WHAT IS GREEN TECHNOLOGY?
i need the aims AND objectives of GREEN technology.
also does solar POWER, WIND energy, hydropower etc fall under GREEN technology?
thankyou
WINDMILL FARMS ANSWERS:
Being green today means being more environmentally friendly, for example reducing carbon footprint, pollutant chemicals and energy consumption. If something is made using green technology it means less energy has gone into the production and less pollutants are released by the process. Green technology can also be used to describe things like electric cars, solar panals and wind turbines, these are products that will produce and use a 'cleaner energy'. For example electric is a cleaner fuel source than petrol for cars and instead of producing fumes the waste will be water and co2. However the government makes green materials and technology sound like the answer to the worlds problems when shouting about global warming but infact they bring their own set of very different problems. Charging an electric car will take around 13hours and constant charging will mean you will probably have to invest in a new battery every other year, and considering they cost around lb7000 each, it is definatly not a cheap option. There are pros to green technology but unfortunatly everyone seems to ignore the cons when trying to sell their ideas

A LIST A PROS AND CONS OF WINDMILLS ANYONE?
can anyone tell me the list of PROSANDCONS of windmills?
WINDMILL FARMS ANSWERS:
Pros:
- pollution-free "green" energy source
- wind is a renewable energy source
- do not require much (or any) electrical supply
- no visual, ground or air pollution
cons:
- useless without wind
- do not generate enough power to replace nuclear or petroleum-based power sources
- take up more space and give out less power compared to other energy sources
- high installation cost (you need a transformer and storage cell for atleast every 3 windmills if not less)

SUPRISINGLY NUCLEAR POWER IS THE WAY TO GO?
Apparently the only way to stop global warming IS to completely switch from fossil fuels to nuclear POWER,because nuclear POWER contributes to global warming no where near(AND i mean a only a fraction) as much as burning fossil fuels. Although nuclear POWER shouldn't be used forever, it should just be used as a 'band aid' to mask AND stop the process of global warming until we figure out a new 'greener' effective AND sufficient POWER source.?
AND from what i've heard fossil fuels can not be refined to burn cleaner AND cannot be reused, but nuclear POWER can be reused to some degree if we are willing to make an effort to reuse it. So really while nuclear POWER has been condemmed in so many countries it seems that fossil fuels are doing alot more damage.
at n the s answer. We cant use just environmently friendly ways to make energy because at the moment it just doest wouldnt create enough energy for the world, AND to make room for windmills AND big enough solar panels to supply the entire earth with enough POWER you would need to rip down large amounts of bush AND rainforests just to have enough room to get enough energy,which IS not environmently friendly.

Nuclear Pros and Cons
PROS
1. Fission is the most energy for the least fuel with current technology.
2. Less fuel means less waste, and the waste is all accounted for, not released into the atmosphere to become someone else's problem.
3. Uranium is readily available, very common in the earth's crust (about the same as tin)
4. Economical - operating cost about the same as coal, fuel cost is a much smaller percentage of the total, therefore less susceptible to price fluctuations.
5. Reliable - Nuclear power plants have very high capacity factors, Much higher than solar or wind
6. No combustion, no Co, CO2 or SO2 released.
7. Creates high paying, skilled jobs.
8. Reduce dependence on foreign oil/ fuel. Uranium available domestically and in oceans.
9. High temperature reactors could produce Hydrogen as well as electricity.
10. Fantastic safety record.
11, Does not require back-up and storage facilities like solar and wind.
12. More economical than solar per Mw produced.
13. Much smaller footprint, takes up less land than Solar or wind.
14. May be located almost anywhere on earth, most efficient near a cooling water source.
CONS
1. Irrational fear of all things nuclear.
2. High cost to build and license, large initial investment for long term pay back.
3. Publicly accepted high level storage facility not domestically available.
4. Reprocessing facility not domestically available. (we should build one)
4. High cost of personnel.(high paying jobs in my community)
5. Security concerns, proliferation and terrorism. (minimal risk, easier to refine ore)
Nuclear power, I believe is the best, safest, most reliable, current technology to provide energy. The plants operating now are safe and the new designs are even safer.
Building 100s of new nuclear power plants would improve the economy, reduce or eliminate dependence on foreign oil, create jobs, reduce pollution, and provide for future technological advancement.
I have been working with nuclear power for about 30 years, I would be glad to have a Nuclear power plant or high level waste disposal facility in my backyard. My family and I live in a home within 10 miles of a nuclear power plant. (where I work) I have a great understanding of the risks involved and am completely comfortable with a plant "in my backyard".
I have confidence that my grandchildren's grandchildren will be smart enough to treat the nuclear "waste" as a valuable resource or at least smart enough to handle it safely. If the cavemen thought their children would be too stupid to use fire safely, where would we be now?
Using Chernobyl as a reason not to build is like saying because of the Hindenburg I will never fly in a commercial airliner.
Nuclear power has the smallest environmental impact of any current energy production method per unit of energy produced. One fuel pellet about the size of a pencil eraser produces the same energy as about 1 ton of coal, and if reprocessed 2/3 of what's left can be reclaimed. Nuclear power is our best option for reliable, environmentally friendly, base-load electrical power.
Richard asks...
PROS AND CONS OF CITIES IN CANADA?
I am doing a project for geography. We need to find connections that we have to Canada. I choose these places: Ottawa, Niagara falls, Quebec, Montreal, Edmonton, Halifax. I need to know some PROSANDCONS about these places. If you know some geographical PROSANDCONS about these places (Weather, landforms, features, etc.) If you know any of these PROSANDCONS for any of these places it would help a lot.
AND also Vancouver
WINDMILL FARMS ANSWERS:
For a geography project you may be missing what the teacher is looking for. For Niagara Falls look at the power plants on both sides of the river for example.
The weather. Like those reports in Chicago Cold wind from Canada. The Alberta Clipper. In Canada it is called the Pineapple Express. Starts in the ocean and then crosses the land.
Midwest the RED RIVER starts in Canada goes into the US and then returns to Canada Where do you put the flood control things. Flood Saskatchewan save North Dakota Flood North Dakota save Manitoba. The Great Lakes pollution in one country affects the other. Shipping from the Ocean to the American cites goes through Canada.
If you want to compare cities with similar geography. You need to use city pairs like Vancouver Seattle.. Calgary Denver and so on.
Edmonton the greenest City in Winter in North America. Look it up.
Montreal an Island
Your question is a little confusing when asking about Geographical connections. You may want to look at just an east to west comparison of the two countries. Prairies in the middle mountains on the west side and so on. Are you maybe looking for Economic connections The information you are looking for may be on the city websites.

