This paper proposes a low-cost electric field energy harvester that can be integrated into the enclosure of smart grid sensors monitoring medium-voltage to high-voltage utility assets. The harvester is designed to harness the abundant electric fields near these assets to power the sensors. A prototype was built and tested on a 35-kV bus, providing 17 mW of continuous power, enough to operate a low-duty-cycle wireless voltage sensor attached to the asset. The harvester has a shape that allows installation without interrupting the asset and can be used with multiple assets.wsn
A WSN primary outline issue for a sensor system is protection of the vitality accessible at every sensor node. We propose to convey different, versatile base stations to delay the lifetime of the sensor system. We split the lifetime of the sensor system into equivalent stretches of time known as rounds. Base stations are migrated toward the begin of a round. Our strategy utilizes a whole number straight program to focus new areas for the base stations and in view of steering convention to guarantee vitality proficient directing amid every round. We propose four assessment measurements and look at our answer utilizing these measurements. Taking into account the reproduction results we demonstrate that utilizing various, versatile base stations as per the arrangement given by our plans would altogether expand the lifetime of the sensor system.

Solar energy harnesses power from the sun and can be used as an alternative to fossil fuels. It is a renewable and clean energy source. Solar power systems generally consist of solar panels that convert sunlight to electricity, solar inverters that change the direct current to alternating current, and batteries that store energy for use when the sun is not shining. Solar energy can be used to provide electricity for homes, reduce energy bills, increase home value, and have positive environmental impacts through reduced carbon emissions. It is also a viable energy source for lighting, fans, water heating and charging small devices.

Solar mission
Solar electric systems use photovoltaic solar cells to convert sunlight directly into electricity, which charges batteries and is then used via inverters or converters for applications like lighting and pumping. Solar thermal energy uses collectors to harness heat from the sun at different temperatures for pools, water/air heating, or electricity production. Wind turbines ranging from 600 kW to 5 MW use airflows to generate power and are sited in locations with stronger, steadier winds like offshore or at high altitudes. Hydroelectric systems capture the kinetic energy of water without dams using micro-hydro or run-of-river designs to generate under 100 kW or derive power from rivers and oceans, respectively. Biomass functions as a natural battery by storing the

Solar energy and types of solar energy
Solar power harnesses energy from sunlight and converts it into thermal or electrical energy. There are several types of solar energy technologies including passive solar, which uses sunlight for heating and cooling without mechanical systems, active solar involving collectors and pumps, concentrating solar power that uses mirrors to focus sunlight and generate heat, and photovoltaics that directly convert sunlight to electricity using solar cells. Concentrating solar power systems use mirrors to focus sunlight to create steam that drives turbines to generate electricity, while photovoltaic panels directly convert sunlight to electricity through the photovoltaic effect. Solar energy has advantages of being renewable, pollution-free, and having low maintenance once installed, though the initial costs are high and it relies on sunny weather conditions

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
