Like natural resources, energy sources can be divided into two broad groups depending on whether or not they are renewable. The supplies of non-renewable energy sources are limited, and they will run out the more we use them. Non-renewable energy sources include all fossil fuels: crude oil, natural gas, coal and shale gas. Nuclear power produces energy from radioactive uranium, which is a metallic element and therefore also a non-renewable energy source.
Renewable energy sources include solar power, water power and wind power. Various forms of biomass, such as wood, are also renewable energy sources. The advantage of these energy sources is that they will always renew themselves. Most renewable energy sources originally gain their energy from the Sun.

However, the largest source of Finnish energy consumption is industry. Industrial production is responsible for approximately half of the planet's total energy consumption. The refining of metals and the production of goods such as paper are examples of industrial processes that consume large amounts of energy.
