This is partially true but then again when you look at the whole picture the saving is no-where near what you would expect.
First you have to look at the resources used in making the solar panels in the first place. Then there is distributing them and installing them, all of which would use a tremendous amount of resources which you have to then offset against any savings the panels would make over their lifetime which again isn't all that long and then they have to be replaced using more resources.
Good points, but this is based on the assumption that solar panel technology won't change when it seems to be at a dramatic rate currently. A California based company is making paper thin solar technology using nano technology that is supposed to cost a fraction of the cost of current technology and be slightly more efficient.
If solar panels at this point were at their peak efficiency and dirt cheap I'd agree with you, but right now there is so much more room for improvement that we can't discount it for it's costs.
At the same time, people have been making money off their solar panels for years now. Remember the government pays back half the costs in setting up your home with a solar setup. These people have saved not only on their bills but they are selling power back to their electricity providers.
Then you need to have power stations online and generating electricity anyway in case of poor weather reducing the efficiency and output of the solar panels.
This will always be the case for sure, especially for homes in areas that are prone to a variety of weather. But I think you'll agree that the point is not to become energy independent in our own homes. Rather, just to reduce the load on power stations.
The problem is, at the moment whatever anyone claims there just isn't a viable large scale alternative to the way we generate electricity. If there was we wouldn't need to have these debates, and tinkering around at the edges isn't going to make any real difference at all.
If climate change really is such a threat the only way to deal with it is a wholesale change in peoples lifestyles, massive reductions in energy consumption to levels that could be currently sustained by clean energy generating sources. None of that will happen by leaving the general public to voluntarily and gradually changing their lifestyles, it would have to be enforced by governments, none of whom are willing to do that just yet
I think that the "cost" motivator will push a lot of people. The same applies to electric cars.
It's estimated that the batteries in the Roadster cost $80K (Tesla has never said it themselves). If battery costs go down to 1/10 that then everyone would jump on a sportscar that can go 0 - 60mph in 4 seconds for only $40K. It is a big "if" but we've seen crazier things (like computer technology improving at the rate it has).
Well......this post lets me know that you did not read my post about reading your original post.
How so?
Most electric cars aren't shipped 2 times around the world, but the Pruis is probably the most popular (at least here in Australia) which is who shifts the most and is being the most wasteful
So what does this have to do with electric cars being wasteful? Again, a poor argument.
Yes, the Nickel out of the batteries is salvaged, but you'll find that Toyota make their own nickel to put in the batteries. I just read an article saying they produce 1000 tonnes a year and has ruined the surrounding ecosystem.
You aren't likely going to see Toyota batteries used for future electric cars. There are plenty of far more effecient batteries coming up from even big players like BMW.
If by "gas" you are reffering to LPG - let me remind you of what the P stands for in that.
Yes, it is reducing the rate, but it is not long term solution.
Of course, and I never said it was long term. In fact the whole time I'm insinuating that it's the worst case scenario.
And I still strongly hold the idea that hydrogen is the way foreward.
It will be another 10-15 years before Hydrogen FCs become viable for the public, maybe you are getting confused with Hydrogen ICEs.
