What are some futuristic uses of hydroelectric power?

I know that we use it now for powering homes, factories, etc. And I know that we will probably use it even more in the future. But I am wondering if there are any cool, unique, and specific concept designs (things thats people have already thought of and I can find information on) i.e. a hydroelectric car or a hydroelectric house.

formula for the amount of energy produced through hydroelectric power per certain amount of water?

is there a formula for the amount of energy produced through hydroelectric power per certain amount of water? if so please let me know. thanks in advance.

Why is hydroelectric power better than geothermal?

Hey I was wondering, Why is hydroelectric power better than geothermal? I’ve been hearing that it’s better of the two, but I need some resources.. Please help. Thanks

Would Hydroelectric power be more efficient than any other power? what are your opinions?

I’m researchig Hydroelectric power (Power generated through Dams)
and i want to hear opinions from average people,
wether it would make a difference or not?
Is there any or many dangers about hydroelectric power?
What do you know about it??

Is hydroelectric power as green as is claimed?

Hydro is often described as a “clean energy” source. However, not all agree that it is so clean after all.

Do you agree or disagree that hydroelectric power is a clean form of energy?

biofuels……?

If you had an Ethanol (or biodiesel, or any other biofuels) gas station at any reasonable distance from where you live, would you be willing to use biofuels instead of common fossil fuels? Why?

Example of prices are:
Gas, $4.12
Ethanol (or another biofuel), $3.22

Thank guys

Should Obama repeal Ethanol Fuel laws and tariffs?

Environmentalists promoted biofuels in the 1990s as a “green energy” alternative to oil and the agricultural lobby pushed hard for legislation to promote it. Recently, with strong government backing, production and use has increased many-fold. The biofuel boom is now removing crops and cropland from the food system and bidding up food prices dramatically.

In 2007, producers converted an estimated 80 million tons of grain into biofuels, including a quarter of the US corn crop. In 2008, grain for biofuels will pass the 100 million tons mark. Since less than a quarter ton of grain feeds one person for a year, biofuel production in 2008 will, in effect, remove the food for four hundred million people from the marketplace. Biofuel apologists argue that humans do not eat the corn used for ethanol production. But such arguments are misleading. The corn is used for many food purposes, especially feeding animals that people eat. And its cultivation displaces wheat and other important food crops.

Not all biofuels are equally efficient as energy converters. Brazil points out that its major biofuel – made from sugarcane – is much more efficient than corn ethanol made in the United States. And Indonesia promotes its palm oil biodiesel as efficient also. None can deny that corn ethanol, protected by a steep US tariff, is the least efficient in this product line. But all biofuels suffer from similar environmental and humanitarian problems. Brazilian and Indonesian biofuel plantations have been established by clearing rainforests and planting in fragile soils and ecosystems.

As new and definitive reports set out the ills of biofuels, most analysts have concluded that crop-based biofuels (using corn, oilseed and sugar cane) are unsustainable drivers of the food crisis. Even “second-generation” biofuels (using agricultural wastes, switchgrass, jatropha and wood chips) now appear to have serious problems.

The Bush administration in Washington has brushed off critics, saying that biofuels only contributed 3% to recent grain price hikes. But in April 2008, a Word Bank assessment concluded that biofuels are “the major cause of the increase in food prices,” responsible for more than 50% of the overall price increases. The Bank suppressed the report, apparently for fear of angering the Bush administration, but the Guardian newspaper eventually leaked it in July 2008.

Biofuels are now heavily subsidized – about $1.50 per gallon in the United States according to some estimates – and they are mandated by law as a percentage blend in gasoline and diesel fuel – in the US as well as the EU. The mandates call for further regular increases in the percentage blend. Current US legislation requires a five-fold increase by 2022. But the policy momentum may be slowing. The UK government released the Gallagher Report in July 2008, a study that proposed a reduction in blend targets, because of serious questions about biofuel impact on food prices and environmental sustainability. The European parliament has also called for a downward revision of targets.

A number of other studies have shown that biofuel production is contributing to soil erosion and serious depletion of water resources. Ironically, biofuel production requires a great deal of petroleum – nearly as much as it replaces in the case of corn ethanol. So it fails to solve the problems of high petroleum prices and climate change as promoters claim.

Big companies are rushing into biofuel production to capture the big subsidies, creating a powerful lobby to expand mandated use and boost subsidies still further. Unless governments reject these pressures and heed the urgent warnings, biofuels will rapidly worsen the food emergency.

Gas hit $3.65 per gallon today in WV…What is it going to take to make a significant change?

The price of gas is higher than I have ever seen it. I live in WV and I’ve never seen gas at $3.65 per gallon. I know there cannot be that big of a shortage or that much of a demand. In either case our freaking government could (at the very least) come up with a plan to ease the suffering of everyone who cannot continue to pay these outrageous prices. I know a lot of people will say..drive more efficient cars (hybrids), contact your legislator, make more money, whatever the H. Well that is not a long term solution or even a half way intelligent answer. So, how bad do you think it’s going to get before it gets better? Are we headed for another Great Depression? Me personally, I’m planning to get diesel cars and make my own biodiesel, but that’s not going to stop the rise in gas or the oil companies posting record profits. Just so we are clear, I do think Dubya Bush is making a crap load of money off the high price of gas/oil.

Did you know about this?

