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?

Natural Gas PetroleumPropane

Coal

Nuclear

Solar

Hydroelectric

Wind

BiomassEthanol

Geothermal

Hydrogen

Each energy source is either renewable or nonrenewable!

RENEWABLE NONRENEWABLE

ENERGYSOURCES OF

THE WORLD!

Renewable resources can be

replenished. Energy sources like

hydroelectric power, solar energy,

and wind power.

Renewable Energy Sources

RENEWABLE

ENERGYSOURCES OF

THE WORLD!

Nonrenewable resources take

millions of years to form and

cannot be regenerated in a

short period of time.

Nonrenewable Energy Sources

NONRENEWABLE

ENERGYSOURCES OF

THE WORLD!

PETROLEUMPETROLEUM is formed from animals and plants that lived millions of years ago when heat and pressure turned decayed matter into crude oil.

nonrenewable

PROPANEPROPANE is produced as a byproduct from natural gas processing and crude oil refining. It burns hotter and more evenly than other fuels.

nonrenewable

NATURAL GASNATURAL GAS consists primarily of methane but includes significant quantities of ethane, butane, propane, carbon dioxide, nitrogen, helium, and hydrogen sulfide.

nonrenewable

COALCOAL 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 ENERGYNUCLEAR 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 ENERGYSOLAR ENERGY is generated when photovoltaic (PV) cells convert heat from the sun directly into electricity.

renewable

HYDROELECTRICHYDROELECTRIC POWER is generated when flowing water turns turbines to run generators that convert energy into electricity.

renewable

WIND POWERWIND POWER is generated when wind turns turbines to run the generators that convert energy into electricity, which is then stored in batteries.

renewable

BIOMASSBIOMASS 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

ETHANOLETHANOL 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.

HYDROGENHYDROGEN 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

GEOTHERMALGEOTHERMAL ENERGY is generated by heat in the earth’s core. It is found underground by drilling steam wells (like oil drilling)..

S:

Use your home energy survey!

Easy ways to conserve energy

1. Buy local food to reduce food transportation over long distances

2. Set your refrigerator temperature to 37°F and your freezer close to 3°F

3. Turn down your water heater thermostat to 120°F

4. Keep your car tires properly inflated.

5. Clean your sidewalks with a broom instead of a water hose

Fossil Fuels – Nature’s Battery

Source: US Energy Information Administration

Today’s Energy 83 % = fossil fuels (oil, gas, coal) 17 % = nuclear and all other

sources

By 2035 81 % = fossil fuels (oil, gas, coal) 19 %= nuclear and all other

sources
