Renewable resources are natural resources that can replenish themselves over time, making them sustainable despite human consumption. They are considered vital for their potential to replace non-renewable resources in energy production and offer cleaner energy solutions compared to fossil fuels like coal1. Here’s a brief description of renewable resources: Renewable resources are those that are naturally replenished on a human timescale. They are virtually inexhaustible and include sources like the sun, wind, water, geothermal heat, and biomass. These resources are crucial as they can generate energy that is sustainable and lessens the strain on finite fossil fuels1. Some key points about renewable resources: They provide a continuous source of clean energy. They are essential for long-term sustainability. They include biomass, hydropower, geothermal power, wind energy, and solar energy. Biomass comes from organic material like wood, sewage, and ethanol. Hydropower uses flowing water to generate electricity. Geothermal energy harnesses heat from Earth’s core. Wind energy is produced by turning wind turbines. Solar energy is derived from the sun’s radiation2. The demand for renewable resources is increasing as they are seen as a solution to the growing concerns over energy sustainability and environmental impact

geothermal, hydroelectric and bioenergy
technologies and explore potential solutions
to these challenges.
● Overall, the advances in renewable energy
hold great promise for a cleaner, more
sustainable, and more secure energy future

5. Natural Resources
The Materials occurring in nature which are used to support
life and people’s needs are known as Natural Resources
● Forest. ● Wind energy
● Solar energy ● Fossil Fuels

6. Non Renewable Resources
• Fossil fuel like oil , coal , petrol
• Forest
• Minerals
Non Renewable
Resources
●The Natural Resources that are consumed in large
quantities but takes more time to Regrow.
●They can’t be remade as quickly as people need it
●They also harm our environments and are the
main cause of pollution.

7. RenewableResources
● Natural Resources that even after consuming a
lot, has no effect on the supply of these Resources
● These are never ending or Regrow very quickly
and eco-friendly too! Such as
▪︎ Solar Energy ▪︎ Wind Energy ▪︎Hydro(water)
▪︎ Biomass. ▪︎ Geo-Thermal

8. ●To know the Renewable Resources
●To know the Side effects of Non
Renewable Resources & Solutions
●To know about recent Inventions and
advances in Renewable Energy.
● Measures to be taken to save earth
Main Objectives :

9. SolarEnergy
● Solar Energy is derived by capturing radiant
energy from sunlight converting into Heat ,
electricity , hot water.
● The photovoltaic systems convert the sunlight
directly into Electrical energy through photo
cells inbuilt in the panels
●These panels absorb the light and stores in the
form of energy

10. ●Sunlight is functionally
endless, So there is
limitless supply of the
energy.
●Hence it can be easily
replaced with fossil fuels
●Also builds good
environmental conditions
and improves public health.
● The panels cost high
and are very expensive
●It occupies a lot of
space and requires very
high maintenance
●No energy will be
generated at nights &
cloudy days. Less in the
winter & rainy seasons

12. WindEnergy
Advances in wind turbine have led to the
development of efficient turbines.
Additionally, innovations in blade design
& materials have increased the efficiency
of wind turbines. Longer blades on wind
turbines can capture more energy, leading
to increased electricity generation.

13. ● Researchers are exploring
the use of materials such as
carbon fibber to make wind
turbines lighter and more
efficient

14. HydroElectricenergy
Advances in hydropower technology have
led to the development of more efficient
turbines, which generate more electricity.
The use of pumped storage hydropower
has also increased, allowing excess energy
to be stored for use when demand is high.

15. A hydropower system, uses a dam to store
river water in a reservoir. Water released
from reservoir flows through a turbine,
spinning it, which in turn activates a
generator to produce electricity

16. Biomass
Bioenergy involves using organic matter, to
generate electricity/heat. Advanced technologies
include anaerobic digestion, which converts
organic waste into biogas. Advances in biomass
technology have led to the development of more
efficient biomass stoves and boilers, which use
wood, agricultural waste, and other materials to
generate heat and electricity.

17. Natural Gas
Geothermal energy harnesses heat from
earth’s interior to generate electricity/heat.
Advanced geothermal technologies include
enhanced geothermal systems, which involve
injecting the water into hot rock formations
to create steam that can be used to generate
electricity. This has led to the development of
more efficient geothermal power plants.
Geo-thermal Energy

19. Conclusion:
●Finally, advances in regulation have played a critical
role in growth of renewable energy. Many countries
have introduced incentives & regulations that have
encouraged in adoption of renewable energy
●Overall, the Advances in renewable energy have
made it a viable & attractive option for meeting the
world’s energy needs, while reducing greenhouse
gas emissions and addressing climate change.

20. ●A major contributor to the world’s energy.
●Advances in renewable energy have made it
more cost-effective and efficient.
●One of the most notable inventions is the
continued reduction in the cost of solar
