  • 3rd side (hint)
A device that converts mechanical energy into electric energy.
What is an Electric Generator? (280)
Moves an electrically conductive material such as copper through an electric field converting the energy into electricity.
The remains of organisms that lived millions of years ago.
What are Fossil Fuels? (281)
Ex. Coal, Oil & Natural Gas
Those natural resources that are continually produced or recycled.
What are Renewable Resources?
Ex. Wind and sunlight are considered inexhaustible.
The energy that exists within the nucleus of an atom.
What is Nuclear Energy? (283)
Ex. This new energy source was developed in the 1950's & 1960's & promoted as "energy too cheap to meter"
When subatomic bonds are broken apart releasing huge amounts of energy.
What is Nuclear Fission? (283)
Ex. Energy released through splitting atoms as in a nuclear reactor or atomic bomb.
Resources that can not be reproduced by man such as Fossil Fuels.
What are Nonrenewable Resources? (282)
Ex. Fossil fuels include Coal, Oil, & Natural Gas
The process of combining lightweight atomic nuclei to form a heavier nucleus, releasing large amounts of energy in the process.
What is Nuclear Fusion? (286)
The sun creates energy (heat & light) by combining two hydrogen atoms to make 1 helium atom continually in chain reaction.
A positively charged particle in the nucleus of an atom.
What is a Proton? (283)
This nuclear particle has most of the weight of nucleus and a positive + charge.
A neutral/uncharged particle in the nucleus of an atom.
What is a Neutron? (283)
When the neutrons are released in the splitting of atom they cause other atoms to split by fission making a chain reaction.
The energy from the sun.
What is Solar Energy? (288)
Clean, safe, & renewable energy.
Sunlight is used to heat buildings directly without pumps or fans.
What is Passive Solar Energy?
Construction materials make & store this energy for heating in these buildings/houses.
Making use of solar collectors to capture the sun's energy & transform it by heat exchangers into heated water.
What is Solar Water Heating?
Uses a closed loop system which transfers sun's energy to the water we use daily.
Devices that convert the sun's energy directly into electricity.
What are Solar Cells? (290)
Semiconductors absorb sunlight releasing electrons which flow through a circuit completed when another semiconductor in the ______ _____ absorbs & passes them on to the 1st semiconductor.
Devices such as panes used atop buildings to collect solar heat and deliver it to a heat exchanger which heats up water for use.
What are Solar Collectors (290)
Devices allow for liquid to run through them which is heated by sun.
Electricity produced by converting the energy of moving water.
What is Hydroelectricity?
Dams use power plants which house turbines at their base which turn with the force of falling water when the gates are opened creating electricity.
Energy that is drawn from heat within the Earth and used to drive electric generators.
What is Geothermal Energy? (292)
Yellowstone National Park has untapped sources of this type energy. New Zealand and Iceland both used it until usage depleted its source.
