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.

Non renewable source of energy
Non-renewable sources of energy include fossil fuels like coal, petroleum, and natural gas. Coal is formed from the decomposition of dead plants over millions of years. Oil and natural gas are also formed from dead plankton that sank to the ocean floor and were buried under layers of sediment. While abundant and affordable, non-renewable energy sources damage the environment when burned due to emissions and pollution, and they will eventually be depleted since they cannot be replenished.
3. Environmental Science Lesson 3.pptx
This document contains an environmental science lesson that discusses sustainability and different types of resources. It defines sustainability as "meeting the needs of the present without compromising the ability of future generations to meet their own needs." The document categorizes resources as perpetual renewable resources, intermediate renewable resources, and non-renewable resources. It provides examples for each category such as solar, wind, and geothermal energy for perpetual renewable resources. The document also discusses how resources like fresh water, soil, crops and trees can be overused if regeneration rates are exceeded, making them intermediate renewable resources. Non-renewable resources like fossil fuels are finite and include oil, natural gas, coal, and nuclear energy.
Sources of energy
Energy can be obtained from various sources and is divided into conventional and non-conventional sources. Conventional sources include fossil fuels like coal, petroleum and natural gas, which were formed from the remains of ancient plants and animals but are being depleted. Non-conventional sources include renewable energy from solar, wind, and hydroelectric power. Fossil fuels are a non-renewable source and their combustion causes air and water pollution and global warming, so they must be used judiciously and alternatives developed.

Natural rresources conservation by Muhammad Fahad Ansari12IEEM14
The document discusses natural resources and their conservation. It defines natural resources as materials needed to sustain life that come from nature, such as air, water, land, forests and minerals. Resources are classified as renewable, like sunlight, water and trees; and non-renewable, like coal, which do not regrow or take a very long time to regrow. The document emphasizes the importance of conserving non-renewable resources as human demand increases and stresses the need for sustainable use of the Earth's resources to protect ecosystems.
Natural Resources-Power From the Environment
This is a description of each of the earths natural resources, how they work, and how they affect the environment.
0708_renewable_nonrenewable-2.ppt
Nonrenewable resources such as coal, petroleum and natural gas cannot be replenished in a short period of time or regrown at the rate they are consumed. They are considered fossil fuels and their use can cause land disturbance, destruction of wildlife habitats, and water and air pollution. Renewable resources such as air, water, land, wildlife and renewable energy from solar, wind and hydro sources are naturally replenished and have an unlimited supply. They are more environmentally friendly sources of energy that can increase public health and jobs while providing long-term energy independence. Both renewable and nonrenewable resources are important but nonrenewable resources are running out and harming the environment so we must reduce their use and develop more

