Does anyone know an alternative to gas/oil?

Question

I need to write an essay on helping the environment so a quick answer would really help. Thank You to anyone who answers.

Answer 1

The best alternatives to gas/oil is bio fuels. Particularly bio diesel, it can be made from any organic oil ( the best being the oil form algae 10,000 gallons per acre). It also can be used in any diesel engine with little to no modifications, and is much less polluting to the air.

Answer 2

biofuel,biomass,geothermal,solar,hydropo... power, tidal power,

Answer 3

Algae Biofuel

-With our current biodiesel feedstocks, like soy and palm, there’s no way we could grow enough to supply all of our transportation needs.  In fact, it would actually require twice the land area of the US devoted to soybean production to meet current heating and transportation needs.

-Algae, on the other hand, could supply all U.S. diesel power using a mere 0.2% of the nation’s land.

-Enough algae can be grown to replace all transportation fuels in the U.S. on only 15,000 square miles or 4.5 million acres of land.

- Algae is the highest yielding feedstock for biodiesel, producing 24 times more oil per acre, on average, than the next leading feedstock--palm oil at 635 gallons/acre/year.

-One company can produce 180,000 gallons of biodiesel every year from just one acre of algae. That comes to about 4,000 barrels, at a cost of $25 per barrel or $.59 per gallon.

-To put that in perspective, it takes 3,750 acres of soy to make the same amount of biodiesel at a cost of about $2.50 per barrel for 4,000 barrels.

-It is possible to use human sewage and wastewater from agricultural endeavors to enhance the growth of algae.  In fact, when done right, algae can double and even triple overnight with the addition of these fertilizers.

-Plus, as algae grows it absorbs C02 from the air.

-In addition, fertilizer for other food crops can be produced by using the leftover nutrients that aren’t used to make the biofuel.

Additionally we can use algae in E10 (90% gas and 10% ethanol) so we could start using it now.

Answer 4

theres ethanol,solar fuelcell used cooking oil

Answer 5

you mean, where can we get large amounts of "free" energy?

nuclear.

lesser amounts.

wind, solar, hydro.

even less, used cooking oil, tidal, geothermal.  (unless you're in iceland.)

batteries, hydrogen, etc are not sources, merely storage mediums.

water ain't it.  CO2 ain't it.  they're both products of combustion, not sources of energy.

bio is popular at the moment.

what's happened to the price of milk, vegetables, bread, etc?

very soon, it will likely be illegal to use food to produce bio-diesel.

maybe it's more important that people be able to eat rather than that someone have cooking oil to run their SUV.

Answer 6

Hydrogen, LP, electric, bicycle

Answer 7

ethanol.

soy.

leftover grease

water.
