The Spanish government has authorised the construction of almost 300 renewable power projects with a total capacity of more than 28 gigawatts, which will help the country meet its ambitious green energy goals, it said on Monday.

The projects, which will represent a combined investment worth over 17 billion euros ($18.4 billion), comprise mainly photovoltaic power plants, as well as 43 wind farms and one hydropower plant, the Energy Ministry said in a statement.Leveraging on its sunny plains, windy hillsides and fast-flowing rivers, Spain intends to raise the share of renewable-generated electricity to 81% of the total by 2030, up from about 50% now.
