Sustainable Energy (OCR)

Energy Stores

"Ways in which energy can be stored or transformed, such as gravitational potential, kinetic energy, thermal energy, nuclear energy, and chemical energy."

Gravitational Potential

"Energy stored due to an object's position above the Earth's surface, utilized in hydroelectric power generation."

Kinetic Energy

"Energy possessed by a moving object, like in flywheel energy storage systems used in hybrid vehicles."

Thermal Energy

"Energy stored in the form of heat, as in night storage heaters releasing heat from concrete blocks."

Nuclear Energy

"Energy released from the nucleus of an atom, such as in nuclear fission reactions."

Chemical Energy

"Energy stored in the bonds of chemical compounds, released during chemical reactions, as in batteries or fuel in power plants."

Power

"Rate at which energy is transferred or converted, measured in watts (W) or kilowatts (kW)."

Energy Transfer

"Process of transferring energy from one object to another, often through work or heat."

Joule

"Unit of energy in the International System of Units (SI), equivalent to the energy transferred to an object when applying a force of one newton over a distance of one meter."

Kilowatt-hour (kWh)

"Unit of energy equivalent to one kilowatt of power expended for one hour, commonly used to measure electrical energy consumption."

Energy Conservation

"Principle stating that energy cannot be created or destroyed, only transferred or converted between different forms."

Dissipation

"Loss of energy as it is transferred or converted into unusable forms, such as heat or sound."

Thermal Insulation

"Use of materials with low thermal conductivity to reduce the rate of heat transfer between objects or environments."

Thermal Conductivity

"Property of materials determining how quickly heat is conducted through them."

LED Light Bulbs

"Energy-efficient light sources that convert a higher percentage of electrical energy into light compared to traditional incandescent bulbs."

Sound Energy

"Form of energy produced by vibrations that travel through air, water, or other mediums, often considered a form of dissipated energy."

Efficiency

"Measure of how well energy is converted from its source to the desired output, calculated as useful output energy divided by input energy."

Sankey Diagrams

"Visual representation illustrating the flow of energy through a system, with arrows scaled to show energy quantities."

Energy Resources

"Various sources from which energy can be obtained categorized as renewable (e.g., solar, wind) or non-renewable (e.g., fossil fuels, nuclear)."

Renewable Energy

"Energy sources that can be replenished naturally or through human intervention, such as wind, solar, and hydroelectric power."

Non-renewable Energy

"Energy sources that are finite and will eventually be exhausted, such as fossil fuels and nuclear fuels."

Electricity Generation

"Process of producing electrical energy from various sources, often involving generators driven by turbines."

National Grid

"Network of interconnected power stations and transmission lines used to distribute electricity throughout a country or region."

Mains Electricity

"Electricity supplied to homes and businesses through the national grid, typically alternating current (AC) in most countries."

Transformer

"Device used in electrical grids to change the voltage of electricity for efficient transmission and distribution."

Energy Needs

"The diverse requirements for energy in households, industries, transportation, and public services."

Fossil Fuels

"Non-renewable energy sources derived from ancient organic matter, such as coal, oil, and natural gas."

Nuclear Power Plants

"Facilities that generate electricity through nuclear reactions, using uranium or plutonium as fuel."

Greenhouse Effect

"Process by which greenhouse gases trap heat in the Earth's atmosphere, contributing to global warming."

Energy Conservation

"Efforts to reduce energy consumption by increasing efficiency and minimizing waste."

Global Energy Usage

"Patterns and trends in the consumption and production of energy worldwide, influenced by economic, technological, and environmental factors."

Electricity Demand

"Variations in the amount of electricity consumed throughout the day and across seasons”.
