Starting Point

The aim of the manuscript was to present the collective results of research on the profitability of using various renewable sources in Poland with the greatest development potential. In the paper, the economic parameters of various investment projects were determined and calculated, i.e., Net Capital Value (NPV), Internal Rate of Return (IRR) and the Period of Return on Invested Capital (PBT). The economic assessment of the use of RES technologies was supplemented with the assessment of environmental benefits. The ecological criterion adopted in the study was the assessment of the potential and costs of reducing greenhouse gas emissions as a result of replacing fossil fuels with renewable energy technologies. On the basis of the constructed economic model to assess the profitability of investments, it has been shown that the analyzed projects will start to bring, depending on their type and technical specification, measurable economic benefits in the form of a reduction in the amount of energy purchased on an annual basis and environmental benefits in the form of reduction of carbon dioxide emissions to the atmosphere. Moreover, the calculations show a high potential for the use of certain renewable sources in Poland, which contributes to the fulfillment of energy and emission obligations towards the EU. The analyzes and research of the Polish energy market with the use of the presented models have shown that the project is fully economically justified and will allow investors to make a rational decision on the appropriate selection of a specific renewable energy source for their investment. The presented economic models to assess the profitability of investments in renewable energy sources can be successfully used in other countries and can also be a starting point for a discussion about the direction of energy development. Due to the lack of collective, original and up-to-date research on the domestic market, the manuscript provides the reader with the necessary knowledge regarding the legitimacy of using renewable energy sources, investment and environmental profitability.

The Impact

Background: The growing consumption is what drives the development of unsustainable energy and material-intensive production technologies that emit large quantities of pollutants into the atmosphere, water, and land. Obtaining green energy allows reduction of the interference with the environment and, consequently, fits into a sustainable energy development strategy. In order to achieve the emission targets set by the EU for Poland, it is necessary to prioritize the development of renewable energy sources (RES) technologies within the energy sector.Methods: The purpose of the study was to present the results of the research relating to the return on investment of solar collectors for single-family houses in Poland. The research was presented on the basis of the legal conditions applicable to micro installations in the light of the amendment of the RES Act, and the impact of these amendments on the aspects of such investment was determined.Results: On the basis of the constructed economic model used to assess the return on investment of increasing the area of solar collectors, it has been shown that an operating installation will bring measurable economic benefits in the form of reduction in the amount of energy purchased annually in the amount of 6,756 kWh and environmental benefits in the form of reduction of carbon dioxide emissions to the atmosphere 2.4–3.6 Mg per year. An installation subsidized under the “My Electricity” program can reach an NPV of EUR 6,000 over 20 years at a discount rate r = 0 and assuming that the electricity is EUR 0.15/kWh. If the price rises to 0.2 EUR/kWh, the NPV will be 10,000 EUR. For the analyzed installation, the investment consisting in increasing the collector area in accordance with NPV is economically effective for the absorber area in the range of 5.6–7.6 m2 and reaches the maximum value for the absorber area of 6.6 m2, while the absorber area above 7 m2 contributes to reduce the value of the economic return on investment. The obtained results have been generalized, which allows to use them in the process of selecting the size of collector area for similar installations.Conclusion: The return on investment analysis carried out in respect of a detached house allowed to demonstrate that this project is fully justified. Furthermore, pursuant to the Renewable Energy Sources Act in force in Poland, treating a small entrepreneur as a prosumer who may generally take advantage of favorable conditions for discounting the produced energy leads to very favorable possibilities of settling electricity. Considering an entrepreneur as a prosumer who may use one-off depreciation of a solar collectors installation as a fixed asset and request for VAT refund is what makes such an investment very attractive in financial terms and makes it difficult to find a safe investment alternative characterized by such a high rate of return.

Electricity Infrastructure

The electricity grid in the United States may be the largest, most pervasive technological system ever constructed to meet the needs and comforts of human beings (Nye 1997). Although it is less than 150 years old, the electricity infrastructure of this nation is ubiquitous; power lines stretch across deserts, forests, states, highways, and the entire nation in order to provide electricity to residences, businesses, and communities. The electricity carried by these transmission lines is generally produced using fossil fuels (mostly coal; see US Energy Information Administration 2012) and is most commonly generated at a monstrously large facility (a coal plant, a nuclear facility, or a hydropower dam). Our electricity infrastructure was constructed to carry enormous amounts of electricity across vast geographical expanses, based on the massive generation facilities and concentrated fossil fuel based energy sources that defined the system and its use. However, there are increasing concerns regarding the sources of our energy supply. Many of these concerns are related to climate change and how carbon dioxide emissions from burning fossil fuels contribute to rising global temperatures and the climate instability of the planet (Brown 2003). Additional concerns include the host of other environmental damages caused by the use of coal (Epstein et al. 2011), nuclear energy (Slovic et al. 1991), and hydro-electricity (Dincer 1998); other debates involve worries about nearing or reaching peak energy supplies (Brown 2003), energy security (Yergin 2006), and the aging transmission grid (Amin 2003). For a multitude of reasons, many would agree that it’s time to rethink our dependence on fossil fuel based forms of energy and move toward alternative, renewable energy sources (Brown 2003, pp. 116–135). The good news is, the renewable energy industry gets bigger every year, with more energy from renewable sources being produced, sold, and used (Sherwood 2011). Some US states have enacted renewable energy standards requiring that a certain percentage of their electricity supply come from renewable sources. Tax incentives, subsidies, and various forms of rebates, in financially incentivizing renewable energy adoption, also provide evidence that we are indeed moving in the direction of clean, renewable sources of energy.

