Dec 6 renewable nonrenewable energy
The document discusses and compares various renewable and non-renewable energy sources, outlining their advantages and disadvantages. It provides details on different renewable technologies like solar, wind, hydro, geothermal, tidal, and biomass power as well as non-renewable sources such as fossil fuels, coal, natural gas, oil, and nuclear power. The document also discusses energy efficiency and conservation as important tools for transitioning to cleaner energy.
Non-renewable energy
Energy is the ability to produce change or do work. There are two main types of energy sources: non-renewable and renewable. Non-renewable sources exist in finite quantities and include fossil fuels like coal, oil, and natural gas. Fossil fuels were formed from the remains of ancient plants and animals. While they provide a large amount of energy, their use also causes pollution and greenhouse gas emissions.
Renewable and non renewable resources
This document summarizes the key differences between nonrenewable and renewable resources. Nonrenewable resources such as coal, petroleum and natural gas cannot be replenished within human timescales, whereas renewable resources like solar, wind and hydropower can be regenerated naturally and quickly. The text provides examples of nonrenewable resources like uranium and fossil fuels that are finite, as well as renewable resources including solar, geothermal, wind, biomass and hydropower that can be sustainably used into the future.
Renewable resources
This document distinguishes between renewable and nonrenewable resources. Nonrenewable resources like fossil fuels cannot be replaced by nature once used up. Fossil fuels include coal, oil, and natural gas. Renewable resources can be naturally replenished, including land, water, and animal resources. However, overuse of renewable resources can cause issues like soil degradation, limited freshwater, and unsustainable use of animals. The document encourages identifying renewable and nonrenewable resources in New York State.
Energy resources
a detailed presentation which emphasizes on the energy resources in the modern world,with a jist of their advantages and disadvantages including modern energy resources with illustrative pictures.
Non renewable resources
The document discusses non-renewable resources like fossil fuels, minerals from mining, and topsoil. It notes that fossil fuels like coal, oil, and natural gas were formed from decomposed organisms over millions of years and are in limited supply. The usage of these non-renewable resources has environmental impacts as burning fossil fuels releases pollutants and plastics are not biodegradable. It suggests reducing consumption and reusing or recycling materials to lessen the environmental effects from exploiting non-renewable resources.
Renewable and Non- renewable energy Sources
Renewable energy is energy which is generated from natural sources i.e. sun, wind, rain, tides and can be generated again and again as and when required. Non-Renewable energy is energy which is taken from the sources that are available on the earth in limited quantity and will vanish fifty-sixty years from now.
Resources [renewable and non renewable]
There are two types of resources: non-renewable and renewable. Non-renewable resources like coal, petroleum, natural gas and uranium are fossil fuels and minerals that were formed over millions of years and cannot be replenished on a human timescale. Renewable resources like solar, wind, hydroelectric, geothermal and biomass can be replenished naturally or through human efforts within a short period of time and do not get depleted. While non-renewable resources are finite, renewable resources are generally more sustainable as they are constantly replenished.

Conservation of non renewable resources
This biology seminar discusses non-renewable resources, specifically fossil fuels. It explains that fossil fuels are formed from the remains of dead plants and animals buried under layers of sediment over long periods of time. As these remains are subjected to high heat and pressure underground, they slowly transform into fossil fuels like coal, petroleum, and natural gas. Fossil fuels are widely used as fuel sources but are only available in limited quantities, so conservation efforts are important. Some ways to conserve fossil fuels discussed include using more efficient forms of transportation, insulation, and alternative energy sources when possible.
Natural resources renewable and non renewable
Natural resources can be classified as either renewable or non-renewable. Renewable resources like sunlight, wind, water and biomass can regenerate themselves over time, while non-renewable resources like fossil fuels and minerals exist in finite quantities and cannot be replenished once depleted. Some key renewable resources discussed include solar, wind, hydro and geothermal energy, each with their own pros and cons. Non-renewable resources outlined are oil, natural gas, coal and nuclear fuels, which all provide important energy but have limited supplies that will eventually be exhausted unless usage is reduced. Conservation of both renewable and non-renewable resources is important to ensure sustainable development.
Renewable energy
This document discusses various sources of renewable energy including fossil fuels, solar energy, geothermal energy, hydro energy, and hydrogen as a potential future fuel. It notes that while fossil fuels currently provide a reliable energy supply, they are non-renewable and cause environmental issues like pollution and global warming. Renewable sources like solar, geothermal, and hydro provide clean energy alternatives, but technologies are not yet mature and established. Hydrogen is highlighted as an ideal future fuel because it is abundant, non-toxic, and can be produced from renewable resources, though safe storage and transportation of hydrogen remains a challenge.

