Ethiopia has a vast renewable energy potential in the context of hydro, wind, solar, and geothermal energies. The unsustainable use of biomass coupled with drought has caused a paradigm shift towards wind, geothermal, and solar energies. There have been significant strides by the Government of Ethiopia to actualize these potentials in the context of developing massive projects in these aforementioned areas with the private business sector in the goal of jettisoning the industrial base of Ethiopia in conjunction with increasing the installed power capacity from 4,300 MW to 17,346 MW by 2020. The major challenge still lies in assessing the comprehensive renewable energy resource potential of Ethiopia including the lack of local content development in the context of establishing an industrial base. There have been notable initiatives by the Government of Ethiopia to adhere to the Paris Climate Accord in conjunction with the Green Growth framework and Sustainability Development Goals. However, the top down approach of grand targets to the various regions is not the pragmatic approach to solving the Achilles heel of energy poverty. A more plausible approach is from the bottom up, whereby energy frameworks and policies are generated by conducting a needs assessment of a specified region. The appropriate technology concept needs to be reflected in the innovation aspects of renewable energy technologies. There has to be a framework of translating invention to innovation by actualizing the tripartite structure of Government, Academia, and Industry.

This research investigates the factors that potentially affect public attitudes and their adoption of renewable energy technologies for electrical energy production in Afghanistan. The study is carried out with a survey from Kabul and its neighboring provinces including Logar, Maidan Wardak, Nangarhar, Ghazni, Parwan & Kapisa provinces. We used a random sampling process to collect data using a web-based questionnaire. The survey was well designed to highlight conveniently the public understanding, willingness, and attitudes toward adopting renewable energy technologies (RETs). The outcome of the survey is then evaluated to discover the most potential factor affecting public acceptance of RETs. The results declared that the educational level, expertise in RETs, and income of respondents are positively related, while the age of respondents is negatively related to the public willingness on the use and investment in RETs. The majority of respondents have used one type of RETs, however, 23 % of respondents have not used any type of RETs. Study shows that the RETs use and access to grid electricity are reversely related, where the access is lower, the RETs use is higher and vice versa. Most of the respondents were not well informed and most disagreed with the government policies on RETs, therefore, public awareness programs on RETs and government policies are recommended. The majority of respondents were willing to invest in RETs, therefore, the government should commit itself and support private sectors to invest in RETs and take part in its development.

The idea of achieving energy security and lowering the dependence on the global hydrocarbon market is at the top of the agenda in many countries. Most of them consider switching from traditional energy sources to renewable ones as one of the ways to reduce fuel import. This concept absolutely conforms to one of the UN Sustainable Development Goals (Goal no. 7, “Affordable and Clean Energy”). In May 2019, the Government of Uzbekistan Republic adopted the law on the Use of Renewable Energy Sources (RES). By 2030, Uzbekistan is going to increase the share of RES in the total structure of electricity generation up to 25 % (currently it is at 10 %), by building solar and wind farms with a total installed capacity of 5,000 MW and 3,000 MW, respectively. The energy-deficient Bostanliq district of the Tashkent region has become one of the places of interest, where transport infrastructure, recreation services, and renewable energy will be developed. The purpose of this study was a multivariate analysis, considering the meteorological, ecological, and socio-economic characteristics of the Bostanliq district, leading to the selection of the optimal location for the wind farm. The assessment map based on the results of this analysis made it possible to identify areas that are most suitable for the location of wind power plants. The assessment method, that was used in this work, is also applicable to other regions of the world.

The need for electrical energy in Indonesia continues to increase every year. In line with the increase in the electrification ratio to 100% in 2050, the demand for electrical energy is projected to reach 7 times, namely 1,611 TWh. To meet electricity needs, the government has created a 35 GW program, but one of the largest contributors to power generation fuel is coal with a share of 58% or around 50 GW which is estimated to be exhausted within the next 68 years. For this reason, innovations are needed in terms of fulfilling electrical energy by utilizing renewable energy potential, one of which is hydro energy, which is 45,379 MW from a total resource of 75,091 MW. Therefore, from this potential, innovations related to renewable energy have been created, namely the Hybrid Portable Underwater Turbine Hydro and Solar Energy hybrid power plant. This power plant uses an undersea current as a propulsion which is hybridized with solar power to increase the production of electrical energy. This power plant has the advantage that there is an Underwater turbine design that is resistant to underwater flow and a water flow direction to increase the work efficiency of the underwater turbine. From the test results, the portable Underwater turbine hydro produces 950 W in a day. Solar panels produce 65.6 Watts a day. The total hybrid that can be produced is 1.02 kW a day. In its implementation it can supply loads of up to 900 (VA) such as lamps, fans, TV, etc. This hybrid power plant can be a solution to help meet electricity needs in the area around Dusun Dongol, Sidoarjo through alternative electrical energy innovations.

