Energy Resources Flashcards
An example of a Non-renewable resource is ___________
Fossil fuels
__________ are gone when they are used up
Non-renewable resources
Non-renewable resource are made from _________
Remains of organisms
3 types of fossil fuels are:
1) coal
2) oil
3) natural gas
Coal
- Formed from plant remains
- must be mined from the ground
Oil
- liquid fossil fuels
- formed from small animals, Algae, and other organisms living in the sea
Natural gas
- mixture of methane and other gases
- formed from some of the same organisms as oil
Renewable resources
Constantly being supplied
Solar energy
- comes from sun
- direct or indirect source of many other renewable resources
Hydroelectric power
-Provided by flowing water
-
Wind power
- Can be use to turn turbines and generate electricity
- wind is a major source of power in where it is difficult I transport fuel
Biomass fuels
- made from living things
-
Geothermal energy
-Water is heated by magma or rock under earths surface
-
Hydrogen power
Pure hydrogen burns cleanly, creates no smog or acid rain, exists on earth in large supply
New clear power plants
- Another source of power comes from splitting the nucleus of an Adam
Energy conservation
2 ways to preserve or current energy resources:
1) increase the efficiency of our current use
2) reduce energy use
How to increase efficiency
1) installation to trap heat lost
2) better light bulb
3) better car tire and engines
4) reduce number of cars on road
Reduce energy use
1) bike riding/ walking can reduce the number of cars on a road
2) recycle
3) use fan instead of air condition