Energy
This document discusses different forms of energy including renewable and non-renewable sources. It explains that energy exists in many forms such as electricity, heat, light and sound. Non-renewable sources like coal, natural gas and nuclear energy cannot be easily replenished. Renewable sources include solar, wind, hydroelectric, geothermal and tidal energy which are replenished naturally. Solar energy is one of the most abundant renewable resources and can be harnessed using photovoltaic and solar thermal technologies to generate electricity or heat. The document also discusses the importance of energy conservation and reducing energy crisis through judicious utilization of resources.
Geography vocabulary bbc bitesize
The document defines over 50 terms related to geography, climate change, and the environment. Some key terms include:
- Adaptation: Actions taken to avoid or deal with the impacts of climate change through planning or in response to changes.
- Aerosol: Tiny solid or liquid particles in the atmosphere from natural or human sources that can warm or cool the climate.
- Atmosphere: The layer of gases surrounding Earth that supports life through processes like photosynthesis.
- Carbon dioxide: A colorless, odorless greenhouse gas produced by decay, respiration, and burning fossil fuels. Increased levels are the main cause of global warming.
- Climate change: Significant long-term shifts in weather patterns and other climate factors
Types Of Power
The document discusses various sources of energy including fossil fuels like coal, petroleum and natural gas. It also discusses nuclear fission which involves splitting atoms to produce energy. Nuclear waste is a concern. Hydroelectric power uses the kinetic energy of moving water through turbines. Biomass, wind, solar, geothermal and nuclear fusion are also renewable energy sources discussed in the document. Methods of storing various energy sources include containers, tanks, batteries and splitting water.
Conventional and non Conventional Resources
Conventional resources like coal, oil and natural gas are traditional energy sources that form over long periods from decaying organic matter. However, they release greenhouse gases when burned. Non-conventional resources such as solar, wind, hydropower and geothermal are increasingly important as they are renewable, pollution-free alternatives to conventional sources. Non-conventional energy comes from ongoing natural processes like sunlight, wind and tides rather than finite fossil fuels.
Natural resources lecture
The document classifies natural resources based on their origin, stage of development, and renewability. It provides examples of biotic and abiotic resources classified by origin. Potential and actual resources are classified by stage of development. Renewable resources like sunlight, wind, and hydroelectric power are replenishable, while non-renewable resources like fossil fuels and minerals are not. Examples of renewable energy sources include solar, wind, hydroelectric, and geothermal power. Non-renewable resources discussed are fossil fuels like coal, petroleum, and natural gas formed from ancient organic matter, as well as mineral resources.
Non renewable resource
This document discusses non-renewable resources. It defines non-renewable resources as those that do not replenish themselves quickly enough to be considered sustainable. Examples given are fossil fuels like coal, petroleum and natural gas. It notes that these fuels were formed over millions of years from ancient organic materials. In contrast, renewable resources like sustainably harvested timber and wind power can replenish on human timescales. Fossil fuels are difficult to obtain but provide large amounts of energy. The top oil and gas producing countries are also listed. Nuclear fuels obtained from uranium mining are also considered non-renewable but can generate energy cleanly. Non-renewable resources are finite and will eventually be depleted as they cannot repl

How to Manage Reception Report in Odoo 17
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.

Resources [renewable and non renewable]
- 1. RESOURCES
- 3. NON RENEWABLE RESOURCES A nonrenewable resource is a natural resource that cannot be re-made or re-grown at a scale comparable to its consumption.
- 4. NUCLEAR ENERGY Nuclear fission uses uranium to create energy. Nuclear energy is a nonrenewable resource because once the uranium is used, it is gone!
- 5. Fossil Fuels Fossil fuels take millions of years to form. They are the product of the fossilized remains of dead plants and animals that have been exposed to the heat and pressure deep within the earthโs crust. There are many types of fossil fuels, such as petroleum (gasoline), natural gas, and coal.
- 6. COAL, PETROLEUM, AND GAS Coal, petroleum, and natural gas are considered nonrenewable because they can not be replenished in a short period of time. These are called Fossil fuels.
- 7. HOW IS COAL MADE ???
- 8. HOW ARE OIL AND GAS MADE ???
- 9. RENEWABLE RESOURCES Renewable resources are natural resources that can be replenished in a short period of time.
- 10. SOLAR The sunโs rays are used for energy by organisms that undergo photosynthesis. Nearly every organism on the planet gets energy through photosynthesis, directly or indirectly. There are also ways that people can utilize the energy that the sun provides.
- 11. GEOTHERMAL Geothermal energy is thermal energy generated and stored in the Earth. Earth's geothermal energy originates from the original formation of the planet, from volcanic activity, and from solar energy absorbed at the surface.
- 12. WIND Wind is caused by the uneven heating of the atmosphere. Some areas of the world, such as costal regions, have more wind than others because the terrain of the area is relatively flat and has few obstacles to block the wind from blowing. The wind blows naturally โ it is not caused by human activity, and it cannot be used up.
- 13. BIOMASS Biomass, a renewable energy source, is biological material from living, or recently living organisms, such as wood, waste, (hydrogen) gas, and alcohol fuels. Biomass energy is derived from five distinct energy sources: garbage, wood, waste, landfill gases, and
- 14. HYDROELECTRIC Hydroelectricity is the term referring to electricity generated by hydropower ; the production of electrical power through the use of the gravitational force of falling or flowing water. It is the most widely used form of renewable energy.