Developing Area

Renewable energy is a rapidly developing area of the modern economy. As many experts forecast, global electricity consumption will double by 2050, while the share of renewable sources in energy generation will be 50%. For most states, the main incentives for the development of renewable energy are the ability to eliminate the consumption of fossil fuels and reduce the level of emissions of pollutants, while ensuring sustainable development of the country. At the same time, Russia, which has significant reserves of natural resources, is in no hurry to switch to the use of energy from renewable sources since it is believed that the country’s subsoil can provide it with cheap energy resources for many generations to come. Therefore, introduction of renewable energy sources that are unable to compete with traditional energy without a developed energy infrastructure and established production is impractical. In our study we try to evaluate the efficiency of the introduction of renewable energy sources in the Krasnoyarsk Territory of Russia using the example of the Chinese experience.

Energy Companies

A large number of energy companies in the world today a faced with global transformative trends which devastatingly affect their business results. Therefore, energy companies in the world were very slow in investing and adopting renewable energy sources and become significantly overcapacitated by coal and gas fired power plants which are now unprofitabile due to low marginal costs of renewables and their priority dispatching into a power system. Also increasing the share of renewable energy sources in the structure of electricity generation, the decline in primary energy prices (fossil fuels) the stagnation of consuption and the surplus of supply in relation to electricity demand caused a drop in wholesale electricity prices by half compared to 2008. Furthemore, the operation of coal fired power plants is burdened with carbon dioxide emissions. As a result, there has been a significant reduction in revenues, falling stock values andthe collapse of credit rating of many energy companies in the world. This article analyzes the implementation of the strategy of empowering customers and shaping markets that the E.ON Group has carried out as a „response“ to global transformative trends in the energy market environment by which the former company was divided into two less dynamic and more focused companies into a new or conventional energy world. This strengthens the competitiveness of all previous business activities due to stronger focus on the development of necessary skills and process. Furthemore, from on investor perspective it has been shown that the risk profiles associated with conventional energy production differ from those related to the „new“ energy world, ie the activities covered by the business portfolio of the E.ON Group, and the activities covered by the business portfolio of the Uniper Group attract different types of investors.

Renewable energy is considered an infinite source of energy. Although they have unlimited potential towards making our environment self-sustainable, they are currently insufficiently exploited and unevenly distributed. The major hindrance to exploiting these renewable sources is economic issues. Some countries, that possess these sources are currently developing or are still in the under-developed scenario. Hence, these resources are not being exploited to their full potential. We are aware of the severe consequences of burning up fossil fuels and their adverse effect on our environment Rarely do we think of the consequences on the environment due to renewable energy sources. Although they have a very small impact on our environment, in the future it might lead to some devastating issues. Some of the renewable energy sources have a visual impact on the nature of our earth and also to some extent it can affect the ecosystem of a particular area. This paper intends to analyze the current types of renewable sources (solar, wind, geothermal and hydroelectric) and their impact on our planet.

Renewable technologies are technically viable and economically attractive; traditional energy technology receives many investment dollars. This study examines the integration of renewable energy sources using functions that associate emissions with power generation; traditional producing units can represent these emissions. The environment friendly design has become a significant concern in the first decade of the 21st century. As a result of climate change and a limited supply of traditional energy sources (fossil fuel), the world needs to take renewable energy seriously. Renewable sources of energy are derived from the energy flow that occurs naturally in a continual manner. Many people define renewability as the ability to regenerate at a rate equal to or faster than a given energy source's depletion rate. Currently, fossil fuels are used to meet most energy needs, which should be replaced in the future by cleaner energy sources, such as renewables or nuclear energy. Building integration systems aim to replace a building element with a solar panel array to boost the RES system's viability. Renewable energy sources can be used to lessen the use of fossil fuels when certain criteria are satisfied. The use of renewable energy sources in buildings has well-understood environmental and economic benefits in this study. By relying on sustainable sources of energy, we can save as much energy as feasible.

Oil Sector

Fossil fuels have been the mainstream of energy supply and a major source of foreign exchange earnings for the Federal Government of Nigeria, in spite of being an unrenewable and unsustainable source of energy. Nigeria is yet to tap into the full benefits after privatising its power sector, including the new global evolution in the energy sector and the resulting increasing demand for renewable energy sources, which some consider to be cheaper and more environmentally friendly than fossil fuels and their allied products. Energy security is a challenge to socio-economic development in Nigeria, due to the country’s over-dependency on fossil fuels. In terms of their impact and the potentials to preserve energy sources for longevity and sustainability, however, fossil fuels will come to be seen as an out-dated alternative in the power sector as the energy industry evolves. The implications for Nigeria’s oil sector will not be limited to dwindling crude oil prices. The concerns include poor energy utilisation in Nigeria and the need to promote energy efficiency and sustainability. They have led to the formulation of new energy policies around the world to serve as a vehicle for translating solutions into reality. This study has adopted a library-based legal research method with a comparative approach. The study reveals that it is the lack of a coherent legal framework with incentives for using renewable energy that is largely seen as the key issue causing slow uptake of renewable energy as an alternative source of energy in Nigeria. As well as the need for a coherent legal framework on energy and incentives for using renewable energy sources, the study advocates stringent enforcement of existing energy regulatory policies.
