Significance The project aims to generate up to 200 gigawatts by 2030, creating 100,000 jobs in Saudi Arabia. Renewable energy was also a key focus in the United Arab Emirates (UAE), at its ‘Sustainability Week’ in January, one of the largest gatherings of business and political leaders in the region for this purpose, which highlighted an IHS forecast that solar power would rank third as an energy source in the region by 2035. Impacts Countries eliminating energy subsidies will attract the most investment in renewables. Natural gas will remain the regional fuel of choice for power generation through to 2035, increasing its share in the energy mix. Solar is likely to overtake hydropower as the largest source of renewable power in the Middle East by 2035. Even by 2035, solar power (both photovoltaic and concentrated) will still account for less than 6% of power generation.

Significance Energy subsidies are a major blockage to wider adoption of renewable energy in the Gulf Cooperation Council (GCC), where pricing bids have recently broken world records. The low bid for Saudi Arabia’s first solar project in early October was just 1.79 cents per kilowatt hour (kWh) -- down from the previous best offer on a United Arab Emirates (UAE) solar project in 2015. Impacts Local renewables companies could begin to grow their businesses in the GCC. The lack of suitably trained Gulf nationals will limit the impact on private sector activity and employment. The rising cost of debt could increase the price and terms of bids for renewables projects, making them relatively less attractive. If maintenance costs in desert environments turn out to be higher than expected, projects could flounder.

Forecasting of large-scale renewable energy clusters composed of wind power generation, photovoltaic and concentrating solar power (CSP) generation encounters complex uncertainties due to spatial scale dispersion and time scale random fluctuation. In response to this, a short-term forecasting method is proposed to improve the hybrid forecasting accuracy of multiple generation types in the same region. It is formed through training the long short-term memory (LSTM) network using spatial panel data. Historical power data and meteorological data for CSP plant, wind farm and photovoltaic (PV) plant are included in the dataset. Based on the data set, the correlation between these three types of power generation is proved by Pearson coefficient, and the feasibility of improving the forecasting ability through the hybrid renewable energy clusters is analyzed. Moreover, cases study indicates that the uncertainty of renewable energy cluster power tends to weaken due to partial controllability of CSP generation. Compared with the traditional prediction method, the hybrid prediction method has better prediction accuracy in the real case of renewable energy cluster in Northwest China.

Renewable energy generation is no more an alternative rather it becomes a choice for the power generation to meet the upcoming energy demand. Considering the non- renewable energy unavailability, as well as, the environmental impact, renewable energy should be the first choice. Most of the power generation in Bangladesh comes from nonrenewable energy and a noticeable amount of energy is imported from abroad. As a developing country, it is not cost-efficient and never ensures energy security. To ensure long-term energy security, it is time to shift power generation from nonrenewable to renewable energy generation. This paper presents an approximate calculation for the renewable power generating plant cost and returning year. The cost calculation is done in the context of Bangladesh.

This critical review report highlights the enormous potentiality and availability of renewable energy sources in the Gulf region. The earth suffers from extreme air pollution, climate changes, and extreme problems due to the enormous usage of underground carbon resources applications materialized in industrial, transport, and domestic sectors. The countries under Gulf Cooperation Council, i.e., Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates, mainly explore those underground carbon resources for crude oil extraction and natural gas production. As a nonrenewable resource, these are bound to be exhausted in the near future. Hence, this review discusses the importance and feasibility of renewable sources in the Gulf region to persuade the scientific community to launch and explore renewable sources to obtain the maximum benefit in electric power generation. In most parts of the Gulf region, solar and wind energy sources are abundantly available. However, attempts to harness those resources are very limited. Furthermore, in this review report, innovative areas of advanced research (such as bioenergy, biomass) were proposed for the Gulf region to extract those resources at a higher magnitude to generate surplus power generation. Overall, this report clearly depicts the current scenario, current power demand, currently installed capacities, and the future strategies of power production from renewable power sources (viz., solar, wind, tidal, biomass, and bioenergy) in each and every part of the Gulf region.

Electricity Bill

The Ottawa Renewable Energy Cooperative is considering installing solar modules on the roofs of two buildings while they stay connected to the public electricity grid. Solar power produced over their own needs would be sent to the public electricity grid for a credit on their electricity bill. When they need more power than they are generating, these buildings would purchase electricity from the grid. In addition to paying for the electricity they purchase, they would be subject to a “demand charge” that applies each month to the hour during which their consumption is at a peak for that month. Any electricity consumed during that peak hour would be charged at a rate about 100 times the rate for other hours. The case addresses three questions: (1) Is it profitable for these organizations to install solar on their roofs? (2) Can profitability be increased by adding a battery? and (3) How sensitive is profitability to uncertainty in future electricity prices? The case shows how the answers to these questions depend on the profile of hourly electricity consumption during the day, which is very different from one building to the other.

Technical Issues

PurposeAs the impacts of climate change become more evident, the need to adopt new ways of constructing buildings becomes more urgent. The Earth has experienced hotter climates globally for the last 70 years (NASA, 2019), and this has resulted in unprecedented levels of bushfire in Australia, flooding in the UK and drought in Africa in early 2020 (World Resources Institute, 2019). The predictions are for increased temperatures globally and increasing carbon emissions from fossil fuel consumption. There is a critical need to reduce the reliance on fossil fuels as a building energy source (WCED, 1987). Existing renewables focus on solar, wind and wave power, where technological improvements have increased efficiencies (Hinnells, 2008). Uptake of the technologies is variable depending on location and willingness to adopt renewables. As well as further uptake of existing renewable energy sources, we need to look wider and across traditional discipline groups, at new technologies such as biotechnologies. One potential energy source is biofuels. Biofuels are produced from biomass, which is algae. In 2016, the BIQ, a four-storey apartment building, was constructed in Hamburg, Germany. The BIQ features glazed façade panels filled with algae to produce biomass and solar thermal energy. Could algae building technology (ABT), in the form of façade panels, offer a new renewable energy source?Design/methodology/approachWhat are the technical issues associated with Algae building technology? This qualitative research sought to identify what technical issues likely to arise in terms of algae building construction, operation and maintenance. Semi-structured interviews with 24 experienced built environment professionals in Australia were undertaken in 2016 to assess the most likely issues that could arise with this new innovative technology.FindingsAs a result, a greater understanding of the range of technical issues related to design, construction, maintenance and operation were identified, as well as the perceived importance of those issues. It was possible to identify the top ten technical issues built environment professionals are concerned about with regard to ABT. The results can inform future designers of ABT.Research limitations/implicationsThis research was restricted to the views of 24 experienced built environment practitioners in Sydney, Australia. None of whom had direct experience of Algae Building Technology. Though knowledgeable, a greater number of interviews may have identified other technical issues.Practical implicationsNo guidelines exist for Algae Building Technology, and this research identifies a comprehensive range of technical issues that need to be considered for the technology to function at optimum levels. As such, this is a starting point for built environment professionals who may be asked to provide professional advice and guidance.Originality/valueTo date, no evaluation of Australian based built environment professionals has been conducted into the technical issues associated with Algae Building Technology.
