iwhat are some not-so-well known alternative energy sources. google it and you don't find much. when i google alternative energy i usually get:
hyrdoelectric energy
photovoltaic energy
wind energy
geothermal energy
ethanol
biodiesel
biomass
tidal energy
hydrogen fuil cells
passive solar

besides that i know of:
microbial fuel cells
artificial photosynthesis
syngas
biogas

what else is there?

I'm looking for a number in terms of money, a source would be nice...thanks
if possible can u give me what the "tipping point" for earth is, if we don't switch to alternative energy sources

I'm thinking about getting my Associates in Applied Science for Alternative Energy and was wondering what kind of jobs I would be looking at. Any ideas as to what jobs require this?

I'm thinking about getting my Associates in Applied Science for Alternative Energy and was wondering what kind of jobs I would be looking at. Any ideas as to what jobs require this? What would the pay be? How much more would I make with a Bachelors?

To reduce our carbon footprint.

Like (example), I would choose biofuel, particularly vegetable oil, to power RV's.

need some answers for a class pls
need this for class pls and if you can give me some good websites thx

Solar, wind, tidal, hydroelectric, geothermal, biomass or biofuel, and nuclear?

Would hydrogen be one? What else is there!?

what will happen to the supply of corn's substitute such as soybean? What will happen to the price of corn oil? How does the price elasticity of demand for corn oil influence the quantity-demanded of corn oil and the Total Revenue earned by sellers of corn oil?

Why?

Can anyone provide me with some good logic or actual facts on how BRIC (Brazil Russia India and China) helped us switch to alternative energy?
I get that they increased pollution, but what else?

The idea is that the West in general and the U.s, in particular, should be more self-sufficient in energy resources to reduce dependence on oil imports from the Middle East

Are there any through Vanguard? (I think they only have an energy fund with 80% in oils, yuck!)

I've got 00 to invest....would like alternative energy index funds...with low expense ratio...and good returns.

What do I buy and where do I buy it through?

I have just got this assignment and i have to make an alternative energy vehicle, it can be a plane, car, boat etc (miniature). I really want to get an a or real good mark so do you have any suggestions or websites etc to help. Thanx

I'm doing this for a project and its due tomorrow i need the argument which i have, but i need evidence to support that global warming was the cause.
thanks

I took an AP Environmental Science class and I fell in love with the idea of harnessing alternative sources of energy to help the world. But I have no idea what major I would choose in college. I really want to go to UCSD by the way thanks for the help:)

I work a lot and sometimes I literally go to work 7 hours after I get off the night before. Sometimes my shifts are as long as 10 or 11 hours in length and I usually consume 1 or 2 energy drinks to wake me up and when I need to power through to the end. I know how bad energy drinks can be if consumed regularly, but its the easiest way for me to wake up. I hate coffee, and I just need an easy alternative.
Thanks!

I'm just curious what sorts of physics topics scientists and engineers working on alternative energies would be familiar with. Thanks!

...?

Alternative energy is electricity.
Oil isn't.

So how does alternative energy trade off with electricity?
Er, yes, wrong forum...noticed that as I posted it. But answer, please!