Renewable & Nonrenewable Resources
Nonrenewable resources like coal, petroleum and natural gas cannot be replenished in a short period of time and will eventually run out. They were formed from ancient organisms millions of years ago. Renewable resources such as solar, wind, water and biomass can be naturally replenished in a short period of time through natural processes and are less finite than nonrenewable resources. The key difference between the two is whether the resource can be naturally replenished within human timescales.
energy sources
This document discusses various renewable and non-renewable energy sources. It provides details on solar energy sources like solar cookers and solar water heaters that convert sunlight directly into heat. It also describes solar cells that convert sunlight into electricity. Other renewable sources discussed include wind energy from wind turbines, hydel energy from flowing water, and geothermal from underground heat. Non-renewable sources like fossil fuels are finite, while renewable sources like solar, wind and hydel are either unlimited or can be replenished.
RENEWABLE AND NON RENEWABLE RESOURCES
Renewable and non-renewable resources are classified based on their ability to regenerate. Renewable resources like solar, wind and hydro power can be replenished naturally, do not pollute, and are available in many locations. However, they can be inconsistent. Non-renewable resources like coal, oil and natural gas were created over millions of years and produce greenhouse gases when burned; once depleted they cannot be replaced. Conservation efforts aim to reduce consumption and waste of all natural resources.
Renewable & non renewable resources
The document discusses renewable and non-renewable resources. It defines renewable resources as natural resources that can replenish themselves, such as through biological reproduction, including agriculture, water resources, organisms that provide food/fibers/drugs. Renewable energy sources mentioned include solar, wind, geothermal power. Non-renewable resources are finite and do not replenish in human timeframes, including fossil fuels like coal, petroleum, natural gas. Specific renewable energy sources then discussed in more detail are tidal power, wind power, solar power, hydropower, and thermal energy.
Conventional Energy
The document discusses various conventional sources of energy in the United States, including coal, natural gas, and oil. It notes that over 80% of fossil fuel emissions come from burning coal, oil, and gas. It also discusses emerging unconventional sources of energy such as shale gas, oil sands, and their environmental challenges. The document advocates reducing dependency on fossil fuels through developing renewable energy sources and implementing emission reduction strategies.
Energy
Energy comes in three main forms: fossil fuels, nuclear power, and renewable energy. Fossil fuels such as coal, oil, and natural gas currently account for over 72% of energy usage but contribute to global warming. Nuclear energy provides power through splitting atoms in reactors but produces radioactive waste. Renewable energies like solar, hydroelectric, tidal, geothermal, and wind offer greener alternatives but are currently more expensive. Economic development depends on affordable energy sources, so countries utilize a variety of fuel sources.
Non renewable energy sources
This document discusses different types of energy sources including renewable and non-renewable sources. It provides information on where various energy sources come from such as coal forming from decaying plants deep underground. It also discusses how these sources are used including coal being burned for heat and light and oil and natural gas being extracted through various methods like offshore drilling rigs. The document notes that non-renewable sources like coal, oil, and natural gas will eventually run out so renewable sources will be needed.

