Pollution and climate change due to the use of fossil fuel can no longer be denied, and this coupled with a waning supply of oil leads one to inevitably conclude that a clean, sustainable energy source is needed. That source is solar energy, the cleanest, safest, and most environmentally friendly energy source we have. In this paper, a photovoltaic (PV) solar energy system is used to generate electricity that will recharge a battery (DC 12V). The portable recharged battery will serve as the energy source for an electric vehicle. Moreover, in order to reduce manpower, a PC-based remote electrical monitoring technique used in the battery’s recharged system will be established via a TCP/IP network. Consequently, a PV solar panel with a 30 Watt capacity used to generate electricity using a PC-based monitoring system is exemplified.

Energy in developing countries essential for economic growth and development. In result of the rapid growth of development, society demands more electricity. In addition to that, unsustainable energy production can have a harmful effect on our environment. Solar energy is the most inexhaustible method of energy. With that has been stated, it is evident that PV technology is starting to be one of the primary roots of energy generator to supply power for development. The economic ambition is to create solar energy more cost effective and efficient, nevertheless, it is still not compatible with fossil fuel. Typically, in order for solar energy to replace the fossil fuel or at least support the development demands of energy, the implementation of solar energy system must increase in homes and plantation projects. This problem drove governments to come up with policies that encourage implementing solar system in homes of citizens. The most used policies are fed in tariff and net energy metering, which is applied in 80 nations round the globe. This paper studied the policies applied in solar energy in Malaysia in the past 8 years. The paper went over each policy and considered their financial and environmental welfare. It did show the effect of the policy applied at the time on the capacity installed in Malaysia.

Climate change can affect the level and type of demand for electricity for development service delivery. Extreme events associated with climate change can disrupt the existing electricity supply, leading to demand for alternate or backup electricity sources. Communities rely on electrically powered activities to respond to conditions caused or exacerbated by climate change. Finally, electricity is required for ongoing activities that can potentially build long-term capacities to cope with climate-related events. Effective decentralized solar solutions in climate vulnerable regions must be tailored to local conditions. Energy systems must be designed to meet context-specific electricity demand, based on local geography, the availability of supportive infrastructure, and end-use requirements. For example, planning for the design, installation, and maintenance of a decentralized solar energy system in a flood-prone char island school is very different from that in a lightning-prone mainland school, even if both schools fall under the same government program. Decentralized solar energy systems are not entirely climate proof. Components of decentralized solar solutions are vulnerable to climate-related events such as floods, lightning, extreme temperature, and rainfall. Understanding and planning for the climate risks in advance can help reduce downtime, loss of assets, and build resilience. Resilience planning starts before the design stage and continues thereafter. Project implementers, policymakers, and donors need to realize that building resilient structures and communities begins well before the design stage. System design and operation and maintenance planning should be based on climate-risk data and models, local socioeconomic and ecosystem assessments, policies, and design standards that promote and enforce resilient infrastructure and support community resilience. Technology is just one component of a climate resilient decentralized solar installation. Organizational arrangements need to incorporate climate considerations while setting expectations and assigning roles and responsibilities. Climate resilient design needs to also translate into the funding plan, with innovative financing and risk hedging models. There is a need to go beyond conventional implementation models. Traditional implementation models have specific, often siloed responsibilities. The uncertainty created by climate change requires all stakeholders to be more flexible and responsive and demands more innovative implementation, operation, and maintenance models. Examples include energy and development partners working together from the start, active participation and capacity building of end users and community members, and innovative financing models.

Concentrated Solar Power

The Chilean Energy Policy calls for 15 percent of new power generation capacity to come from renewable energy sources from 2006 to 2010, and then a 5% of electric energy generated from renewable energy sources with gradual increases in order to reach 10% by 2024. Neither the government nor the power generation sector plans mention solar energy to be part of the renewable energy initiative. Part of this apparent lack of interest in solar energy might be due to the absence of a valid solar energy database, adequate for energy system planning activities. Monthly means of solar radiation are used in order to estimate the solar fraction for a 100 MW plant for four given locations. Our analysis considers two cases: operation during sunlight hours, and continuous operation during 24 hours a day. A net energy analysis for concentrated solar power (CSP) plants in Chile is then performed, considering the energy costs of manufacturing, transport, installation, operation and decommissioning. The results indicate that the CSP plants are a net energy source in three of the four locations, when operating in sunlight-only mode. This is due to the lower radiation levels available at that location, which implies a high fossil fuel back-up fraction. In the continuous operation mode, the CSP plants become fossil fuel plants with solar assistance, and therefore all locations display negative net energy. Based on this result, the back-up fraction required for the plants to be net energy sources is estimated from the EROEI as function of the back-up fraction. It is estimated that the net energy analysis is a useful tool for determining under which conditions a CSP plant becomes a net energy source, and thus can be utilized in order to define geographical locations and operation conditions where they can be considered renewable energy sources.

Effective Use

It is general that each of the heat and electricity is individually supplied even if their resources are the same. However, from the viewpoint of the effective use of energy resources, development of co-generation producing both of them is promoted. To enhance more the utilization of energy resources, it is considered to supply three different types of energy from one energy resource. This is a basic concept of tri-generation and we named it first in the world. Tri-generation we proposed supplies heat, electricity and fuel. By this definition, we can easily understand that tri-generation is realized by utilizing solar energy. Therefore, we call it solar tri-generation. In this paper, the methods of system structure and the feature of solar tri-generation are described and we conducted a simplified analysis to make clear the effectiveness of solar tri-generation in the comparison of effective use of solar energy with a solar co-generation consisting of photovoltaic cell modules and photovoltaic/thermal modules. Furthermore, from the viewpoint of CO2 emission reduction, we conducted a simplified analysis to make clear the characteristics of energy consumption in the three systems of a fossil fuel fired co-generation and, a solar co-generation and a tri-generation with fossil fuel fired co-generation.

The Future

The majority of Niger’s population faces a widespread lack of access to electricity. Although the country lies in the Sahara belt, exploitation of solar energy is so far minimal. Due to ongoing fossil fuel exploration in the country, this fuel might dominate the future electricity supply. Today, Niger imports the most of its electricity from Nigeria. There is a need to expand electricity generation and supply infrastructures in Niger. When doing so, it is important to choose a proper set of electricity generation resource/technology that fulfils sustainability criteria. Thus, the objective of this work is to analyze a methodology in order to assess different energy technologies for Niger. A multi-criteria decision approach was selected to assess the most accessible energy system for the country. For this purpose, indicators were developed and weighted for ranking electricity generation options. Altogether 40 indicators are selected under six dimensions (availability, risk, technology, economics, environment and social) to assess eight different alternatives, considering the aggregated results and corresponding scores under each dimension. A merit list of technology and resources for electricity generation presented in this work could support the stakeholders in their decision-making for further projects implementation in the country.

Testing Procedures

Methane is the second strongest greenhouse gas contributing to climate change after carbon dioxide. Reducing methane emissions contributes to both slowing climate change and improving air quality. In order to reduce methane emissions from the energy sector, the European Commission has proposed the obligation to improve leak detection and disposal in fossil fuel infrastructure, as well as any other infrastructure that produces, transports or uses fossil fuels. Compressors and compressor stations are such a component of the energy system. The paper presents the testing procedures of the valves in the gas transmission pipes for the evaluation of external leaks and the proposed corrective actions to minimize them.
