Identify one energy source that is an altenative to using fossil fuels?

Question

and name a disadvantage and an advantage to usin this alternative energy

Answer 1

Water. Can be separated into Hydrogen and Oxygen. Hydrogen can then be used to power transportation, electric plants, etc. Advantage? Pretty plentiful stuff, and will re-cycle when used in this manner. Disadvantage? Highly voltatile, and hard to safely contain at this time, plus hard to safely dispense.

Answer 2

bio diesel from algae, and it's here now. Petrosuns algae farm in Texas just came on line, and it can produce 10000 gallons of diesel fuel per acre per year using brackish water.  that means if expanded or additional plants built it could meet all energy needs using the equivalent of 1/10 of 1 % of farm lands. so everyone is still fat and no drinkable water was used. Solix biofuels in Fort collins Co. is nearing start up as well as several other plants.

Answer 3

Biofuels; ethanol or vegetable oil.

Advantage: cleaner burning, lower in cost.

Disadvantage: reduces food supplies & drives up food cost.

Answer 4

electric...advantage is that it is cleaner and you don't have to worry about ever running out. I really don't see a disadvantage except that if you're using it for some things, they need to be plugged in either constantly or occasionally.

Answer 5

Solar

Answer 6

water turbines,

effective in turning the power of ocean waves into evergy

not everywhere is located on the coast

Answer 7

Man Power! (Your own muscles) Always conveniently located.  Available for dish washing, car washing, laundry, .  With available accessories (bike powered batteries) can be used for lighting and to run small electronics.  Modern conveniences are available only when you are

PS Water turbine do not need to be at the ocean only.  A small amount of water falling a long way or a large amount of water falling a short distance can also be used to turn water turbines

PPS  perrinediane  do you know that most electric is generated by fossil fuel?  You must mean electric generated by wind, solar,water or nuke?

Answer 8

Sunlight

Advantage- Easy to find

Disadvantage- expensive to get solar panels and equiptment to transfer sunlight into energy

Answer 9

Wind!  Or windmills.  Windmills get spun from the wind which, somehow, creates energy for people to use.

Disadvantage- it takes up fields and fields of land, and some people think they are ugly and are against the idea

Advantage- it is a great way to get energy, we know a lot about it, and some people like the idea and like the way windmills look (like me!)

Answer 10

Wind, Advantage: It will never run out disadvantage: there isnt always wind everywhere!!!

Answer 11

so many good answers including all I could think of.

Answer 12
