Sweden goes for green as Nordic mull energy future

Sweden has been aware of the meltdown of fossil fuels for years now and are working on a green policy plan to reduce the use of fossil fuels and nuclear power. European union is calling for a coordinated policy with the rising demand, uncertain supply and the need to cut greenhouse gas emissions. The Nordic region expresses a concern for there environment and the climate caused by pollution. After the Ukrainian town of Chernobyl exploded with radio active chemicals they new some measure needed to be taken to stop atomic energy , so in 1980 Sweden had voted to get rid of it. I not for sure it how it went obviously unsuccessful since they are still fighting for this law. Sweden goal now is to break from fossil fuels by 2020 and to reduce green house emission to help stop Global warming. "We have to transform into a non-oil economy," said Stefan Edman, who heads the Swedish government's oil dependency panel. "We have very high ambitions, although I don't think it is realistic that not a drop of oil will be used in 2020." Sweden have already manage to cut oil usage in homes by 70%. Professor Christian Azar talks about the biggest challenge will be to reduce the use of oil by transportation. Azar also says that if they can get it down to 50% dependency how that would be a humongous accomplishment. Europe has got a big head start on many contraries and looking to take full advantage of it to become role model for other countries like us. Right now Sweden gets 35% of its energy from oil but with nuclear power arising there is a demand for an alternative energy source. For other countries like Finland nuclear power is a part of there future but smarter countries like Denmark and Norway are looking for alternatives to reduce pollution and global warming.

==Bonus Essay Number 2==

The article "Rising gas prices hit cities, school districts" explores the effect that high gas prices has on cities and schools.

Because gas is almost at three dollars a gallon, it makes keeping police patrol cars and school buses fueled up rather hard. Some of the cities and school districts mentioned in this article do not have enough money budgeted for this fiscal year for gasoline. So on one side, there is not enough money, but on the other hand, they are forced to keep running school buses, for example. Without school buses, half of the kids in the school district would not be able to come to school each day. And patrol cars are very important to keep our roads and neighborhoods safe. You would not want to call the police about something and have them say, "We're sorry, we can't make it to your house because our police cars are out of gas" So what are they to do?

Well one option is to convert the buses and police cars over to ones that can use alternative fuels such as electricity and natural gas. Some of the cities mentioned have already started doing this, and are quoted as saying that it helped cut down their fuel costs tremendously. Also, vehicles that use alternative fuels are a lot cleaner and don't pollute the environment.

So some cities are going to exceed their budgets, and some are applying for grants to help them switch over to alternative vehicles. And I bet that all of them are praying for gas prices to go down.

The article "Alternative Energy: Harnessing sun could help power Michigan" talks about the potential that using solar energy has.

Solar power is probably the most readily available method of alternative energy that there is today. Solar power is obtained by capturing light from the sun in solar panels, and can be used to heat water, and generate electricity. Those two things can save you a lot of money, especially in the long run.

This article talks about the progress that the state of Michigan is making in the world of solar power. Michigan's Energy Office is promoting solar energy, and providing PV demonstrations. Several energy companies are building solar plants, and expanding their solar panel business, which along with helping the environment is at the same time providing more jobs.

There are those who criticize the development of solar power in Michigan, however. Some people say that it would never work because the amount of sunlight that Michigan gets is not very much, and others say that solar power is too expensive compared to natural gas and coal.

I think that using solar power is a great idea, and Michigan should continue to develop it. It is the cleanest of the alternative fuels, and almost always in ready supply. Mainly, we just need to stop our dependency on oil and natural gas, because of the high prices, short and unstable supply, and the bad effect of it on the environment. In my opinion, any source of alternative energy should be seriously considered for use in the United States.

==Bonus Essay Number 4==

The article "Alternative energy pushed by senator: Perata unveils host of 'green' policy bills" delves into the legislation that the state of California hopes to put into practice.

Senator Perata announced a bill that promotes oil conservation, solar energy, hydrogen fuel and greenhouse gas standards. With the high prices of crude oil/gasoline, global warming and other detriments to our environment, we need to put these alternative fuel methods into practice as soon as possible, and I think it's a great idea to propose a bill to promote alternative energy sources as the primary ones.

This bill wants to expand the use of renewable resources, which are better for the environment, as well as less expensive, and we have control over them, unlike the gasoline prices.

Hopefully, other states will take notice of California's bill, and soon more bills like this will be proposed. The United States really just needs to unite and promote alternative energy, to make our country cleaner, and non-dependent upon foreign imports.

