PRODUCING ELECTRICITY FROM FOSSIL FUELS
- 1. SUBMITTED BY : GUIDED BY SUBMITTED TO :- VIVEK VISHWAKARMA MISS. AMRITA SRIVASTAVA Dr. SANJAY KUMAR SRIVASTAVA M.Sc Previous H.O.D Physics Department K N I P S S SULTANPUR
- 3. Fossil Fuel
- 4. These fuels were dug out of the ground. They had taken millions of yea rs to make and so are called FOSSIL FUELS and are NON-RENEWA BLE. COAL Made from the remains of plants which died millions of years ago
- 5. OIL and NATURAL GAS (Methane) Made from the decayed remains of sea creatures which died millions of years ago
- 6. Generating Electricity For many years, we have generated electricity in much the same way:
- 7. All these fossil fuels are running out and burning them increases carbon dioxide in the atmosphere which increases the GREENHOUSE EFFECT, causing GLO BAL WARMING. Some fossil fuels contain SULPHUR and when they burn t his becomes SULPHUR DIOXIDE, a poisonous gas whic h reacts with water in the atmosphere to form SULPHURI C ACID or ACID RAIN.
- 8. To solve the problems of fossil fuels, we need to devel op: RENEWABLE FUELS: •Biomass •Wind Energy •Tidal Energy •Solar Energy •Geothermal
- 10. Wind Energy
- 12. Special versions of this can be used to produce energy quickly on demand.
- 13. Tidal Power.
- 14. Wave Power 1.
- 15. Wave Power 2
- 16. Solar energy
- 17. Solar energy
- 18. Geothermal In certain parts of the world, heat from the Earth can be used t o produce steam to power turbines and heat homes.
- 19. Fossil Fuel Strengths The current power generation and distribution model operates on fossil f uels, and has for centuries if you consider coal. Fossil fuel essentially is p ortable energy. A company easily stores and transports the energy until it needs to be used Fossil Fuel Weaknesses One primary weakness of fossil fuels relate to their chemical makeup. As operations burn the fuel, they release hydrocarbons that mix with th e atmosphere and produce greenhouse gases like carbon dioxide or poll ution, including sulphur dioxide--a source of acid rain
- 20. Renewable Energy Strengths The primary advantage to renewable energy is in its production source: sun and gravitational pull yield solar, wind and wave en ergy; Renewable Energy Weaknesses Renewable energy sources harness or replicate nature’s processe s in its production, so it shares some of the weaknesses. Wind m ills and solar panels take large tracts of space to collect energy, a s the energy is diluted across the environment
- 21. To make sure we have plenty of energy in the future, it's up to all of us to use energy wisely. We must all conserve energy and use it efficiently. It's also up to those who will create the new energy technologies of the future. All energy sources have an impact on the environment. Concerns abou t the greenhouse effect and global warming, air pollution, and energy s ecurity have led to increasing interest and more development in renew able energy sources such as solar, wind, geothermal, wave power and hydrogen. But we'll need to continue to use fossil fuels and nuclear energy until n ew, cleaner technologies can replace them. One of you who is reading this might be another Albert Einstein or Marie Curie and find a new so urce of energy. Until then, it's up to all of us. The future is ours, but we need energy to get there.

- Fossil Fuel.....What are fossil fuels? Petrol, Diesel....On which most of our transportation depends, Coal , Gas ....used in cooking....all are fossil fuel. These are formed by natural processes . Gradual decomposition of organic matter under sedimentary rocks, followed by its anaerobic decomposition over a period of time (in millions of year) under high pressure and temperature leads to the formation of Fossil Fuel. Carbon is its major component.
- It is the Agricultural and Animal Waste Can be used in production of Biogas, a comparatively clean fuel and the residue acts as an excellent fertilizer . Quick-growing plants can be burnt in power stations instead of fossil fuels but plants can also be grown to produce oils or sugars to make alcohol which can be used as a fuel like petrol.
- Wind power is the use of air flow through wind turbines to mechanically power generators for electricity. Wind power, as an alternative to burning fossil fuels, is plentiful, renewable, widely distributed, clean, produces no greenhouse gas emissions during operation, consumes no water, and uses little land. The net effects on the environment are far less problematic than those of non renewable power sources.
- These use the Gravitational Potential Energy of water on hills as it flows downhill moving a turbine which in turn generates Electricity
- First figure shows the view above the water level and second one shows the inside view of the ocean. Its nodding motion causes the rotation of turbine.......further generating electricity....
- Solar power is the conversion of sunlight into electricity, either directly using photo voltaics (PV), or indirectly using concentrated solar power. Concentrated solar power systems (Unified Solar) use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photo voltaics convert light into an electric current using the photovoltaic effect.
- Geothermal Energy is the heat from the Earth... Clean and sustainable.... Resources: range from the shallow ground to hot water and hot rock found a few miles beneath the earth surface and down even deeper to the extremely high temperature of molten magma. Again it is used to rotate the turbine....
