What are the risks and benefits of solar energy?
ok first' -The solar energy is good for the environment because it would greatly reduce the use of prime materials like oil(petroleum), coal and all sorts of things. -Technologically speaking the solar energy isn't as powerful as the current source of energy and it would required a lot more of technology to get the solar energy to a more advanced level. -socially i don't see many changes but --Now the huge problem of all this solar energy plan...is that the materials to create the solar panels are way to expensive for average families and they use very rare metals to build them....so if your trying to fix the environment that technology is very welcome... but if u are looking to fix the economy of your country or the world I suggest u don't even mention that idea. I hope i had helped.. P.S. the regular value of making an average family home to a solar powered home its around 50-75 thousand dollars. Good Things Are Expensive =( poor environment
What is solar energy?
Solar Energy is energy that comes from the sun. Solar energy is the radiant light and heat from the sun that has been harnessed by humans since ancient times using a range of ever evolving technologies.Solar energy doesn't produce greenhouse gasses. Solar energy keeps the ocean from freezing and pushes the currents. Solar energy is necessary for plants to photosynthesize. Photosynthesis is when a plant makes food for itself using the sunlight its leaves collect. Without the energy of the sun we would be on a very cold planet. There would be no living things on Earth.Solar energy is the most powerful and abundant source of energy we have available to us today. For that matter, it will always be a limitless source of energy. The great thing is that solar energy is renewable. It doesn't matter how much we use, the same amount of energy is always available.Harnessing solar energy is the key. We can use its heat or convert its light to electricity. We now have technology to tap into solar energy in converting it to electrical energy. This is accomplished through solar panels which contain solar cells. The electrical energy is produced as direct current (DC). Often times, this is converted to Alternating Current (AC) voltage for home consumption. There is another type of solar panel through which water is circulated so the water is heated for domestic use.There are also large scale uses. A good example from the California Mojave Desert can explain one method of how solar energy can be used in creating electricity. In the solar power plant, curved mirrors are used with running pipelines at their foci. The mirror focuses on the pipeline so that the heat it receives heats the pipe as well. This pipe gets so hot that the oil it contains can heat water and turn it into steam and the steam can be used in moving a turbine to create electricity. The solar power plants use a lot of mirrors above the pipelines to get heat and then create electricity.Electrikals..
What are your views on solar energy?
Solar energy is on the face of it a very good way to get energy from a renewable source. However there is a down side, this is in the requirement for batteries to store this energy for later use, these batteries are not that efficient, nor are they that "green" to make. To power small things, e.g mobile phones etc requires only a small solar panel, however if you wanted to run your home completely on solar energy you would require a large solar panel array and a lot of batteries, and inverter etc all this is at the moment quite expensive to set up. Solar energy to heat water is a good solution, even if the weather is only warm enough to partially heat it it will reduce costs and the amount of other energy needed, hot water solar systems are easily fitted to most homes. The total amount of power/heating you get from your solar system will of course depend on the amount of sunshine available, works well in areas where the sunshines, but in extreme northern and southern regions of course this is limited to the shorter winter days. Saying all that solar energy is a good thing and one that hopefully will be developed future, already solar "power stations" are in use providing clean power, these look st to be expanded and technology will improve their efficiency.

What are all of the benifits and risks of using solar energy?
There are many pro's and con's but the average green warrior moron will simply say GO Green...with out actually considering what they are saying. For instance, were you to have a solar system, chances are, its going into an already existing home, meaning it will be a retro fit. That means either re-wiring your house for low voltage appliances and devices, OR you have to get a converter, since solar cells give DC voltage, you will need a DC to AC converter. You will also need a battery bank, since you obviously will want power once the sun goes down, which means you will also need a regulator since there are specifications on all the regular appliances in the house. That's also assuming you have a southern exposure to the sun uninterrupted by tree's or structurs to place the solar cells. These solar panels also cost a pretty penny, meaning if you go for an "off the grid" kind of living, you will have a big bill in the neighborhood of $25,000 Plus or Minus depending on your electricity use, routines, and how large the home is. But now the problems. Most whole house systems don't actually pay for themselves. So you will end up with financing a large project, but then have no problem living off the grid.....UNTIL..... Say a solar panel starts dropping in efficiency....maybe its due to wear, maybe its just the panel needs to be cleaned. Then there's always the chance that some of your batteries will not hold a charge well. Maybe the regulator burns up or the DC to AC converter blows. And i'm pretty sure there's no overnight store, opened 24/7 with panels and parts to make instant repairs. Assuming you did the repairs yourself. Otherwise, you'll have to call up a repair person and set a schedule. Can you do without electricity in the house until then ? If your lucky, the repair will be under warrantee. I have heard recently of Solar City whom claim they will install a system and charge you about what you pay for electricity each month without any down, but I haven't looked into it, and for me, Since I pay only about $45 a month for electricity, it doesn't pay for me to get a full system.

What are the risks of solar satellites beaming energy to Earth? How beneficial can they be? Is there a programme going on to prepare to deploy them?
