However, this news item http://www.scienceworldreport.com/ar...ate-change.htm warns that climate change could have more devastating global consequences. Of course, it is difficult to reduce energy use in the way that is often advocated as the way to limit carbon emissions. We need a strong economy - and the kind of industrial capacity that supports adequate military capability to defend liberty from its many foes. But, as I've pointed out, that is hardly an insoluble problem. There's such a thing as nuclear power - and breeding fuel from Uranium-238 and Thorium-232 should give us plenty of time to solve the more difficult problem of fusion power. John Savard I do my daily commute to work and back in my Chevy Volt using only electricity. It consumes a mere 200 watts per mile at a cost of less than 1 cent per mile. Units! It cannot do any number of watts/mile. From published figures I reckon a Tesla typically uses about 400Whr = 1.5MJ per mile eg http://www.fueleconomy.gov/feg/bymod..._Model_S.shtml All courtesy of the Com Edison Byron Nuke plant and local windmills. I get to work just as fast as the guy in the Porsche SUV while he gets a measly 8mpg in his gas hog. I fill up every night at my friendly 110 volt plug in my garage and next morning the "tank" is full again, ready to covey me another 45+ miles. Which is fine if you never have to drive any real distance. I have great torque and nothing spews out the tailpipe, there is not a series of explosions pushing this vehicle forward, just the application of Maxwell's equations and some magnets doing their work silently and very efficiently. There is some quite nasty battery chemistry involved and battery capacity is not exactly stellar nor is long term life expectancy. In the future would I consider going back to a gasoline car? Never! Ask any Volt owner and to a person they will tell you the same thing. Right now brand new ones are selling for less than $20k at our local dealer. Pretty good deal all around if you ask me. How are they making a profit on them at that price? -- Regards, Martin Brown |

It's really too bad that most of its economy is critically dependent on tourism which inevitably involves cruise ships and air travel, both rather carbon-intensive activities. Can you say "hypocrisy?" I bet you can. |

All courtesy of the Com Edison Byron Nuke plant and local windmills. *AND* from the coal plants located nearby. I get to work just as fast as the guy in the Porsche SUV while he gets a measly 8mpg in his gas hog. Most people don't drive 8-mpg SUVs. Or haven't you noticed? No coal plants serve this area. Incorrect. Illinois is full of coal plants. |

They are a great deal more energy efficient and carbon friendly. But we can't look at them at their current state of development, we need to look at where the technology is headed. And that technology development depends on subsidies and early adopters. People driving electric vehicles and hybrids are driving the technology forward. They are helping redefine the norms. It's not so much about how efficient your car is today, but what things are going to look like tomorrow. |

It's really too bad that most of its economy is critically dependent on tourism which inevitably involves cruise ships and air travel, both rather carbon- intensive activities. Can you say "hypocrisy?" I bet you can. They need both the sea level to stay put, and their tourism-dependent economy to thrive. For them to conclude, from this, that carbon emissions do *not* contribute to global warming - is wishful thinking, not integrity. What they need does not change how the Universe works, so the question of whether or not carbon emissions will lead to a rise in the sea level can only be answered by a scientific investigation of the evidence - not by political choices. They had tourism, no doubt, even back in the 1950s, before anyone noticed a global warming problem. Presumably, if cruise ships can't be converted easily to carbon-free energy sources, there are plenty of other human uses of energy which can. For example, electrical utilities don't have to burn coal, oil, or natural gas - where hydroelectricity is not available, nuclear still is. It's not hypocrisy to note that carbon emissions are a problem, but one has a need for certain high-priority ones to be allowed. Hospitals will still need to burn fossil fuels for their emergency generators too. Maybe converting the utilities will be enough, and we won't even have to switch to electric cars - which are, at present, inferior, just as CFC-free refrigerators are inferior. John Savard |
