<a name="OLE_LINK28"></a><a name="OLE_LINK27"></a><span>Electrical energy is important in various developments to ensure global stability. However, most electrical energy sources are non-renewable and these sources are expected to be depleted in the near future. In order to solve this problem, research on renewable energy sources are intensified and thermoelectric generator (TEG) is one of the potential solutions. TEG can generate electricity if the there is a temperature difference between the hot end and cold end of its plate and it is widely used in various applications, ranging from high temperature of a steam generator until to the lowest temperature of a human body. The initial development of this work focuses on the electrical power generator design by using focal lens to focus sunlight, a form of renewable energy, on the TEG hot end and also underground heat dissipation system on the cold end to create temperature difference. The initial results showed that the amount of power produced by the system is quite small but reasonable due to the type of TEGs used. However, the heat dissipation system showed a promising development due to its non-dependency on external energy to expel heat from the cold side</span><span>.</span>

Towards the end of the previous century, the humanity understood very clearly two facts – first, the World supplies of fossil fuels (coal, oil, gas, uranium) are limited, and, second, industrial development and classical generation of electrical energy seriously endanger the environment. Renewable energy sources (sun energy, wind energy, bio fuels, etc.) are based on the use of natural fluxes of energy (Masters,2004). That is why they are considered to be inexhaustible. In specific cases of implementations, for example in lighting, a direct generation of electrical energy using photovoltaics is outlined as a long-term one.

The Waves

The need for electrical energy has increased every year. On the other hand, the largest power plants in Indonesia still use non-renewable energy sources such as coal and petroleum, while these non-renewable energy sources will eventually run out. To anticipate running out of this energy, a renewable energy source is needed. This existence will not run out even though it is consumed every day. Renewable energy that can be used for conversion into electrical energy in coastal areas is wave power.  The waves that always crash on the shoreline can be used to drive turbines. The turbine rotates due to the crashing waves connected to a DC generator. It will convert mechanical energy into electrical energy. The electrical energy generated by the DC generator is used to charge the battery. The purpose of this research is the know-how to design a wave power generator and to determine the performance. The experimental method is used in this study. In the results, the generator works optimally during the day with the resulting voltage of 10.6 V to 10.7 V with rotation speed of 623 Rpm to With 710 Rpm.

Electrolysis Method

Electrical energy is one of the primer facilities used in every activity. Almost all the existing facilities use electricity. This is inversely proportional to the depleting energy source. The solution to this problem is to replace fossil fuels with renewable energy sources. Renewable energy is a source of energy that can be recycled and does not damage the environment. One type of renewable energy is to use the electrolysis method. Electrolysis Method is one of the renewable energy sources. This method uses electrolyte solution which can be found in sour and runny fruit such as lemon (Citrus Limon L.) and Wuluh Star fruit (Averrhoa bilimbi). The study was conducted in a laboratory by mixing the results of the juice of the two fruits with different compositions. The mixes are placed in the arcs (a mixture container to test the electrical properties) and then tested using a multimeter every 2 hours for 24 hours. The results are described in graphical form. The average power of each mixture is, C1 = 2.2mW, C2 = 4.7mW, and C3 = 8.5 mW and based on the graph, each mixture has decreased voltage and current. Even so among the three mixtures, the third mixture has a better electrical power value than the other two mixes. This shows that the higher the acidity of a solution the higher the electricity produced.

Thermal Power Plants

It is well known that the electrical-power generation is the key factor for advances in any other industries, agriculture and level of living. In general, electrical energy can be generated by: 1) non-renewable-energy sources such as coal, natural gas, oil, and nuclear; and 2) renewable-energy sources such as hydro, wind, solar, biomass, geothermal and marine. However, the main sources for electrical-energy generation are: 1) thermal - primary coal and secondary natural gas; 2) “large” hydro and 3) nuclear. The rest of the energy sources might have visible impact just in some countries. Modern advanced thermal power plants have reached very high thermal efficiencies (55–62%). In spite of that they are still the largest emitters of carbon dioxide into atmosphere. Due to that, reliable non-fossil-fuel energy generation, such as nuclear power, becomes more and more attractive. However, current Nuclear Power Plants (NPPs) are way behind by thermal efficiency (30–42%) compared to that of advanced thermal power plants. Therefore, it is important to consider various ways to enhance thermal efficiency of NPPs. The paper presents comparison of thermodynamic cycles and layouts of modern NPPs and discusses ways to improve their thermal efficiencies.

The Future

The goal of power sector in Nigeria is to efficiently and reliably transmit electrical power to all parts of the country which are made up of thirty-six states of the federation and the federal capital territory. The constituents of electrical power system are the generation, transmission, distribution and the utilization of electrical energy. There is gross power imbalance between the generation and the required power demand which has culminated into a defective economy in the last three decades. This paper therefore examines the power imbalance between the generation and power demand by the consumers and therefore stresses the need to harness the opportunity of renewable energy generation close to the gap between the power generation and power demand. This will help in transmitting and distributing efficient, effective, reliable power to consumers and improve both human and capital development. The availability of renewable energy sources such as sun, wind and small hydro power will be explored for the future of power generation in the country to fill in the gap between power generation and demand in Nigeria
