Algeria has enormous renewable energy potential. However, fossil fuels remain the main electricity generation source, and the country is the third largest CO2 emitter in Africa. Algeria is also particularly vulnerable to climate change. Therefore, a set of actions related to energy, forests, industry and waste sectors have been programmed, over the period 2015–2030, and the government action program has given priority to promote renewable energy. In this sense, Algeria is committed to significantly promote investment in renewable energy, during the period 2020–2030. Thus by 2030, renewable electricity production capacity will achieve 22,000 MW, representing 27% of total electricity generation. This paper analyzes the electricity generation measures implemented in Algeria to reach the required energy mix, the legislative framework, financial aid, the feed-in tariff system, the tax incentives, and the tender and auctions undertaken. The analyses reveal that, although the electricity price premium policy has not been revoked, the newly enacted tender scheme is designed to become the standard procedure for launching renewable energy projects in Algeria in the coming years.

Until the middle of 20th century, there was a strong conviction that the next century would be the age of renewable and nuclear energy resources. However, at present, the whole world is dependent on fossil fuels to satisfy their energy need. Environmental pollution and global warming are the main issues associated with the use of fossil fuels for electricity generation. As per the report of US Energy Information IE Outlook 2016, coal, natural gas, and petroleum share nearly 67.2% of global electricity generation whereas renewable energy shares only 21.9%. This share is only one-fifth of the global electricity demand. According to the IEA 2016 Medium Term Renewable Energy Market Report, worldwide power production capacity of marine was only 539 MW in 2014, and to reach at a level of 640 MW, it will take 2021. The oceans cover about 70% of the Earth and acts as the largest thermal energy collector. A recent study reveals that global development capability of ocean energy is approximated to be 337 GW, and more than 885 TWH of electricity can be produced from this potential.

Stable Source

The mining is an energy-intensive industry that requires a stable source of electricity. With the increase in demand for minerals and the decrease in grades, the demand for energy is expected to increase by 36% by 2035. This increased demand relies on the use of fossil fuels since the electricity produced and purchased in the mining companies is Based primarily on fossil fuels, the costs of solar and wind energy storage systems have fallen on an unprecedented scale, encouraging mining companies to test these technologies. Among the influencing factors of the use of renewable energy, is the benefit to the community in the stage of operation and closure or post-closure of a mining project, the next factor is the profile of electricity consumption or demand is important for the calculation of its storage or not, of the renewable energies to be used. As a third factor is the calculation for consumption in the processes. The penetration ranges will determine if its energy storage is possible, and if it is possible to use hybrid control (solar - wind), for this the use of digital tools such as the Holmer program is important, it is an important tool that technical and economical. The government must have a perspective that helps on regulatory issues necessary to promote renewable energy projects with different incentives and interests according to the mining context.

Energy Technologies

The levelized costs of electricity generation for renewable energy technologies differ and fluctuate depending on factors including capital costs, operation and maintenance costs, utilization factors, and economic lives. In addition to these factors, In the case of fossil fuels, prices and heat rate are also responsible for fluctuations. There is a global movement in favor renewable energy. Many countries have announced carbon-free electricity within the next 30–40 years, which implies massive expansion of renewable energy technologies. The newer investment trends in electricity generation technologies indicate the same. Technological breakthroughs and cost reductions of energy storage technologies would further favor renewable energy technologies and would decrease their intermittency hurdles. Developments that expand the scaling effect of renewable energy and the potential improvement in efficiency through continued research and development could bring the cost of renewable energy further down in the future. When the levelized costs of electricity generation are estimated, the declining trends of renewable energy costs are observed and can to a large extent (but not fully) be explained by certain potential drivers. Particularly for wind and solar, these drivers include technological innovation/improvements that have increased efficiency, policy supports such as research and development funding, economy of scale both on the manufacturing of equipment (solar panels, wind turbines) and installation of plants, and monopoly rent dissipation due to increased number of manufacturers and suppliers. Competition among equipment manufacturers and project developers may also contribute to cost decline as could cost reduction through improved product efficiency related to technological improvements and innovations.

Abstract Indonesia has a large amount of energy consumption, domestically and industrially. Indonesia’s energy mix is still dominated by fossil fuels and coals, with the percentage of 35.64% and 50% respectively in 2020. This is caused by Indonesia’s rich supply of oil and coal, even though experts have predicted that these supplies will run out in 10 years ahead. One option to preserve Indonesia’s energy security is to start using renewable energy. Indonesia’s renewable energy potential is predicted to be around 443 GW of installed capacity, and already made renewable energy mix percentage target of 23% in 2025 and 31% in 2050 in their National Energy Plan. However, Indonesia’s renewable energy percentage in their 2020 national energy mix is only 14.71%. Therefore, to reach their national renewable energy target, Indonesia needs to solve their problems by finding the right actions and strategies in their energy management through stakeholders such as the government, public, and investors. This review will be made by using the literature based research method.

