If you plan to use 500 watts per hour of electricity how many solar panels and batteries will you need?

Assuming that you plan to use car batteries or something similar(deep cycle), plus an inverter (or many), and solar panels? And what kind of solar panels should you get? What will the approximate cost be for such a set up?

Why not Solar Energy for homes? How can I get Panels? Difficulties with them?

Does anyone know why people don’t do this? There is a house that I saw on the news that is so energy efficient that the Solar panels paid for themselves in the first year. Plus on occassion the electric company has to buy the surplus electricity produced back from the home owner.

Anybody have an idea for a project using solar panels?

The Earth needs to be saved, so a lot of facilities are going green. i need a summer project that uses solar panels to generate some sort of electricity. It’ll be a small step in saving the Earth, and plus, it’ll be a good summer project.

How come no one is working on solar powered cars?

Can we sue the oil companies for stopping ideas that need to be made? Why can’t the whole car be made of an unbreakable solar panel ? Screw the oil companies we are tired of paying!

If electric and solar powered cars have been made, why havn’t they replaced the gas powered cars?

As major car company’s know, gasoline and oil is becoming very scarce. Electric cars have been made, why doesn’t the car company’s or whoever makes them sell them to good people of earth. Do they want it for their selves while we pay hundreds for gas. Think about it.

Who knows anything about solar powered cars?

I’ve actually seen a car at a show once that was covered in solar panels. Does anything know how the engineering of these cars is going, and whether there will be a solar/fuel hybrid car sometime in the future?

Do Concentrated Solar Plants heat Oil to high temps which create steam which power conventional turbines?

CSP does not rely on the sun to create power. They concentrate the sun to a fine poit which focuses on a line of fluid, heating it to a very high temperature, which creates steam which runs a turbine. Same as a cola plant accept instead of coal creating the steam, solar does the job. So you don’t calculate the amount of power based on standard solar power calculations as you do with Solar PV roof panels. CSP is very efficient. Over 100 applications were made during Bush’s term and all turned down? Why? It will reduce our reliance on Coal, which is profitable to coal manufacturers. The Oil/Coal/Gas/Nuclear industries do an excellent job of making sure most people don’t understand the tru viability and advantages of Renewable Energy and all the different options. Why? They don’t want a power shift away from the products they make a bundle on.

How would I get a job in the energy business in Brazil?

I have over a year of experience in the energy business in the states, and i want to work in ethanol, bio fuel, wind, or solar power, or anything that will give me access to work with the top people in the field, because I believe it will be the wave of the future. I also speak a little Portuguese.

solar energy question?

how hard would it be to make one portable 120 volt ac 60 Hz two outlet plug from solar panels? it would be used on job sites for power tools with medium length extension chords and other portable appliances.
this application would tyicaly draw a lot of amps.
ouch! ok. just wondering. there are no dumb questions, right? right? nevermind…but thanx. actually i was just thinking in terms of not having to use temp poles.

5 Questions need help please?

If you were asked to describe metals and magnetism you could say

non–paired electrons spin in opposite directions in all metals, creating a magnetic field.

metals are magnets because they have more electrons than non–magnetic materials.

metals can become magnetic if they have many spinning electrons that create magnetic fields.

the electrons in some metals pair up to create a magnetic field.

Question 2 (Multiple Choice Worth 2 points)

Which statement is true regarding copper’s ability to conduct electricity?

Copper is a good conductor of electricity because its atoms have a loosely held electron in their outer shell that is able to move freely to other atoms.

Copper is a poor conductor of electricity because its atoms are held in positions that cannot move.

Copper is a good conductor of electricity because its atoms have electrons that are tightly bound to their shells and will resist movement.

Copper is a poor conductor of electricity because it has a free electron in its outer shell that will flow to other copper atoms.

Question 3 (Multiple Choice Worth 2 points)

Which statement best describes the relationship between metals and magnets?

All metals are attracted to magnets because they are able to create their own magnetic field.

All metals are attracted by magnets; this is why we call metals ferromagnetic.

Magnets do not have a magnetic field so only some metals are attracted to them.

Only some metals are attracted by magnets; these metals are called ferromagnetic.

Question 4 (Multiple Choice Worth 2 points)

Which of the following best describes the use of a nonrenewable resource?

In the state of Texas, you can find miles of windmills that are used to generate electricity.

Natural gas is a great alternative to electricity for cooking.

The electronic signs along the highway are run by solar power.

Question 5 (Multiple Choice Worth 2 points)

Human populations all over the world burn fossil fuels to power cars, planes, and generate electricity. Select the statement that best describes the long–term global effects of this behavior.

Burning fossil fuels pollutes the environment and our heavy reliance on them creates a long–term problem because they are not a renewable resource.

Countries will not need to spend money on investigating other sources of energy because fossil fuels are abundant.

Fossil fuels burn clean so the pollution problem is not really a source of concern for the future.

As populations increase, the need for fossil fuels will decrease; therefore, there will always be an abundance.

Why did Obama say the Stimulus would create Green Jobs when 80% of the money when to overseas manufacturers?

It’s creating jobs alright – for overseas manufacturers that is – Obama conveniently left that part out.

http://abcnews.go.com/WN/wind-power-equal-job-power/story?id=9759949

Wolfe@ are you calling ABC a liar?
Yes – 80% of “Green Energy” money went overseas – I know it’s not clean in my question.

Why did Obama’s energy dept. try to discredit a Spanish report criticizing wind power as a job killer?

The Energy Department worked closely with the wind industry lobby to discredit a Spanish report that criticized wind power as a job killer, internal DOE e-mails reveal.

The e-mails obtained from a Freedom of Information Act request show how, starting last April, lobbyists at the American Wind Energy Association became alarmed that lawmakers were citing a study by Spain’s King Juan Carlos University. The study found that Spain’s massive investments in wind power cost 2.2 jobs for every “green” job created.

But the Spanish study isn’t the only evidence that green jobs come at a stiff price. President Obama in January announced $2.3 billion in grants that he said would create 17,000 cleantech jobs. That’s $135,294 per job. California’s nonpartisan legislative analyst said Monday the state’s climate law will likely cost some jobs.
