The advantages
Compared to traditional sources, the renewable ones show several important advantages from the environmental, sanitary and economic point of view.
Advantages for the environment
The energy production from fossil fuel or nuclear energy implies heavy negative emissions from the environmental point of view, among them the increase in CO2 in the atmosphere, the main cause for the global warming, and the production of harmful substances such as, for example, fine dust, mercury and sulphur dioxide (SO2), responsible for the acid rains phenomenon. Other external effects comprise changes in the chemical composition of the soil, layers pollution, lakes and rivers becoming acid.
Instead, renewable energies are characterised by:
- full sustainability
- very small environmental impact
- inexhaustibility of the sources.
Advantages for health
The same pollutant substances produced by fossil fuel or by nuclear energy and affecting the environment are also very harmful for human health, favouring or causing pulmonary and cardiovascular illnesses, neurological disorder, cancer, miscarriages, malformations.
Economic advantages
By diversifying energetic sources and guaranteeing a constant energy supply, the strategy of the renewables turns out to be winning from the economic point of view as well:
- it reduces the dependency from imported resources
- it contributes to preserve the natural territory heritageo
- it reduces energy costs to everybody’s advantage
- it favours economic development and employment
- stabilizes energy prices
