Energiaallikateks refers to energy sources. These are natural resources or processes from which usable energy can be extracted. Broadly, energy sources are categorized into renewable and non-renewable types.

Non-renewable energy sources are finite and are consumed at a much faster rate than they can be replenished. The primary examples include fossil fuels such as coal, oil, and natural gas. Nuclear energy, derived from the fission of radioactive materials like uranium, is also often considered non-renewable due to the limited supply of these materials.

Renewable energy sources, on the other hand, are naturally replenished on a human timescale. Solar energy, harnessing sunlight, is a prominent example. Wind energy, utilizing the kinetic energy of moving air, is another significant source. Hydropower, generated from the movement of water, has been used for centuries. Geothermal energy taps into the Earth's internal heat. Biomass, derived from organic matter, can also serve as a renewable energy source if managed sustainably. The transition towards renewable energy sources is driven by concerns about climate change, resource depletion, and energy security. Each energy source has its own set of advantages, disadvantages, and environmental impacts.
