2.4 Conservation and management of energy resources Flashcards
strategies for the efficient management of energy resources
6
- reducing consumption
- energy from waste cooking oil
- exploiting existing energy sources
- education of people for energy consumption
- transport policies
- fracking
- reducing consumption
- using insulation
- turning electrical devices off
- using energy-efficient devices and vehicles
- energy from waste cooking oil
- cooking oil can be recycled into biofuel
- anaerobic respiration of waste produces methane which is flammable that can be used for heating purposes
- exploiting existing energy sources
use other sources of energy available within the country
education
- Educating people from a very young age about the need to save energy
- Educating consumers about strategies to reduce consumption by changing their behavior can lead to dramatic results.
- Energy-efficiency ratings must be provided for new products to compare with the old ones.
transport policies
- restrictions on where vehicles may go,
- number of vehicles owned by individuals,
- taxation on fuels,
- providing grant to vehicles using cleaner technology (solar energy, electrical power cars)
fracking
- obtaining oil or gas from shale rock by splitting them open using water, sand and chemicals.
process of fracking
- A vertical hole (2-3 km deep) is drilled to reach the fuel-rich rocks (shale rocks).
- Water, sand and chemicals are pumped down into the shale rock layer.
- This causes the rock to fracture, releasing oil and natural gas, which are forced back to the surface and collected.
Purpose of the three components in fracking:
Water: easy to handle (in high pressure).
Chemicals: stop the blockage of pipes.
Sand: keeps the cracks in the rock open
ad and dis of fracking
Advantages
* Access to more oil and gas;
* Less pollution than burning coal
* The need to import is reduced;
* Provide many jobs locally.
disadvantage
* Chemicals are toxic and may affect local residents;
* Uses a lot of water; may cause water scarcity;
* Noise pollution;
* Natural areas damaged;
* May cause additional Earth tremors (shaking (man-made earthquakes))
