Major Sources of Enegry

Entails the different sources of energy, advantages, and disadvantages of the different sources of energy, The importance of renewable and non renewable sources of Energy, The process in which photovoltaic cells are used, and how solar water heaters work.

Biomass Energy

Refers to energy obtained from organic matter, mainly referring to plants, wood and other agricultural waste. Considered a renewable form of energy and can be converted into biofuels, electricity, or heat.

Geothermal Energy

Refers to Energy obtained from natural heat kept underground or beneath the earth’s surface, making it carbon free. Natural Geysers, and Hot springs are examples of Geothermal Energy.

Non- Renewable Energy

Refers to energy that cannot be replenished naturally within a lifetime when used up. Nuclear and Fossil fuel energy are examples of Non-Renewable Energy.

Renewable Energy

Refers to energy that can be naturally replenished over short periods of time. Solar, Wind, Water, Waves, Geothermal, and Biomass energy are examples of Renewable Energy.

Chemical Energy

Chemical energy can come from any fuel, referring to the potential energy stored in the bonds between atoms and molecules. Examples of chemical energy are Food (digestion), and combustion reactions, such as the combustion of wood.

Solar Energy

Refers to energy obtained from nuclear fission in the sun’s core. When extreme heat and pressure fuse hydrogen atoms into helium, releasing massive energy. Capturing this heat to then generate electricity uses Photovoltaic cells which when placed together in a group, these cells form a Solar Pannel.

Potential energy from Water

Refers to the energy stored in water due to its position, such as water held in a dam. This energy can be converted to kinetic energy when the water flows down.

Nuclear Energy

Refers to energy released during nuclear reactions, such as fission or fusion. It is a potent source of energy for electricity generation.

Electricity Generation

The process of converting various energy sources (such as fossil fuels, renewables, or nuclear) into electrical energy for consumption.

Hydroelectric power generation

Involves capturing the energy of flowing water, typically from a river or dam, and converting it into electricity using turbines.

Wind Power Generation

The process of converting kinetic energy from wind into mechanical power, which is then used to generate electricity through wind turbines.

Wave Power Generation

The process of capturing energy from surface waves on the ocean or seas and converting that energy into electricity.

Solar Power Generation

The conversion of sunlight into electricity using photovoltaic cells or solar thermal systems.

The process of Heating, Cooling, and Air Conditioning

The process of regulating indoor temperature and air quality through systems that heat or cool air, often utilizing ventilators, ducts, and thermostats to ensure comfort.

Water Pumping

The process of moving water using mechanical devices, typically to supply water for irrigation, drinking, or other uses.

Photovoltaic Cells

Devices that convert sunlight directly into electricity by utilizing the photovoltaic effect.

How Do Solar Heaters Work?

Solar heaters use sunlight to heat water or air for residential or commercial use, typically involving solar collectors to capture heat.

Flat Plate Collectors

Devices that use a flat surface to absorb solar radiation for heating water, commonly used in solar water heating systems.

Batch Collector and Evacuated tube methods

Batch collectors use a single tank to heat water directly from solar energy, while evacuated tube collectors are designed with glass tubes to enhance absorption and heat retention.
