Ethanol and biodiesel are replacements for fossil gasoline. Cellulosic ethanol will help because cellulose is the most abundant organic molecule on earth. There is also a mixed alcohols system developed at Texas A&M by Holtzapple that looks promising. The fundamental problem with all of these schemes is that the land area required is enormous. Corn produces about 3.4 tonnes per acre whereas energy cane produces 30 tonnes per acre, so the crops will need to change. Aquatic plants are even more productive. Water hyacinth is an ecological disaster, but the productivity is 70 tonnes per acre. Algae is still more productive. The entire US demand for transport fuel could be met from this source for less than the cost of invading Iraq.

There are these "scientist" that claim to have produced "free" energy. basically made a perpetual motion machine. Even though this contradicts fundamental laws of physics and thermodynamics it brings out some skepticism in my end. But i am still hoping that they might actually have something. What they have done is placed an advertisement in the Economist and asked all of the scientist to sing up to become one of the people who will run tests on the device. If they are right, then we will have no use of any power source. This will change the world.

I think cellutrol or cellular ethanol is very intriguing.
University of Florida is working with someone on a plant and the Canadian Government is partnering with BP on it. Similar to ethanol except:
-has approximately the same potential energy as regular gasoline (ethenon has about 66% potential energy of gas)
-Made from almost any cellunose biomass (eg: corn stalks, straw, grain husks)
It could create an energy economy that has a byproduct of food. That could be fascinating.

suitable now, it particularly is the two hydrogen or electrical energy. EDIT: seem, it particularly is not biodiesel; that has in simple terms made the nutrition fees circulate up lots that it has exacerbated the starvation problems of the poorest of the undesirable. it particularly is not methanol the two; you're nonetheless transforming into something and burning it. it particularly is a minimum of carbon impartial, even though it would not incredibly tackle the "making gas of nutrition that some starving guy or woman ought to consume" situation. Arguably, our contemporary infrastructure demands the two gas cells (changing at as quickly as from hydrogen to water and electrical energy), burning hydrogen at as quickly as, or applying some sort of battery ability (possibly applying nano batteries) and electric engines. till we've fusion (if the Italians have been given it suitable we've already have been given it), wherein case each thing must be in line with electrical energy.

yeah, but there are many non-conventional resources, Like Bio-Gas, Tidal energy ad Wind energy that can be trapped by the use of Windmills.
Apart from this, Hydroelectricity is of course, the most widely used, although building a dam and barriers could take a ot of money and time.
