Speaking here as citizen of a foreign country ...
The USA consumes way more oil and energy of all types than it produces. As such you must buy on the world market and pay the world price.
Your contention that demand for oil has declined or is flat may or may not be true for the American economy but in a world wide context it is false. The balance between supply and demand for oil is precarious and just a slight imbalance causes a big movement in price. China provided that slight imbalance coupled with some declines in production in a few major oil producers (Russia, Nigeria and Mexico).
Canada is a major producer of all sorts of energy but we do not sell it to ourselves at a subsidized rate. We charge the world price to ourselves (and to you) for a simple reason - we learned long ago that distorting a market with subsidies is costly and prevents the long term adjustment that price provides.
Oil companies who have access to oil reserves that they can pump do make a huge windfall profit. But they also took a huge risk at some point in the past to drill. Right now, the Beaufort Sea has large reserves of oil. It may be just profitable at current prices ~$125/barrel to extract BUT it is risky. The Beaufort Sea is in the Arctic, there is not an oil pipeline through the Mackenzie Valley and a large investment is required before any profit can be made. The Crown owns the resource but I would be most surprised if the government were to go back into the oil business (didnt we learn that once with PetroCan?). An oil company who makes the investment today in the Beaufort Sea may someday make an enormous profit when oil is worth ~$250 per barrel but that is the stakes that are being discussed.
I am not an American citizen and cannot vote or otherwise have a say in American policy. For us here in Canada, I am in favour of maintaining the sale of energy at the world price ie no subsidy, making additional investments in nuclear power generation and encouraging (not through tax breaks!) the private sector to make the investment required to extract natural resources like oil.
The only thing I can wish for about the American approach is that if you continue to burn coal, at least do it cleanly. Global warming, true or otherwise, is a benefit to Canadians (just ask anyone around Ottawa if a few degrees warmer wouldn't be better!) but polluting the atmosphere is not helpful to those like us who have the prevailing winds blow our way.
