Wave energy comes from ocean waves that are caused by wind blowing over the surface of the water. There is a lot of energy in ocean waves that can be harnessed through wave power devices. One method of capturing wave energy works similar to a swimming pool wave machine but in reverse, using the motion of waves to drive air in and out of a chamber to power a turbine and generator. While wave energy is a renewable source that produces no emissions, a consistent wave source is required and devices must be able to withstand rough ocean weather.

Wave energy is the energy captured from ocean or sea waves and is also known as ocean energy or sea wave energy. Waves are generated by wind passing over the sea surface, transferring energy from the wind to the waves. The amount of energy transferred depends on factors like wind speed and duration. Wave energy conversion technologies include attenuators, oscillating wave surge converters, oscillating water columns, overtopping devices, and point absorbers. These devices extract energy from wave motion and convert it to electricity via hydraulic pumps, turbines, or linear generators. While wave energy is renewable and abundant, challenges include the effects on marine ecosystems, high costs, and intermittent nature of wave resources.

wave power and wind wave powered car
Wind power can be used to power vehicles. Wind turbines and valves are placed on cars to harness wind and convert it to electrical energy to power the car. The valves intake wind which is then converted to electricity via an alternator. This electricity powers the car. Wind power cars have advantages like being pollution-free and using a renewable source of energy. However, disadvantages include wind strength variations and the potential for turbines to be seen as unsightly. Overall, wind power cars can be an environmentally friendly transportation option.
Ocean Power Generation
The presentation gives you information regarding to various methods of harnessing electricity from ocean.
Tidal and Wave Power
Wave power devices take energy directly from surface waves or pressure fluctuations below the surface to generate electricity, while tidal power uses turbines under water that spin to generate electricity from rising and falling tides. The main difference is that wave power devices are located on the water surface, while tidal power turbines are submerged underwater. Both capture the mechanical energy from ocean waves and tides to generate electrical energy that can power homes, schools, and small businesses.
Physics (waves)
Wave energy refers to capturing the energy from ocean surface waves to generate electricity. Larger waves contain more power but other factors like wave speed, wavelength, and water density also determine wave power. Wave power levels vary depending on the location, with some areas having consistently strong waves suitable for wave energy conversion. While wave energy is a renewable source that produces no emissions, the variable nature of wave strength can sometimes result in inconsistent energy production. Devices must also be able to withstand harsh ocean 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.

Wave energy
- 1. Wave Energy
- 2. Where does it come from? The energy comes from waves. Waves are caused by wind blowing over the ocean. In many areas of the world, the wind blows with enough consistency and force to provide continuous waves. There is tremendous energy in the ocean waves. Wave power devices extract energy directly from the surface motion of ocean waves or from pressure fluctuations below the surface.
- 3. How is electricity produced? There are several methods of getting energy from waves. One of them works like a swimming pool wave machine in reverse At a swimming pool, air is blown in and out of a chamber beside the pool, which makes the water outside bob up and down, causing waves. At a wave power station, the waves arriving cause the water in the chamber to rise and fall, which means that air is forced in and out of the hole in the top of the chamber. We place a turbine in this hole, which is turned by the air rushing in and out. The turbine turns a generator.
- 4. What are the advantages? The advantages of Wave Energy are: It is completely renewable.The energy is free - no fuel needed, no waste produced.Not expensive to operate and maintain.Can produce a great deal of energy.
- 5. What are the disadvantages? The disadvantages of Wave Energy are: It depends on the waves - sometimes you'll get loads of energy, sometimes almost nothing.Needs a suitable site, where waves are consistently strong.Some designs are noisy. But then again, so are waves, so any noise is unlikely to be a problem.Must be able to withstand very rough weather.
