Saudi companies in Saudi Arabia launched 7 new Solar energy projects as a part of Saudi Arabia's vision 2030. These projects will diversify the economy and reduce the reliance on fossil fuels, thus proving to be reliable renewable energy sources.
Conergy believes that Saudi Arabia and other countries in the Middle East have a lot of market potential for solar power due to their desert conditions with more sunlight. In Saudi Arabia, Conergy fulfilled three projects surrounding installing solar panels on rooftops. The energy production totaled 2.5 MW.
Saudi Arabia has the potential to supply its electrical needs solely with solar power. [citation needed] As the largest oil producer and exporter in the world and one of the largest carbon dioxide producers Saudi Arabia would set an important precedent in renewable energy by shifting to solar power.
The upcoming projects, such as the Ar Rass II, Al Sadawi, Saad II, Al Masa’a, Al Henakiyah 2, Tabarjal, and Amaala solar power plants, collectively contribute to the country's goal of achieving 58.7 GW of renewable energy capacity by 2030, with 40 GW coming from solar PV.
Approach used for providing solar energy includes the utilisation of a solar tower system with a solar reactor atop the solar tower or preheater tower in a conventional cement plant. Analysis considered thermal energy substitution ranging from 100% to 50%.
Gonzalez and Flamant (2013) designed a hybrid model that uses solar and fossil fuel energy to fulfill the thermal energy requirement for cement manufacturing. Concentrated solar thermal (CST) is a potential replacement for 40%–100% of the thermal energy needed in a conventional cement plant.
This study shows that it is feasible to implement concentrated solar energy for the calcination process of cement production. Solar resource for the chosen plant location permits operation for an average of 12 h per day. 9 h of these 12 h are useable, with the remaining 3 h being utilized to heat up and cool down the solar reactor.
Concentrated solar power system is designed for cement industry. Substitution of required thermal energy ranging from 100% to 50% is studied. 7600 heliostats with 570 ha land required for 50% conventional energy replacement with solar energy. Selected conventional cement plant could save 419 thousand tons of CO 2 annually.
Stakeholders in Jordan's construction industry were asked to assess their degree of awareness and knowledge of green building and sustainability, based on their own experiences and understanding, to get insight into how well-informed they are.
As a solution to the lack of sustainable construction in Jordan, manufacturers and suppliers of building materials, and program and project developers, are recommended to invest in environmentally friendly buildings and materials and recycle construction and demolition waste . 5. Conclusions
Results from the interviews showed several reasons for the low adoption of sustainable building practices in Jordan, including lack of knowledge and education, lack of support from stakeholders, and limited rehabilitation and scientific research .
Jordan's private and public sectors' perceptions of green building construction in Jordan can be influenced by the findings of this study, which helps promote the notion of sustainable building construction in Jordan to the research participants.
