Benefits of Solar Energy

Archive for the ‘Benefits of Solar Energy’ Category

im doing a senior project i’ve done the paper and now i need to do a show that im going to judged on by my teachers and the community. My topic that im doing is the benefits and drawbacks of solar and wind powered energy. i need an thought on how to show my topic. if you have an thought please help me!!!!!

Found the following YouTube lecture from Arosa Solar Energy Demonstration Lakewood Cheder at http://www.youtube.com/watch?v=ut0988zeA-M you might take some thoughts what to say and what not to say.

I see some FAQs in regards of Solar energy at http://www.arosaenergy.com/faq.html that might help you with your lecture.

Note: Your teacher will grade your

1. The answer the teacher is looking for is probably (B) 4.2 m/s because that is the closest to the square root of 18, which is an exact value.
2. D. I reckon all of them involve potential energy because if a "release" happens to those objects, there will be movement.
3. C
4. my guess is D; it seems like you would multiply all those numbers.
5.D
6.B (I mean the point of nuclear POWER is the power of electricity)
7.D
8. C
9. I don’t know what figure 15.1 looks like
10. C
11. B
12. B
13. C (water), I reckon; it seems to me that the byproduct would include hydrogen in it.
14. C (C says both a and b; both a and b seem to be able to be seen as excellent thoughts)

Like in India and parts of Africa, and especially the use of solar power.

poor places can benefit from renewable energy by producing energy on site as opposed to running hundreds of miles of cable to get things like electricity out to them

its for a science project, and i have to give the environmental, technological, social, and scientific risks and benefits, please answer as soon as possible

Solar exists in two forms, photovoltiac and heat related. The problems with photovoltiac are cost of materials, fragile cells, cells "wear out" and need replacement after about 10 years. Of course, power is only made during the day. With heat plants, the sunlight is reflected with a mirror array to a central tower where a heat exchanger is located. The piping contains a salt which is liquid when hot enough. Heat is stored in the liquid salt in insulated tanks underground. The hot salt is used as the heat source to boil water to turn a turbine generator. Heat stored in the tanks can be used after sunset much like a car battery stores electricity when the car is not being driven. The disadvantage is the salt is highly corrosive and hard to handle. And, if allowed to cool, becomes a solid. The only terrible thing for the environment with the photovoltiac array is the amount of land covered by the array and the exotic chemical processes used for manufacture of the cells. For the heat plant, the terrible thing is the salt used, which is corrosive and hard to handle because it is SO hot. After all, salt is a form of rock, and liquid rock salt is a close relative to volcanic lava. Otherwise, the heat plant has the same thermal footprint as any other heat power plant such as coal, gas or nuclear. All steam cycle plants exhibit the same thermal effects, using heat to boil water, and needing cooling from water nearby to condense the steam back into water so it can be fed back into the boiler, which heats the environment where the cooling water comes from. Unlike oil, coal and gas fired power plants which rely on combustion, there are no stack gases from the solar heated power plant. Both types of solar power plant are considered to be GREEN because thermal footprints are not a majority contributor to hurt to the environment, as the problems are very local in nature. The major problem why solar is not more widely used is simple economics, the cost of installation is huge compared to other types of power plants. Both types require huge areas of land to collect enough light to make them practical as a utility serving many customers. The solar photovoltiac array on a roof powers only one house, reckon how much area you need to power 10,000 houses. Houses can also use the sun to heat water and use the heated water in insulated tanks to heat the house on cloudy days. Solar water heating just takes a really huge tank per house. Water is cheap and the technology exists to make durable system which will last nearly forever. Except for cost again, single house solar heating is practical. A friend back in the years before Y2K, went off the grid. He firmly believed Y2K would be a total meltdown of society, so he had a house built way far away from Seattle in the Olympic Mountians on the coast of Washington. He spent roughly $40,000 on the solar heating and electricity and pays no utility bills except for water. He has a well, but it is metered by the county where he lives. The problem he has is age. The systems are now over 10 years ancient and he needs a total replacement of the storage batteries and solar cells, to the tune of about $10,000. With the initial cost plus the replacement cost, he has spent $50,000 for 10 years of services, which works out to about $400/month. If he lasts another 10 year and spends another $10,000, his monthly cost will be about $250 per month. The problem is this: his ancient utility bills rarely ran over at most $200/month in winter and as low as $70 in summer, averaging about $120/month per year. As you can see, the systems he has have not paid for themselves and even after over 20 years, will STILL be costing him more than if he had used the community utility systems to power his lifestyle. The real problem is initial installation and then periodic maintenance and replacement costs. Maybe after 30 years, the systems will equal out and "break even". A utility company is NOT going to invest in such a terrible deal to generate power. Utilities need a return on investment much sooner than 30 years. I want to go solar. I really like the thought of not relying on a power company for lights and heat. It IS the most environmentally friendly source of energy to power things for us… I just can’t afford to do it…

I’m writing an essay of the costs/benefits of solar energy, if you have any suggestions for the costs of using solar energy that would be fantastic! Thanks for your help

of course.

But the benefits do outweigh the manufacturing process in terms of BTU’s used.

Since we are born, we are thrust into a world of material and money, naturally we evolve to know this shifting concept and overall it plays a major role in daily lives.

With "money" being a man-made object. Why? When all of Earths natural resources are FREE, and we have enough human intellect to take us to a new level of social interaction, do we feel that MONEY & VALUE must be imposed to improve our lives?

Place it this way. We have Solar power within our grasp. It is possible, in this day and age, that someone, somewhere, is going to make it compulsory that we pay to use Solar Energy.

Ultimately, this resource is free (as is everything else on this planet), would you find it acceptable that we pay to use this resource? Or Nuclear? Geo-Thermal?

Do you charge yourself a nominal fee, when you grow you own crops to eat?

You know where I am coming from? What is the ultimate purpose of money when everything around us naturally free?

I could give you an answer on this thats pages long. but instead, I will just give you the answer.

Money does not benefit the human species

i am writing a research essay and need some sort of article about benefits and costs of solar energy. Or the history of solar energy etc. thanks

bunch of solar energy articles, including benefits, cost, disadvantages, etc.. have fun:)

I am writing a research essay about the cost/benefits of solar energy. Any Thoughts how i can arrange this? what to include? thanks

Maybe you could run with the fact that our entire planet runs on solar energy already – it provides us heat and light, grows our crops with photosynthesis, causes evaporation, clouds and rain and is therefore also responsible for giving us water. It even gave us oil, coal and gas because the dinosaurs wouldn’t have been here and the ancient trees wouldn’t have grown if the sun wasn’t bright! So there’s a few benefits. Now for the costs ….

The major benefit of solar energy is its low:

1. cost
2. pollution
3. maintenance
4. complexity

pollution
