Thanks, but how exactly is not a way of reducing prices? Right now the prices are high even though demand is actually comparatively low, there are also oil fields out there, specifically in Alaska that the oil companies are legally allowed to drill but they don't because drilling there would influence speculation in a way that prices would go down. Speculation is regulated, right now its regulated by the actions of oil companies rather then actions of the consumers and thats not good. If you regulate it, you can lower the price, if you continue to regulate it the price will not rise.
It's because speculation is used in commodity markets so that future increases in prices can be hedged against. As a result prices are frozen (for example, say a barrel of oil is worth $150 and they promise to pay $175 for an extended period of time - prices are forced up, though there is stability for the company doing the speculating). The importance of the stability is that it allows costly investment allowing for new production, be it increases in drilling or R&D in alternative energy.
However, the bad in removing speculation is even worse. Supported by theory and real life examples, the removal of speculation from a commodity market causes a tight market meaning that the firm will increase their spot-market purchases to attempt to create the stability that is created by speculation. This version of hedging against rising prices rises prices even more than speculation does.
Short story is, speculation is the most efficient manner in which the firm can hedge against rising prices in that it will keep the prices the lowest. For future reference, when I use the term regulation I'm referring to government, though I completely understood what you meant when you used it in the context of consumers and oil companies.
Energy prices will never again go down because the corporations have made a very cunning discovery: We need to pay their prices, and we can't do jack 'bout it. So they spend time generating excuses for high prices, so that when people complain they can turn around and say "No, see. There's a good reason for high prices! Look at our speculation. Eat our bull****. EAT IT."
The only solution is to protest all fuel products, for the next few years. If enough people did it...
So why exactly would energy corporations wish to keep prices so extravagantly high so as to create monetary incentives for alternatives to rise. The people who run these corporations aren't dumb people surrounded by dumb people - they realize that such a high price is worse for them in the long term even with massive short term profit. All you have to do is look politically at support for alternatives (support for nuclear energy, subsidies, government investment in R&D) and the massive increase in private R&D in alternative energy. Demagoguing the oil corporations is a political expedient, not an economic reality.
