Where radioactive material is found in the earth and is used
✅
Reliable
Renewable
❌
Limited to where it can be used and found
5
Q
Nuclear-
A
Nuclear power stations use radioactive materials such as uranium. The nucleus’ are split into two which creates energy ✅ No greenhouse gases Lots of electricity created ❌ Creates radioactive waste Which is expensive to get rid of
6
Q
Wind-
