|
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?
(282) |
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?
(288) |
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?
(290) |
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?
(292) |
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.
