I know that renewable energy plants generate a clean electric power with no emissions, but manfacturing pv cells and wind turbines using nuclear of fuel based electric power raise a problem, also pv panels manufacturing process produce waste that are too hard to decompose and thus pollute the environement, also batteries and semiconductors uses a lot of nuclear electric power, the same with electrical vehicules, the manifacturing process generates wastes, so is there any artile that proves that renewable energy plants or electrical vehicule are good for the environement
When it comes to the energy used to produce and install renewable energy infrastructure, the Energy Return on Energy Invested (EROI) is often used. Older literature argued that the EROI of renewables is not high enough to support our economy. Good news for renewables: as with the cost learning curve, there is a EROI learning curve, i.e. technologies improve with more experience. As of today, renewables with a track record (PV and wind) have a relatively high EROI. See our paper on learning curves of power generation technologies in Energy & Env.

All forms of electricity generation have their impacts. Renewable energy installations are critical to keeping global warming under 2°C, and their environmental impacts should be investigated as rigorously as we evaluate non-renewables. Below are some examples of articles on this topic: https://www.nap.edu/read/12987/chapter/6#103 https://www.researchgate.net/publication/222010621_LCA_of_renewable_energy_for_electricity_generation_systems-A_review https://www.researchgate.net/publication/281550386_Environmental_Impacts_of_Renewable_Energy_Technologies

Localized pollution are easy to control than distributed. Pollution reduction is not digital process. It is an analog process (its journey). First milstone on this journey is renewable energy and electric vehicle
I can share an article that we did on the environmental external cost of Electric Power generation. It is bit old, but provides some interesting insights (e.g, that not necessary all renewable energy technologies have low environmental cost. The reference is:

thank you for your answers, i think it's a start of a journey as you have mentionned, the self sustainibility will be obtained when the manufacturing process of renewable energy generators come from green energy.
"... I know that renewable energy plants generate a clean electric power with no emissions...."
It's not true. Only natural forest or other natural plants set on fire after thundering will release as much CO2 as they consume. Otherwise, there is always additional CO2 emission, usually from dirty energy.

Few renewable energy plants are good for environment and some have some effects on environment like wind power plants hinder air flow, solar plants obstacle some area to be under shadow or return heat, holding more energy on Earth or vice versa, similar cases in others also and need to be considered, how much plants affecting natural process suitable to protect climate change anyway.
As you said, there are always trade-offs. I guess the article "Fossilizing Renewable Energies" from Sujatha Raman is a good read for you.
