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.

2. NATURAL RESOURCES
• Materials or substances occurring in nature which can be exploited for economic
gain.
• Energy is related to power.
• Energy are classified into two
* Renewable Energy
* Non-renewable Energy
• Energy can have many forms: kinetic, potential, light, sound, gravitational,
elastic, electromagnetic or nuclear.
• It leads to large amount of destruction of natural landscapes and habitants
through the process of fuel extraction, pollution of soil, climate change.
• Since the Industrial Revolution, which began in around 1760, the majority of
this energy has come from energy rich resource known as fossil fuels.
ENERGY

4. RENEWABLE RESOURCES
• Sources of power that quickly replenish naturally themselves in the course of time
and can be used again and again are called Renewable Resources.
• Renewable sources can be used to generate electricity , heat or sometimes both.
• They generate clean energy which does not release greenhouse gas emissions
in the process.
• Produced from natural sources like sun, wind, rain, tides
• Available in plenty and far most the cleanest sources of energy available on this
planet
• Renewable technologies are suited to
large-scale production
small off grid applications

5. • Main forms of renewable energy
*Wind energy (stronger and more constant)
*Hydro energy (for large scale hydroelectric dams)
*Solar energy (naturally circulate the air)
*Bio-fuel (bio-ethanol or bio-diesel)
*Geothermal energy (2 types of geothermal energy deposits)
1.hydro - geothermal energy resources
2.petro – geothermal energy deposits
ADVANTAGES
• Won’t run out and can be used again and again.
• Produce clean energy that does not pollute the environment or contribute to
climate change.
• Renewable energy facilities generally require less maintenance than traditional
fossil fuel generators.
• Renewable energy is derived from natural and available resources.

6. • This reduces the costs of production, as the resources used to produce the energy
often don’t need to be purchased or can be obtained more cheaply and easily than
fossil fuels
DISADVANTAGES
• Currently difficult to generate quantities of energy as large as those produced by
traditional fossil fuel generators.
• This may mean we need to reduce the amount of energy we use or to develop
more energy facilities.
• Often rely on the weather to provide power.
• Hydro generators need rain to fill dams to supply flowing water. Wind turbine
needs wind to turn the blades and solar panels need clear skies and sunshine to
collect heat and make electricity.
• When these resources are unavailable, so is the capacity to make energy from
them. This can be unpredictable and inconsistent.

7. NON-RENEWABLE RESOURCES
• Resources that exist in limited supply and cannot be remade or regrown at a scale
comparable to its consumption are called Non- renewable resources.
• Burning fossil fuels also produces greenhouse gases and are the main cause of
man-made climate change.
• Termed as Stock resources
• They are present in all three states like solids, liquid and gases
 Solid form of non-renewable resources – Coal, ignite, minerals etc.
 Liquid form of Non-renewable resources- Petroleum
 Gaseous form of Non-renewable resources – Natural gas

8. Types of Non-renewable resources
* Nuclear energy (uranium)
*fossil fuels like
coal (when burnt causes global warming)
petroleum (flammable liquid)
oil (crude oil)
natural gas (contains methane, ethane, propane, butane)

9. • NATURAL GAS
The formation of natural gas is a long-term process as decomposition is conducted by
a high amount of pressure and heat which takes billions of years.
• COAL
Coal is formed by decomposition of trees, plants and ferns which is a time taking
process.
• OIL
Small organisms like zooplankton and algae are decomposed into oil due to exessive
pressure.

10. ADVANTAGES
• Ready-made fuels.
• Resources like coal and oil provides more energy than the renewable resources such as solar and wind.
• Huge profit can be generated in the mining of coal, selling of oil or the construction of natural gas
pipelines.
• They give a large amount of energy from a small amount of fuel.
• Relatively cheap to extract and convert to energy.
• Readily available and reliable.
• If you need more energy, you just burn more fuel
• Their availability is not affected by climatic condition.

11. • DISADVANTGES
• They are non-renewable. Once you burn them, they can be utilized again.
• Burning a fossil fuel emits carbon dioxide, it rapidly destroys ozone layer.
• Burning a fossil fuel can produce sulphur dioxide and smoke, which converts rain
into acid rain.
• Non-renewable energy can be dangerous and cause respiratory problems to humans
because fossil fuels emits carbon monoxide.

12. STEPS TO BE TAKEN FOR CONSERVATION OF NATURAL RESOURCES
• Use various resources only when needed
• Avoid the wastage of resources
• Avoid the use of materials from wild life sources.
• Use energy efficient electrical appliances.
• Using of pressure cookers saves 75% of LPG
• Minimize the use of old vehicles as they are less fuel-efficient and causes pollution.
• Utilizing renewable resources
• Recycling of waste and waste water for agricultural resources.
