We are currently using our non-renewable resources faster than they are being made. They’re mainly used for cars and transportation. A lot of people are forgetting about the fact that someday we will run out of these resources and it will be thousands of years before we have a sufficent amount again. I realize that many people are finding other sources, but many people still use the non-renewable ones. What are we going to do when there’s no more non-renewable resources in the world?

once our planet runs out a non Renewable rescorces we would have to rely on other reknewable rescorces, for exsample oil is alreadey being replaced with materials like vegitble juices.

How to calculate the Energy saved by capacitors and do sine wave inverter save energy?Maybe the amount of energy saved by using power savers in percentage and how to calculate.

capacitors don’t save energy, they store it for a temporary period.

No, an inverter wastes energy. They are 90% efficient at best, which means 10% is lost as heat. That applies to sine wave or other types.

Re capacitors, if you are talking about that scam of putting a device on your utility lines to change the power factor, that does not save any energy, nor any money, as the utility charges you for real power only.

Nuclear power in itself is not expensive, however, it has a larger capitol cost that, it is known, interferes on taxes. How would an increase of Nuclear weapons (not power) effect our taxes?

They’d have to pay for the weapons somehow. I’d think the military would need a bigger budget, hence, larger taxes.

Today BP will try to choke off the oil gusher at the bottom of the Gulf of Mexico by force-feeding it heavy drilling mud and cement. Senator Harry Reid admitted “waiting with bated breath” to hear the results of this attempt to stop the leak that started more than a month ago. But Reid also acknowledged the opportunity that this terrible disaster has presented the country: “This is an opportunity for us to move away from fossil fuel, to do a better job of looking at this Renewable energies that are available to us all over this country — sun, wind geothermal.”

A new wave of technologies is on the verge of producing Energy that’s clean, Renewable, and most importantly, affordable.

As a month-long Nuclear Non-Proliferation summit in New York draws to a close, participants are still debating how best to achieve a nuclear-weapons-free zone in the Middle East.

The problem at the heart of it all is Israel, a country with an undisclosed but known nuclear-weapons capability.

Israel decided not to come to the US meeting, knowing it would face scrutiny and criticism.

Meanwhile, while it is still not clear whether Iran really wants or intends to militarise its fledgling nuclear industry, the potential has already increased tension throughout the Middle East and led to warnings of a new arms race there.

Recep Tayyip Erdogan, Turkey’s prime minister, has been among the most outspoken on the issue, saying many times that it is unreasonable to call just for restraints on Iran, while not dealing with the nuclear capability of Israel.

But the one issue that Erdogan never mentions is Turkey’s own nuclear weapons stockpile.

As a founding member of Nato, and a strategically-located state, Turkey is one of five Nato countries with nuclear weapons stationed on its soil.

And as many domestic analysts are now observing, this evident contradiction is no longer helpful for Ankara’s's newly neighbourly and avowedly peaceful foreign policy.

i need help with this question:

how are Renewable and nonrenewble resources alike?

anyone that could help that would be great. thanks.

that they are both natural resources and come from the earth!..

can not think of anything else…

I don’t know much about physics, but I know that energy cannot be created or destroyed. So if this is the case, what happens to all of the energy stored inside, say, a person, if they were to die? Think about it, there’s all sorts of like, emotional energy, it takes energy for all of the brain processes and such to occur, what happens to it all when the person dies? Could that be what a "soul" is?

You are 100% right, energy cannot be created or destroyed. But it can be converted. When life ends, everything that made up the corporal essence of that life begins immediately to decay. Nourishment and life process (inspiration, electro-chemical activity, osmosis, etc.) grind to a halt. Not all of them stop immediately, some take time to grind to a halt.

As the corporal essence decays, the electro-chemical energy that represents potential useful energy begins to convert to other forms of energy. Some of that work energy will convert to a form of energy called entropy. This is simply a form of energy that can no long be invoked to do useful work. Our universe is in a state of net positive entropy, which means it will eventually run down and stop (at which time its temperature will become absolute 0 deg K because temperature of any level represents the other form of energy called enthalpy).

Enthalpy is the kind of energy we can use to cause a change or do work (like moving something). One obvious form of energy conversion is when the chemicals of decayed flesh are absorbed into plants that are then eaten. So the eater gains electro-chemical Energy to do whatever work it is able and inclined to do. In this case, the energies are changed from one electro-chemical process to another, but they are both electro-chemical energy of which, the eater will further convert into work.

As to the soul…this is a matter of faith, not science. There is no scientific evidence of a soul. But if there is one and the converted energy you allude to as being a soul is that soul, then its ultimate end is entropy…useless energy. That is the nature of a net positive entropy…a rather ignoble way for souls to end.

My question has to do with popular cultures portrayal of radiation. We are all aware of the effects fiction usually describes: growth of extra limbs, superpowers, zombification, extreme mutation (turning people into giant monsters), induced cannibalism and insanity, etc.

Are any of these things true? I’ve been playing Fallout 3 and almost all of these mechanics are present. What would the effects of Nuclear fallout really be?

None of the ‘popular culture’ symptoms of radiation exposure are true. The most likely result of an exposure to radiation below about 25 RAD is nothing – your body has the capability to repair damage at that level or below. Above 25 RAD to about 400 RAD, blood chemistry changes – would be detectable, then the damage would start to be systemic – your immune system would break down – at 450 RAD, about 50% of the population would die without treatment – mostly from opportunistic infections because of the breakdown of your immune system – above about 1000 RAD, most people would die – again of infections (even benign bacteria would kill you – as your immune system couldn’t keep it in check.) Above 5000 RAD, your nervous system dies – it will take a few days, but you would shut down systematically.
Those are all acute effects of a large radiation exposure such as from fallout. If you were exposed to radiation above about 100 RAD and survived, you might develop cancers – leukemia or thyroid cancers predominantly, which might take 20+ years to show up. Children are particularly susceptible to such cancers as their cell replication rate is much higher than adults – essentially the higher the cell replication rate, the more susceptible a cell is to damage from radiation which could cause cancer.
No zombies, no extra powers, extra limbs, etc. Makes for nice stories, but grossly untrue in reality.

Can Renewable Energy truly be good for the economy, and how so?

Renewable energy can be good once we have a storage system to store the sun’s, wind’s, etc’s energy and use it when we need it.

It is good for the economy because it is getting more and more expensive to dig up conventionals.
