What you people think. When u concentrate the Solar energy it will rise the temperature of the surrounding much more and faster giving rise to added global warming. what is your opinion about it pl feel concern and think carefully and logically ?

You have brought up a good point, actually.



If you are talking about photovoltaic solar power, yes the many large batteries that are usually used to store the electricity to feed to the inverters represent a lot of pollution, especially in their manufacture, as does the manufacture of the panels themselves. Both components have a limited lifespan, and unless totally recycled will cause yet more pollution.



However, having said that, if the solar power is put into use for a long period, then its benefit would outweigh the degree of pollution in comparison to conventional fossil fuel power conversion. This especially true if the solar power is directly converted to AC and fed directly to the grid during daylight hours.



This equally applies to wind power (another kind of pollution - visual) unless the turbines are synched and can feed direct to the grid, without the use of storage batteries and inverters..



In the case of mirrors feeding heat to boilers and steam turbines, the pollution of course is the steam, the water vapor byproduct which, as we all know by now, constitutes 95% of the gases which cause the greenhouse effect (love it or hate it). This is a serious downside to this technology.



Until the technology is perfected to convert heat directly to electricity efficiently, the problem continues. Just like coal/oil powered and nuclear powered stations we seem to be stuck with steam pollution. The only way of mitigating it might be to feed it out to sea and expel it deep underwater, not really possible unless coastally located..

One piece of technology: Hydro-energy storage.



Pump water up to an artificial lake at the top of a mountain to store energy, and then let the water run down through turbines to retrieve the energy later, eliminating most or all of the need for batteries.



Usually this stuff saying renewables suck is BS when you actually try.



Yet another method, are solar power towers which last longer than solar panels and continue to generate energy at night. While a non-universal storage method, it's good for storing the sun's energy in the mechanism that generates the power. According to some studies, they are the best option next to wind turbines. I'll describe a particular model. A field of mirrors beams light to a part of the tower which contains salt, for it's incredible heat storage capacity when molten. In turn, the heat from that region heats water which spins some turbines, generating lots of energy. Currently, the best models continue to generate electricity at night and for a few consecutive cloudy days.



I think whoever was saying that was probably trying to delay response. There are too many ways around that to be true, and saying that it contributes more to Global Warming than fossil fuels is a lie.



This is why some government intervention is needed: The companies aren't responding to "new" ideas, and they happen to often be fossil fuel companies as well. If you don't create the environment where it lowers fossil fuel consumption, then they win because prices stay high.

The only form of Solar power generation that would warm the Planet is Orbiting power stations which then beam the power to Earth as Microwaves. That would mean sunlight that would have missed the Earth gets directed down to the planet instead.

You are correct that manufacture of Photovoltaic Cells and Batteries are a dirty industry, and don't get me started on "long-life" light bulbs!

Well, it is true in a way that solar power COULD add to problems by causing more battery waste (for those devices that use rechargeable batteries). And while I love solar power, I certainly don't think it is economical or wise to use in every circumstance.



Some items, however, are brilliant. Such as solar powered water heaters, solar heaters, etc. These items don't actually use silicon panels, but instead simply divert heat to coils or water to provide the hot water (or air).



So yes, some could add to the problem, and others are helping.

There are several places where you can use the solar power directly without storing it. I am having 3 fans run by solar energy. Mostly for office time use according the out side temperature the fan speed also increases and it is very comfortable for me. Even our Government run science center has asked me to supply one for their non conventional energy park. By using the solar cell power directly we are able to run at higher efficiency. Mostly in India the banks and other establishments where computer operation is a must they connect the main through rechargeable battery.In this case it obviously harm the atmosphere.

No. The concentration is not a big deal, since the solar radiation was headed for the Earth anyway.



And by converting some of it into more useful forms to make electricity, heat water, heat buildings, etc., there is a SUBSTANTIAL reduction in global warming, compared to other methods of creating power for those.

If youre talking about the pollution created by the manufacturing of batteries and photvoltaic cells and panels, it is true they are not very green during manufacturing. But then neither are dirty forms of energy. Oil wells have to be built, the metals used have to be mined, transported, welded, and they use lots of energy to run. Then the oil is transported around the world and burned. Same with coal, it has to be mined by big trucks and transported usually by train before being burned.



When everything is taken into account, solar is the cleanest energy available given the time it takes to displace the pollution used to create the cells and panels.

when u generate solar power, u dont generate extra heat. you simply convert sunlight/heat into electricity (and some of it is again released back into the surroundings). so no, it will not aggravate global warming.



solar power has great potential. we get more of it in an hour than the entire world consumes in a year :)

I don't think you know the meaning of careful and logical thinking. You seem to believe that solar power somehow brings more solar energy to the earth.



I'm assuming you're talking about solar thermal power, which concentrates the sun on a tiny area. But this works by reflecting it from the surrounding area with mirrors, meaning those areas get cooler than normal, which completely offsets the increased solar warming in the concentrated area.

If you are talking about a solar furnace there is no added energy it is focused onto a small area to generate great heat, this is energy that would have heated the ground over a large area (now covered by mirrors)

As Dawei stated unless Solar input changes the energy input is the same, unless you are planning on re-writing the Laws of thermodynamics and that would require a lot of careful and logical thinking.

By the thumb down he has received it looks like at least one person here, doesn't understand these laws.

No,it is otherwise actually. Global warming is a result of burning excess of mineral fuels like petroleum,coal etc.By utilising solar energy in place of mineral fuels emission of harmful gases like CO 2 etc. will be reduced. Solar energy will also reduce our dependence on mineral fuels. Solar energy should be used to replace burning of fossil fuels.

Global Warming is a lie. The real worry is political corruption and our slide into tyranny.



Don't worry about the planet. Worry about your country, and what your politicians are doing to it. We are losing our freedoms!

No, sun energy hits the earth ANYWAY, either you use it or you don't. Solar is probably the best type of energy, just look at how plants use the sun to make energy. And if anything plants HELP the environment for us.
