Fracking

Inferences...?
1. Why don't California-based operations invest in wind and/or solar power if they are looking for alternative energy supplies?
2. Qualified people should analyze data from these diverse places where fracking or geothermal drilling are being used to determine--as quickly as possible--if the correlations between underground water injections and earthquake swarms are indeed showing causation.
3. The earthquake-tsunami in Japan earlier this year has caused many people to re-examine the wisdom of using nuclear power plants; e.g. Germany will abandon them completely by the year 2020. Where does that waste material go?
4. As with climate change, there is a spectrum of scientists from highly reluctant to energetically emphatic about accepting theories that demonstrate that typical natural phenomena may be exacerbated by manmade activity. There may not be sufficient evidence in our lifetimes to prove it one way or the other--and then it may be too late. What happens if earthquake swarms in Guy, Arkansas get big enough to kill the town?
