We either drill or import.
I may be talked into coastal, deep sea, or land wells as the most preferable.
But either we drill or someone else does and sells it to us.
I don't have stats on how much conservation can really save on imported oil. This is purely anecdotal and based on electric use at home.
We recently replaced the fridge, the A/C unit and the pool pump with one of those slow start models (expensive). Our monthly electric bill went from $150 a month to under $50.