Energy Needs

Renewable energy from the sun—which includes solar, wind, and water energy— can meet all of our energy needs and will allow us to eliminate our dependence on fossil fuels for electricity production. At least, that is the “Siren song” that seduces many people. Amory Lovins, the head of the Rocky Mountain Institute, has been one of the strongest proponents of getting all of our energy from renewable sources (what he calls “soft energy paths”) (1) and one of the most vociferous opponents of nuclear power. A recent article in Scientific American proposes that the entire world’s needs for power can be supplied by wind, solar, and water (2). Is this truly the nirvana of unlimited and pollution-free energy? Can we have our cake and eat it, too? Let’s take a critical look at the issues surrounding solar and wind power. Let me be clear that I am a proponent of solar energy. I built a mountain cabin a few years ago that is entirely off the grid. All of the electricity comes from solar photovoltaic (PV) panels with battery storage. The 24 volt DC is converted to AC with an inverter and is fed into a conventional electrical panel. It provides enough energy to power the lights, run a 240 volt, three-quarter horsepower water pump 320 feet deep in the well, and electrical appliances such as a coffee pot, toaster, and vacuum cleaner. But I am not implying that all of my energy needs come from solar. The big energy hogs—kitchen range, hot water heater, and a stove in the bedroom—are all powered with propane. Solar is not adequate to power these appliances. In 2010 I also had a 2.5 kW solar PV system installed on my house that ties into the utility grid. When the sun is shining, I use the electricity from the solar panels, and if I use less than I generate, it goes out on the grid to other users. If it does not produce enough for my needs, then I buy electricity from the grid.

There are many issues with the continued use of fossil fuels for energy, including finite supply, energy security and their contribution to rising atmospheric CO2 concentrations and climate change, leading to substantial, increased interest in the research and development of renewable energy. In 2006, renewable energy provided only 2.5% of global energy needs, which is well short of the national renewable energy targets of many countries for the period 2020-2030, including Australia. For these reasons there is substantial investment in the development of renewable fuel technologies. Bioethanol and biodiesel derived from biomass are alternative fuels for which production capacity and demand is rapidly increasing.

The Atlantic and Pacific coasts of Mexico offer a variety of marine energy sources for exploitation. Although the Mexican government has made important efforts to reduce its dependence on fossil fuels, national participation in clean energies is still limited in terms of electricity production. This paper presents a practical theoretical assessment of marine energy sources around Mexico, with the aim of identifying potential zones for subsequent, more detailed, technical evaluations and project implementations. The energy sources considered are ocean currents, waves, salinity, and thermal gradients. Using global databases, the percentages of energy availability for the defined thresholds were computed to establish the prospective regions with the most persistent power availability. This approach proved to offer more meaningful information than simple averaged values. Moreover, some environmental and socio-economic factors to be considered for future ocean energy resource assessments in Mexico were also discussed. The results show that the wave energy potential is highest in the northwest of Mexico (~2–10 kW/m for more than 50% of the time), and that there is a constant source of ocean current energy off Quintana Roo state (~32–215 W/m2 for more than 50% of the time). The thermal gradient power is more persistent in the southwest and southeast of the country, where ~100–200 MW can be found 70% of the time. The salinity gradient energy is strongest in the southeast of Mexico. The practical approach presented here can be extended to perform preliminary resources assessments in regions where information is scarce.

The lauded Renewable Energy Independent Power Producer Procurement Program (REIPPPP) has achieved much in stimulating private sector investment in the renewable energy market in South Africa. Yet, 95% of electricity generated is still from a single source, the state-owned utility Eskom. This paper set out to explore the policy sphere governing electricity generation and identifying possible avenues that can contribute to a more vibrant solar energy market in the most solar abundant province of South Africa, the Northern Cape Province. Licensed mines were identified as low hanging fruit due to a large policy overlap and leeway within existing mining policy. A solar audit of these areas was performed, based on accepted multi-criteria decision analysis techniques, and found that a potential 369 TWh to 679 TWh per annum can be generated, exceeding South Africa’s current electricity usage.

Carbon Dependency

With the effects of climate change linked to the use of fossil fuels, as well as the prospect of their eventual depletion, becoming more noticeable, political establishment and society appear ready to switch towards using renewable energy. Solar power and wind power are considered to be the most significant source of global low-carbon energy supply. Wind energy continues to expand as it becomes cheaper and more technologically advanced. Yet, despite these expectations and developments, fossil fuels still comprise nine-tenths of the global commercial energy supply. In this article, the history, technology, and politics involved in the production and barriers to acceptance of wind energy will be explored. The central question is why, despite the problems associated with the use of fossil fuels, carbon dependency has not yet given way to the more ecologically benign forms of energy. Having briefly surveyed some literature on the role of political and corporate stakeholders, as well as theories relating to sociological and psychological factors responsible for the grassroots’ resistance (“not in my backyard” or NIMBYs) to renewable energy, the findings indicate that motivation for opposition to wind power varies. While the grassroots resistance is often fueled by the mistrust of the government, the governments’ reason for resisting renewable energy can be explained by their history of a close relationship with the industrial partners. This article develops an argument that understanding of various motivations for resistance at different stakeholder levels opens up space for better strategies for a successful energy transition.

Photovoltaics (PV-also called solar photovoltaic devices) are used to harness the power of the sun via the electronic process that occurs within semiconductor cells. The solar energy is absorbed by the cells, which causes the electrons to break away from their atoms, allowing them to flow within the material to produce electricity. This electricity will become the renewable energy for Kentucky, as the generation of coal will but come to a stop within the near future. Like Denmark who is running on 100% renewable generation we must stride to become fully operational on solar. In the present work, we systematically studied about renewable energy resources, in particular, solar energy for the application of photovoltaic panels in Eastern Kentucky. By analyzing data from our PV cells at Morehead State University designed to follow the direction of the sun for optimized output and by incorporating MPPT charge controllers, we have constructed a maximum power algorithm that performs best for the location. Utilizing these, measurements of daily electricity production in comparison to the average power needed for household use has validated our research. With the advancements in solar cell technology what was once impossible is now reality, as solar power can easily power this region based on our data. Knowing this, being a prime location we can now push to enable the advancement of renewable energy production and become less dependent on fossil fuels, thus creating an infrastructure that will run off solar power.
