Today the concept of renewable energy sources is spreading more and more, thanks to the progress made in the energy sector and to the growing concern about climate change and global warming that lead to look for the alternative energy sources of the future. The most recent international deal on climate change is the Glasgow Climate Pact, reached during the COP26 of October-Novembre 2021.<\/p>

Since the era of the first industrial revolution in the mid-700s and up to a few years ago, the energy resources of our planet have been quickly consumed and this has led to the consequences we know. For this reason, the renewable sources, which can be naturally regenerated, are the right answer to an increasingly dramatic environmental transformation.<\/p>

Even if the energy produced by renewable sources is a clean energy, some natural resources can end if no action is taken in time. The use of wood, for example, brings to the problem of wild deforestation. Wooden houses with solar energy, the main renewable source that turns into electricity and heat for humans, are prefabricated houses that use photovoltaic panels and solar thermal energy. Solar energy is one of the most important alternative energy sources of the future.<\/p>

Other examples of renewable energy sources are the wind energy produced through the wind, as well as the marine energy<\/a> generated through the sea and the oceans, the geothermal energy that uses the heat of the earth, the energy of the hydrothermal water and the energy produced by the vegetable and animal waste (biomass).<\/p>

The currently used non-renewable sources, such as fossil and nuclear energy, have proven to be the cause of the critical climatic conditions we are currently experiencing. Furthermore, these energy sources are being exhausted quickly, so if we want to improve the conditions of the planet, as well as our own lives, we need to change our lifestyle. A solution could be to replace fossil resources with renewable energy sources, thus contributing to save our planet. It’s common knowledge that the future of non conventional energy resources is directly linked to our own.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Renewable energies<\/a> are inexhaustible natural energy resources, such as solar, wind and hydroelectric energy. Other renewable resources depend on human cultivation and exploitation, such as biomass. In this case, we refer to “sustainability<\/b>“.<\/p>

However, when is a renewable energy source sustainable? In the case of exhaustible energy resources, such as biomass, a rational use of energy flow over time is necessary, as in the case of forest exploitation. In this case, the man must make sure that the growth of the new trees planted is equal to or greater than the number of trees felled. This is an example of sustainability.<\/p>

Let’s take a look at the most developed renewable energy sources.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The energy that comes from the sun<\/a> is the primary energy source on Earth. The sun is, in fact, a green, inexhaustible energy resource, and the amount of energy it produces can, by itself, meet the energy needs of the entire humanity. Its limits are large-scale production, collection and processing difficulties and intermittent production. However, solar energy remains an excellent form of energy for business and domestic use, especially when it is supported by any financing. In fact, it involves considerable savings and does not require excessive maintenance.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The energy generated by the wind is also a form of renewable and inexhaustible energy. The power of the wind, in fact, generates mechanical energy. The energy produced by windmills, for example, is spread in the windiest places and can in turn be transformed into electricity.
The energy produced by wind power is a stable alternative over the long term, but it records important variations in daily production, making it necessary to have storage facilities and other alternative energy sources. As for the profits, instead, the installation of these plants requires very little maintenance and at the same time guarantees a significant saving on the energy bill. Wind energy is growing in Italy, but in some countries it has already achieved excellent results. This is the case of Netherlands and of its trains that travel thanks to wind energy since 2017. In that country, wind energy is already the energy source of the future.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Hydroelectric energy is produced by the force of water masses in motion, such as water flowing or falling from a gradient (just think of the rivers and waterfalls), which first generate kinetic energy, later transformed into mechanical energy from turbines and finally in electricity from electric generators. The amount of energy produced may depend on both the flow of water and the position of the plant or of the existing gradient. The green energy produced is one of the clean energies that have a reduced impact on the environment, so the building of large hydroelectric basins would have a significant environmental and socio-economic impact.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The geothermal energy is extracted from the subsoil, and it exploits the natural heat of the Earth.<\/p>\n

It is an excellent investment because it is available throughout the whole day and produces green energy thanks to long-term guaranteed installations. Nevertheless, today it is used to satisfy a very small percentage of the world demand.<\/p>\n

Geothermal energy is different from thermal energy, which is obtained from any body that has a temperature above zero. Not all thermal energy is likely to become mechanical energy, but any energy can become thermal energy in the long run.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Inexhaustible and clean renewable energies reduce the environmental impact and are spreading rapidly, so as to cover half of the world’s energy by 2050. Beyond the initial investment, the benefits of these energy sources are obvious:<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
