Solar Energy

Please give a brief description of where each of these should be located on a farm and why.

Solar energy system:

Wind Power system:

Geothermal Energy system:

Thanks

Often solar panels are placed on a roof. If it is on the main house it will also keep the house cooler and electrical wiring lines will be shorter. But if they are on the ground it will be easier to keep the panels clean. In either place it should not be shaded.

A wind power system should be as high as possible and away from trees and buildings that might obstruct the flow of air, but you would not want to locate it so far away that electric lines pose too much resistance.

A geothermal system can be built in many different ways. If there is a pond nearby that is deep enough using this for the ground loops is the cheapest method. Trenches can be dug and a long loop system installed or most commonly two wells can be drilled and water will be pumped from one go through the system and be deposited in another well. The equipment that uses the loop will be located within the house.

Can someone give me a brief paragraph explanation on it?

Sure, but at what technical (grade) level?:

Sunlight contains energy in the forms of heat and light. As a radiant form of energy, direction, obstructions and size of the collection area all play significant roles in the amount of energy captured. As a diffuse energy source concentration and accumulation through storage are as important as collection. It has been converted to electricity directly in photovoltaic panels, indirectly in commercial thermal solar concentrators, through an intermediary like the solar energy stored in petrochemicals, wind and waves and hydroelectric power. Solar energy has been converted to heat our homes and hot water directly in passive home design and indirectly with thermal solar panels. Conservation is often a key factor in thermal solar energy storage and off grid solar electrical usage.

Some places rely on solar and wind energy right? To power their homes and such. How do they use energy in the night or when there is no wind? Do they have something that stores the energy like a big battery or something?

I have to “make” a green city and it will use renewable energy source including solar and wind energy. How would I make the wind and solar energy sustainable and not have shortages of power?

Small places, like a remote house or an island, might have batteries. A large place, like a city, would be connected to a "Grid", or electrical energy transmission system. If the wind stopped blowing, deep in the night, they would pull energy off the grid, from a nuclear plant, or coal-burning generation station, or hydroelectric project many miles away. A town on an island might have a large diesel generator.

I was having a debate with my friend about ways to make the environment better and to have a better energy reliance than oil. One idea that was floated was to have every street lamp based on solar power (with backup electrical grid power in case it rains or something) anyway, here was the debate which we need your answers to: Is it better to have a solar panel on each street light OR Is it better to keep the street lights as they are and just install solar panel hubs around the city that feeds into the electrical grid?

Until compact onsite electrical storage becomes practical, it’s better to have centralized solar power stations feeding power to the electrical grid, because 1) the wiring to the lamps are already in place and/or are necessary anyway for times of no sun, and 2) greater efficiencies and easier maintenance is possible at large solar power installations than with thousands of small solar collectors. However, independent "off the grid" solar powered devices is the trend. For example, through fuel cell technology, compact solar energy storage may become possible and practical, in which case high efficiency street lamps may go off the grid, thereby reducing wiring needs.

I came accross a new, proven and tested home made wind power system and solar power system which eliminates our electricity bills. It was written by a Renewable energy enthusiasts Michael Harvey the diy called Earth4energy. You can get your copy to save energy and help environment while eliminating your power bills.

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 was thinking of having it installed in my house but I still have to do some research if it is economical and efficient.

Unfortunately to use solar panels that convert sunlight directly into electricity is not economical or energy efficient. The only time it is really worth it is if you are in a remote location and it is one of your only options.

Solar panels lose 40% of the energy from the sun as heat loss. If instead you used solar collectors to directly heat the water you use in your home you would save more money and energy. Solar Collector systems are much cheaper. Why convert the suns energy to electricity only to turn around an convert it to heat again to warm your water?

Photoelectric Solar panels are very expensive to produce money-wise, and energy-wise. With current technology the amount of energy that is used to produce a photoelectric panel is MORE than the amount of energy it will ever produce. The quality of Silicon Crystal required does not occur naturally and the process that it takes to produce it is very energy intensive. ( 2100-2300 degree C temps are required ) Photoelectric power has the perception of being "green" but only if you leave the production process out of the equation.

as for the money side, you might be able to come out ahead if you can buy the panels outright and recieve a tax break. Then if you live in a very sunny area, the more direct sunlight you get the more benefit you recieve.

I am doing a science project,about which is more affective,solar power,wind power,or water power.

Soalr energy has about 15% effeciency in converting the Sun’s energy into power.

1. How is Solar Energy Obtained?
2. And How is it released at power stations?
3. Is Solar Energy Efficient?
4. Is it widely used?

it is obtained by putting active or passive solar collection devices in the sun, they have to be angled to get the best advantage of the light. I dont know how its released, it is efficient where there is a lot of sun, Its not really as widely used as it should be but i think the technology is getting better and the oil prices are getting out of hand, soon there will be wider usage .

probably the assemble of solar cells, battery to thee household items.e.g refrigerator, bulbs, etc…
lets say I have a small house in a jungle and I want to generate electric power for the basic housewares. No need for hot water.

stand in the hot sun long enough, youll sweat, there u go, solar energy

im doing a report on solar power energy so if you would help me by either giving me answers to theses questions or giving me links that will answer them that will be great! Thankz!
-Who are the people or groups of people that came up with the idea of using the sun for energy?
-Do the costs of solar panels make it functional?
-Is solar power energy widely accepted today? Why or Why Not?
-What are the advantages and disadvantages of using solar power energy vs. fossil fuels?
-Were there different designs of solar panels in the past versus today?

THANX

Solar energy was a direct outcome of early observations of semiconductors at Bell Laboratories where they invented the transistor.

Solar energy is economical now, and it is functional. The economy must be viewed as something where the payback is a few years.

Solar energy is widely accepted.

Solar energy does not produce greenhouse gases. It is not controlled by someone else. It will not run out. The energy source is freely available to everybody.

The direction of solar electric panels is toward amorphous (as opposed to crystaline) photoelectric cells. Of course, there are new projects starting that use the thermal energy to heat water and other materials, producing electricity with boilers and generators.
