The energy
- 1. The Energy “ If you want to find the secrets of the universe, Think in terms of Energy, Frequency and, Vibration ” Nikola Tesla Presented by Shady AlGendy
- 2. What is Energy ? • The Simplest definition of energy is "the ability to do work". • There are two types of energy: • Stored (potential) energy. • Working (kinetic) energy. • Energy is a conserved quantity the law of conservation of energy states that energy can be converted in form such as (Electrical, Chemical, Nuclear, Thermal, Radiant ), but not created or destroyed.
- 3. Different types of energy According to sustainability Non-renewable It’s getting real Renewable Energy It’s already happening
- 4. Natural gas used as a source of energy for heating, cooking, electricity generation, fuel for vehicles, plastics and organic chemicals Nuclear splitting atoms in a reactor to heat water into steam Coal produce electricity by burning coal in a boiler to produce steam Oil burned under pressure to produce hot exhaust gases Non-renewable Energy
- 5. Nuclear Energy Advantages and Disadvantages Advantages Disadvantages • Relatively Low Costs. • Low Pollution. • High Energy Density. • Accidents Happen. • Radioactive Waste. Sustainable? • nuclear energy is not a renewable energy source. there is a limited amount of fuel for nuclear power available. On the other hand, you could argue that nuclear energy is potentially sustainable by the use of breeder reactors and fusion reactors.
- 6. Oil, Natural gas, Coal Advantages and Disadvantages How Oil and Natural Gas are Made? Advantages • Deep in the Earth, oil and natural gas are formed from organic matter from dead plants and animals. These hydrocarbons take millions of years to form under very specific pressure and temperature conditions. • We can prepare non-renewable supplies at almost any location. • produce more power (Combined cycle). • Cheaper than renewable sources. • provide us with many products. Disadvantages • lead to high levels of pollution (Carbon Dioxide). • not be available forever. • direct impact on government structures. • dangerous to human health, plant and animal life.
- 7. Hydro Energy The water cycle is constantly renewed by the sun Solar Energy The cleanest and most abundant renewable energy source availableGeothermal energy heat energy from within Earth is captured and harnessed for cooking, bathing and generate electric energy Wind Energy Wind is used to generate mechanical power or electricity. Renewable Energy
- 8. Renewable energy Advantages and Disadvantages Advantages Disadvantages • Renewable energy won’t run out. • Maintenance requirements are lower. • They don’t damage our planet. • Higher upfront cost. • Low-efficiency levels. • Unreliable ( weather can affect energy supply ). • Many forms of renewable energy require storage capabilities.

- 11. Is there a free energy generator ? A lot of YouTube videos gain millions of views by changing the coils in the stator and the rotor with permanent magnets And start moving the rotor by their hand then the generator Continues to spin and feeding a small load such as a lamb. The truth is this kinetic energy can only last minutes Depending on the size of the permanent magnets And can not feed a large load so you only find these videos Do not exceed minutes.
