As the energy demand of the world is rising, more and more efforts are being made to harness different forms of energy available. Current pollution due to fossil fuels has directed the world to shift to cleaner renewable energies, such as solar. Photovoltaic, as well as concentrated solar technologies, are developed to harness solar energy. The concentrated solar tower power plant is an emerging technology and is under development having vast areas of improvement. The efficiency of the concentrated solar tower power plant depends upon the accuracy of the tracking system of the heliostats placed all around the central tower of the plant. A closed-loop tracking system a feedback method is a need. In addition, to check the accuracy of the system, a calibration system is required. This system uses different types of sensors. In this study, an effort is made to enlist different types of sensors available and their use in the tracking system of the solar thermal tower power plant. In addition, different sensors are suggested that are best suited for calibration and correction purposes.

As society develops, the demand for energy also increases. Most of world's energy requirements are fulfilled using fossil fuels or other types of non-renewable resources, which are polluting the environment, but also depleting. For this reason, the Government of India and the Government of Sikkim (North Eastern State of India) are working on policies to promote investment in solar photovoltaic (PV) plants and has plans to use it to meet the growing energy demand without causing damage to the environment. To make the best use of solar PV cells on commercial scale, it is necessary to know how to optimize the output of the PV power plant, and the most important factor is the selection of the land or the area on which the PV power plant is to be set up. There are multiple factors one must take into consideration for better output. In this study, focus has been put on geographical and meteorological factors that affect the output of the PV cells. Multi criteria decision making (MCDM) techniques have been used for selection of best site for PV power plant.

The limited fossil reserves, spiraling price and environmental impact due to usage of fossil fuels leads the world wide researchers’ interest in using alternative renewable and environment safe fuels that can meet the energy demand. Biodiesel is an emerging renewable alternative fuel to conventional diesel which can be produced from both edible and non-edible oils, animal fats, algae etc. The society is in dire need of using renewable fuels as an immediate control measure to mitigate the pollution level. In this work an attempt is made to review the requisite and access the capability of the biodiesel in improving the environmental degradation.

Mitigation of global warming requires an understanding of where energy is produced and consumed, the magnitude of carbon dioxide generation, and proper understanding of the Carbon Cycle. The latter leads to the distinction between and need for both CO2 and biomass CARBON sequestration. Short reviews are provided for prior technologies proposed for reducing CO2 emissions from fossil fuels or substituting renewable energy, focusing on their limitations. None offer a complete solution. Of these, CO2 sequestration is poised to have the largest impact. We know how to do it. It will just cost money, and scale-up is a huge challenge. Few projects have been brought forward to semi-commercial scale. Transportation accounts for only about 30% of U.S. overall energy demand. Biofuels penetration remains small, and thus, they contribute a trivial amount of overall CO2 reduction, even though 40% of U.S. corn and 30% of soybeans are devoted to their production. Bioethanol is traced through its Carbon Cycle and shown to be both energy inefficient, and an inefficient use of biomass carbon. Both biofuels and CO2 sequestration reduce FUTURE CO2 emissions from continued use of fossil fuels. They will not remove CO2 ALREADY in the atmosphere. The only way to do that is to break the Carbon Cycle by growing biomass from atmospheric CO2 and sequestering biomass CARBON. Theoretically, sequestration of only a fraction of the world’s tree leaves, which are renewed every year, can get the world to Net Zero CO2 without disturbing the underlying forests.

As the world population and modernization increase, energy demand increases. One of the non-sustainable energy sources is fossil fuels. However, fossil fuel consumption raises various environmental and economic issues. Most of the studies focus on sustainable energy sources, which can replace fossil fuel dependence. Biodiesel is an alternative sustainable fuel for diesel power. Biodiesel can produce through the transesterification process. Since the catalyst plays a significant role in the biodiesel yield during a defined reaction time, the addition of a catalyst can increases the reaction rate. This article is outlined the several catalysts used by multiple researchers over the years to increase biodiesel yields.

The proper utilization of all the available forms of energy resources has become imminent to meet the power requirement and energy demand in both the developed and developing countries of the world. Even though the emphasis is given to the renewable resources in most parts of the world, but fossil fuels will still remain the main resources of energy as these can meet both normal and peak demands. Saudi Arab has number of power plant based on natural gas and fuel that are spread in all its regions. These power plants have aeroderivative gas turbine units supplied by General Electric Company as main power producing units. These units work on dual fuel systems. These units work as simple gas turbine units to meat peak demands and as part of combined cycle otherwise. The subject matter of this study is the performance of one of the units of a power plant situated near Riyadh city of Saudi Arab. This unit also works both as simple gas turbine unit and as a part of combined cycle power plant unit. A parametric based performance evaluation of the unit has been carried out to study both energetic and exergetic performance of the unit for both simple and combined cycle operation. Effect of compressor inlet temperature, turbine inlet temperature, pressure ratio of the compressor, the stage from which bleed off air have been taken and percentage of bleed off air from the compressor on the energetic and exergetic performance of the unit have been studied. The study reveals that all these parameters effect the performance of the unit in both modes of operation.

The world needs an alternative fuels that could maintain the world running on its wheels due to the increasing energy demand and uncertainty in availability of the fossil fuels. The present investigation analyzes the scope of utilizing the Deccan hemp oil based biodiesel derived from jute seed as an alternative to the diesel. Experimental investigation was carried out at diesel engine with different loads from 0% to 100% and 10% overload condition under a constant speed of 1500 rpm. It was found that the reduction in brake thermal efficiency and higher brake specific fuel consumption was observed with biodiesel in comparison with diesel. The carbon monoxide (CO), carbon-dioxide (CO2), unburnt hydrocarbon (HC) and nitric oxide (NO) emissions for Deccan hemp oil based biodiesel were reduced by 0.2% vol, 1.6% vol, 62.5%, 36.84% whereas slightly higher smoke emission was observed when compared to diesel fuel. These studies revealed that Deccan hemp oil based biodiesel can be used as a fuel in compression ignition engine without any engine modifications.

The relevance of the topic is the development of alternative energy and search for new sources of energy as the main world trend of the twenty-first century. Using the energy of earth, wind, water and sun, humanity will stop polluting the environment and save valuable fossil resources. The Republic of Kazakhstan is well known with its stability and successful development. It is quite important not only for the country, but for the whole Central Asian region. Nowadays it is necessary to improve the energy returned on investment, and to make producing it cheaper. Wind power will be nearly very important in coming years. Probably the most established renewable energy source, besides hydro, becomes as cheap as fossil fuels in many markets around the world. The different types of the renewable energy were examined in this article.
