Amber, I agree with your enthusiasm about solar power, and think everything possible must be done to encourage it.  However, attacking coal as a source of electricity generation won't be very useful locally for Lane Community College, since Eugene's power is mostly hydroelectric, and only a trace amount comes from coal (see http://www.eweb.org/resources ).  I think your local OSPIRG chapter might be more effective with an "act locally" campaign.

Ex Output:

Yes
