The seed I found had fallen of a tree, and was missing its cap, or cupule. The oak specie of holm oak trees are known to grow in southern Europe, including France. The holm oak's scientific name is the Quercus ilex. It's a large evergreen tree, and is known to survive best in warmer climates. In the frost or colder temperatures, the tree would not survive, which is why it's more present in the South.
The wood of this tree is very hard and tough, meaning it can be used for building things such as wagons, tools, and more. This wood has been used since the ancient times. Iberian pigs are also usually fed with these acorns for nutrients.
Bordeaux is planning to become the first ville solaire (solar city) in France! The city is planning to install 60,000 square meters of photovoltaic panels onto the roofs of public buildings by 2026! Photovoltaics is the conversion of light into electricity, and a photovoltaic cell (PV) is also most commonly known as a solar cell! This plan was set forth by Bordeaux's environmentalist mayor Pierre Hurmic. His plan is to meet this goal before the end of his term in 2026. He wants to reach 41% of energy autonomy! This is important as this would mean Bordeaux would be able to produce most or all of their energy without relying on any external sources.
By having local renewable energy, you can also have a backup in case things go wrong with your other sources of energy and make them inaccessible. Renewable energy also is wonderful for the environment and Earth.