Rising Gas Prices Hit Cities

AThe article mentions how the prices effect cities and schools. I hadn't thought about the schools hving to pay for buses and patrol cars. The city of Arlington put aside $2 million for gas this year. They may have enough if gas prices don't go up. Many cities are beginning to use alternative fuel vehicles. THey are using electricity and compressed natural gas. We, as consumers, complain that we have to cut back on driving, but we don't think about the cities and schools that can't just cut back on driving. Public agencies like that police departments can't just park their cars. And buses can't stop picking u the children fro schol. People are beginning to double gas spending and these peoiple include the pubic departments. Schools and cities are getitng hit extremely hard by the increase in gas prices

the article discusses some of the different ranges of spending amounts for different schools and cities and the amount of increase which is around double for everyone. and then those schools that are getting grants for some transportation may get less this year because of the rise.

they are trying to find ways to cut down on fuel spending.a few cities have their own CNG stations for refueling. which for one city only totals about 50 dollars a month for 4 natural gas vehicles. and they are working on buying more of those vehicles next year. many employees in many areas are being encouraged to carpool everywhere and aviod idling their vehicles. a schol district is hoping to buy compressed natural gas-powered buses. they have reiceved $300,000 in grant to do so. but each bus costs $130,000 and the station to buy costs another $400,000.

But his heart-felt comments that he will do his darndest to help us little guys against those big, mean, corporations that make a billion when they sneeze out policy to gouge us fall short of an effort.

==Alternative Energy Pushed by Senator==

This article talks about how Senate President Pro Tem Don Perata wants Californians primary source of energy to be alternative fuels. Because of the outragous gas prices he feel this is neccessary. A bill has been proposed that will find a more effecient use of traditional energy sources, and allow companies to experiment with alternative fuels and possible obtain more financing. It is believed that the governor of California will agree with the bill, but might suffer some pressure from opposing parties. The use of alternative fuels will result in a positive for the consumer, less money spent, the producer, profit off of inventions, and the environment, less fossil fuel usage. I think that if the bill is passed in California the influence of it will spread to surrounding states and ultimatly most of the US will begin to value alternative fuels more then what we do today. I think this is a good idea and hopefully it doesn't take long to catch on.

Essay on "Alternative Energy: Harnessing sun could help power Michigan"

I think the use of solar energy has many benefits, three of those being lower costs, better energy efficency, and better conservation of energy. Solar pollutes far less than coal and other fuel sources and loses less energy while producing electricity. The supply of the fuels we are using now are becoming depleted so fast that solar's popularity will increase dramatically in the next few years.

Coal and other fossil fuels cost so much to use and use so little of the potential energy it is a wonder that we are even using them. Solar power can be found almost everywhere on the planet, and is totally renewable.Plus with the cost of solar panels decreasing, changing over to solar will only be a matter of time.

When we convert to solar, we won't need to depend on other countries and their supply of oil, natural gas, and coal. Our economy will improve as more jobs are avialable and we don't have to spend so much money to get rid of the by-products of creating energy. No more 100% chance of smog today in L.A., no more acid rain, crop loss, and 3 bucks a gallon for gasoline.

We already use solar out West and to heat our pools and greenhouses, why not take it to the next level? All that is stoping us is the coporations that want us to depend on oil, and our willingness to see how much we could improve our situation.

I hope to see in my future more use of this very helpfull, but overlooked source of energy that is just sitting there not being used. We will have to wise up or become slaves to the Middle East till the oil runs dry.

==Motoring body backs alternative fuels==

This article discusses the cost of gasoline and its effect on Australia. Many are suggesting that Australia look into alternative fuels, as the gas prices continue to rise. Gas is now $72 a barrell in the United States, this has resulted in Australia prices to jump to $1.40 a liter. Many Australians are upset at this jump in price but the article argues that if they keep the prices low and take a loss and gas prices never drop then they will go bankrupt. The article also points out that gas prices reflect world availability and while they might drop a little bit ultimatly they will rise at a steady rate, so Australia, as well as other countries need to really look into alternative fuels.

* Just a funny story, my aunt went to Canada with her family and they noticed that gas was extremely cheep so they brought the two cars that they had driven to a gas station and filled up, the whole time they were talking about how cheap it was. They did not realize it was priced by the liter rather then the gallon.

