We often see homes that meet modern grounding standards still lose thousands of dollars of electrical equipment and appliances to surges from indirect lightning strikes and power company line surges.
Home built before 2008 commonly have a single ground rod, new building codes require at least 2 ground rods to offer extra redundancy & protection to this home system but this still only limits the voltage and provide a way to send it safely into the earth.
The electrical industry agrees that the best protected home is one with a good grounding system, and good surge protection working together.
