  • Biofuels and aviation

    Using sustainable biofuels represents one of the most effective ways to reduce CO2 emissions in aviation. If the aviation sector switches to sustainable biofuels on a large scale, CO2 emissions can decrease by as much as 80%. Biofuel is therefore much more sustainable than fossil fuel, which is the current standard within the aviation sector. […]

  • Geothermal energy

    A source of enormous energy is located deep inside the Earth. The Earth stores this energy as heat, therefore, we call it geothermal energy. Sometimes it is also referred to as “environmental energy”. Both the Earth’s top layer – the soil – and the layers deep inside the Earth contain this environmental energy. Environmental energy […]

  • Wind power

    Wind power is an excellent source of sustainable power. Wind energy never runs out. Moreover, it’s always a clean energy source, unlike the conventional fossil fuels, like coal or oil. The demand for fossil fuels worldwide is immense, the majority of the developed countries depend on oil and gas supplies. This dependency on fossil fuels […]

  • Solar power

    The Sun is a star that is approximately 150 million kilometers away from the Earth. The Sun is an inexhaustible source of energy, therefore, solar energy is sustainable energy. Our planet receives the energy of the Sun through radiation in the form of light and heat. This energy, together with the secondary forms of energy, […]

  • Biofuel: part 2

    Second and third generation of biofuels as sustainable energy sources 2nd generation of biofuels When people talk about the second generation of biofuels they usually refer to biofuels produced from food-unrelated materials. Plants grown specifically for this purpose make up the basis for this type of fuel. Inedible parts of certain food crops can also […]

  • Biofuel: part 1

    Biofuel as a sustainable energy source If you burn a piece of wood in your fireplace – a certain amount of CO2 comes out of the chimney. However, the tree that you are burning was growing in a forest and was taking CO2 out of the air not so long ago. The CO2 from the […]

  • Sustainable energy and alternative energy sources

    Currently fossil fuels satisfy the majority of mankind’s energy needs. The current fossil energy sources are, however, running out. Moreover, the way people use these fossil fuels to produce energy has a bad influence on the environment. The fossil fuels acting as the main sources of energy for our society are rapidly disappearing. The shortage […]