EDIT your question and you can get a much better answer.
Carol asks...
PROS AND CONS OF AUSTRALIA?
Ok, in the CONS could you mention more like the problems with natural hazards AND also if IS it true that 2/3 australians get skin cancer before the age of 70.. AND if the heat IS extreme in australia..
also consider in the PROS or CONS about the personality AND friendliness of the people compared to the US AND Europe.. etc..
WINDMILL FARMS ANSWERS:
It is absolutely true that Australia has the highest incidence of skin cancer in the world. In fact, one in 2 Australians will develop some form of skin cancer during their lifetime.
About natural disasters:
Australia is not immune to natural disasters despite the fact they don't occur with frequency. Due the vast dimensions of the country, some of this events are secluded to one or another region and don't affect the country as a whole. Some storms are even welcome by surfers and farmers but some others are very dangerous and had caused death in the past.
'The Drought' is without doubt one of the most complicated problem Australia has. Because the vast areas of deserts, and very low annual precipitation, the country is very dry, except by a stripe of green vegetation nearby the coast. Australia in the distant past, had many parts of its territory submerged in the ocean. The result is that the soil is salty bringing many problems for vegetation and agricultural activities. Water is the key factor in Australia and a possible problem for its growth. Desalinization of water is expensive and in case the population doubles today, it will no water for everybody. It is not a surprise to have water restriction in many Australian cities during long periods without rain. Also, due the low humidity of the air, every summer Australia has to face its worst enemy, fire.
'Forests Fires' are among the natural disasters that cause big losses both humans and material. These fires can break out by many reasons, but one of the main causes is the dry air that during summer blows from the deserts to the coast. As temperatures in the deserts get close to 50 degrees Celsius, the wind direction changes, bringing very dry and hot air to the coastal vegetation. This vegetation under a very strong sun and with the help of the hot wind, spark an expontaneous combustion that in one minute can consume a whole block. Cigarettes buts are another factor, as well as agricultural fires that quickly goes out of control. During summer months entire regions may be on total fire ban. That means you can't produce any outdoor fire even to cook.
'Cyclones' in Australia are frequent but fortunately they don't occur to often in very populated areas. Mostly of the areas affected are on the Northern region of Australia and it very rare when they make their way down South. The Northeast and Northwest area of the Gulf of Carpenteria, have very warm sea water temperatures during summer time. All the time these waters rises above 26^0 C. It is like a cyclone to happen, just waiting for the proper wind. Most of the summers in Northern Australia produces easily 28 degrees of sea water temperature. Many cyclones are formed, but not with power enough to cause destruction. The South of Australia, don't receive cyclones, but once in a while it receives very powerful storms from the Indian Ocean.
And now about Australian people:
Australians are mostly europeans as well but I do find Australians are more friendly and welcoming than Americans. I guess culture difference. Americans tend to be more to themselves.
Quality of life wise, certainly the Aussie life is more relax and take it easy style. And the social game is more well played in Australia. I would certainly encourage people to go to Australia and become a dinki-di Aussie.. Like myself..
