Energy and technology

2. ENERGY AND TECHNOLOGY -

Changes in energy and technological inovations are key aspects of the development of industrial activity.

TRADITIONAL ENERGY SOURCES - Most industry uses electrical power in its manufacturing processes.

- This electricity comes from the traditionl energy sources, but also from renewable sources..

- Traditional: 1. Oil: - It is most commonly used energy source because it provides gases, petrol, diesel oil, aeroplane fuel, lubricants, greases, waxes, asphalt and more.

- Limited oil reserves.

- Main reserves: in Venezuela, The Middle East, Canada, Russia, Libya, the United States and Nigeria.

2. Coal: - It was the most commonly used energy source during the Industrial Revolution.

- I is used to produce electricity in coal-fired power stations.

- Main reserves: in the United States,Russia and China.

Natural gas: - It is used in gas-fired power stations and for heating.

- Burning it produces less pollution than coal and oil.

- There are limited natural gas reserves, but more than oil.

- Main reserves ae located in Russia, Iran, Qatar and Turkmenistan Nuclear energy: - Nuclear power is used to move turbines which generate electricity.

- Nuclear accidents cause significant damage both people and the environment.

- Main producers are The United States and France.

- Japan and Germany are considering whether they should abandon this energy.

- China, Russia, India and South Korea are building new nuclear power plants.

2. ENERGY AND TECHNOLOGY -

TECHNOLOGY IN INDUSTRY Production processes use tools, methods and practical knowledge with different degrees of sophisication.

Rudimentary Technology - It inherited directly from artisanal manufacuring.

- Examples include tools used today to manufacture shoes (dies, brushes, moulds, hammers‌)

-

Traditional industrial technology - Machines and tools that originated during the first and second industrial revolution.

- Examples include industrial processes for manufacturing metal goods from minerals or looms in the textile industry.

-

Advanced technology - It is based on knowledge resulting from enormous amounts of practical research and innovation.

- Examples include research and development processes in sectors such as microelectronics, information technology, telecommunications, robotics and aeronautics.
