as it stands now, technologies other than oil/natural gases will not be fully developed/used/cost effective until the big oil companies suck every last bit of oil out of this planet at any cost. just look at the potential drilling in alaska and the alberta oilsands. absolutely disgusting and globally irresponsible activities. i've had a chance to see the oilsands with my own eyes and it's absolutely appalling... the amount of destruction to the evironment is breath-taking and irreversible.
i have no trust in the free market. the free market is only out for itself at any cost. the mantra of capitalism is "maximize shareholder wealth"... at any cost. as long as a company makes a buck at the end of the day they don't care how many people die, how many lives they've ruined. it's all about the balance sheet.
