I think the California Air Resouces Board just duplicated it.
Ethanol is a proven disaster, causing food prices to increase while releasing copious quantities of greenhouse gases (which I care not about), guzzling scarce water resources, and costing more in energy to produce than it delivers in usable energy.
The Air Resources Board adopts a landmark regulation expected to slash gasoline consumption by 25% and encourage development of low-carbon fuel sources for cars and trucks.
Other biofuels are just as bad or worse, demanding water, land clearing, fertilizers, and burning lots of coal to produce electricity to make biofuels.
Hydrogen as a fuel is even worse, requiring even more electricity while delivering very little in useful product. Hydrogen at its best will be a totally impractical fuel for transporation.
My state, California, as usual leads the way in idiotic approaches to solving the problems of the future.
And as usual, most of the other states will follow California in a stampede of idiocy.
Idiots, like birds, flock together.
