The production and use of oil and other fossil fuels continues to rise on a yearly basis to record new levels. At the same time, fewer new oil fields are being identified which means that sometime over the next few decades oil production will not be able to satisfy our demand. Not only are we running out of oil, but also our use of fossil fuels is putting an increasing burden on the environment in terms of greenhouse gases and global warming. Alternative energy sources are known, but their efficiency based on cost is poor. Nanotechnology advances can improve this. In this paper we are going to discuss upon how the advances in nanotechnology can improve the efficiency of the alternative energy sources. Here we are going to discuss the improvements using the advances in nanotechnology in the areas like insulation, thermoelectricity, portable power, solar and hydrogen.
Energy is the key input to drive and improve the life cycle the consumption of energy is directly proportional to the progress of the mankind with ever growing population improvement in the living standards of the humanity, industrialization development of the developing countries like India. The global demand for energy is increasing on alarming rate. The primary source of energy is fossil fuels (like coal, diesel, petrol), which are decreasing day by day due to more energy demand and there is global warming (increasing of co2 and so2) problem due to consumption these sources. We the of view of next generation to come we need to utilize the limited sources in a careful manner and also try to invent some alternative techniques for a effective productions and conservation of energy. Recent improvement in the power conversions efficiency of organic solar cells has brought renewed attentions to the possibility of practical large-scale use of these devices. This paper deals with the basic principle of operation of plastic solar cell and we demonstrate the implementation of nano-rods and screen-printing technology in the fabrications of organic bulk hetero junction solar cells. One of the renewable energy technology is photovoltaic, the technology that directly convert sunlight into electricity. The new photovoltaic technology, plastic solar cell technology is based on conjugate polymers and molecules.
The subject power quality engineering truly encompasses most areas of electrical engineering from generation to utilization. Power quality problems are mainly due to two reasons. One is the characteristic of the power supply voltage and the electrical system that effect the performance of the load and the other is the characteristics of the load that affect the electrical system or other loads. The presentation starts with the necessity of quality in electrical power by pointing the causes and consequences that isolates the electrical power from its quality on demand like voltage sags and swells, harmonics. Various solutions from the innovative technology those packs the power with its at most quality are presented. Not only various guidelines to maintain the power quality but also the analysis and monitoring of power quality are vividly highlighted.
Geothermal energy is energy derived from the heat of the earth’s core. It is clean, abundant, and reliable. If properly developed, it can offer a renewable and sustainable energy source. There are three primary applications of geothermal energy: electricity generation, direct use of heat, and ground- source heat pumps. Direct use includes applications such as heating buildings or greenhouses and drying foods, whereas ground source heat pumps are used to heat and cool buildings using surface soils as a heat reservoir. This paper covers the use of geothermal resources for production of utility-scale electricity and provides an overview of the history, technologies, economics related to geothermal power.
Have you ever imagined of running your car with water as fuel, which is “THE ELIXIR OF LIFE”. So here we are going to bring forth before you a technology, which employs this formula. Water is converted into a gas called Brown’s gas, which provides the necessary push for the car. With the help of this technology we can avoid the harmful effects produced by petroleum products. The emission of this car is water vapor, which is eco-friendly. Only 1litre of water produces 1864grams of fuel, which also reduces the cost.
An electric car running on FREE ELECRICITY!! Too fantastic to believe, isn’t it?

Well, There but not quite. Simplicity is the crux of this design – “2 Pairs of wind turbine jets mounted on the roof of the car, converting the rotations of the blades
into electrical power, during its motion”. As mentioned, the turbine jets are fitted with motion, torque & direction sensors so as to align the turbines with the wind direction, with any perceptible change in it. Primary and Secondary wind re-directors mounted on the bonnet and at the windscreen flanks tend to re-direct the wind-flow towards the turbines, augmenting their performance. A high capacity capacitor assembly installed between the turbines and the car battery unit (C.B.U) facilitates charge storage and acts as DC buffer eliminating the need for on-demand online charging of the C.B.U. It can be demonstrated that a saving of 30-40% of the input can be realized even after making allowances for the extra weight of the turbines, capacitors, assembly and fittings.