It also covers renewable energy sources like solar, wind, and hydroelectric versus non-renewable sources like fossil fuels. Examples are given of different machines that convert these energy forms like steam engines, internal combustion engines, steam turbines, and gas engines. The environmental impacts of generating, transmitting, distributing, and using energy are also summarized.
Natural Resources and its types in detail
This document discusses various types of natural resources including renewable and non-renewable energy and water resources. It defines renewable resources as those that can be replenished relatively quickly, like sunlight, air, water, while non-renewable resources exist in fixed amounts and are depleted over time, such as fossil fuels and minerals. It also describes different sources of fresh water including surface water, groundwater, and stored rainwater. It outlines various uses of water resources including domestic, industrial, recreational, and public uses as well as the factors that influence water demand in cities and towns.
Non renewable-energy
Non-renewable energy resources such as fossil fuels are finite and will be depleted within 50-60 years. They include coal, petroleum, and natural gas, which were formed from the remains of dead plants and animals over millions of years. While reliable sources of electricity, their use also produces greenhouse gases and other pollutants that harm the environment and health. Nuclear energy generates power through nuclear fission or fusion, but poses challenges of nuclear waste storage and safety. Both non-renewable and nuclear energy have benefits as well as drawbacks to consider regarding sustainability and environmental protection.
Greenhouseeffect
The document discusses the greenhouse effect and global warming. It explains that greenhouse gases like carbon dioxide, methane, and CFCs trap heat in the atmosphere and cause the planet to warm up. As a result, sea levels are rising and extreme weather events like droughts and floods are becoming more common. The summary concludes that if greenhouse gas emissions continue unchecked, the environmental crisis will negatively impact human health, property, and economic costs.
Sources of energy (1)
This document discusses different sources of energy. It begins by explaining that energy is essential for human life and activities. The main sources of energy discussed are solar energy, wind energy, chemical energy from plants, and fossil fuels like coal, petroleum and natural gas which all ultimately derive from solar energy. It then examines characteristics of good sources of energy and fuels. Specific fossil fuels are described in detail along with their uses. Other sources discussed include hydroelectric power, biogas, hydrogen fuel, and wind energy. Advantages and disadvantages of each source are provided.
sources of energy
Energy is defined as the ability to do work and exists in different forms that can be converted from one to another. Energy sources can be renewable like wind and solar that can be replenished, or non-renewable like fossil fuels that are limited. Fossil fuels are a conventional energy source but have disadvantages like pollution and contributing to climate change. They are not renewable as once burned, there is no more.

Climate change
Climate change refers to the rising average temperature of the Earth's atmosphere and oceans caused by increased levels of greenhouse gases like carbon dioxide from human pollution. This greenhouse effect traps heat from the sun but has become dangerous due to increased pollution. Climate change leads to natural disasters like floods and fires as well as threats to biodiversity and ecosystems as the climate changes.

Explica que la inteligencia colectiva depende más de la capacidad de diálogo y sensibilidad social que de las inteligencias individuales. También describe algunas experiencias colaborativas realizadas en un instituto español utilizando wikis, blogs, redes sociales y foros para proyectos en diferentes asignaturas.
Present baruffi in inglese
The document summarizes the poor condition of windows, radiators, doors, and walls at a school. It notes that windows are deteriorated and in need of repair, radiator valves need replacing, and doors and walls have cracks. Temperature readings are provided from different classrooms and areas of the school taken on the same day, with readings as high as 26 degrees Celsius. The document suggests installing thermostatic valves and turning lights off when classes are empty to reduce energy waste and expenses from heating and lighting.
Pacto educativo
El documento propone diez ideas para lograr un pacto necesario en educación en España. Primero, se debe terminar con los constantes cambios legislativos que producen desconcierto. Segundo, se debe partir de análisis rigurosos de la realidad educativa en lugar de eslóganes. Tercero, se debe garantizar la extensión y consolidación de la red pública de enseñanza.

Proyecto Tic 4eso
El documento propone un enfoque distinto para la enseñanza de TIC en 4o de la ESO que dé más protagonismo al alumnado y fomente su autonomía y trabajo colaborativo. La metodología consiste en que los alumnos trabajen en grupos para desarrollar blogs sobre diferentes temas, aprendiendo los unos de los otros. Esto requiere que el profesor adopte un rol de facilitador y que los alumnos se responsabilicen de su propio aprendizaje.

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.
