A non-renewable energy source derived from ancient plants and animals. Examples: coal, oil, natural gas.
Bio-fuels
A renewable energy source produced from organic matter. Can generate electricity or power vehicles. Examples: ethanol from plants, agricultural waste.
Geothermal
A renewable energy source harnessing heat from the Earth's interior to generate electricity. Hot water or steam is tapped from underground reservoirs.
Solar Energy
A renewable energy source that uses photovoltaic cells (PVs) to convert sunlight into electricity. Solar panels generate electricity.
Carbon Monoxide
A toxic gas produced by the incomplete combustion of fossil fuels, deadly in high concentrations
Carbon Dioxide
A natural part of the Earth's atmosphere, released during the burning of fossil fuels and bio-fuels, major contributor to climate change and global warming
Fossils - Remains
Focuses on the physical matter left behind after death or decay
Fossils - Bio
Refers to the biological origins of the fuel or the presence of living organisms
Burning Bio-Fuels
Burning fuels produced from organic matter, like plants, animals, or microorganisms. Examples: ethanol from corn or sugarcane, biodiesel from soybeans or sunflowers.
Burning Fossil Fuels
Burning fuels formed from ancient plants and animals that have been buried for millions of years. Examples: coal, oil, and natural gas.
Carbon Neutral
A process that releases the same amount of carbon dioxide into the atmosphere as the amount absorbed by the crops during their growth.
Convection
The transfer of heat through a moving liquid or gas due to density differences.
Conduction
Heat transfer through direct physical contact
Convection
Heat transfer through the movement of fluids (air, water, etc.)
Radiation
Heat transfer through electromagnetic waves (infrared, visible, ultraviolet, etc.) without physical contact