Water Energy Nexus

The water-energy nexus, together with the need for sustainable management of these interconnected resources, has attracted growing attention from the scientific community. This paper focuses on this nexus from the point of view of the energy that is required by wastewater treatment plants, which are intensive energy consumers and major emitters of greenhouse gases. The main objective of the study is to investigate the possible use of a wastewater plant’s internal chemical, potential, and kinetic energy, and the addition of external renewable technologies with a view to achieving clean energy consumption and reducing greenhouse gas emissions. For this purpose, an analysis is made of the feasibility of introducing alternative technologies—anaerobic digestion, hydraulic turbines, wind turbines, and photovoltaic modules— to meet the plant’s energy needs. The plant chosen as case study (Jinamar plant, Canary Islands, Spain) has an energy consumption of 2956 MWh/year, but the employed methodological framework is suitable for other plants in locations where the renewable energy potential has previously been analyzed. The results show that a renewable energy production of 3396 MWh/year can be obtained, more than enough to meet plant consumption, but also confirm the need for an energy storage system, due to seasonal variability in energy resource availability. In terms of climate change mitigation, the emission of 2754 tons/year of greenhouse gases is avoided. In addition, the economic viability of the proposed system is also confirmed.

As we know, more and more energy are required to meet the demands of society, and this has forced the government to review the economy and energy policies. The solar energy resource is abundant in China, which provides a good foundation with the utilization of solar energy. In China, there is a Silica Valley in Beijing, an Optics Valley in Wuhan, and also an Electricity Valley in Baoding. First, the only domestic national industry base of renewable energy and equipment is located in Baoding National New and High-tech Industry Zone. Secondly, there are great advantages on the photovoltaic industry, the wind power generation and the power transmission and transformation equipment, corresponded with the Yingli Green Energy Holding Company Limited, Zhong Hang Huiteng Wind Power Equipment Corporation Limited and Tian Wei Group Corporation Limited, respectively. Then it is a natural choice for the local government to develop the renewable energy in the readjustment of industry structures. This paper deals with the utilizations and prospects of solar energy.

Currently, there are an estimated 1.3 billion tonnes of municipal solid waste (MSW) generated per year globally, and this quantity is predicted to increase to 2.2 billion tonnes annually by 2025. If not well treated, this rapid growth of waste products can lead to socio-economic and environmental problems. Waste is potentially a misplaced valuable resource that can be converted and utilized in different ways such as renewable energy resources for the realization of sustainable development. Presently, waste-to-energy technologies (WtETs) are considered to be an encouraging advanced technology that is applied to convert MSW into a renewable energy resource (methane, biogas, biofuels or biodiesel, ethanol, syngas, or alcohol). WtETs can be biochemical (fermentation, anaerobic digestion, landfill with gas capture, and microbial fuel cell), thermochemical (incineration, thermal gasification, and pyrolysis), or chemical (esterification). This review mainly aims to provide an overview of the applications of these technologies by focusing on anaerobic digestion as biological (nonthermal) treatment technologies, and incineration, pyrolysis, and gasification processes as thermal treatment processes. Landfill gas utilization technologies, biological hydrogen production processes, and microbial fuel cells also are assessed. In addition, the contemporary risks and challenges of WtETs are reviewed.

The One

Seventh goal of the "Sustainable Development Goals (SDGs)" is clean and affordable energy to increase the proportion of renewable energy. However, power plants in Indonesia are still dominated by non renewable energy. Therefore, it is necessary to have renewable energy technologies such as photovoltaic that can be installed on-site in buildings as an alternative clean electricity supplier. Even though Indonesia has abundant sun energy, domestic photovoltaic development is relatively slow. This research aims to identify obstacles to the application of photovoltaic as an on-site electrical system in Indonesia by spreading questionnaire to experts and users. Each question in the questionnaire is related to the understanding of the three pillars of sustainability (environment, social, and economic) related to on-site photovoltaic. The results of the data will be tested using the one sample t-test method to identify the environmental barriers, social barriers, and economic barriers. The results of this study indicate that the constraints of photovoltaic as an on-site power plant are generally dominated by social and economic barriers. Meanwhile, environmental barriers are recessive.
