WHAT SECONDARY SECTOR ACTIVITIES ARE THERE?

The secondary sector uses raw materials to produce manufactured products. Some of the most important secondary sector activities in Spain are the food, motor and chemical industries. The technology industry has also become very important in recent years.

Types of products: Industries in the secondary sector can be classified by the types of products that they produce:

• Intermediate products: some industries produce intermediate products. These are products that are used by other industries. (The steel industry converts iron into steel, that is used to make cars and buses).
• Consumer products: some industries make products that are sold directly to consumers. (The food industry transforms products from farming and fishing into consumer products).

Energy sources: factories need energy to transform raw materials into products.WH

• Some energy comes from renewable sources, such as sunlight, water or wind. These sources of energy are unlimited.
• Some energy comes from non-renewable sources, such as coal, oil, natural gas and nuclear energy. These sources of energy are limited.
