With all the concerns associated with non-renewable resources, why haven't we switched over to 100% renewable energy resources? *
1)They do not produce as much energy as non-renewable resources
2)They are much too costly, and the resources are hard to find
3)They have serious environmental concerns associated with them

Sample Response: "The one major change that occurred was the placement and organization of the electron. Rutherford’s model identified that the electrons were at a distance from the nucleus, Bohr’s model identified that the electrons occurred at levels that related to their available energy, and the modern atomic model shows that electrons are located in a predicted area but cannot be identified in a specific point".
