benefits can make you have more energy by promoting the production of red blood cells. there aren't any bad side effects because iron is something your body needs (without it you become anemic and tired:o()

Hemp is a energy crop. This means that it isn't a fuel itself, but is good for making energy products. \n\nThe better of Industrial Hemp seed lines produce as much seed as corn by dry weight. Industrial Hemp can produce more cellulose than corn can hope to. It is in the range of crops grown for cellulose. All of those crops can reach above 10 tons an acre per 4 month growing season under the correct conditions. Cellulose can be used for ethanol, biodiesel, coal replacement, etc.  \n\nIn that respect it isn't better than other crops. It is much the same as most good types of energy crops. They all have their ups and downs. However among energy crops, hemp is the only one that has 10,000 plus current other uses.\n\nAs to what is the best solution. \n\nButanol is the most ideal. It is almost as powerful as today's petro fuels, and it can be used in direct replacement of all current gasoline engines. The downside is that it lacks a biofuel industry to make it. There is only one company that is building a pilot production facility. The current butanol industry reforms it from petroleum. In a dozen year I hope this will change greatly as there is much interest in this.      \nYou will have to check out http://www.butanol.com/ for info. \n\nEthanol is plausible. Unfortunately the oil industry has done its best to turn public opinion against ethanol and is succeeding. Because of that I doubt the industry will ever reach the levels needed to replace gasoline. It is possible however.

One main advantage is the ability of the offspring to take advantage of the parent's resources while the young tree is growing. Trees growing from seeds are limited to the resources in the seed to get their start; trees from root-shoots can borrow from the parent until they can make it on their own. Think of a redwood: most of their reproduction is asexual. Their seedlings have little chance in the deep shade of a forest, but when root-sprouts can take advantage of resources from an already-mature tree getting light in the canopy, the sprouts can grow 3 feet a year.\nSome trees can also root-sprout or stump-sprout if they are cut or fall down. That's another big advantage--to be able to reproduce almost after you're dead.\nAnother advantage is that an asexually reproducing tree is assured of a good environment for its offspring--if it has enough energy to reproduce, it must be doing well. Of course that advantage is shared by non-dispersing sexually reproducing trees.

Fossil fuel is the primary alternative due to price.  As the price of fossil fuel rises, a number of alternatives become more attractive.  Wind energy is an option, but it is not likely to be the main alternative.  Nuclear has a long history for power plants, but very limited short term potential for other applications.  Solar holds tremendous potential.  Gas to liquid technology and coal to liquid technologies are the most likely alternatives in the 5 to 10 year range.  Hybrid cars will help for a while, and in 15 years hydrogen fuel cell cars will start to have a MAJOR impact.

Biopower..\nCooking fat needs pre heating as mostly it is solid at ambient temperature.. Therefore it won't flow thru the pipes.\nBut generally with some good design then biopower could be as reliable and just as quick to start up as fossil fuels.\nIt all depends how you generate the electricity.. Steam turbines are more efficient than internal combusion engines and depending on the cost of fossil fuels could be equally as cheap.

A plant uses photosynthesis to produce glucose.\n\nSome of the glucose will be used in respiration to generate energy.

Recycling and pollution control. The fuel production company generates CO2, which it then feeds to plants. The plants absorb CO2, reducing the  company's CO2 emissions. In addition, the plants convert the CO2 into cellulose, which can be burned as fuel.

the pros are that it is a renewable resource, the downside is that the mileage is lower than using gas. i have no idea why it isn't in larger use now, even though the mpg is lower, it would result in energy independence if there was widespread use of ethanol.

Pros: very abundant\nVersitile (can be converted to gasoline if need be)\nCheap\n\nCons: dirty (contains sulfates that when burned cause acid rain)\nIncomplete combustion creates carcinogens\nWaste product CO2 is a green house gas.

pros: effective reutilisation\nless energy consumption for reuse\n\ncon:\n more time\nmore equipment\nmore hassle

Advantages\n\nCan use when there is a scarce of electricity\nJobs for lot of people\nCan use in major research activities\n\n\nDisadvantages\n\nVery Dangerous if leaked\nCan cause thousands of human loss if handled incorrectly\nMay bore new types of diseases if leaked\nNeighbourhood people are always at risk\nNeed a large area to construct\nLot of people need to be on site for maintenance\nThreats from other countries if used inappropriately\n\nBYE

Not quite the answer you are looking for but, there is a great article in this month's Popular Mechanics about the truth about BioFuels.  It has a great comparison of the above...

Renewable energy resources may be used directly, or used to create other more convenient forms of energy. Examples of direct use are solar ovens, geothermal heating, and water- and windmills. Examples of indirect use which require energy harvesting are electricity generation through wind turbines or photovoltaic cells (PV cells), or production of fuels such as ethanol from biomass (see alcohol as a fuel). A parameter sometimes used in renewable energy is the tonne of oil equivalent (toe). This is equal to 10,000 Mcal or 41,868 MJ of energy.\n\nIn a sense, renewable energy may be categorised as free energy, although most renewable energy sources would not normally be called "free energy". In engineering, free energy means an energy source available directly from the greater environment and which cannot be expected to be depletable by humans. Renewable energy development is concerned with the use of renewable energy sources by humans. For aspects of renewable energy use in modern societies see Renewable energy development. Modern interest in renewable energy development is linked to concerns about exhaustion of fossil fuels and environmental, social and political risks of extensive use of fossil fuels and nuclear energy.

It all depends on the area where you live. Like people in Florida would benefit most from Solar energy. People living near dams would benefit more form water energy. Wind energy would benefit people who live in the mountains. It all has to do with the geography of the land. But dealing with fuel options... I'm stumped!

The quantity and quality of a resource is determined by whether it is a renewable, non-renewable, or a flow resource. \n\nRenewable resources, such as plants and animals, can replenish themselves after they have been used if their physical environment has not been destroyed. If trees are harvested carefully, a new forest will grow to replace the one that was cut. If animals eat grass in a pasture to a certain level, grass will grow again and provide food for animals in the future, as long as the carrying capacity of the land is not exceeded by the pressure of too many animals. \n\nNonrenewable resources, such as minerals and fossil fuels (coal, oil, and natural gas), can be extracted and used only once. \n\nFlow resources, such as water, wind, and sunlight, are neither renewable nor nonrenewable because they must be used as, when, and where they occur. The energy in a river can be used to generate electricity, which can be transmitted over great distances. However, that energy must be captured by turbines as the water flows past or it will be lost.

you mean a)productive=producing crops or b)producing just any biomass?\n\nif you mean b) : it could be too salty, too dry, hot, frozen, flooded, etc or conditions too changeable\n\nif you mean b), you can add: too steep slope, or scattered with boulders and rocks so you cant make it into a field, thickly covered by vegetation that is hard to remove or simply too weedy.
