Fossil fuels take millions of years to form., coal - made from decayed swamp plants + millions of years of heat and pressure, oil and natural gas - heat and pressure applied for millions of YEARS to microscopic marine organisms create pockets of oil and natural gas, alternative energy sources - Energy, such as solar, wind, or hydroelectric, that can replace or supplement fossil-fuel sources, as coal, oil, and natural gas. , wind energy - A form of energy in which turbines convert the kinetic energy of wind into mechanical or electrical energy., solar energy - Energy from the Sun's radiation that is collected on special panels and converted into electrical energy., hydroelectric energy - The kinetic energy from water falling over a dam that is captured and converted into electrical energy., geothermal energy - Obtained by tapping underground reservoirs of heat, usually near volcanoes. Steamy hot springs and geysers come from these same heat sources., biofuels - Plants such as corn, are grown and converted into fuel for energy., pollution - The introduction of harmful and deadly substances or products into the environment., conservation - Protect and preserve the Earth's natural resources with 3 practices: Reduce, Reuse, Recycle,
