Countries worldwide consider renewable resources to contribute to reduction of global warming crisis and increase income. There has been growing interest in using solar energy to reduce reliance on electricity [1] . Saudi Electric Company started a policy to encourage solar energy installment and use via Photovoltaic (PV) system. Saudi Arabia unique geographical location and large area with mostly sunny climate condition made it a great candidate to invest in solar energy. The solar energy project or the new Saudi oil made by the crown prince Mohammad bin Salman bin Abdulaziz Al Saud. The Saudi solar energy project partnered with Softbank planned to provide the solar energy at an unbeatable price and a big profit, while reducing electricity prices for citizens. The solar investment will open the Saudi market for citizens’ investment, services and job opportunities. The foundation of King Salman Energy Park (Spark), managed by Aramco with investments worth around USD 1.6 billion (SAR6 billion) will enhance the level of economic diversification and support the growth of the private sector. The Council of Ministers approved the establishment of the King Salman Energy City (SPARK) in the Eastern Province. The Council also approved Saudi Aramco’s mandate to establish a company to develop the city’s infrastructure, manage its fixed assets and establish a company to operate, manage and maintain the city Operator. The city is located at the heart of the energy-related business between Dammam and Al-Ahsa, making it the third industrial city in Dammam. The city total area of 50 square kilometers, covers the first phase of 12 square kilometers. The city, which is being developed and operated by Aramco in partnership with the Saudi Industrial Cities and Technology Corporation (MODON), is enabling the supply chain associated with industries and services supporting the energy sector in the region and the Kingdom. The sustainability of investments guaranteed via providing an excellent infrastructure and an attractive environment for global investors, as well as providing integrated services. Aramco has initiated the establishment of the city and conducted studies and surveys with major and global suppliers. These efforts identified a number of key components to create an integrated and sustainable work environment that matches the best global centers [2] .

The government of Saudi Arabia announced plans to build a solar project with 200 gigawatts (GW) by 2030. The project will cost $200 billion to build the world’s largest solar project. The massive development plans of solar energy system in Saudi Arabia are to replace oil as energy sole source. Softbank’s Son said the 200 GW of solar would reduce the electricity cost by $40 billion while creating 100,000 jobs [3] . The current study used a questionnaire as an assessment tool to measure public awareness and approval of using renewable resources in Saudi Arabia specifically photovoltaic (PV) to reduce traditional energy use.

The study established based on descriptive analysis for questionnaire scored for 424 respondents. The questionnaire consisted of 13 questions and involved three categories to assess citizens of Saudi Arabia awareness about solar energy represented by photovoltaic use and other renewable resources to lower electricity bills. The arithmetic means and standard deviations for the participants’ response computed for multiple dimensions for questionnaire further assessment. About 11 questions scored as Likert-scale and contained five choices of “Strongly Agree (4.21 - above), Agree (3.41 - 4.2), Neutral (2.61 - 3.4), Disagree (1.81 - 2.60), and Strongly Disagree (1 - 1.8) [4] . While, two questions scored as four choices solar energy, wind energy, earth energy and all sources. Throughout the questionnaire, the participants asked to rate their responses regarding four subcategories as follow:

1) The overall tendency of installment of solar panel to reduce electricity bill;

2) The confidence of photovoltaic use ability to reduce electricity charge;

3) The awareness and approval of electricity bills regulation;

4) The suitable energy source where the respondents live.

The validity and reliability of the method tested using SPSS 16. The Cronbach Alpha test was run for the total number of instrument’s’ questionnaire and scored at 0.66 that represents a high level of reliability. Moreover, the validity of the instrument’s items calculated through Pearson score.

The global trend is toward the renewable energy resources and Saudi Arabia is no exception. Although Saudi Arabia has the world’s highest reserves for two energy sources, oil and natural gas [5] . There are many reasons that made Saudi Arabia plan to join the advanced world countries regarding energy resources, which include the global shift toward ecofriendly energy, to reduce global warming and to expand economic resources. Hence, the Saudi government announced plans to build a solar project with 200 gigawatts (GW) by 2030. To examine the public awareness on the solar energy utilization and investment we performed an electronic survey and recorded from 424 respondents. The questionnaire consisted of 13 questions scored responses of 424 individuals. The descriptive statistics in the form of arithmetic means and standard deviations for the participants computed for the multiple dimensions that been assessed through the questionnaire (Table 1). The questionnaire demographics showed that respondents’ age 94% were from 18 - 41years old. The respondents’ demographics youth age group explained by the nature of electronic survey that are mainly accessible by ages of 18 - 41 in Saudi Arabia. The results showed a tendency of agreement of Saudi public opinion toward the government encourage of solar panel installment. In addition, around more than 60% of the public agreed of the solar panel installment ability to reduce their electricity bills or make it moderate. Whereas, the public showed a neutral response regarding the question “the consumption of regular electricity will not be affected by the presence of photovoltaic counter”. Thus, public opinion is welcoming of the Saudi government introduction of solar energy (Table 1). The study emphasized the great awareness of Saudi public views analogues with the global trend and energy shift. However, the respondents use to photovoltaic system conditioned on

decreasing electricity bills as trade-offs associated with storing solar energy. However, the photovoltaic typical system in many countries works on sending the energy to utility grid [1] . In a sunny country like Saudi Arabia, most of the respondents (over 75%) thought of the sun as the source of energy where they live. Whereas, most of the respondents thought that all the sustainable energy sources (wind-sun-earth) might substitute electricity (Figure 1). The current renewable energy resources status in Saudi Arabia represented in Figure 2, where most respondents assumed the solar energy feasibility where they lived considering the sunny country nature. The government projects related to solar energy shown in Figure 2. The Saudi Arabia capital city (Riyadh) has two photovoltaic (PV) projects, one with 3.5 MW and the other has 1.8 MW. The smallest PV project is located in the Saudi Farasan Island that has 500 KW. While, King Abdullah University of Science and Technology (KAUST), at the city of Thuwl has it is own power of PV with 2 MW, whereas, the highest power comes from concentrated solar power (CSP) with 600 MW in Duba. While, Saudi Arabia current projects involved photovoltaic system is in Dhahran with 10 MW size and in progress the greatest PV power in Sakaka with 300 MW and the smallest in Tabuk with 1 MW. The only wind renewable source located in Tabul

named Midyan wind, with power of 400 MW. Thus, the PV system will be a vital investment in Saudi Arabia near future with great approval of public and government system in case of assuring electricity bill reduction and solar energy tradeoff system (Figure 2).

The global warming resulted from oil energy and carbon emission in addition to economic necessity for various investments redirects Saudi Arabia public and government figures toward the renewable resources use and investment. The use of crude oil is not cost effective anymore, considering the environmental and the refining cost. The current study aimed to assess the citizens’ acceptance and awareness of solar energy use represented by photovoltaic system (PV). The respondents showed a significant confidence of photovoltaic use ability to reduce electricity bills and the public opinion in agreement with renewable resources use via solar, wind or earth energy. The sunny nature of Saudi Arabia reflected on the public prescriptive of seeing the solar energy or PV as a potential

source of energy. The new Saudi oil expected to revolutionize the economy and public awareness of energy use rationalization. The only shortcoming is that PV system is still immature and people need to learn more about it to utilize the maximum level.
