RE: New alternatives to generate electricity / Wind turbine without blades
You are viewing a single comment's thread:
Once I was in a meeting of the environmental group I belong to and they were talking about this topic and they made an analysis about which was the healthiest and most productive and they came to the conclusion that it was hydroelectric because producing solar energy still costs a lot and wind turbines represent a costly investment as well, as to massify it as a means to bring electricity to the cities. Fossil fuel is undoubtedly the most polluting and nuclear energy the most dangerous.

Hello @joseph1956.
That has been the task of science-technology of the last decades, that is, the constant search for any other source of electric current generation as an alternative to that generated with the implementation of fossil fuels.
The great challenge has always been the cost of these new alternatives, but nevertheless, with time they are becoming more accessible to most citizens.
Thanks friend for your great contribution. Regards.
