Unit 5 Vocabulary 11/13/12 S: Which energy transformation produces electricity with the LEAST negative environmental impact: coal, solar, oil.
P: Vocabulary Notes Energy Resources – anything that can be used as a source of energy to do work.
Energy Conservation – management of energy use through insulation, increasing energy frequency, and changes in patterns of use.
Did you know there are at least 12 energy sources? Petroleum Propane Natural Gas Hydroelectric Hydrogen Biomass Ethanol Solar Coal Geothermal Wind Nuclear
Each energy source is either renewable or nonrenewable! ENERGY SOURCES OF THE WORLD! NONRENEWABLE RENEWABLE
Renewable Energy Sources ENERGY SOURCES OF Renewable resources canbe replenished. Energy sources like hydroelectric power, solar energy, and wind power. THE WORLD! RENEWABLE
Nonrenewable Energy Sources ENERGY SOURCES OF Nonrenewable resources take millions of years to form and cannot be regenerated in a short period of time. THE WORLD! NONRENEWABLE
PETROLEUM PETROLEUM is formed from animals and plants that lived millions of years ago when heat and pressure turned decayed matter into crude oil. nonrenewable
PROPANE PROPANE is produced as a byproduct from natural gas processing and crude oil refining. It burns hotter and more evenly than other fuels. nonrenewable
NATURAL GAS NATURAL GAS consists primarily of methane but includes significant quantities of ethane, butane, propane, carbon dioxide, nitrogen, helium, and hydrogen sulfide. nonrenewable
COAL COAL is formed from trees and plants in vast primeval forests, when heat and pressure turned decayed matter into coal. Coal is a part of the fossil fuels family. nonrenewable
NUCLEAR ENERGY NUCLEAR ENERGY is generated in reactors, when nuclear fuel fission heats water, and the steam turns turbines to run the generators that convert energy into electricity. nonrenewable
SOLAR ENERGY SOLAR ENERGY is generated when photovoltaic (PV) cells convert heat from the sun directly into electricity. renewable
HYDROELECTRIC HYDROELECTRIC POWER is generated when flowing water turns turbines to run generators that convert energy into electricity. renewable
WIND POWER WIND POWER is generated when wind turns turbines to run the generators that convert energy into electricity, which is then stored in batteries. renewable
BIOMASS BIOMASS is produced from vegetable oils, animal fats, recycled restaurant greases, and other byproducts of plant, agricultural, and forestry processing or industrial and human waste products. renewable
ETHANOL ETHANOL is a subset of biomass that is manufactured from alcohols, ethers, esters, and other chemicals extracted from plant and tree residue. It can be made from corn, sugar, wheat, and barley.
HYDROGEN HYDROGEN fuel is a byproduct of chemically-mixing hydrogen and oxygen to produce electricity, water, and heat. It’s stored in a “cell” or battery. renewable
GEOTHERMAL GEOTHERMAL ENERGY is generated by heat in the earth’s core. It is found underground by drilling steam wells (like oil drilling).. nonrenewable renewable
