<p>Las energías renovables son indispensables para que un proceso productivo incremente su eficiencia, mejore su desempeño ambiental y fortalezca su ventaja competitiva en la medida en que su uso sirve para disminuir las emisiones atmosféricas y por lo tanto aporta a la mitigacion del cambio climático. Existe una aproximación de los empresarios al uso de las energías renovables motivada por razones inminentemente prácticas, algunas veces porque sus clientes lo exigen desde certificaciones verdes o de responsabilidad ambiental, otras porque las autoridades ambientales lo requieren y muchas veces porque los sistemas de provision de energia que tienen son muy costosos. Cuando los empresarios o algún funcionario busca implementar las energias renovables se encuentran con una cantidad de obstáculos e incertidumbres mientras que desde diferentes áreas del conocimiento se tienen una serie de herramientas probadas que sirven, al integrarlas, para incrementar la eficacia en el propósito de implementar esas energías.Se presenta en este documento en primer lugar la metodologia del ciclo de vida enmarcada en el enfoque sistemico de las organizaciones, en segundo lugar varias herramientas que permiten manegar el talento humano para que acepten autónomamente ese mejoramiento tecnológico que son las energías renovables y en tercer lugar, se muestran las ventajas que tiene ese manejo sistémico de la organización en la mitigación del cambio climático con el uso de las energias renovables.</p><p class="Pa4"><strong>Abstract </strong></p><p>Renewable energies are essential for a cleaner productive process. These energies improve efficiency, environmental performance and strengthen the competitive advantage of companies. Furthermore, this type of energies reduce air emissions and therefore contributes to the mitigation of climate change. Entrepreneurs implement renewable energy mainly influenced and pressed by external practical reasons. For example, sometimes customers demand from them green certifications or environmental responsibility in operations; in others cases, environmental authorities require reduction of emissions and often, manangers realizes that conventional energy supply systems are very expensive or not safe. Emplo­yees and officers have at their disposition different proven tools that are provided by many areas of knowledge. The integrated application of these tools permits to overcome obstacles and uncertainties encountered in the implementation of renewable energies systems in the company. This document provides three tools that are useful to managers to apply renewable energy systems as follows: 1) The methodology life cycle framed in the systemic approach of organizations, 2) several tools to manage human talent to accept autonomously that technological improvements which are renewable energy and 3) the advan­tages of the systemic management of the organization. With the integrated implementation of these tools the paper shows that renewable energys are key to mitigate climate change.</p>

Change Mitigation

Evidence shows that global climate change is increasing over time, and requires the adoption of a variety of coping methods. As an alternative for conventional electricity systems, renewable energies are considered to be an important policy tool for reducing greenhouse gas emissions, and therefore, they play an important role in climate change mitigation strategies. Renewable energies, however, may also play a crucial role in climate change adaptation strategies because they can reduce the vulnerability of energy systems to extreme events. The paper examines whether policy-makers in Israel tend to focus on mitigation strategies or on adaptation strategies in renewable energy policy discourse. The results indicate that despite Israel’s minor impact on global greenhouse gas emissions, policy-makers focus more on promoting renewable energies as a climate change mitigation strategy rather than an adaptation strategy. These findings shed light on the important role of international influence—which tends to emphasize mitigation over adaptation—in motivating the domestic policy discourse on renewable energy as a coping method with climate change.

The majority of the single-family houses in Sweden are affected by deteriorations in building envelopes as well as heating, ventilation and air conditioning systems. These dwellings are, therefore, in need of extensive renovation, which provides an excellent opportunity to install renewable energy supply systems to reduce the total energy consumption. The high investment costs of the renewable energy supply systems were previously distinguished as the main barrier in the installation of these systems in Sweden. House-owners should, therefore, compare the profitability of the energy supply systems and select the one, which will allow them to reduce their operational costs. This study analyses the profitability of a ground source heat pump, photovoltaic solar panels and an integrated ground source heat pump with a photovoltaic system, as three energy supply systems for a single-family house in Sweden. The profitability of the supply systems was analysed by calculating the payback period (PBP) and internal rate of return (IRR) for these systems. Three different energy prices, three different interest rates, and two different lifespans were considered when calculating the IRR and PBP. In addition, the profitability of the supply systems was analysed for four Swedish climate zones. The analyses of results show that the ground source heat pump system was the most profitable energy supply system since it provided a short PBP and high IRR in all climate zones when compared with the other energy supply systems. Additionally, results show that increasing the energy price improved the profitability of the supply systems in all climate zones.

Energy Supply Systems

Currently, the majority of world economies (even those located in the sunbelt (+/− 35 degrees of latitude with good sunshine with low seasonality) uses various types of fossil fuels as the main source of energy for their economies. However, this represents a very volatile and unsustainable strategy, since according to various estimates, the fossil fuel era will inevitably end as all carbon fuels are going to be spent in the next few centuries. Unlike traditional energy, renewable energy sources (RES) are not based on energy resources, but rather rely upon natural energy flows. With regard to its unique property, there has been an active construction of power plants of renewable energy and their gradual integration into national energy supply systems in recent decades. At the same time, the existing models of electricity markets were unprepared for their wide distribution. Hence, determination of the market value of energy generated by power plants using renewable energy sources becomes a particularly significant issue. This market value has to take into account the prevention of costs from the use of fossil fuels, as well as the resulting environmental benefits. Our paper proposes methods for solving this problem, contributing to the increase of economic efficiency of investment projects for the construction of renewable energy facilities and the formation of economic incentives for their propagation in energy supply systems. The proposed methods are based on the dynamic differentiation of tariffs for consumers with renewable energy sources depending on their structure of electricity consumption. Its effectiveness is demonstrated by calculating the cost of electricity for households located in the Krasnodar region using renewable energy sources. It is shown that this approach to the formation of tariffs for consumers allows the household to receive additional savings from the efficient use of energy installations on RES and energy storage devices in terms of alignment of the energy consumption schedule. This creates a significant incentive for households to use them and contributes to increasing the effectiveness of government renewable energy support programs, including by solving the acute problem of raising electricity tariffs from the grid.

Adaptation And Mitigation

AbstractThis article examines the role human rights instruments play when states seek to adopt regulatory initiatives in the name of addressing climate change. The article argues that a series of important restrictions exist. Governments responding to climate change need to take into account existing human rights. This observation is particularly relevant for countries implementing Reduction of Emissions from Deforestation and Degradation (REDD) projects and for countries taking part in Clean Development Mechanism (CDM) projects under the Kyoto Protocol. The article likewise argues that special human rights obligations arise in relation to the risks associated with climate change. These place on states a responsibility to secure risk assessment and risk communication while taking steps to mitigate climate change-associated risks. While the article considers these requirements to constitute an absolute minimum, it is argued that they can offer a way of securing that national governments are accountable when it comes to climate change responses. On the other hand, it will be shown that these human rights restrictions will sometimes have the potential to run counter to the adoption of effective climate change responses.
