[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]Huge SUVs like the Chevy Suburban. Even if you have a bunch of kids, the size of this SUV is excessive and the gas mileage is horrible --15 mpg!!

I don't understand how so many educated people in this area can make the decision to buy these gas-guzzling vehicles. It isn't ignorance of the facts. These drivers (1) know that climate change is real; (2) know that SUVs are a non-trivial component of CO2 emissions; and (3) know that fossil fuels are a finite resource that could eventually be exhausted. Armed with this knowledge, I don't understand how educated people can purchase a big SUV.

Soon all these large SUV's and full size trucks will be electric. What will you have to complain about then?[/quote]

This will be better than our present situation, but there will still be a lot of CO2 released in the production process. Some SUVs weigh more than 6000 pounds. This is more than twice as much as compact car. 6000 pounds -- and the associated CO2 -- is excessive.

We not only need to electrify the economy, but we need to downsize our houses and cars, and reduce our tendency to buy lots of stuff that we barely use and that toss in the rubbish bin. These changes are needed even in the absence of climate change. They are needed to reduce our energy requirements so that they can be served, in the long run, by renewable sources. Fossil fuels are finite and will not last forever. Nuclear power is also a finite resource.

Here is an excellent book written on sustainable energy rewritten by a British physicist named David MacKay. He has since passed away, but his ideas remain valid. The book examines if renewable resources -- developed to their theoretical full potential -- can satisfy our present level of energy consumption. The answer is clearly NO. So significant lifestyle changes are necessary or, alternatively, we need to gradually reduce the human population to a sustainable level.

Thanks for the link but the answer from that link is not “clearly NO” but rather “most likely YES”. The estimates of renewable energy supply is just slightly (5-10 percent) less than demand. Given how crude these estimates are it is within the margin of error[/quote]
