Conservation of non renewable resourcesHarsh Kalode
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.
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.
Fossil fuels such as coal, oil, and natural gas are formed from the remains of ancient plants and animals. They are burned to power steam turbines that generate electricity. While they provide a large amount of energy, burning fossil fuels also produces air and water pollution and contributes to climate change. Hydroelectric power harnesses the potential energy of water behind dams by passing it through turbines to generate electricity. It is a renewable source that does not produce pollution once constructed, but dams are very expensive to build and can disrupt local environments and wildlife.
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.
Fuels provide energy through a process of energy transformation called combustion. The three major fossil fuels are coal, oil, and natural gas. Fossil fuels are nonrenewable resources that were formed over millions of years from the remains of ancient organisms. While fossil fuels provide a large amount of the energy used today, they are being consumed faster than they are produced, so new energy sources will be needed to replace decreasing fossil fuel reserves.

Renewable resources like solar, wind, water, and geothermal energy are also introduced. The document outlines different processes used to extract and utilize these various resources.
Renewable and non-renewable energy resources and the importance of energy conservation are discussed. Renewable resources include solar, wind, hydroelectric, geothermal, and biofuels which can be replenished. Non-renewable resources like coal, oil and gas are limited and their extraction causes environmental damage. Conservation of energy through efficient use and recycling is emphasized to reduce pollution and delay depletion of non-renewable resources.
Fossil fuels such as coal, oil, and natural gas are important energy sources that are formed over millions of years from the remains of ancient plants and animals. They provide energy for heating homes, fueling vehicles, and powering industry. However, fossil fuels are finite resources that are being consumed much faster than they are formed, so once they are depleted there will be none left for future generations.
Modern society requires large quantities of energy generated from nonrenewable and renewable natural resources. Nonrenewable resources include fossil fuels like oil, natural gas and coal, as well as nuclear energy. Oil and natural gas are extracted via drilling while coal forms from the decomposition of ancient organic matter and ranges in quality based on carbon content. Burning fossil fuels and mining coal causes environmental damage like air and water pollution. Nuclear energy harnesses energy from uranium fission but produces radioactive waste that remains dangerous for thousands of years.
Non-renewable energy sources like oil, gas, and coal were formed from the remains of ancient organisms over millions of years. Nuclear fuel comes from uranium ore found naturally underground. Renewable sources harness ongoing natural processes: waves and tides use ocean motion; geothermal and biomass use heat from the Earth's interior and from organic matter; hydroelectricity uses flowing water; solar panels capture the sun's energy; and wind turbines are turned by wind formed by uneven solar heating. These renewable sources provide sustainable alternatives to non-renewable fossil fuels and nuclear power.
This document discusses how electricity has traditionally been generated from fossil fuels like coal, oil, and natural gas by burning them to produce heat that creates steam to power turbines.

The document discusses different sources of energy, including fossil fuels. It explains that there are two main types of energy sources: renewable sources that do not run out like sunlight and wind, and non-renewable fossil fuels like coal, natural gas, and petroleum that are formed from ancient living organisms but will eventually be depleted. These fossil fuels are the primary sources of energy currently used worldwide. While fossil fuels are easy to extract and generate large amounts of electricity efficiently, they also emit air and water pollution and contribute to climate change when burned.
The document discusses different types of energy resources. It defines energy as the ability to produce change or do work. Energy resources are divided into nonrenewable and renewable categories. Nonrenewable resources include fossil fuels like coal, oil, and natural gas. These are formed from the remains of ancient plants and animals. While nonrenewable resources allow for large-scale electricity production cheaply and ease of transport, their main disadvantage is pollution through carbon dioxide and sulfur dioxide emissions, contributing to issues like global warming and acid rain.
Fossil fuels are a nonrenewable energy resource formed from ancient organic matter over millions of years underground. The three main types are coal, petroleum, and natural gas. Coal was historically the primary energy source but is now mainly used for electricity generation. Petroleum provides liquid fuels like gasoline. Natural gas is used for heating and electricity production. However, burning fossil fuels contributes to air and water pollution and greenhouse gas emissions.
Energy comes from sources like fossil fuels such as coal, oil, and natural gas, which were formed from decaying plants and animals millions of years ago. While the Philippines has some coal and oil reserves, they are not sufficient to meet the country's growing energy demands, resulting in reliance on imports. Coal reserves in the Philippines are mostly low-rank lignite coal. Crude oil is found primarily in Palawan and is refined into products like gasoline and diesel. The Philippines also has natural gas reserves, with the largest field being the Malampaya gas field off Palawan, which supplies gas to power plants via a 504 km pipeline. However, the country still relies on other nations for much of its crude oil supply
Fossil fuels such as coal, oil, and natural gas were formed from the remains of ancient plants and animals over millions of years. Coal forms from compressed plant matter, oil forms from the remains of marine organisms, and natural gas forms from ancient microorganisms and organic matter subjected to heat and pressure underground. These fossil fuels are non-renewable and produce carbon dioxide emissions, but they are widely used as energy sources, such as for generating electricity with coal, powering vehicles with gasoline from oil, and producing materials like steel and glass with natural gas. Major oil spills like the Exxon Valdez and Deepwater Horizon catastrophes cause environmental damage by spreading oil across ecosystems.
Nonrenewable resources such as minerals and fossil fuels cannot be replaced at the same rate at which they are consumed. They are finite resources formed over long geological periods. Renewable resources such as solar, wind, and hydropower can be replenished naturally in a short period of time through natural processes like the sun's heat and the wind. The key difference between nonrenewable and renewable resources is that nonrenewables are depleted once extracted while renewables can be replenished within our lifetimes through natural cycles.
1. The sun is the ultimate source of energy on Earth, providing energy that plants store and make available to consumers through photosynthesis.
2. Traditional energy sources include wood, field crops, and animal waste which were burned directly or used to produce heat and energy.
3. Fossil fuels like peat, coal, petroleum, and natural gas formed over long periods of time from the decomposition and compression of decayed plant and animal matter deep underground under heat and pressure.
Fossil fuels are fuels formed by natural processes such as the decomposition of dead organisms over millions of years. They include coal, petroleum, and natural gas and contain high percentages of carbon. The theory that fossil fuels are formed from fossilized remains of dead plants through exposure to heat and pressure in the Earth's crust over millions of years was first introduced in the 16th century.

