More Solar Power Wanted ASAP
from the sun-ra dept
A new report put out by the US petroleum industry warns that conventional energy sources will not be able to keep up with rising demand over the next 25 years. As such, the high energy prices that we're seeing today could stick around. Stark warnings such as this one aren't particularly uncommon, although not all studies are so pessimistic. Still, it's forecasts like this that are driving the high level of investment into alternative energy. However, despite all of the enthusiasm over it, solar energy isn't even close to moving the needle in terms of global (or national) energy consumption. Even the optimistic forecasts call for it to supply 2-3% of US energy use 25 years from now. The caveat is that if there are some major breakthroughs in solar technology, it could take off much more rapidly. Considering how much investment there is into the space, some breakthroughs are likely. It's also worth bearing in mind that these forecasts aren't set in stone by any means. Forecasting anything remains an inexact, if not counterproductive, science. But as long as energy is expensive, as it is today, companies and investors will look for ways to bring more of it to market.Thank you for reading this Techdirt post.

Scare Talk
What's wrong with global warming, anyway? Will anyone really miss cities like NYC or Miami? Will we have fewer snowstorms that kill people? Awww.

Re: Scare Talk
while you make one (1) valid point, that fewer people will die in snowstorms, you ignore that more people will die of heat stroke (which is generally a better killer than snowstorms to begin with), the claim (possibly unfounded) that with global warming will come an increase in hurricanes, and the massive flooding of coastal regions.

While you may not care about anybody other than you, think about the impact of all these millions of people RELOCATING when their city goes underwater. And I'm going to give them your address.

What is the total mass of the polar ice that exists above the water?
What is the mass of polar ice that exists below the water line?
What is the factor used to account for the fact that water has an increased volume when frozen? (Ice Floats)
What is the total volume of space between the existing sea level (average... I'll cut you a break), and within 500 feet of the tops of the Himalayan mountains?
You may begin your simple addition and subtraction now.
This WILL be for a grade....

Re: Re: Re: Scare Talk
the 1930's was the epitome of "global warming" scare talk, yet the world didn't end.
Sure we can fuck up parts of the earth with pollution, but it's just to big of a mass for us to totally break it.

Comboman, you're right in that throwing ice in a glass of water will not raise the water level when it melts, this also holds for the ice mass that sits in water. However when discussing the earth you're neglecting the amount of polar (and non-polar) ice that does NOT sit in water. A prime example of this is Antartica. Huge sheets of ice, that are quite thick, sit atop land. If those sheets of ice melt then the ocean levels WILL raise. No where have I seen estimates that come anywhere close to what Chronno mentions but I have seen scientific estimates of 100-200 feet above current levels if all of the ice caps melt.

1) earth's climate is changing.
2) while a portion of said change may be part of a cycle these changes are beyond the normal observed scope of that the cycle.
3) There is not enough ice to submerge all land mass, in fact a lot of ice is floating, so sea levels won't rise dramatically.
4) Sea temperature and salinity will change as ice melts.
5) Solar energy is never going to offer 100% of current energy needs.
6) A combination of renewable energy sources will eventually be able to meet most if not all of energy demands.
7) Efficiency will continue to increase as energy demands increase.
8) As countries develop energy demands increase.
9) As populations increase energy demands increase.
10) Hey look, China.
11) Cars on average are no more fuel efficient then they ever have been. In fact many are less efficient than the Model-T (which got 25mpg).
12) In the US commutes have steadily increased.
13) Global warming does not mean things just get hot, it means extreme weather patterns.
14) Most homes are not significantly more efficient and as highs and lows have increased so has energy demand to maintain comfortable temperatures.
15) Unless 100% of energy needed is produced locally effects of non-local power needs effect cost and supply of local power.
16) Earth will evolve and survive.
17) There is no guarantee that we will survive with it.

Re: Scare Talk
This time you're just ill informed as to the effects of global warming. If global warming is as bad as some people - Gore - say (which I highly doubt), the issue is that it'll trigger an iceage.

11) No, modern cars are NOT less fuel efficient than the Model T. If you restrict modern cars to the maximum speed that the Model T was capable of, you'll find that they are much more efficient. The *apparent* lack of fuel efficiency is due to modern driving *conditions* (i.e. stop and go rush hour traffic, 75 MPH speed limits which are routinely exceeded, seating capacity for 7...) which the Model T did not have to deal with.
16 & 17) Define "survive", and if you think we should care about the Earth surviving without us, you're crazy.

