OT - Senate Republicans vote to kill Obama's jobs bill..Why DoRepublicans Hate America?

I knew I could count on old "Buggy Whip" Johnson to oppose green technology and stand tall to keep 19th century forms of energy number one on America's energy menu. But sadly for him and the old tech, the modern people are moving away from burning things to make energy. Maybe in a couple of decades Buggy Whip will see you don't have to burn stuff to make energy like he always thought. But he's not going to see that for a long, long time. Like all right wingers he's got his head firmly set...to look to the past. Hawke I am all for green energy, but only when it is cost effective. I have been adding insulation to our house because it decreases the amount of energy I need to live comfortably. But right now natural gas is cheaper than it has been for years and we have about a hundred years supply at our current rate of use. Solar energy is not competitive with natural gas. It takes too much energy to make the solar cells. So all the trendy people are going to things like electric cars that either use gasoline to generate the electricity or use power generated mostly by burning coal. At the rate solar energy is developing, you will be using power from burning things until you die. It sure is not going to be here in a couple of decades. Meanwhile the Keystone pipeline would be transporting 590,000 barrels per day. Have you any idea of how much energy that is? And how long it will be before solar energy will be supplying that amount of energy? Dan |

If you would watch that interview with Clinton I told you about on Book TV you would have a much better idea of how soon solar would be cheaper than oil. You want me to take the word of a politician about the future of solar energy. You do realize the government has no good idea. If they did they would not have loaned money to Solyndra. I'm only paraphrasing but he was saying that every time we put in another solar energy farm the cost goes down 30%. He said that in five years it'll be as cheap as oil. He said Solyndra went down because new technology changed so fast that it made them unprofitable. Every year oil is going to keep going up in price because it's getting harder and harder to get it. All the easy oil is gone. Oil tar sand is profitable when the price gets to around 10 bucks a gallon. By the time we reach that level solar and wind will be cheaper. Solar has been just five years away from being cheaper than oil since about 1972. And I expect it to be just five years away when I die. Oil and natural gas have been getting cheaper not more expensive. The drilling techniques have improved so that oil and natural gas in shale is now profitable. Oil from tar sand is profitable when crude is about $80 a barrel. So oil from tar sand is profitable right now. That is why they want to build the keystone pipeline. Have you not been paying attention. A barrel of oil is 42 gallons so you are off by a factor of 5. The other problem with solar is of course the power goes away at night and when it is cloudy. So solar power is not economically feasible in a lot of states. You can build solar farms in desert regions, but then you need transmission lines. And transporting electricity long distances means significant power losses. You lose about half the power in transmission lines. So you need twice as much power if you locate the solar farms in Arizona and send the power to Texas. When I was in grade school ,the known oil reserves were good for about 15 years. Now some 60 years later the known oil reserves are more. I can find places on the internet that say the oil reserves are good for 140 years. I am not sure I believe that, but it is closer to being right than "solar power will be cheaper than oil in five years" http://www.radford.edu/wkovarik/oil/ "To begin with, one of the most revealing speeches about world oil reserves went unremarked in 2006. The head of the world's largest oil company, Saudi Aramco, said: “We are looking at more than four and a half trillion barrels of potentially recoverable oil. That number translates into 140 years of oil at current rates of consumption, or to put it anther way, the world has only consumed about 18 percent of its conventional oil potential. That fact alone should discredit the argument that peak oil is imminent and put our minds at ease concerning future petrol supplies.” " Clinton also said in North Dakota alone there is enough wind power to provide something like 24% of our energy needs. What we need is a modern electrical grid to make it happen. So what do you want to do? Stick with trying to get more fossil fuels, which gets harder and more expensive all the time or just go for the newer cleaner fuels. If you choose to go the clean route all the old energy industries and their allies call you every name in the book. I can understand why. They're going the way of the buggy whip. Hawke What I want to do is let oil, natural gas , solar , and wind power to compete. There is certainly no need to rush into solar or wind power. There is no need to have government programs to subsidize any of the energy sources. There certainly is no need to help companies as Solyndra. The cheapest source of energy will change over time, but right now it is natural gas and it looks like it will stay that way for another thirty or more years. Dan |

You do realize the government has no good idea. if they did they would not have loaned money to Solyndra. Apply that logic to business. Why would people loan money to any business when they go bankrupt so often? Do they have no good ideas or why would they waste money on a bad idea? Could it be you have to take some chances to get ahead and if you do you will incur losses whether you are a government or a business.

And transporting electricity long distances means significant power losses. You lose about half the power in transmission lines. So you need twice as much power if you locate the solar farms in Arizona and send the power to Texas. So to get solar power to work all over you need a new high tech grid. Yeah, I thought I said that. The point is that aside from the price there are a lot of other things wrong with fossil fuels. Knowing this a smart man would want to change to clean renewable energy sources as quick as possible. When I was in grade school ,the known oil reserves were good for about 15 years. Now some 60 years later the known oil reserves are more. I can find places on the internet that say the oil reserves are good for 140 years. I am not sure I believe that, but it is closer to being right than "solar power will be cheaper than oil in five years" I wouldn't stake my life on that if I were you. Besides that don't you understand that world's demand for energy is growing at an exponential rate? What do you think the world would be like if we amped up production of fossil fuel use to keep up with that? In addition, the oil that is cheap and easy to get has been found and is declining. What we age getting now and in the future is going to be harder to get and will be more expensive. As a businessman wouldn't it be wise to see that and plan to switch to other fuel sources ASAP? http://www.radford.edu/wkovarik/oil/ "To begin with, one of the most revealing speeches about world oil reserves went unremarked in 2006.

You trust them? Be my guest, and if they have so much oil how come the countries in the Middle East are trying to get nuclear power? Could they know their oil is running out and don't want us to know that? Clinton also said in North Dakota alone there is enough wind power to provide something like 24% of our energy needs.

You can hide your head in the sand and pretend there is no damage done by using fossil fuels but the science says otherwise. The need to switch to clean fuels is critical. It must be done immediately. Hence the reason the government has to get involved. If it were left to the market place there is not telling how much it will cost us down the road. Better to bite the bullet now and change over to clean energy. I just heard the navy did a test run on a ship using a combination of diesel fuel and bio fuel and it was a success. They are in the process of changing too. You just want to leave everything to the market. I don't. It can't wait. The market can't solve all our problems. Didn't you learn that from when Bush was in office? Hawke |

The Saudis have been lying about their oil reserves for years. You trust them? Be my guest, and if they have so much oil how come the countries in the Middle East are trying to get nuclear power? Could they know their oil is running out and don't want us to know that? So what about the vast amount of oil in Canada? What a crock. You can hide your head in the sand and pretend there is no damage done by using fossil fuels but the science says otherwise. The need to switch to clean fuels is critical. It must be done immediately. There is no doubt that CO2 in the atmosphere is a green house gas. But did you know that without CO2 in the air, the earth would be too cold? And did you know that a significant amount of the CO2 going into the atmosphere is coming from underground coal fires. So if getting rid of CO2 sources needs to be done immediately, why is no one extinguishing the underground coal fires. That would be a relatively cheap way to cut the CO2 going into the atmosphere by about 40%. I just heard the navy did a test run on a ship using a combination of diesel fuel and bio fuel and it was a success. They are in the process of changing too. BFD. Burning a barrel of biofuel puts the same amount of CO2 in the air as burning a barrel of regular diesel fuel. Dan Hawke |