It also covers renewable energy sources like nuclear power, wind energy, and hydroelectric power. Oil and coal are fossil fuels formed from ancient marine life millions of years ago. Uranium is mined for nuclear fuel and weapons. Nuclear power creates electricity through controlled fission, while wind turbines and hydroelectric dams convert kinetic energy from the wind and moving water into electricity.
The 9.0 magnitude earthquake that struck Japan on March 11, 2011 was the fifth largest recorded worldwide since 1900. Centered 130 km off the coast of Sendai, it generated a massive tsunami that caused widespread damage and over 15,000 deaths. The earthquake and tsunami also triggered a nuclear disaster at the Fukushima Daiichi power plant, resulting in radiation releases and large evacuations due to partial nuclear meltdowns. International relief efforts and donations were mobilized to aid survivors.
The document summarizes information about the Romsdalen Valley in Norway. It is a 60-kilometer long V-shaped valley that runs through two counties. The Rauma River flows through the bottom of the valley and eventually empties into Romsdalsfjorden. Large debris and material regularly flow down the river, making it ideal for white water rafting. This is caused by rocks falling from the steep valley sides due to weathering and freeze-thaw cycles that cause cracking and crumbling of the cliff faces.
Milton Friedman was an influential American economist who taught at the University of Chicago for over 30 years. He received the Nobel Memorial Prize in Economics in 1976 for his research and work on consumption analysis, monetary history and theory, and stabilization policy. Friedman was the main proponent of monetarism and argued that inflation is primarily caused by increases in the money supply. He advocated for limited government intervention in the economy and a restricted role for fiscal policy.

Harehills is an inner-city suburb of Leeds located just east of the central business district that remains largely characterized by its original back-to-back terraced housing and high population density. Two-thirds of homes in Harehills are rented from local councils or landlords and have attracted low-income ethnic minority groups due to low housing costs. Measured as one of the most deprived areas in England, Harehills suffers from high unemployment, low economic participation, and poor education levels, with nearly half of adults lacking qualifications and less than a third of students passing GCSE exams.
Buenos Aires is the capital and largest city of Argentina, located on the eastern coast. With a population of around 12.5 million in its metropolitan area, it is the 10th largest city in the world and one third of Argentina's population lives there. Buenos Aires was established in 1580 by Spanish colonists and grew rapidly in the 19th century with immigrants mainly from France and Spain. Today, the city center contains landmarks like the Plaza de Mayo with cathedral, town hall and presidential palace, laid out in a grid pattern like many American cities. The quality of suburbs declines moving north to south and the periphery contains squatter settlements known as 'Villas miserias' that house the poorest groups, including migrants