This study presents a novel method to detect and classify power quality disturbances using wavelets. The proposed algorithm uses different wavelets each for a particular class of disturbance. The method uses wavelet filter banks in an effective way and does multiple filtering to detect the disturbances. A qualitative comparison of results shows the advantages and drawbacks of each wavelet when applied to the detection of the disturbances. This method is tested for a large class of test conditions simulated in MATLAB. Power quality monitoring together with the ability of the proposed algorithm to classify the disturbances will be a powerful tool for the power system engineers.

Cold Fusion is the fusion of hydrogen atoms into helium at room temperature. In 1989 two scientists announced that they had produced cold fusion in their laboratory, an achievement that if true would have meant a virtually unlimited cheap energy supply for humanity. This paper presents an overview of low energy nuclear reactions, a subset of the field of condensed matter nuclear science. Condensed matter nuclear science studies nuclear effects in and/or on condensed matter, including low energy nuclear reactions, an entirely new branch of science that widespread attention and notoriety beginning in 1989 with the announcement of a previously unrecognized source of energy by Martin Fleischmann and Stanley Pons that came to be known as cold fusion. Two branches of LENR are recognized. The first includes a set of reactions like those observed by Fleischmann and Pons that use palladium and deuterium and yield excess heat and helium-4. Numerous mechanisms have been proposed to explain these reactions, however there is no consensus for, or general acceptance of, any of the theories. The claim of fusion is still considered speculative and, as such, is not an ideal term for this work. The other branch is a wide assortment of nuclear reactions that may occur with either hydrogen or deuterium. Anomalous nuclear transmutations are reported that involve light as well as heavy elements. The significant questions that face this field of research are: 1) Are LENRs a genuine nuclear reaction? 2) If so, is there a release of excess energy? 3) If there is, is the energy release cost effective?
As the field of energy management matures, so do the tools and best practices available to ensure that the energy required by an organization is used in the most efficient way possible. In the past, energy anagement practices consisted primarily of replacing efficient equipment and then using any number of methods to estimate the savings gained. Studies reformed by the Department of Energy (DOE) and he Texas State Energy Conservation Office (SECO) are shown, however, that energy savings can be automatically increased and maintained over time by doping and implementing consistent energy management practices and recognized measurement and verification procedures. As energy management standards and best practices begin to see widespread adoption, the information systems required to support them will play a crucial role in their implementation and success. These enterprise energy management (EEM) systems can provide the detailed data and analysis capabilities required to ensure energy management strategies and conservation measures are on track throughout an organization. Organizations can apply EEM systems to gain a comprehensive understanding of current energy performance plan and select cost effective energy conservation measures, track performance of measures that have been implemented and verify the savings realized.
Electrical energy plays a very prominent role in the growth process of any economy, whether it is developing or developed. It is needed for industry, agriculture, transport, domestic, and many other activities that create employment, produce goods and services, and generally affect the day-to-day lives and the standard of living of the people. The limitations associated with “conventional” energy sources have highlighted the necessity for diversification and expansion of the energy resource base. This creates a major shift in attitudes to energy developments has also provided a substantial impetus to the reappraisal of this renewable energy sources in an effectual manner. Wind is defined as air in motion. This motion can be in any direction, but in most cases the horizontal component of wind flow greatly exceeds the flow that occurs vertically. The speed of wind varies from absolute calm to speeds as high as 380 kilometers per hour. These greater speeds can efficiently used for the generation of electricity. Wind power is one of the fastest-growing clean energy sectors worldwide. It has potential to become a viable option for large scale, base load generation in INDIA. Floating windmills are the most attractive method, having reduced environmental and ecological impacts so, in this paper we present the emerging technology of utilizing this WIND POWER to extract maximum energy in an economical way using floating windmills.

The internal combustion engine (ICE) finds its place in the market with latest design modifications in various components to improve efficiency, economy and overall performance. The internal combustion engine is the key to the modern mechanizing world. However, one component has remained unchanged in the internal combustion engine development i.e., the camshaft, has been the primary means of controlling the valve actuation and timing, and therefore, influencing the overall performance of the vehicle. Cam less technology is capturing the future of internal combustion engines. It  has been known to man that if valves could be controlled independently in an Internal Combustion Engine then there would be benefits like increased power, reduced emissions and increased fuel economy. In the cam less technology valve actuators of electro-mechanical and electro-hydraulic type operate valve motion. In this paper we compare cam less valve operation with conventional valve operation and we deal with the valve actuating mechanisms of cam less engine by considering the electromechanical and electro hydraulic actuators as the important types of actuating valves in cam less engines.
