Conservation is always cheaper than generation. Seems to me we're way overdue substantially higher energy prices, particularly vehicle fuel. How high is necessary to effect a consumer change that the gov't isn't willing to mandate? I've seen various predictions. CAFE is a problem that needs fixing. Market dictate is fine by me. Looking where fuel prices are already at that level shows very different vehicles available. Bought a new van for my wife's business two years ago. Was not able to get diesel in E150. Something very wrong with that picture. Nor is there a slightly smaller van built similar available. E150 is 18" (wasted in our case) longer than the discontinued Dodge. Minis aren't applicable, tried that. Myself, built a house that never gets hot or cold, appropriate for about any climate. Passive Annual Heat Storage (PAHS). Next is going off-grid. Large machinery dictates substantial generation, 25 kW in my case. Woodgas is my best bet. Which can also power a vehicle if one makes the effort. I don't drive much. There have been a couple of very interesting hydrogen developments lately. One greatly reducing the electricity needed for generation, using biology. The other possibly doubling the efficiency of fuel cells with better fuel storage. I'm not holding my breath, waiting. Better to get moving.