2. FINITE AND NON-RENEWABLE ENERGY SOURCES
For several centuries now, non-renewable and finite energy
sources have been our main supply of energy. A non-
renewable resource is a resource that does not renew itself at
a sufficient rate for sustainable economic extraction. In simple
terms, it is an energy resource that is running out faster than
more is being created.
3. COAL PRODUCTION
Coal is a black sedimentary rock. Coal is highly valued for its energy content,
and, since the 1880s, has been widely used to generate electricity. At various
times in way back in the past, the Earth had very dense forests in low-lying
wetland areas. Due to natural processes such as flooding, these forests were
buried underneath soil. As more and more soil built up on top of them, they
were compressed. The temperature also rose as they sank deeper and
deeper. As the process continued the plant matter was protected from rotting
oxidation, usually by mud or acidic water. Under high pressure and high
temperature, dead vegetation was slowly converted to coal. As coal contains
mainly carbon, the conversion of dead vegetation into coal is called
carbonization.
4. COAL PRODUCTION
Coal has been mined for hundreds of years. During Britain's industrial revolution,
there were hundreds of coal mines up and down the country. They were
considered extremely dangerous and many children worked in them. Now
only a handful of mines still operate in the UK. More modern technology and
machinery is used to mine coal, mainly in countries such as China.
5. OIL PRODUCTION
Oil is a viscous liquid derived from petroleum, especially for use as a fuel or
lubricant. Oils have a high carbon and hydrogen content and are usually
flammable and slippery. The oil that is important for energy is crude oil, often
referred to as Petroleum. Crude oil is a yellow to black liquid found
underneath the Earths surface. Like coal, oil is a fossil fuel. Petroleum is a
fossil fuel made from ancient fossilized organic materials, such as
zooplankton and algae. These died thousands of years ago, sinking to lake
bottoms and sea beds, mixing with sediments and being buried. As further
layers settled to the sea or lake bed, intense heat and pressure build up on
the deeper layers. This process caused the organic matter to change into
gaseous hydrocarbons
6. OIL PRODUCTION
Crude oil is often extracted by oil rigs in the sea. They run pipes far
beneath the sea bed, and use huge pumps to extract crude oil. The
North Sea is a very popular area for oil rigs, as there are large oil
reservoirs. Oil is also extracted on land by pumpjacks. These are
often located in desert areas, and are found commonly in the USA.
There are many pumpjacks in Texas.
7. NATURAL GAS PRODUCTION
Natural gas is flammable gas, consisting largely of methane and other
hydrocarbons, occurring naturally underground and can be used as
fuel. It is a fossil fuel formed when layers of buried plants, gases, and
animals are exposed to intense heat and pressure over thousands of
years. The energy that the plants originally obtained from the sun is
stored in the form of chemical bonds in natural gas. Natural gas is a
non-renewable resource because it cannot be replenished on a
human time frame.
8. NATURAL GAS PRODUCTION
Extracting natural gas is very much like the extraction of oil. Large gas reserves
are found below the ground, and pipes are sent down to extract the gas. Gas
extraction is very dangerous, as gas is extremely volatile and flammable. This
can lead to disasters, so any extraction must be managed very carefully.
9. NUCLEAR ENERGY
Nuclear energy is the energy released during nuclear fission or fusion,
especially when used to generate electricity. Nuclear power plants
convert the energy released from the nucleus of an atom via nuclear
fission that takes place in a nuclear reactor. Nuclear fission is the
splitting of the atom. The heat is removed from the reactor core by a
cooling system. This cooling system uses the heat to generate
steam, which drives a steam turbine connected to a generator
producing electricity.
10. NUCLEAR ENERGY
The process of harbouring nuclear energy is one of extreme danger. Uranium
used in the process is extremely volatile, and if not cooled correctly can melt
through all metals and solid concrete. If a nuclear reactor is exposed,
radiation will emit outwards over a huge area. This can be seen in the city of
Pripyat, Ukraine. The 1986 Chernobyl Disaster meant the city was
abandoned in a day, anyone left behind would die of exposure. A 20 km
exclusion zone is still active, as this radiation will take millions of years to
fade.
11. RENEWABLE ENERGY SOURCES
Renewable energy is generally defined as energy that comes from
resources which are naturally replenished on a human timescale. In
the modern day, we are turning more and more towards the use of
renewable energy sources. They can be replenished unlike fossil
fuels, and also pose little threat to the environment. Renewable
energy sources are sustainable.
Sustainable – ‘Using resources in the present day
without damaging the needs and wants of future
generations’.
12. GEOTHERMAL ENERGY
Geothermal energy is thermal energy generated and stored in the Earth.
Geothermal power stations run large pipes far down below the Earths
crust. The deeper they run, the hotter the Earth becomes. Water is sent
down these pipes and turns to steam. This steam is then returned to the
surface where it turns a turbine attached to a generator, creating
electricity. Geothermal power stations can only be operated in certain
locations due to the depth the pipes need to reach. They are well known
for being widely used in Iceland.
13. WIND ENERGY
Wind turbines are used to turn wind energy into electricity. They can be
found singularly, but are usually together in wind farms. The wind
turns the turbine, which is attached to a generator, producing
electricity. Some people do argue that wind turbines mar a
landscape, and also that they can be damaging to wildlife,
particularly birds.
14. SOLAR ENERGY
The sun is can be used as a great source of energy. Energy from
sunlight is captured in solar panels and these panels convert it into
energy. Solar panels are becoming increasingly popular, and can
easily be fitted onto house roofs. They are sometimes costly to
produce, but do make the money back in with their energy producing
abilities.
15. TIDAL ENERGY
Tidal energy production uses the movement of tides to drive turbines. A
tidal barrage is built across estuaries, forcing water through gaps.
These gaps allow high pressure water through, turning turbines. In
the future underwater turbines may be possible out at sea and
without dams. This would mean that ships could travel over them
with no effect.
