Compared to fossil fuels, the use of biomass does not emit additional carbon dioxide into the atmosphere Bioenergy is obtained from organic matter by burning solid, liquid, or gaseous fuels. Most bioenergy is obtained through the use of various wood fuels (wood chips, pellets, firewood, etc.), less herbaceous biomass (hay, straw, reeds), biogas, biodiesel, or bioethanol. The main advantages of...

Estonian rivers have a relatively small hydropower potential and much of it is already in use In a hydroelectric power plant, the kinetic energy of the river’s falling or flowing water is converted into electricity. Hydropower is considered a type of so-called green energy because it avoids the consumption of fossil fuels and running water itself is a renewable energy source. However, there are...

As of the end of 2019, wind turbines accounted for slightly more than half of the production capacity of renewable electricity Wind is a renewable natural resource and a wind energy ecosystem service that humanity has been exploiting for thousands of years. The widespread use of wind energy can partly reduce the need to burn fossil fuels and consequently reduce CO 2 emissions. As wind energy is an...

Oil shale, or kukersite, is the most important mineral resource of Estonia, which has been the main source of electricity since 1924, but also a source of environmental problems The oil shale industry has significantly affected the socio-economic and natural environment of the Ida-Viru County for almost a century [1]. Due to oil shale mining and processing and activities related to oil shale...

What is renewable energy? By 2050, Europe should become a climate-neutral continent. In order to achieve that, the Member States of the European Union should also stop producing and consuming fossil fuels in the energy sector and invest more in renewable energy. Renewable energy is a resource (e.g. solar or wind, but also geothermal or wave energy) that is used continuously or that is recovered...

Estonia has an obligation to rehabilitate at least 2,000 ha of cut-over peatlands in the period of 2014–2020 Cut-over peatlands are former peat mining areas and mire areas used for agricultural purposes where economic activity has ceased [1]. Cut-over peatlands can be classified according to their formation and characteristics [2]; two of the most common indicators are the thickness of the peat...
