1. Electric Energy: A Comprehensive Overview Electric energy is an essential part of our lives, powering our homes, businesses, and transportation. This presentation will delve into the science, types, and applications of electric energy, exploring its potential and challenges. EM by Erwin Mapalad

2. The Science of Electricity 1 Electric Charges Electricity is the flow of electric charges, primarily electrons. These charges are either positive or negative, and their movement creates an electric current. 2 Electric Fields Charged objects create an electric field around them, exerting forces on other charges. 3 Voltage Voltage is the potential difference between two points in an electric field, driving the flow of electric current. 4 Current Electric current is the rate of flow of electric charge, measured in amperes (A).

3. Types of Electric Energy Direct Current (DC) DC flows in one direction and is commonly found in batteries and electronic devices. Alternating Current (AC) AC reverses direction periodically and is the standard for household and industrial power. Static Electricity Static electricity refers to an imbalance of electric charges on a surface, often resulting in a sudden discharge.

4. Renewable vs. Non-Renewable Sources Source Renewable Non-renewable Definition Naturally replenished over time Limited supply, eventually depleted Examples Solar, wind, hydro Fossil fuels (coal, oil, natural gas), nuclear Environmental Impact Generally lower emissions Significant pollution and greenhouse gas emissions

5. Advantages and Disadvantages of Electric Energy Advantages Versatile, efficient, clean (with renewable sources), and can be generated in many locations. Disadvantages Can be costly to produce, transmission losses, environmental impact of non-renewable sources, and potential for accidents in power plants.

6. Electricity Generation and Distribution Generation Electric energy is generated from various sources, such as fossil fuels, nuclear power, hydro, solar, and wind. Transmission High-voltage transmission lines carry electricity from power plants to substations. Distribution Substations reduce voltage and distribute electricity to homes, businesses, and industries.

7. Energy Storage and Conservation 1 Batteries Store energy chemically, used in electric vehicles and grid-scale storage. 2 Pumped Hydro Stores energy by pumping water uphill and releasing it to generate electricity. 3 Energy Conservation Reducing energy consumption through efficient appliances, lighting, and building design.

8. The Future of Electric Energy Renewable Growth Expanding renewable energy sources to reduce reliance on fossil fuels. Smart Grid Technologies Using advanced technologies to manage and optimize energy flow. Electric Vehicles Increasing adoption of electric vehicles to reduce transportation emissions. Energy Efficiency Continued focus on reducing energy consumption and improving efficiency across all sectors.