Not only is solar energy good for the planet it is also good for our bank accounts. Solar energy is light from the sun which is captured by solar panels to heat different systems. They can be used to heat water and also be colleceted to use as other energy sources. There are even some panels that are clear so you can hardly see them. Manufacturing plants also mean more jobs for people.
The states that are able to have these should back them. The investment would help everyone in the state. Not only will it help with cutting down on pollution but it will help cut down the prices. Coal and gas are hurting us and the planet we should force these to become our back ups and not solar energy.
Michigan has said that they are able to do this and there are enough sunlight days and hours to make this happen. They have even proven this by using solar power for part of their school. This is a great idea. It helps get the future generations involved and proves to those who do not beleive that it is possible. Solar energy is such a clean sourve we don't have to worry about what it does to us or the environment. There are already twenty-one states with renewable portfolio standards why can't we do this for all of them?

a) Click on the article, "Hurricanes vs. Homes: Should Building on U.S. Coasts Be Stopped?" Discuss the article's point of view, and how it pertains to population, environment, and ethics. (10 points) {{OK}}

The article states the point of view of two Florida representatives, one wants to keep the process of building and selling because of revenue and one wants to stop the building all together. This of course leads to funding problems because the government can not pay for all the land that is in danger zones. But he would consider more strict building codes as an alternative. The population is involved because the hurricane directly effects them and their economy. The environment would be better off if the building stopped because natural habitats could be restored, but on the other hand it would take away from the economy in the form of lost labor, tourist revenue, etc. Ethics is in reality different for political parties. Of course one wants to keep the areas they way they are now and the other wants the areas to be shut down all together. It depends on your political stand point and morals and ethics. I think it should not grow anymore and the current building codes should be more stringent.

b) Click on the article, "China Makes Stable Energy Supplies Top Priority for Economic Planning" Discuss the article's point of view, and how it pertains to population, environment, and ethics. (10 points) {{OK}}

The article says China needs help and we and other countries should do so. Two thirds of China's energry is produced by coal burning. This has created a global warming issue. China does not have the revenue to put towards oil technologies and the mere fact of discovering oil. The article states that the government pretty much runs the energy that supplies China and all other countries should invest in making China more efficient. The population would benefit a lot from the outside help. The environment would become more clean do to better technologies. The ethics on it vary from country to country, but I would say most countries would be for it. Its good do have a big allie, but than again do we want this big country to have better technologies and resources because of the possibility of a future threat? I don't know it depends on your political and ethical back ground. I myself would say it would be fine to allow them certain technologies that would help promote a cleaner environment.

3. This topic goes pretty deep, but I know that we get most of our oil from the middle east, and since we are at war with them right now everything is going to be more difficult. But at the same time prices weren't even this high in 2002, right when the war began. I don't know the person that sets the price for a barrel of crude oil and who the person is that says gas has to be $3/gallon, but someone is making alot of money on it. It doesn't seem fair to people of the middle class to be stripped of their money so someone can get rich.

==A Common Disadvantage of switching to clean fuels for vehicles=={{OK}}

A common disadvantage of switching to any of the clean fuels seems to be either higher fuel costs, or higher vehicle costs. Because some of the fuels deemed to be clean might be in low or limited supply, they could cost more. The adaptions that a vehicle needs to be able to run on clean fuel could also be costly.

==An overwhelming advantage of switching to clean fuels=={{OK}}

The most overwhelming advantage of switching to a clean fuel would be lower emissions.

==Does this article really address whether clean fuels are feasible?=={{OK}}

This article addresses the issue a little bit, though not in depth. It mentions that we really do not have the technology refined, and that the public would have to accept the changes. However, it seems to me that most of the public doesn't really care about clean fuel in the first place, so they would have a hard time seeing the need and taking the effort to switch over.

===Clean Fuels===
{{OK}} 1. High fuel/vehicle costs, current technology is limited, and lower vehicle range are some of the disadvantages to using clean fuel. However, I think that these are minor disadvantages compared to the advantages.

{{OK}} 2. '''It could decrease our dependence on imported oil'''. These fuels emit less hydrocarbons, and the hydrocarbons that they do emit are less reactive and toxic. Using clean fuels could also slow atmospheric build up of carbon dioxide that contributes to the potential of global warming.

{{OK}} 3. Not really, it is suggesting what needs to be done in order for them to be feasible but not a straight yes or no answer.

===Alternative Fuels===

{{OK}} 4. No. 2 Diesel, Biodiesel, Gasoline, Ethanol, Methanol, LPG, LNG, CNG, Hydrogen

{{OK}} 5. Ethanol

{{OK}} 6. No. 2 Diesel, Biodiesel, Gasoline, LPG, Ethanol, LNG, Methanol, CNG, Hydrogen

{{OK}} 7. Hydrogen

{{OK}} 8. Since there is not enough technology yet for you to go out and conduct an experiment yourself, you would just have to compare this information to other sources.

