- 2. NONRENEWABLE RESOURCES A nonrenewable resource is a natural resource that cannot be re-made or re- grown at a scale comparable to its consumption.
- 5. Non Renewable Energy Sources
- 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. WHAT is THE DIFFERENCE BETWEEN COAL AND OIL/GAS?
- 10. WHAT is THE DIFFERENCE BETWEEN COAL AND OIL/GAS? • Basically, coal is purely vegetation in stratam. It is always “longer- chain” hydrocarbons. • Oil may be formed from animal as well as plant decomposition, and has relatively shorter hydrocarbon chains, making it a liquid instead of a solid
- 11. 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.
- 12. NUCLEAR ENERGY Nuclear fission uses uranium to create energy. Nuclear energy is a nonrenewable resource because once the uranium is used, it is gone!
- 13. Nuclear Energy Uses • Nuclear energy is used for Electricity generation. • Nuclear energy can be used in ships. • Can be used for industrial heating • Can be used in aircrafts. Drawbacks • Nuclear plant uses radioactive materials and produce radio active waste which is harmful to human health. • Life of Nuclear plant is only 30-40 years.

- 15. Nonrenewable resources are resources that cannot be re-made at a scale comparable to its consumption, what are renewable resources?
- 16. RENEWABLE RESOURCES Renewable resources are natural resources that can be replenished in a short period of time. Renewable Energy -Energy whose source never runs out. ● Solar ● Geothermal ● Wind ● Biomass ● Water
- 18. Renewable Energy
- 19. SOLAR Energy from the sun. Energy from the sun is renewable
- 20. GEOTHERMAL Energy from Earth’s heat. Energy from the heat of the Earth is renewable.
- 21. WIND Energy from the wind is renewable
- 22. BIOMASS Energy from burning organic or living matter. Why is energy from biomass renewable?
- 23. WATER or HYDROELECTRIC Energy from the flow of water.

- 25. SUMMARY What are the differences between nonrenewable and renewable resources? Renewable resources can be used again and again. Non-Renewable resources have a limited supply and once used cannot be regained
- 26. Renewable and Non Renewable Resources
- 29. Some of the Natural Resources 1) Forest resource 2) Water resource 3) Energy resource 4) Land resource
- 31. Problems Associated with Natural Resources • Unequal consumption of natural resources. • Producing animal food for human consumption requires more land than that required for growing crops. • Natural resources often provide fertile ground for corruption. • Our use of natural resources affects the environment in many ways. • Lack of water is a problem in cities, towns and villages.
