Do you think that a switch to an alternative fuel source would positively or negatively impact America's economy?

If it's produced domestically, then positively.

1. Do you feel that the gain environmentally and in efficiency would offset the potential of thousands to maybe tens of thousands jobs lost?

There's always a potential loss when you switch from any system to another. Depending on the fuel source it could actually create jobs. Say ...growing huge tracts of algae. But yea, if we don't do something soon then transportation will be the last of our worries.

2. Do you feel that Oil companies are actively trying to keep non-Petro fuel sources inefficient and underdeveloped to protect their profits at the expense of America's health and well-being?

Of course they are.

3. Do you feel that less reliance on foreign Oil would further alienate and ruin the economy of those countries that we purchase it from, were we to switch from Oil as a fuel source?

Whether or not it will ruin their economies is not our concern. We have to worry about ourselves first, them second. However, alternative fuel sources are a step in the way of becoming carbon neutral, which will benefit them as well as us.
