I’m doing a video for school that has to persuade people to use nonrenewable resources such as wind or solar power. What is a good song that is very similar to One Tribe by the Black Eyed Peas?
Thanks!

I’m asking this so I can complete the Eco- Action Interest Prodjet and to tell people about how it cuts down on personal consumtion of nonrenewable resourses.

I can’t answer the solar but the wind turns a fan (just like a fan would make "wind") This moves copper in out of a magnticfiled giving it a current which has power.
Hey guys. I would like to begin heading up a commitee in my school that focus’ on making our school greener. I would like to present some facts to them and see if it would be a possibility to have wind or solar energy at our school. I live in northern michigan so it gets very cold, if that makes a difference.
Could you please tell me all you know of solar panals and wind turbines? Another big factor is the cost – we have about 90 kids per grade k-12. thanks
The current solar panel technology is actually more efficient in cold weather. We installed ours when it was -10 degrees (F) and they generated 120% of their rated capacity. So your cold weather is not a problem. However, you may wish to consider whether the number of sunny days warrants a solar generating system, which tends to be pricey.
As for wind, it’s also spendy. You don’t want to mount it on the roof, because the vibrations will transfer into the building. So you need a separate tower for the turbine. We set up a 350 watt turbine on a 45-foot tower for about $1,500. But it generates 24 volt DC electricitry, so it requires an inverter in order to provide 120 volt AC power used in most buildings. Add another $4,000 if you want it to reduce your school’s dependence on fossil fuels. Otherwise, it’s little more than a demonstration project.
Solar also is typically set up to generate 24 volt DC power, so it too needs an inverter. Our 1KW solar system, with inverter and battery backup, cost about $16K. About $4K was for the batteries, which you wouldn;t need. And we got a $4K tax credit from the fed and state. Still, you’re in the $8,000 range if you include the inverter.
Alternatively you can try to see whether some of the school’s needs could be met with DC power, either 12 or 24 volts. A more practical, if less visible, approach might be to talk to your utility and see if you can contract to buy wind power (ours sells wind power for about 3 cents per KWH more than coal power).
Pls give me the sites that u found this information. Thk
Of total world energy supply – not just electrical generation – the breakdown is as follows:
Oil – 37%
Coal – 25%
Nat Gas – 23%
Nuclear – 6%
Biomass – 4%
Hydro – 3%
Solar Thermal – .5%
Wind – .3%
Geothermal – .2%
Biofuels – .2%
PV Solar – .04%
However, the use of solar and wind is increasing rapidly, so those numbers are almost certainly out of date. Wind is the most rapidly growing source; I’ve read in some places that it now contributes well over 1%.
Please only reply if you are an homeowner!
Besides the initial cost is there anything other reason you wouldn’t make the conversion?
it’s expensive

We need nuclear power plants now!
We need to drill for more oil now!
That’s "Wasting".
Now please put a "E" in column 1 by those sources below that are "Exhaustible" and a "I" for those that are inexhaustible. Put a "P" in col 2 for those that pollute, and "C" for those that are clean. Once done, mull.

Now answer these questions:
(1) Is it advisable to spend money on sources that are past their peak and dwindling?
(2) Is it advisabe to spend money on sources that pollute?
You decide.
Magnetic power generation is a good alternative right now. It goes beyond the concept of renewable & non-renewable energy and offers a simpler, clean ersolution.
The big advantage is, it eliminates the need for expensive solar panels & large areas of windmill farms.
Wind would be www.theKennedy’s.com
I have a small holding in quite a remote area & want to install wind or solar energy to cut the costs. I dont aim to be fully independant of the grid but just want to produce enough(perhaps only in summer if solar) to make a saving……how can i do this? I dont have a lot of money & ive been told that solar panels & wind turbines are expensive….any advice? I live in Eastern Europe( Slovakia)
The problem is that I am not a Slovak ( so am unsure how I would stand applying for government money) & renewable energy is a very new concept here. can you buy used solar & wind equipment? Is there a website that deals with this sort of thing?
There is no way to store AC power.
Help!!!
Wind power companies like to claim ~35% efficiency with their systems but the best recorded in operation is a maximum of 20%
Solar panels are incredibly inefficient with efficiency ratings of less than 2% of energy emitted adsorbed into energy.
Ambient /Reflective solar energy systems believe it or not are more efficient around 10% in adsorbing energy but the turbines used to turn the energy into electricity are only around 20% efficient so the number is only 2%
The trick with solar is to use the energy collected by the reflectors for heating something to get the efficiency of the heat created. that’s why they make good water heaters.
By the way gas and diesel piston engines are only 20 to 30 % efficiency, Gas turbine engines are around 50% but if used as a co-gen unit where both the engine created energy and heat are utilized their efficiencies go into the 90% level.
It’s part of the reason gas turbine power plants are so comon.
