Energia solare: cos'è, come si converte in elettricità e calore, pro e ...
Partiamo con i vantaggi. Questi sono legati principalmente alla natura rinnovabile di questa energia, essendo il Sole una fonte inesauribile.
OWID 2020
A partire dagli anni '90 la produzione di energia solare è aumentata, grazie allo sviluppo di tecnologie sempre più efficienti e ai costi sempre più accessibili. Dalla mappa sottostante è possibile notare come i maggiori produttori di energia solare siano Cina e USA, seguiti da India, Spagna, Australia e SudAfrica. Nel mondo nel 2020 sono stati prodotti qualcosa come 800 TWh (terawatt-ora) da energia solare ( <anchor>OWID 2020</anchor>).

### How we process data at Our World in Data

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.

At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.

##### Notes on our processing step for this indicator

- We rely on Ember as the primary source of electricity data. While the Energy Institute (EI) provides primary energy (not just electricity) consumption data and it provides a longer time-series (dating back to 1965) than Ember (which only dates back to 1990), EI does not provide data for all countries or for all sources of electricity (for example, only Ember provides data on electricity from bioenergy). So, where data from Ember is available for a given country and year, we rely on it as the primary source. We then supplement this with data from EI where data from Ember is not available.
