Alternative Energy Sources

countries like usa and european ones. are they building wind farms and that. what ones?

and also what is the highest renewable energy source for one country?

Yes, a lot of countries are wasting money on wind and solar.

The only ‘renewable’ sources of power that are actually reliable enough to be worth having or hydroelectricity and geothermal power but not all places have the geology needed for them and hydro has something of a bad reputation (well deserved given the environmental impact and what happens when dams fail).

As for who uses the most renewables, Norway has a lot of hydro and Iceland uses geothermal extensively. Denmark has managed to get about 20% wind capacity but hasn’t even shut down any coal power plants and at the moment pretty much just sells the wind power to Norway really cheap where it’s used to pump water uphill.

And What's a Good Experiment to Prove This?

I would say by comparing how many Watts either source could produce under efficient conditions. Once you've got the energy they're both going to move an object in an equal ratio; it doesn't matter where that energy came from.

In some manner it does matter what we're talking about moving though. If we're talking boats that's completely different from cars or something else.

I know that Germany is the leading nation in prodcucing electricity, etc from Wind energy. But the govt should have passed some laws taht would encourage wind power right? Also, are the ppl taht use wind power given subsidies, etc
Is there smth on the internet where i can find laws and regulation, etc related to this?
Thanks in advance for ur help.

Yes.

The main law is one which says the electric power companies have to buy any excess power generated by someone who builds a renewable energy source.

Some States in the US have similar laws. But in Germany it's nationwide and the law specifies a price which is reasonable for the power companies while being enough to encourage construction of renewable energy sources.

1. Solar energy is not cost effective due to the cost of equipment and the cost fossil fuels needed to create solar energy cells in the first place. If you were to install solar panel on an average home in Phoenix AZ and you calculated the cost + fossil fuels used in creating the solar equipment it would take from 5-8 years to show a profit. Other cities that get less sun than the desert would take even longer and the cost would go up as you also calculate Maintenance dollars.

2. In order to generate enough energy to effectively curb our need for fossil fuels would not be economically prudent or reliable with the given solar technology as we know it today.

3.Hydrogen fueled cars and and big trucks is the main target of defeating the need for foreign oil. Solar energy will never be able to generate enough energy to supply hydrogen refueling stations.

Yes.

I have been looking at this myself. I like two smaller and easy ways to get started.
One is to have a solar system put in and tie it into the grid. There are solar SHINGLES now, that look and are applied to the roof like regular shingles,(with normal wear) and are wired together and then tied down through the roof to the grid connection. If you need to reshingle anyway, and you are in a state that pays a rebate for renewables and then sell energy back to the power company when not using it yourself, plus not having to pay for battery system - the system can have a true breakeven or even a lower cost.
I also would like to have some small marine wind generators, to place in 'wind tunnel' type locations around my property. Although my region does not have strong enough winds, I think maybe some locations might have a better chance for a smaller wind system.

For debate team we are debating the resolution that tax credits should/should not be given for using renewable energy. Please help by posting websites for and against it!

Thanks

I don’t know any web sites but I can tell you why I don’t like the idea of tax credits for alternative energy. Tax credits are a penalty against conventional energy sources. If the alternatives are so great they shouldn’t need tax credits to make them competitive. Using tax credits to make alternative energy able to compete with conventional sources doesn’t encourage the companies that make alternatives from improving their products to compete in a free market. The tax credits have to be replaced with some other source of revenue or savings. The term “savings” is not known to the government so they raise taxes or increase the deficit. Their is also the administrative cost of monitoring the tax credits. That means more government. Let the laws of supply and demand work without government interference

I NEED INFORMATION FOR A SCHOOL PROJECT….

DOES ANYONE KNOW ANY GOOD WEBSITES WERE I CAN GET INFORMATION?

I Hope you're not just starting a project due tomorrow….try going to google and keying in solar power benefits

Benefits - after installation it is free and readily available;
extends workday, improves health, reduces fire risk, not polluting, renewable and easily improved

I like the box fan idea, can I just reverse the blades to reverse the motor and create energy instead of use it? Then what?

This is a very in depth project on which you are embarking. There must be a regulation stage and a protection stage at the very least.

Regulation stage:
AC current regulation to 1phase 60hz 120VAC

Protection stage:
Over voltage and spike protection

Remember that you will only have power when your blades are spinning. Also, those fan motors don’t take a ton of power to turn. They will correspondingly only output a small amount of power. Check to see if it can even function as a generator without overheating and burning out.

I have read articles about wind, solar, alternative fuels, and hydro power in The Mother Earth News. Who has used these alternative resources?

I have burned vegetable oil for about a year in various burners. Narrowed it down to simple easy clean exhaust. And applied it to a few household chores. I think I would sum it like this. If everyone burned veggie oil. Theres not enough. Geothermal should be mainstay temperature regulation. Hot water, cooking and clothes dryer activities are next. You only need so much hot water at one time. Make that much. Cooking make mega meals and freeze some, eat and eat some later. Lots of various savings here. Clothes, air dry if possible or dry selected items.
