Clean energy, also known as green energy, plays a fundamental role in the quest for a more sustainable future. This category of energy is distinguished by its ability to produce few or no pollutants, thereby preserving our environment. Powered by sources such as the sun, wind, or biomass, it proves to be a valuable alternative to traditional methods which are often harmful. As the world strives to meet environmental challenges, clean energy emerges as an essential driver for the energy transition and sustainable development.
Clean energy refers to sources of energy that are environmentally friendly, generating few or no pollutants. This form of energy is often confused with renewable energy. However, although most renewable energies are clean, some, like nuclear, which still utilize fossil fuels, can also be considered clean energy due to their low pollutant emissions.
The reason clean energy is vital is that it aims to reduce greenhouse gas emissions, which are essential for combating climate change. Clean energy sources include, among others, solar energy, wind energy, geothermal energy, hydroelectric energy, and biomass. Each of these sources harnesses its energy from inexhaustible resources, such as the sun, wind, geothermal heat, water, and organic materials respectively.
Regarding solar energy, it involves capturing the sun’s energy through photovoltaic panels to generate electricity. This form of energy is increasingly used, particularly by companies seeking to reduce their dependence on traditional energy sources. (To learn more, visit this link).
Wind energy, on the other hand, harnesses the power of the wind to turn turbines that produce electricity. It is an essential form of clean energy that is rapidly emerging worldwide, although some countries are progressing faster than others. China, for instance, has achieved its energy goals much more quickly than anticipated (see here).
Geothermal energy derives its power from the Earth’s natural heat. This energy is captured in the form of steam or hot water, which is then used to generate electricity or heat homes and buildings. It is a particularly useful resource in volcanic regions.
Hydroelectricity uses the force of water (commonly rivers or dams) to generate energy. It is one of the oldest forms of clean energy and is widely used in countries with abundant water resources.
Biomass utilizes organic materials (such as agricultural residues, animal waste, or industrial waste) to produce heat, electricity, or fuels. This form of energy helps reduce waste while providing a source of clean energy.
Finally, although emphasis is often placed on renewable energies, the importance of storage and distribution infrastructure for their effective exploitation should not be overlooked. The transition to sustainable energy consumption also requires strong political support as well as ongoing innovations despite global political fluctuations, as shown by a recent analysis of U.S. policies (check this link).
