Energy intro

What are renewable and non renewable resources(flow)
Renewable energy(non critical) is any natural occuring energy, theoretically inexautable source of energy as biomass, wind, tidal, wave HEP.

Non renewable-(stock)(critical) Any energy source that is not replaced that will run  out. A non-renewable resource (also known as a finite resource) is made up of deceased organic material.It consumed at a faster rate then its made it is unsustainable as it is running our meaning the needs of tomorrow are not accounted for.

Fossil fuels- a natural fuel such as coal, oil, and natural gas. Formed by geological past from remains of living organisms.

Primary energy- is sources in their raw form such as oil. They are used to produce secondary energy which are manufactured to produce (Electricity)

Crude oil is a fossil fuel found in liquid underground in ocean. its refined to produce petroleum
Natural Gas- a mixture of hydrocarbons occur with crude oil deposits
Coal- Black graphite, formed from fossilised plants and animal. 


Global patterns in energy- 

UK primary energy mix-  

Uk primary energy mix

As you can see it is not very diverse and sustainable as it relies heavily on non renewable energy resources.Only 2% is renewable. Over 70% of UK energy is supplied by oil and gas as the UK has reserves of both. In 1970 UK consumption of oil increased due to the discovery of the North Sea. The decreases in coal consumption or production in the UK is due to using clean energy and closure of mines as its easier to transports. Uks RE use has increased even though it 6% below EU average.HEP is at 3% as theirs not enough place to build these. Nuclear is dangerous Chernobyl disaster.

There has been an increase in oil and gas due to the discovery of the North sea this is beginning to run out.
Europe is the windiest countries.

Domestic production - is less than what we use.

Uk became a net importer in 2005.

The Global energy production is unevenly distributed.

Some countries have high energy reserve, some have fewer and produce less energy.

Wealthy countries tend to consume more energy and as years have gone on the amount of energy consumes has increased the use of oil, coal and gas have largerly increased while nuclear and HEP and renewable increased slightly this shows unsustainable development. There is also a trend that America, Europe and Asia consume more then they produce whilst the Middle East and Africa produce more then they consume. Also the more wealthier you are the more you spend. 87% of the world enegy comes form finite resources. Uneven distribution of oil  as half of the worlds oil reserves are in the Middle East this causes geopolitics. Oil trade is dominant in the Middle east as it supplies to Russia, America and Africa.

Consumption pattern- ›Fossil fuels make up 85% of World energy consumption

›Expected consumption increase across world

›Fastest increase in consumption in economically growing countries – China, Brazil & India

›Developed World consume 75% of the total supply of fossil fuels

Geopolitics that occurs due to energy distribution.

Energy security is important to governments

They all depend on energy.

At times there can be concerns to energy security which can lead to conflict.
