ABSTRACT
A solar cell is a semiconductor device that converts solar energy into electricity by the photovoltaic effect, representing the fundamental power conversion unit of a photovoltaic system ,works under the principle of a P-N junction that absorbs light , releases electrons and holes , creating a voltage in the cell , which is then applied to load; being environmentally aware, and with the price of living rising at an alarming rate, solar power, generating energy from the natural resources of the sun, has in recent times become quite a ....etc

Swimming pools provide a great way toexercise and beat the summer heat. Buildingand maintaining a pool, however, alsomeans relatively high costs added to yourhousehold’s budget. There are severalways that you can reduce operating andmaintenance costs, lower water consumption,and conserve heat if you heat yourpool. Many people heat their pools toextend the swimming season and/or tokeep it at a temperature that they are personallycomfortable with. This lets themenjoy the full value from their pool. Solarpool heaters are an option ....etc

1. Fluorescence brightness control
2. Power switching control (for general loads such as television, radio, etc.)
3. Fans or motor’s inverter control
4. A Warning System on Energy Usage
This whole system can monitor the power usage and display through a LCD Display. Then, it can warn the users through LED bulbs when the power usage is getting close to the monthly prescribed energy usage levels. The project principles can be easily extendable to industrial applications.

Abstract

Here, students learn how harvesting energy from renewable sources will help meet the future needs of society. In the laboratory, the students will develop a system to store energy from a renewable source (represented in the laboratory by a light bulb, a box fan, or flowing water). The students will transport the energy, and use it to supply an electrical load (a light bulb) in a different physical location. In the process, students will learn about energy and power, and will learn about
anal ....etc

Abstract:
The oil shocks of 1970s led to spiraling crude oil prices in the world market which prompted planners to view energy security as an issue of national strategic importance. Energy security has an important bearing on achieving national economic development goals and improving the quality of life of the people. World’s dependence on crude oil will continue for most part of the 21st century but the continued dependence on crude oil is loaded against it with inherent price volatility linked to finite global ....etc
