But the discussion of whether something is renewable is also a complex topic that is only true to some extent. Renewable energy sources (Wind and Solar) are technically not renewable - the production of the equipment uses raw resources that we (today) cannot renew indefinitely.

However, for both Nuclear and Solar/Wind energy we do know, that the energy sources are sufficiently abundant to sustain us almost indefinitely without us upsetting other ecological balances.
