Abstract - Renewable energy technologies are appropriate for off-grid services, serving the remote areas while not having to
create or extend high priced and complex grid infrastructure. Thus standalone system using renewable energy sources have become a most popular possibility. Uses of hybrid energy systems, benefits of hybrid energy systems, problems and issues associated to hybrid energy systems and a summary of energy storage technologies for renewable energy systems are put forward. This paper conjointly highlights the long run trends of Hybrid energy systems, which represent a encouraging sustainable solution for power generation.[1]

Energy is a very important input in every sector of any countries economy. The day-by-day increasing population and decreasing typical sources for power generation, provides a necessity to consider the non-conventional energy resources. In our paper, we are looking forward to conserve the kinetic energy that goes wasted, while vehicles move. The number of vehicles passing over speed breaker on road is increasing at a high rate. Below every speed breaker, setting up an electro-mechanical unit said to be power hump (made of piezoelectric material), could help us preserving this energy and utilize it for power generation. Piezoelectricity is the occurrence of an electrical potential (or a voltage) across the sides of a crystal when subjected to mechanical stress (by squeezing it). The electrical output is improved by setting these power humps in series. Using different electrical devices, we store the generated power. We supply this energy to street lights, traffic lights, and neighboring areas, and thereby help in country’s economy. We plan to make it more efficient, by using solar panels that provides for power needs while the vehicles were not in motion. A wind turbine converts the kinetic energy of the motion of the wind to mechanical energy transmitted by the shaft. A generator converts this mechanical energy to electrical energy. So it is necessary to keep in m ind, while designing the windmill’s structural part.
2. SYSTEM OVERVIEW In this system, we draw out energy from four sources. These four sources are- Solar PV cell, vertical shaft wind turbine, roller and piezoelectric crystal .The energy extracted from these sources is stored in a battery. Later, this stored energy is employed for controlling power in street lights. This is a very economical system as it reduces electricity wastage. In this proposed system only 50% of the street lights glows when there is no vehicle on the road. When a vehicle passes by all the lights will be lit. A wind mill is machine for wind energy conversion.
