يهدف هذا البحث إلى تقييم الأداء الطاقي و البيئي لمجموعة من التقنيات المتجددة شائعة الاستخدام في القطاع السكني، و ذلك من خلال تطبيقها برمجياً على وحدة سكنية نموذجية تماثل إلى حدٍ ما مواصفات الوحدات السكنية المحمية، و مقارنتها مع التقنيات التقليدية. التقنيات المتجددة التي يتضمنها البحث هي: سخان ماء شمسي منزلي حر من نوع المجمع ذو الأنابيب الزجاجية المفرغة، نظام كهروضوئي، مضخة جيوحرارية، بالإضافة إلى أربع أنظمة هجينة تتضمن سخان الماء الشمسي مع ثلاثة أنواع من الأنظمة الداعمة (مازوت، كهرباء، غاز طبيعي) كل على حدا، و نظام يجمع بين المضخة الجيوحرارية و النظام الكهروضوئي لتشغيلها.
This study evaluates the energetic and environmental performances of a group of renewable energy technologies widely used in the residential sector, by applying them to a typical housing unit that resembles to some extent our local housing units. Then comparing those technologies with the conventional ones. The renewable energy technologies used in this study are: thermosiphon domestic solar water heater with evacuated tube collector, PV system, geothermal heat pump (GSHP), in addition to four hybrid systems that include: the solar water heater with three types of backup systems (diesel, electricity and natural gas) and a hybrid system that combines between the geothermal heat pump and a PV system to operate it.

As a result of the shortage of traditional energy sources, the world and
advanced countries particularly have started conducting the researches and studies
to find or create other energy sources different to those in use nowadays.
Recently, those
countries were involved in this process have managed gradually
to accomplish a turning point in the globe history by achieving such a prominent
goal in reaching a different new form of energy is called the "Renewal Green energy
sources" that can secure the sufficient energy without being worried of getting
demolished by the time. Simultaneously, contributes considerably in protecting the
global environment. These sources are:
Geothermal energy, solar energy, Oceans energy, Wind energy, Water energy,
Biomass energy Being an essential part of the world, Syria will inevitably suffer in
the future from the lack of energy problem eventually.
The rising in the world’s population leads automatically to the rising in water demand. As a consequence
the lack of drinking water increases Currently, approximately 1.2 billion people globally (one-sixth of the
world’s population) do not have acc
ess to adequate clean water. Since a large part of the world’s
population is concentrated in coastal areas, the desalination of seawater seems to be a promising solution,
especially in our Arab world. An innovative stand-alone solar desalination system could be used to
produce drinking water from seawater or any brackish water sources. The great advantage of such a
system is that it combines efficient desalination technology, reverse osmosis, with a renewable energy
source. The main goal is to improve the technical feasibility of such systems, There are many advantages
of this coupling with RE resources ; first of all we separate the drinking water from the electricity grid
and its faults, save burning the fossil fuel and its emissions, and provide fresh water to remote
communities that do not have sufficient traditional energy sources. But as we see in this study we don’t
have economic benefit; because these projects depend on the electricity cost in each country and the
location and its solar specifications.
We designed and implemented a small laboratorial model for PV-RO (Photo-Voltaic Powered Reverse
Osmosis) to recognize the performance for seawater and brackish water, we faced some problems such as
embargo on Syria; so have done project using affordable local potentialities, but we craved to keep the
principle of operation, so we make it for the tap water which close to brackish.
The integration of various renewable energy sources as well as the liberalization of
electricity markets are established facts in modern electrical power systems. The increased
share of renewable sources within power systems intensifies the supply
variability and
intermittency. Therefore, energy storage is deemed as one of the solutions for stabilizing
the supply of electricity to maintain generation-demand balance and to guarantee
uninterrupted supply of energy to users. In the context of sustainable development and
energy resources depletion, the question of the growth of renewable energy electricity
production is highly linked to the ability to propose new and adapted energy storage
solutions. Recent advancements in hydrogen technologies and renewable energy
applications show promise for economical near to conversion to a hydrogen-based
economy. As the use of hydrogen for the electric utility and transportation sectors. This
paper briefly discusses provides a historical perspective for hydrogen production and the
role of hydrogen as an energy carrier, discusses hydrogen economy, the process of
electrolysis for hydrogen production (especially from solar and wind technologies).
A comprehensive techno/socio/economic study of long term hydrogen based
storage systems in electrical networks is addressed. the excess produced hydrogen during
high generation periods or low demand can be sold either directly to the grid owners or as
filled hydrogen bottles. The affordable use of Hydrogen-based technologies for long term
electricity storage is verified. The results indicate that ample resources exist to produce
Hydrogen from wind and solar power. However, hydrogen prices are highly dependent on
electricity prices.
In this paper, we have suggested the STATCOM
(STATic synchronous COMpensator) to connect PV-solar (or
wind) frame to the power system for the Hassia industrial city
which we chose as a case study. This frame will provide the city
with the required power, improve the power quality and inject
the redundant to the power system.
The geography of energy focuses on studying the energy
resources from its specification, variety, and geographical distribution, in
the world in general and in each country as a political entity. As well as,
it studies the effective factors in pro
ducing, transporting and distributing
and consuming energy, by depending on the methods of the economic
geography, such the regional method, the objective method, and the
historical method, as well as some modern methods which specially study
the energy as method of systems analysis, and the factors analysis
method, also, it depends on the mathematical and statistical methods to
scale energy efficacy, and density uses, and the cost of transportation.
