The world is discussing renewable energy sources as the 2021 United Nations Climate Change Conference (COP26) takes place in Glasgow, Scotland.
But is it possible to obtain 100% sustainable clean energy? For the theoretical physicist Jacques Trainer, this is not yet possible. According to an interview for Euronews, there is no such thing as 100% renewable energy.
The theoretical physicist explains that there is no zero carbon emission in manufacturing devices to produce renewable energy. In other words, the production of equipment, such as photovoltaic panels, is still not sustainable.
For this to happen, the production of such equipment must use renewable energy sources, with zero carbon emissions into the atmosphere.
“There are no zero-emission energy sources because you have to manufacture the devices, the installation, you have to manufacture them. And for them to have zero-emission, there would have to be combinations of energy with zero-emission.”
In addition to talking about sustainable energy, Jacques Trainer said that the concept of “green energy” does not exist. For the specialist, “energy has no color” and should only be associated with the emission or not of carbon into the atmosphere.
“Energy has no color: Green, grey, red, or blue, I do not know. What I do know is which energy sources emit greenhouse gases or not.”
