, but alternative energy sources are becoming increasingly important because of their potential to reduce greenhouse gas emissions and improve air quality. Some alternative energy sources that can be used in maritime transport include:
Biofuels
Biofuels are alternative energy sources produced from renewable organic materials such as vegetable oils, animal fats, and waste. They are being explored as a potential alternative to traditional fossil fuels in maritime transport due to their lower carbon footprint and their ability to reduce greenhouse gas emissions.

A colocated solar park is a facility that combines solar photovoltaic (PV) panels with a battery energy storage system (BESS) to provide reliable and efficient electricity to the grid. The optimal ratio of PV to BESS in a colocated solar park depends on several factors, including the location of the facility, the size and type of the PV panels and BESS, and the expected energy demand.
One important factor to consider is the amount of solar insolation, or sunlight, that the location receives. In areas with high solar insolation, a higher ratio of PV to BESS may be more efficient, as the PV panels will produce more electricity than the BESS can store. In areas with lower solar insolation, a lower ratio of PV to BESS may be more appropriate, as the BESS will be able to store more of the electricity produced by the PV panels.

HJT (heterojunction) panels, also known as HIT (heterojunction with intrinsic thin layer) panels, are the new generation of solar panels. They are known for their high efficiency and improved performance under different weather conditions, making them an attractive option for residential and commercial solar installations. But what sets them apart from traditional solar panels and why are they becoming increasingly popular?

Πολλοί είναι εκείνοι οι οποίοι προσπαθούν να προβλέψουν ποια θα είναι η κυρίαρχη τεχνολογία παραγωγής ηλεκτρικής ενέργειας έως το 2050. Το μόνο σίγουρο είναι ότι το μείγμα παραγωγής ηλεκτρισμού δεν θα αποτελείται πλέον από μία κυρίαρχη τεχνολογία, αλλά πολλές διαφορετικές, με συγκεκριμένες εφαρμογές που θα καλύπτουν συγκεκριμένες ανάγκες σε συγκεκριμένες συνθήκες (γεωγραφικές, περιβαλλοντικές, προφίλ κατανάλωσης, κτλ.).
Όσον αφορά τις διαθέσιμες τεχνολογίες που μετατρέπουν την ηλιακή ενέργεια σε ηλεκτρισμό, αυτές είναι δύο, τα γνωστά φωτοβολταϊκά συστήματα (Solar PV ή Photovoltaics) και τα συστήματα ηλιοθερμικής ενέργειας, τα λεγόμενα CSP (Concentrated Solar Power). Από τις δύο αυτές τεχνολογίες τα Φ/Β συστήματα έχουν κυριαρχήσει παγκοσμίως, στην συντριπτική πλειοψηφία των περιπτώσεων και με αυτά θα ασχοληθούμε στο παρόν.
Read moreSolar energy has been growing rapidly in recent years as the sun is one of the most efficient, economical, and sustainable sources of energy. However, are we making the most of this inexhaustible source?
Hearing solar energy, everyone’s thoughts turn to ground-mounted solar panels on some barren land far away from developed areas. This is because most photovoltaic installations are located in such remote areas because of the easier and more economical installation. Installation in urban areas, on the roofs of buildings, is more difficult and costly.
