what is goal 7?

point 7 is the objective of the 20/30 agenda which concerns the use and achievement of a rather high share of renewable energies.

Start

what types of renewable energies exist?

tipe of energy

There are various types of renewable energy:

solar

hydroelectric

wind power

geothermal

from biomass

and oceanic

advantages and disadvantages of renewable energies

An undeniable advantage is that renewable sources are inexhaustible, as their peculiar characteristic is to regenerate "automatically" as they exploit physical processes that occur naturally in the environment, which cannot be said of energy sources such as oil. or natural gas reserves that are destined to run out.

A second advantage is that they do not pollute or, in any case, have a minimal environmental impact and greater sustainability than non-renewable ones, not for nothing they are defined as clean energies. However, these are always clean energies with a minimal environmental impact compared to that caused by non-renewable energy sources.

advantages

The construction of plants that exploit RES can present disadvantages, for example an intensive and disproportionate use of dams could alter the balance of fish life, the same can be said of operations aimed at diverting the flow of rivers. The installations of large-scale wind or photovoltaic plants undoubtedly "subtract" portions of land that could be used as green areas, and there are also maintenance and disposal costs for these plants.

disvantages

what is Italy doing about renewable energy sources?

In the electricity sector, 37% of Italian consumption in 2020 was satisfied by renewable sources, with a production of about 116 TWh, thanks also to new plants installed for over 900 MW of power (of which about 750 of photovoltaic) and to increase in photovoltaic production.

Of this 37%, about 9% comes from wind energy and about 20% from hydroelectric energy, the inventories are made up of energy generated by photovoltaic and biomass plants and a small part by geothermal plants.

what can we do to further improve the use of renewable energies?

I I think we could increase and improve in the photovoltaic sector, especially in the southern areas of Italy, where there are large flat areas and a mild and sunny climate for most of the year.