1]The disadvantage of switching to a cleaner fuel is that there are more and more cars on the road every year, and eventhough there are cleaner fuels it is like there is no difference in the atmosphere at all because there are more cars. If the car rate would stay the same there probably would be a difference being made. On the other hand if they dindn't make cleaner fuels there would be that much more pollution in the atmosphere than what they have already cut down on. {{OK}}

2]The advantage would have to be that the cleaner fuels do not emit as much carbon dioxide "green house " gases which causes global warming which would slow down. The new fuels also emit 90% less toxins and ozone forming hydrocarbons. {{OK}}

3]Nothing in the article never says that there are vehicles that the population uses that could use these cleaner fuels. The article did have some really good points and ways to help the environment but if there is a choice for people to buy a new car or use fuels that are already there for them to use more than likely people are not going to buy a new car. That is only if there are not car ready fuels out in the population. {{OK}}

4]Electricity[N/A], Biodiesel, Diesel no.2, Gasoline, Ethanol, Methanol, Liquified Petrolem Gas, CNG, LNG, Hydrogen. {{OK}}

5]The article says that almost every vehicle can operate on gasoline and atleast one other alternative fuel. Gasoline and deisel are the most used fuels. {{OK}}

6]NO.2 Diesel, Gasoline, Biodiesel, Methanol, CNG, LNG, Ethanol, Liquified Pertolem Gas, Electricty and Hydrogen are not rated. {{OK}}

7]The safest fuel would have to be Biodiesel. {{OK}}

8]Althoughy the web site is a government site there is no way of telling if the information is accurate or not but you could get a hold of the EPA to see if the facts are true on the charts. To me it seems like the EPA is the only organization that tells the truth or finds the truth in everything. {{OK}}

1. Some common disadvantages are: {{OK}}

* ELECTRICITY- technology is limited, higher vehicle cost-lower vehicle range or performance, less convient refueling.
* ETHANOL- High fuel cost, somewhat lower vehicle range.
* METHANOL- Fuel could be imported, lower vehicle range.
* NATURAL GAS (METHANE)- Higher vehicle cost, lower vehicle range, and less convient refueling.
* PROPANE- cosst will rise with demand, limited supply, no energy security or trade balance benefits.
* REFORMULATED GASOLINE- higher fuel costs, few energy security or trade balance benefits.

2. It looks like- Very Low Emissions of ozone-forming hydrocarbons and toxics. {{OK}}

3. I dont know what feasible means. But in my opinion the article does explain in great detail the advantages and disadvantages of using clean fuels. If a person was wanting to look into switching to clean fuels this article would more than likely give them a little of the information they need. {{OK}}

4. Well here goes nothing: {{OK}}

*1) ELECTRICITY-N/A
*2) NO.2 DIESEL-8 TO 15
*3) BIODIESEL-25
*4) ETHANOL AND METHANOL-100
*5) LIQUIFIED PETROLEUM-104
*6) LIQUIFIED NATURAL GAS AND COMPRESSED NATURAL GAS-120+
*7) HYDROGEN-130+

5. Gasoline, No.2 Diesel, and BIO-Diesel. But gasoline is the main one. {{OK}}

6. Energy content from least to greatest: {{OK}}

*Electicity- N/A
*Hydrogen-3000 BTU
*CNG- 33000 BTU
*Methanol- 56000 BTU
*LNG- 73500 BTU
*Ethanol- 80000 BTU
*LPG- 84000 BTU
*Gasoline-109000 BTU
*Biodiesel-117000 BTU
*No.2 diesel-128000 BTU

7. Gasoline and Bio-Diesel seem to be the safest, after all we have used them for centurys. {{OK}}

8. Well, I would say its true since it is on the U.S. Department of Energy official website. I dont think they would put somethign inaccurate and untrue on here. But i suppose if you wanted to find out wether its true or not you could write them and have them send you a copy or maybe send an email because most of the time you get a quicker response and its just as accurate as a piece of paper. {{OK}}

1. Somewhat higher fuel cost, fewer energy security or trade balance benefits. {{OK}}

2. It can be used in all cars without changing vehicles or fuel distribution system.{{OK}}

3. Yes and No. The site does give us all of the good stuff that comes with the clean fuel but I feel that it is hiding something. Nothing in this world is flawless especially something that was created by humans. There has to be some sort of major draw back that we're not being informed of.{{OK}}

4. No. 2 Diesel, Biodiesel, Gasoline, Ethanol (E85), Methanol (M85), Liquefied Petroleum Gas (LPG), CNG, LNG, Hydrogen.{{OK}}

5. Gasoline, because just about every vehicle of any sort on Earth can run off of it.{{OK}}

6. No.2 Diesel, Biodiesel, Gasoline, Liquefied Petroleum Gas, Ethanol, LNG, Methanol, CNG.{{OK}}

7. Electricity seems to be the safest.{{OK}}

8. Yes, you could search other sites, read books on fuel stats and referance them with the chart.{{OK}}
