If pursuing alternative energy (solar, wind, etc) have a lot of benefits, why do some people still oppose it?

Because a lot of people have a lot of money riding on you using a petrol fueled car, coal fueled electricity, etc, etc. And the people with the most money generally win the argument!

I don't know if many people are against it but we still have to learn a lot. The use of these sources is still more expensive than using fossil fuel. But rising energy costs, and the inability to calculate energy costs is pushing us onto the road of more research and application of clean resources. This is an inevitable trend. Oil reserves are dropping and demand is growing. So if we want to survive we need to figure out new ways. And this is going to be the next big boom and paradigm shift. Green is big money. Investors famous for supporting start ups like Google, Netscape and Amazon are now throwing themselves on green investments. Its only a matter of time. Hans

I think part of it is there is still a lot of money to be made in oil. And the biggest profits are yet to be realized. When it can be made to look like oil is scarce or hard to get, the price will sky rocket, but only if we are still dependant on it. So Oil producers are spending a lot of money to stop legislature or research toward alternate fuel vehicles or fuel efficiency. I also think there is a lot of misinformation out there I've seen so many posts about the high cost of solar panel. I speak from experience. I have them and I will break even at about 6 years, that means I'll have free electricity for at least 14. Even without the rebates I would have broken even before 10 years, still 10 years of free electricity. They work anywhere you have sunlight, Germany which isn't near the equator is one of the top users of solar. There is the whole eye sore problem with wind turbines, but that is a perception issue. I think they are beautiful, we got use to looking at high tension lines we will get used to the look of wind turbines. Many people don't think we should subsidise the industry. I would rather may tax dollars go toward clean energy which will benifit the whole nation than many of the other things the goverment spends our tax money on that only benifits a few. It does creat new jobs, in Ca we have a lot of people who were able to find jobs in the solar installation field that would be out of work now because of the slowdown of home building. Not to mention all the research and development jobs.

For the same reason people were against motorized vehicles when they first came out. No matter how much they say they don't want to go back to the stone age they are actually afraid of embracing something new (and most likely better). Change is hard for many people.

When you switch to an alternate source you never can predict what other problems may arise.

Yes to all those questions. It is just that we are not quite there yet withe the technology and people are against it beacuse it would get rid of there own businesses. Also, some people son't believe global warming and scarce resources even exist so they see no point in spending money for that.

It's much more expensive and less efficient. For example, solar panels are very expensive. To use the energy from them, you need to convert it from DC currents to AC currents. This is rather costly, and converter boxes take up lots of space and energy. Furthermore, solar panels aren't efficient unless you have lots of sun, like in states like California or places near the equator. Wind energy has its benefits, but many think of windmills, etc. as eyesores; furthermore, there are few places where windmills can be placed. So it's hard to get a lot of energy from wind. Dams are another source of energy; however, these haven't been built for years. Often, these dams are super expensive and inefficient to build or repair. Furthermore, they may mess up mating/migration patterns of fish. And nuclear energy is also a solution, but its wastes are very toxic, and cannot be stored or disposed of easily. Furthermore, contamination from radioactive materials is very toxic and dangerous. [e.g. Love Canal] I'm sure that if people tried, they'd be able to find more efficient /cheaper ways to use renewable energy sources. But people are lazy, and using fossil fuels is relatively easy and cost-efficient.

1) It's expensive and NOT free. 2) It may expel CO2 into the air but it would disturb many pristine environments around the globe. 3) We could drill in the USA and completely rid ourselves off of Middle Eastern oil. We import most of our oil from Canada and Mexico. 4) They only work when the sun is shining or the wind is blowing which makes them unreliable as a primary energy source.

Interesting previous answers, but some are flat misleading. The reality is, even if windmills are free energy...per se....the wind isn't always blowing, you still need petroleum products to grease the gears, there's also been studies that show that the turbines themselves and transmission lines effect people that live near them. Then there's the asthetic appeal, who wants to litter the countryside with windmills ? After all Ted Kennedy himself said he doesn't want to see them off his east coast. I guess the rich are priveledged to live in pristine area's and not have to compromise for alternative energy while the poor get the coal plant in their back yards. Solar is good, however the Polysilica is expensive, so much so that even the cities and companies offering subsidies to install them have cut back the money they will give you because its costing them too much money in revenues. They've even limited in areas how much energy you can actually sell back to the utility companies. I wo'nt touch the ethanol arguement, if you do'nt know by now how bad ethanol is, how inefficient and how highly subsidized........"SUBSIZED" meaning the government is making you and me pay for it through out tax money. well then you really don't deserve to be on the enviromental forums since your uninformed and out of touch. The most efficient and economical way to power cities is nuclear power, that is the only source that can actually power the whole city. T Boon Pickens might whine about how oil can't solve the problem for 10 years, but he himself said that ths wind idea will take 10 years...and in the end...only supply 10% of the needs. That doesn't sound feasible to me. As for vehicles...sure, we can run them on natural gas...but duh....its still a fossil fuel, and i've seen indications that running out of fuel in a NG vehicle causes harm. So why would we transform all of America into such a problem ? We already have deisel engine technology. Its been proven that these engines can be converted easily to run on vegitable oil. There's companies out there using vertical grow systems and bio reactors that make biofuel out of algae. Vegitable oil for cars from a source that isn't a food. So no more waste of corn, no more effecting the economy and cost of living, no requirement to retool auto dealers across the nation for a different technology or forcing people to buy a different and new car that they are not sure will perform like the old version. I support solar , I think windmills can supplement small facilities but for the most part they are limited in usefullness. But lets not demonize oil all because the democrats and liberal media have told you to. We will always need oil, to make plastic containers, medicine, lubricants, makeup, etc, etc. It is an integral part of our life and as technology inproves...so does pollution. Lets not also forget that you can't just drop a technology or economic sector and change it over night. It has to be phased out. If gas disappeared tomorrow...how would you get to work ? how would electricity be generated for your home ? or work ? What of the millions of products that exist due to oil extracts ? I'd bet your not even ready to go totally natural and "green" without any oil or oil products in your life. Industry making money from oil can't just simply vote to go out of business. When someone comes up with something feasible to replace oil, then it will happen, but nothing has been that good as a replacement. If no one used oil, the companies wouldn't be in business in a free market. When someone comes up with a sure thing, then gradually we will change.
