The energy and ecological transition has led to the implementation of new plants for the exploitation of renewable energy sources . Wind, solar and storage batteries are at the forefront of strategies aimed at reducing Co2 emissions, decarbonising the planet and achieving net-zero.
Naturally, every new technology can be improved and its development can be directed towards greater sustainability. In this sense it is good to remember that plants that exploit renewable energy imply a massive use of metals which clashes with the objective of sustainability intrinsic to the renewable sources themselves.
Improving the use of metals in renewables
The development of new cutting-edge technologies identifies and supports a better use of metals in the exploitation of renewables for the production of clean electricity. The new trend is aimed at reducing the use of metals, the extraction of which leads to an increase in CO2 emissions, and then also recycling them.
So on the one hand there is a massive reduction in the use of aluminium, copper, silicon steel, nickel and cobalt, and on the other their recycling and reuse is being developed . Objective of greater efficiency and sustainability. Each metal will be progressively reduced in percentage until significant reductions are achieved.

The recycling and reuse of metals would turn towards the creation of new energy lines , thus contrasting the problems relating to the age-old disposal of waste deriving from renewable plants. The resulting circular economy would lead to a sort of continuous cycle of metals as an almost inexhaustible raw material.
Furthermore, the problem of their disposal and the significant reduction in their extraction, which causes considerable pollution , would be definitively eliminated . Respecting the perspective and primary objective of being able to produce clean energy in total protection of the environment and the health of our planet.

The green process has therefore begun which leads the new technologies for exploiting renewable energy to be even more sustainable, moving away from the massive use of metals. Green light for their recycling and reuse. This will bring benefits to the environment within the broader energy and ecological transition. A new generation of metals at the service of the next generation of renewable energy.
