Energy Concepts and Consumption

Energy Consumption

Measured in terawatt-hours, including losses from inefficiencies in energy production.

TWH

Terawatt-hour, a measure of energy, particularly in the context of consumption.

Work

Application of force over a distance, measured in joules.

Power

Rate of energy flow, measured in watts.

Joule (J)

Unit of work or energy in the International System of Units.

Megawatt (MW)

Unit of power equal to one million watts.

Biofuels

Renewable energy sources derived from biological materials.

Anthracite Coal

A type of coal with the highest carbon content and fewest volatile compounds.

Coal Ash

Waste product from coal combustion, containing toxic substances.

Fracking

Hydraulic fracturing process used to extract oil and natural gas.

Renewable Energy

Energy from sources that are replenished naturally, like solar and wind.

Nuclear Energy

Energy produced through nuclear fission, generating significant electricity.

Natural Gas

Fossil fuel primarily composed of methane, found with coal deposits.

Uranium

Key element for nuclear energy, with isotopes such as U-235 used in reactors.

Efficiency of Work

Ratio of useful work output to total energy input.

Tar Sands

Deposits of sand and clay containing crude bitumen, a type of oil.

Peak Oil

The point in time when the maximum rate of extraction of petroleum is reached.

Cooling Tower

Structure used to dissipate heat from circulating water in industrial processes.

Steam Turbine

Mechanical device that converts steam energy into mechanical work.

Control Rods

Devices used in nuclear reactors to manage the fission process.

Gamma Rays

High-energy electromagnetic radiation emitted during nuclear reactions.

Thorium

Element more abundant than uranium and a potential alternative for nuclear fuel.

Carboniferous Period

Geological period during which coal deposits were formed.

Methane Hydrates

Ice-like structures trapping methane, found under ocean floors and in permafrost.

Electricity Grid

Network of transmission lines and substations for distributing electrical power.