Re: Re: Re: Scare Talk
"Scientists notice a trend" is not, despite it being FROM scientists, scientific data in this case, it is all theory. Give me a scientist that has been alive for a thousand or so years, and measured weather statistics every day of that, and perhaps we'll have something accurate.

Re: Jon says silly things
He's referring to the fact that the planet has gone threw several (At least two that I can think of) extinction level events.
One where globale worming happened causing the methane "ice" under the ocean to melt sending more greenhouse gasses into the atmosphere lowering the oxygen levels to I believe 5% where it is normally 20-30%. Thus suffocation.
The second was what killed the dinosaurs. A giant asteroid, supposedly causing the gulf of Mexico, which superheated the air around the crash site and sent a cloud of dust into the atmosphere blocking out the sun, killing off most of the plant life. No plant life kills off the herbivores witch in turn kill of the predators that feed on them.
The planet survived every time. All he really is saying is that the hippies that say we're killing the planet are wrong. It's not dying, we are.
Yes I was wrong about the ocean levels, but there are so many different statistics online, and even here, that I don't even know what is right any more.

re: what are solar panels made of?
Wind technology is actually less environmentally harmful to produce and (although some say an eyesore) work both in the day and night.
Just my two cents.

Re: Re: Re: Re: Scare Talk
Wrong, as some of the sea ice is floating above the water line.
The sea ice will melt just as well as land ice. That land ice water is gonna go somewhere, right?

Think about it, a fuel that lasts 5-20 years before recharging, the only daily waste is heat (steam anyone?)
OK, eventual waste products that last several hundred years (unless you melt down in vitrification to a 1 meter block of glass, which includes the low-level waste like suits, gloves, trash)
Then put that glowing block of glass inside a mountain in Nevada (kinda hard for terrorists to steal a 1 meter block of glowing glass) where it is still available for recycling when we perfect the technology.
MUCH better than a mountain of toxic fly ash (where do you put THAT?), or mounds of heavy metals from making solar panels, or NO2 & acid rain from oil burning.

Re: Re: Re: Re: Re: Scare Talk
Ahhh .. ice floats because when water freezes into ice it expands and the resulting ice is less dense than water. The mass of the water displaced by floating ice is exactly equal to the mass of the floating ice. When the floating ice melts it will shrink back down to its original size and exactly fill the "hole" in the water which was occupied by the submerged part of the ice.
All those investors in solar power should consider that the industry really needs a break through and the odds are that it will only be one company out of all of them that makes that break through. Solar power can be a business with a great collective future and yet every single available investment opportunity in that space can be a dog.

Logic?
So what your saying is old people are more susceptible to temperature changes but as temprature goes up less people die. That means the hotter is gets the less likely a older person would be to die from something like heat stroke?
Seems like your contradicting yourself in your post. I haven't looked at the statistics myself, but I would gather when it is 110 degrees out and a older person doesn't have AC they run a high risk of heat related death.

Re:
1-the earth used to be covered in ice and they found crocodile bone fossils near the north pole. so?
2-see above and tell me what normal is- time period might be nice since the earth is way older than man is.
3-the core of the earth has a large mass of water recently found in it...but no one knows if all the water could cover the earth- really!
4-Cannot argue there
5-orbiting satellites might be able to do it.
6-define renewable
7-you then counter this later on so it leaves me puzzled
8-Germany demand has fallen- (assumption)also counters #7
9-counters #7 but okay
10- I see it...so?
11- An 8000 pound tahoe hybrid tahoe gets this mpg- you are wrong
12-wrong- populations are steadily going toward cities and have since 1900
13- that is the new lingo- from global warming to climate change so they can blame everything
14- prove that highs and lows have increased- I dont believe thermometers that have accuracy of +/- 1 degree can be used to confirm a .4 degree rise in temperature as is stated currently.
15-nope- saudi oil costs 3 bucks a barrel to pump out of the sand- way cheaper than local energy production
16- off topic
17-off topic

Re: Jon says silly things
Ever drive a car around at less than 30 mph? It gets terrible gas mileage at those speeds...even modern cars. At low speeds modern engines have higher Break Specific Fuel Consumption and they are putting more energy into turning the alternator/air conditioning/overcoming driveline friction than they are putting into the wheels of the car. Optimal speeds for most cars is around 50 mph. Your other comments about fuel economy are correct.

Re: Re: Logic?
No, he just doesn't understand how statistics works and the difference between correlation and causation, plus his statistical evidence was based upon referrals which have nothing to do with deaths.
If you had half a brain cell I am sure you could point that out too.
