Does Solar Power Pay Off?

We all know heat produces such a quantity of energy that there is no stopping the potential. There are two types of solar technology, the passive and the active solar energy. The difference between the two is simply in how the heat is harnessed. Active Solar engineering uses (photovoltaic) panels, combined with solar thermal collectors, and then channeled through mechanical or electrical equipment to make Solar Power electricity. Skylights are the best example of the use of Passive Solar Power.

How do we get electricity from the sun? We all know what a "solar panel" is; solar panels take the the energy from the sun and convert it into an actual electrical current using the process of what we call the "photoelectric effect." Intensified Solar Power produces an overwhelming amount of energy.

In this process, the sun is focused with several mirrors and lenses in order to focus and concentrate the energy of the beam. There are many technical advances that focus solar energy in such an intense quantity of power such as: the solar power tower, the solar trough, and the parabolic dish.

Is the conversion to solar economical? The main concern of the value of the solar power energy as a sustainable power is that no sun throughout the night. Modern times require a continuous supply of light, heat, power. We are so "plugged in" in today's society. One might suggest that solar power storage is feeble and not able to keep up with our needs. That is why storing of solar energy is a key so essential. Thermal storage systems can save solar energy, but can they save enough? Newer scientific discoveries additionally made the way for thermal mass storage systems which vary storage capacity and function by storing supplementary energy during off peak times and varying supply at peak consumption hours.

The rising expense of electricity, the unpredictable oil prices, and its degenerating source, have raised the demand of solar power for certain. The environmental wellbeing has impelled companies to create more affordable solar ability and sell it commercially. It's true that solar technology is rather expensive right now. Many trends, however are showing that it is in our future by default. Even in the Real Estate market, builders, contractors, and even home owners have incentive to "go green." I don't see why this trend should dissipate as we are only getting better with the technology anyhow. I believe that in the next few years, the demand for solar technology will be far greater and the cost for it's conversion will go down.

Nuclear against Solar?
Im arguing with my friend. Im with Nuclear Power my friend is with Solar. Here is what the argument is like so far Me - Solar power isn't very efficient, especially in the Britain! It rains a lot. Harry S. - it's cheap and efficient and works on light not direct sunshine. Me - Nuclear power is more efficient, although it leaves traces of radioactivity. Harry S. - Solar panels are very small and there's more of them in the UK. Me - Solar power IS nuclear power. Just because it's very very far away doesn't make it less dangerous. Solar power is NOT free. There's the opportunity cost of not being able to harvest food / bio fuel crops where the panels are placed. Solar panels are also less efficient than plants at capturing all the radiation energy. Burning wood would be more economical for the ecosystem. Too many solar panels affect the landscape in a negative way. Nuclear fuel / waste is compact. Few centrals are needed. Some reactor types also produce useful byproducts (plutonium). Nuclear power can be generated anywhere, not only in sunny regions. Harry S. - Nuclear power stations are extremely expensive to build and can be dangerous exposing us and our world to harm full radiation e.g Chernobyl and Japan. These disasters have polluted farmland and killed hundreds of people with millions suffering from long term health problems. Who has been killed by a solar panel? The price to life is to high for nuclear! Solar panels also look better than a huge concrete towers. Me - The forgotten dangers of solar panels: According to Safework Australia, each year about 30 Australians die in falls from a height. Some falls involving people installing or maintaining solar panels are not reported as part of work-related statistics, and then there are people electrocuted when they come into contact with power lines. In California, where solar panels have been embraced enthusiastically, there has been a rash of deaths like this one, this one, and another three in quick succession. However, it is a worldwide phenomenon, so much so that statistics show roofing is more dangerous than coal mining. Because of our propensity to put panels on roofs, solar is in fact, far more dangerous than many forms of power generation, three times more dangerous than wind power and more than 10 times more dangerous than nuclear power, by comparison to the amount of power produced. The fifty actual deaths from roof installation accidents for 1.5 million roof installations is equal to the actual deaths experienced so far from Chernobyl. If all 80 million residential roofs in the USA had solar power installed then one would expect 9 times the annual roofing deaths of 300 people or 2700 people (roofers to die). This would generate about 240 TWH of power each year. (30% of the power generated from nuclear power in the USA). 90 people per year over an optimistic life of 30 years for the panels not including maintenance or any electrical shock incidents. There is an argument, however, that solar power may ultimately be safer than coal-fired generation because of the reduction in pollution. Ironically enough, however, solar power is far more dangerous than nuclear, even in a year when an accident like the disaster at Fukushima occurs. What do you think he will say next? Does anyone have anything to say about nuclear power that will support me? Do you think nuclear power is better. Why? Is a nuclear power plant cheaper than the overall cost and maintenance of a solar farm or a solar panel? What are your views on nuclear power and solar power? Any pros and cons about nuclear and solar? Could the world still run for a bit with nuclear power? If you lived that long how did you react when nuclear power was introduced. Did you think solar was better? If you have anything that could hep me win this argument please say.