“‘Most of the oilseeds are used for food here, so that puts biodiesel in an immediate disadvantage, price-wise,’ said Adams, the school’s director of the Faculty of Engineering Outreach Service. ‘But it’s an excellent fuel and burns very cleanly. And diesel engines are inherently more efficient than gas engines. It’s good for our country and our farmers.’

Those sentiments were expressed a generation ago by Carter, who ran the family peanut farm before being elected Georgia’s governor in 1970.

‘If our country had followed the policies he laid out then, we’d be far more advanced today in terms of energy independence,’ said Johnson. ‘President Carter gets to see part of his vision advanced by way of a biodiesel plant in Plains, Ga.’”

BIODIESEL IN THE UNITED STATES:
- 105 biodiesel plants are in operation
- 77 are being built
- 225 million gals. were blended in 2006
- An esitmated 65 million gals. annually will be added by 3 facilities being constructed in Georgia, by 2010

What do you think of this progressive plan to address issues in America?

Reform healthcare because alot of our budget is sucked into medicare costs.Legalize Pot because it was illegalized through stupid racist rhetoric in 1937,tax it, earmark it for education.Reform education with the hundreds of millions if not billions of new tax revenue
Utilize the hemp stalk (the plant which bears marijuana) that is grown for Biomass production for a new energy agenda – essentially bring the middle east into the mid west. Which means you have to overhaul the auto industry’s production and mandate new vehicles be biomass ready by year 2011 or 2012 (henry ford designed the model t with hemp oil fuel in foresight). Provide tax incentives for people to convert cars and fuel stations to offer both fossil and bio fuel (create competition for fuel- Biomass or Fossil). Make sure the biomass infrastructure is government regulated for 15-20 years, so its profitability could fund the infrastructure implementation of mass transit across the country (much like Europe’s system).

Hydroelectric Power – what are the costs?

What are the costs of building and then running a large Hyrdroelectric dam? I need pretty detailed answers as I’m writing an A-Level report and really struggling on this point.

Basically, I need someone to tell me:
- the cost of building a large scale dam in a country like Canada.
- The running costs
- How long it would take to ‘pay for itself’
- How much electricity would cost to the consumer

If anyone can help here please do!

Thanks very much ^_^

the hydroelectric generator can supply upto 100 units of power per day at a constant marginal cost of 1 cent?

Per unit. the steam gen can supply any additional power that is needed at a constant marginal cost of 10 cents per unit. when electricty costs 10 cents per unit, demand is 200 units per day..
How much should govt charge for electric power????????????

how much does a hydroelectric dam cost to build?

In the large scale, large river, large power output.

what are some good solar, wind, and hydroelectric power stocks?

that cost less than 10 dollars each

Electric vs. Internal Combustion?

I need to know the pros and cons between electric vehicles and Gas powered vehicles.

How much do the electric carts for the handicapped cost approximately?

After church on Sunday, several co-workers and I had a few drinks and went to Target to drive the electric carts around the store and parking lot. The key is to slump over and look retarded or play with our nipples when an employee is looking. I think they know we aren’t disabled but don’t say anything in case they are wrong. Anyway we got a little too rowdy and started holding them while we did burnouts on the sidewalk. One of them broke(piece of junk) so I got in it and a friend of mine pushed it over a 2 foot curb and it nose dived and broke completely. Now those assholes are making me pay for it! How much do they usually run?

Are ordinary people allowed to use the handicap electric carts at Walmart?

Today my friends and I went to Walmart and one of my friends got on one of those handicap electric carts at Walmart. He wasn’t hurt or obese, and the workers didn’t say anything. Are people allowed to use them even if you have no physical problems.

How many of you park in handicapped spaces or ride electric carts and nothing is wrong with you?

Some of us do inconsiderate stuff consciously while others don’t think about that they are taking away from people who really need. Ex: Parking in Maternity/Handicapped spaces, riding electric shopping carts because they are lazy, using handicapped bathroom stalls/fitting rooms because they are bigger, etc.

I would like to build my own RC Electric car, what companies make kits?

I’ve been looking for a RC Electric car kit and i can’t seem to find any company that makes the kit that are not already built. I would like to buy a kit that I assemble myself. Please let me know what companies offer this.

Any companies that sell electric car kits?

They are kits that help you change over you car to an electric engine. I tried looking for some myself, but I can’t find any! I just need the company name and information about the kit. Anything will help!

P.S. do they even sell them anymore?

Do people REALLY believe that electricity comes from foreign oil?

Essentially no US electricity comes from foreign oil. ALMOST NONE. as in LESS THAN ONE PERCENT (<1%)

US power plants are:

Hydroelectric (No foreign oil, obviously)
Coal (No foreign oil, obviously)
Natural Gas (Natural gas in the US is 100% domestic)
Nuclear (No foreign oil, obviously)
Solar (No foreign oil, obviously)
Wind (No foreign oil, obviously)
Geothermal (No foreign oil, obviously)
Biofuel (No foreign oil, obviously)
and a little tiny bit of petroleum, SOME of which is foreign based during SOME of the year (based on domestic production of heating oil)

Do People really think solar etc will reduce our dependence on foreign oil when we don’t use foreign oil to produce electricity??
@SCOTTS

No

Says Reality

To my knowledge Fox hasn’t commented on the subject.

Please do point to a power plant that burns foreign oil.
@NAUTILUS

The question is about domestic electricity production and if “green” power plants will reduce dependency on foreign oil (Which they obviously will not)

Talking about the other things we are hooked on that involve oil is off topic and moot.
@ANDY
