Energy Resources
Unit 3 Energy
| Term | Definition |
|---|---|
| Energy Resources | A natural resource that people can turn into other forms of energy to do work |
| Renewable Resources | A natural resource that can be used and replaced over a relatively short period of time |
| Biomass | Renewable Comes from organic matter –trees, crops, wood, waste Use it by burning it to create steam to turn turbines and spin generators or Bacterial decay (compost) or fermentation (makes ethyl alcohol) Electricity Con-Burning creates pollution |
| Hydropower | Renewable Energy comes from moving water Water flows through dams and turns turbines to spin generators. Used for electricity Con- Can disrupt natural habitats |
| Geothermal | Renewable Heat comes from inside the Earth Drill holes in the crust and use the steam to turn turbines and spin generators. Used for heating and electricity Con- Can’t be used everywhere |
| Wind | Renewable Kinetic energy (motion) of air because of the uneven heating of the Earth. Wind machine turns and spins a generator. Used for electricity Con- Can’t be used everywhere |
| Solar | Renewable Energy from the sun Solar panels and collectors absorb solar energy and convert it to electrical energy. Used for electricity, heat and light Cons - difficult to collect and store expensive |
| Nonrenewable Resources | Natural resources that cannot be replaced or that can be replaced only over thousands or millions of years. |
| Fossil Fuels | Formed from buried remains of plants and animals that lived millions of years ago Include coal, petroleum, propane and natural gas Non-renewable |
| Petroleum | Non-renewable Made from the dead remains of plants and animals. (fossil fuel) Found in sedimentary rocks Burned to get energy Used for transportation, heating, making products Con- releases greenhouse gases (pollution) |
| Natural Gas | Non-renewable Made from the dead remains of plants and animals. (fossil fuel) ; Found in sedimentary rocks Burned to get energy Used for heating, electricity, and some transportation Con– Releases greenhouse gases |
| Propane | Non-renewable Fossil fuel; Found in Natural gas Burned to get energy Used for electricity, heating, transportation Con- Creates some pollution but cleaner than other fossil fuels |
| Coal | Non-renewable Fossil fuel from dead plants; Black rock Burned to get energy Used for electricity, heating, manufacturing steel Con– Releases greenhouse gases |
| Uranium | Nonrenewable Metal found in rocks Fission Splits atoms, releases heat which creates steam to turn turbines and spin generators. Used for Electricity Con- Creates radioactive waste |
| Example of Nuclear energy | Uranium |
| Energy from fossil fuels comes from | The sun |
