Renewable energies, such as wind, solar, geothermal, hydroelectric, tidal and biomass, are clean and sustainable energy sources, which are potentially capable of solving various environmental and social issues as opposed to traditional fossil fuels such as oil, coal and natural gas.
Their main impact, which everyone is aware of, is related to the reduction of greenhouse gas emissions, which are responsible for global warming and climate change.
Equally important is that they are not subject to depletion: unlike non-renewable fossil fuels, whose availability is limited.
Another advantage is the production cost, which over the next few years is likely to decrease as green technologies become more widespread, compared to the cost of fossil fuels that is expected to increase gradually as they become depleted.
Last but not least, renewable energies, by their very nature, can contribute to reducing energy dependence on countries with fossil fuel reserves, with the geo-political implications this implies.
Lastly, another positive aspect of renewable energies is the potential economic impact linked to the development of local economies and the creation of new jobs in the supply chain of the technologies required for their use.
