Crude oil

1. Crude oil

2. Energy density • Oil has an energy density of 34 megajoules per litre. This high compared to the energy density of wind or tidal. • Renewable/non renewable • It is non renewable since we are using it up faster than it can grow back • It takes millions of years for oil to form, but it has only lasted just over a century to use up

3. Intermittency • Oil is non intermittent since it can be used continuously • Reliability • Oil is very reliable, we can harness its energy very efficiently and safely. • Ease of Storage • Oil can be stored very easily in pipelines, and barrels and large ships which carry around the world

4. Available resource • The supplies of oil are running out quickly, they are expected to run out in the next 40 years. And it is getting more and more expensive. • Geographical and locational factors • There are lots of oil deposits in the Middle east, but they are in politically unstable countries. They can also be found deep beneath the ocean. The supplies will only be extracted if it is economically viable.

5. OIL RESERVES

6. Level of technological development • All the research and technology for oil extraction is already in place. • Environmental impact • Co2 is released by burning oil, contributing to climate change. • Political and trade issues • The worlds governments rely on oil because there is a huge amount of infra structure already in place for it. And countries with large amounts of oil can hold more power over countries without it.

7. Economic issues • There are economic issues associated with oil, one being that it is getting more and more expensive. Applicability to particular uses • Oil is refined and used as fuel for cars
