Nuclear VS Renewable Energy

I think nuclear energy is useful fo everyone and it is also an energy that has many disadvantages as it can damage the environment.
On the one hand without nuclear energy we could not have all the technologies that we have now. But nueclear energy can damage the environment in the near future. Although we don't take any notice, but the damage will occur within a certain time and people don't want to cause any harm to their children. Due to the excessive harm of nuclear energy the best option would be to use renewable energy, but today it would be very expensive to use it