Without offering numbers since we have been notoriously poor at providing accurate budgetary numbers for large space based projects, let's take a qualitative approach. Independent of the technologies chosen at each step, solar satellites insert several very ($) costly process steps each with its own additional (energy) loss mechanism in the chain from the sun to your wall outlet. We can already do this here on earth for a lot less money with higher maintainability and continually improving conversion efficiency. The problem of variable insolation angle and night time off hours in ground based solar is not solved by a space based system which must still maintain line of sight with its ground station. If you want more ground stations and envision a ground station hopping scheme you still have to straddle the oceans. The incident beam angle changes and presents the same problems as solar unless you invoke beam shaping and ground receiver technology immune to the angle change. Unless they have considerably higher power density (solar is a little under 1kW/m^2 depending on latitude, season, etc.) they have no advantage over solar in land area required at the earth surface receiving station. If they have a high power density multiple, they make the base station zones and some safety buffer around them uninhabitable. Solar can occupy roofs everywhere at no opportunity cost in loss of other uses. Depending on scale, spaced based solar may make power distribution more costly by reducing the number of ground stations and increasing their spacing. In short, space is easy to fall in love with for the tech geek (I'm guilty) but a close look reveals many actual disadvantages. The business proposition just isn't there and it won't be long after ground based solar becomes viable on a larger scale. And buy the way, the largest, highest payback near term use of solar is water and space heating which seems to go by without notice in most discussion of solar that comes up. Space based solar has nothing to contribute to this. In a ($) resource limited environment, all energy sources trade against each other and space based would take away from others with more immediate value.
Why is solar energy good?
The whole world is looking for cleaner ways to produce energy and replace the 'traditional' way of producing energy.There is one more way of getting energy i.e. Nuclear energy but it is not ready yet for common usage. Also, the nuclear energy is not that much popular among common people.Human's main problem or better to say the need is - we need energy to survive and it is required at a large extent. We need energy consistently.So how it is possible to get energy consistently? The best option to look for is all of the renewable sources we know.But why we should consider solar energy over other renewable energy sources?It is because solar energy has more advantages and lesser flaws if compared to other renewable sources of energy. Also, solar energy is a popular and a big topic among other renewable resources of energy.Wind Energy - require lots of space.Hydro power - requires much larger space like dams etc.Solar Power - It can be produced anywhere in the world where the sun shines. It doesn't take up that much space for installation as it can be easily installed even in a small building.The energy efficiency conversion rate is reasonably high in solar energy. Solar energy can used for various applications.And one of the most important thing about solar energy is - it is really cheap and easily accessible.If you want to take advantage of solar energy and looking to install solar panels at your home or at your commercial area, consider the services of the company - Department of Green Energy Inc. situated in Fort Lauderdale, Florida.More info on solar energy can be found at our website - Solar & Renewable Energy | Solar Panels | Department of Green Energy
What are the social impacts of solar energy?
The social impacts of solar energy have a lot of pros and cons. Unfortunately, it is being sourced as a wasted resource, and to have it replace a system we have right now, is not beneficial for countries to do in the short term as they (Companies and Governments) have a lot to lose. It is however, beneficial for individuals to gain perspective on its long term outcome and do something to release its true potential, without stepping on too many toes. It is a costly idea governments have not taken on without peer pressure from groups, naturalists and architects who are trying to build into the sustainable future we are trying ever so hard to look after, and with global warming having a serious affect on our planet, hopefully all will be achieved in time.....
What are the benefits of wind energy, what are the risks?
Advantages: 1)Wind energy is friendly to the surrounding environment, as no fossil fuels are burnt to generate electricity from wind energy. 2)Wind turbines take up less space than the average power station. Windmills only have to occupy a few square meters for the base, this allows the land around the turbine to be used for many purposes, for example agriculture. 3)Newer technologies are making the extraction of wind energy much more efficient. The wind is free, and we are able to cash in on this free source of energy. 4)Wind turbines are a great resource to generate energy in remote locations, such as mountain communities and remote countryside. Wind turbines can be a range of different sizes in order to support varying population levels. 5)Another advantage of wind energy is that when combined with solar electricity, this energy source is great for developed and developing countries to provide a steady, reliable supply of electricity. Disadvantages: 1)The main disadvantage regarding wind power is down to the winds unreliability factor. In many areas, the winds strength is too low to support a wind turbine or wind farm, and this is where the use of solar power or geothermal power could be great alternatives. 2)Wind turbines generally produce allot less electricity than the average fossil fuelled power station, requiring multiple wind turbines to be built in order to make an impact. 3)Wind turbine construction can be very expensive and costly to surrounding wildlife during the build process. 4)The noise pollution from commercial wind turbines is sometimes similar to a small jet engine. This is fine if you live miles away, where you will hardly notice the noise, but what if you live within a few hundred meters of a turbine? This is a major disadvantage. 5)Protests and/or petitions usually confront any proposed wind farm development. People feel the countryside should be left in tact for everyone to enjoy it's beauty.
