Abstract: Man has needed and used energy at an increasing rate for the sustenance and well-being since time immemorial. Due to this a lot of energy resources have been exhausted and wasted. Proposal for the utilization of waste energy of foot power with human locomotion is very much relevant and important for highly populated countries like India where the railway station, temples etc., are overcrowded all round the clock. When the flooring is engineered with piezo electric technology, the electrical energy produced by the pressure is captured by floor sensors and converted to an electrical charge by piezo transducers, then stored and used as a power source. And this power source has many applications as in agriculture, home application and street lighting and as energy source for sensors in remote locations. This paper is all about generating electricity when people walk on the Floor. Think about the forces you exert which is wasted when a person walks. The idea is to convert the weight energy to electrical energy The Power generating floor intends to trans- late the kinetic energy to the electrical power. Energy Crisis is the main issue of world these days. The motto of this research work is to face this crisis somehow. Though it won't meet the requirement of electricity but as a matter of fact if we are able to design a power generating floor that can produce 100W on just 12 steps, then for 120 steps we can produce 1000 Watt and if we install such type of 100 floors with this system then it can produce 1MegaWatt. Which itself is an achievement to make it significant. Keywords: Piezoelectric sensor, Footstep, remote location, force and pressure, power generation

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

A palhada representa um terço da energia primária da cana-de-açúcar, mas a sua utilização ainda é incipiente, apesar da grande potencialidade para o seu aproveitamento. O objetivo do trabalho foi avaliar o potencial de geração de energia elétrica da palhada de cana-de-açúcar em conjunto com o bagaço, através de uma análise técnico-econômica. Realizou -se o dimensionamento de uma frota dedicada ao recolhimento da palhada e de uma nova planta de cogeração, com substituição das caldeiras e turbinas existentes, inclusive as turbinas de acionamento dos equipamentos de preparação e extração, em uma usina típica do norte do Paraná. Foram estimados os investimentos necessários para a aquisição dessa frota e da modernização proposta para a área industrial. Os custos do recolhimento da palhada e da geração de energia elétrica foram calculados, bem como o preço mínimo de venda da energia. Também foram calculados a quantidade de consumidores residenciais e os municípios que poderiam ser abastecidos por essa energia. A capacidade de exportação é de 111,912 kWh por tonelada de cana-de-açúcar, com custo da palhada no pátio de bagaço da usina a R$68,08 t-1, custo da energia-elétrica de R$125,55 MWh e preço mínimo de comercialização da energia a R$316,64 MWh. A energia elétrica exportada pode atender uma população de 87.946 pessoas, o que corresponde a energia consumida pela cidade onde estaria localizado o projeto e de mais seis municípios canavieiros do Norte do Paraná. O projeto proporciona a criação de 96 novos empregos diretos.PALAVRAS-CHAVES: Cogeração, eletricidade, bioenergia, biomassa, enfardamento. TechnIC-economic evaluation of sugarcane straw FOR power generation in ParanA STATEABSTRACT: The straw represents one-third of the sugarcane’s primary energy, but its exploitation is still incipient, despite having a huge potential for its utilization.

This research work presents shading of building in hot and dry climate areas using rooftop photovoltaic arrays. Electrical power generation using photovoltaic arrays helps in reducing dependency on the utility grid. Areas with high intensities of solar radiation for a longer duration of time create high daily temperature. The Kingdom of Saudi Arabia (KSA) falls in high temperature and very low humidity climate zone. KSA has increased electricity tariff rates by 260% since 1 January 2018, has planned goals of generation of 9.5 gigawatts of renewable energy by 2030, and has ideas of constructing a self-sustainable city by the Red Sea. Energy analysis performed in this research is to calculate benefits of placing photovoltaic arrays on a rooftop of Buildings. These benefits include the electrical energy production and reduction of building cooling load by shading effect on a rooftop. By placing photovoltaic arrays on rooftop, up to 23% energy saving of cooling load can be achieved. The net annual output of photovoltaic generation per panel is discussed by adding energy generation and saving in cooling load of the building. The distance between the photovoltaic arrays is optimized for maximum benefits of electrical energy and saving in cooling loads. Practical application: Photovoltaic arrays on rooftops for shading effect have practical benefits of energy savings in hot environment areas where high solar irradiance heat up the buildings. Photovoltaic arrays provide shading and energy generations which is a step towards zero energy buildings.

AbstractThe consumption of energy has always been in exponential growth and also there is always an increasing demand in the requirement of energy in some way or the other. So, there is a need to search for energy availability from alternate sources of energy. The utilization of waste energy of foot power with human locomotion is relevant and important for highly populated countries like India where the railway station, temples, etc., are overcrowded all round the clock. When the flooring is engineered with piezoelectric technology, the electrical energy produced by the pressure is captured by floor sensors and converted to an electrical charge by piezo transducers, then stored and used as a power source. This paper deals with the generation of alternate sources of energy through piezoelectric materials. This research describes the use of piezoelectric materials to harvest energy from people walking vibration for generating and accumulating energy. This study also studies the perceptions and adaptability of piezoelectricity. The adaptability of piezoelectric technology in a real-time environment has been studied by comparing the overall cost of generating electricity with solar energy. This study also suggests a footstep of the piezoelectric energy harvesting model which is cost-effective and easy to implement.

This paper presents an energy plan for harnessing electrical power from hybrid energy resources, including biomass and solid waste, through hybrid technologies for microgrid development to overcome the current energy crisis and provide future sustainable electricity pathways for a developing country. Biomass and solid waste were collected from different dumping sites in Pakistan and were tested for their calorific value, which was found to be 6519Kcal/Kg. The total power was calculated based on this calorific value and it was found that there is a potential of total 11,989.5GW of power generation. Thus, hybrid energy resources are suitable for harnessing electrical energy through hybrid technologies. Different hybrid systems were examined for these resources and the gasification technique is finally proposed as the most suitable method for producing energy from biomass and solid waste resources in Pakistan. This technique is also found to be economically feasible for processing all kinds of waste.

Ocean energy holds out great potential for supplying remote maritime areas with their energy requirements, where the grid size is often small and unconnected to a continental grid. Thanks to their high maturity and competitive price, solar and wind energies are currently the most used to provide electrical energy. However, their intermittency and variability limit the power supply reliability. To solve this drawback, storage systems and Diesel generators are often used. Otherwise, among all marine renewable energies, tidal and wave energies are reaching an interesting technical level of maturity. The better predictability of these sources makes them more reliable than other alternatives. Thus, combining different renewable energy sources would reduce the intermittency and variability of the total production and so diminish the storage and genset requirements. To foster marine energy integration and new multisource system development, an up-to-date review of projects already carried out in this field is proposed. This article first presents the main characteristics of the different sources which can provide electrical energy in remote maritime areas: solar, wind, tidal, and wave energies. Then, a review of multi-source systems based on marine energies is presented, concerning not only industrial projects but also concepts and research work. Finally, the main advantages and limits are discussed.
