A common feature of renewable energy sources is that their sustainable use does not deplete their stocks in the long term. The goal of increasing the use of renewable energy sources is closely related to sustainable development and actions that do not limit the options of future generations.
Growth in the use of renewable energy sources is connected with climate agreements and curbing climate warming. Although the key motivation for increasing the use of renewable energy is reducing greenhouse gas emissions, use of renewable energy sources also promotes use of bioenergy and other domestic energy, steers society to invest in research and product development, and improves and maintains security of supply in the energy sector.
The renewable energy sources used in Finland are hydro and wind power, solar energy, aerothermal energy and ground heat captured by heat pumps, biogas, biodegradable parts of recovered and waste fuels, wood-based fuels, and other vegetable and animal-based fuels.
