A recent report from the International Energy Agency is offering a glimpse of the future growth potential that solar power offers.

According to the IEA, solar-generated electricity could account for as much as 25 percent of global production by 2050. This week, the energy organization released a report that includes roadmaps for both photovoltaic technology and concentrating solar power. Both of these options are becoming increasingly common around the world, especially when it comes to utility-scale projects that can power thousands of homes.

"The combination of solar photovoltaics and concentrating solar power offers considerable prospects for enhancing energy security while reducing energy-related CO2 emissions by almost six billion tonnes per year by 2050," said Nobuo Tanaka, executive director of the IEA.

In total, both solar technologies could generate 9,000 terawatt hours of energy by 2050. Areas with the sunniest and clearest skies are said to be well suited for concentrating solar projects, while photovoltaic technology is cited for its potential for on-grid distribution and off-grid production in more remote areas.

<not much more>

science illiterate cretins!

:D

1. got to keep the beat in for teh hoppin' cretins

yeah

[jpak]

2. 1..2..3..4..cretins wanna hop a some more

4-5-6-7

all good cretins go to heaven

[Systematic Chaos]

3. If you were any more full of yourself you'd be a fucking paradox.

:eyes:

[jpak]

4. D.U.M.B. everyone's accusin' me

:D

5. Could reduce emissions by 6 billion tonnes per year. For perspective, we release 30 billion yearly.

Which will go to over 40 billion tonnes yearly by 2030.

Sadly this is the EIA, which is dismissed on these forums.

6. Wait -- and destroy petroleum markets?? Are you nuts??

7. It's pretty telling that 10 years after solar soothsaying started here, we still have...

...more solar soothsaying.



The number of "solar will save us" anti-science cretins who can write a sentance to promote their solar fantasy without a conditional verb is still what it was ten years ago zero.

But how's that wind powered hydrogen HYPErcar SUV running after the grand success of the Utsira wind to hydrogen progam.

There must be tens of millions of them in Norway now, no?

8. if this is so easy, why arn't poor countries doimg it?

many poor countries have power
shortages

[jpak]

10. They are - Kenya, India, Bangledesh et al.,

yup

[Statistical]

11. What % of generation comes from solar in those countries?

Solar power generated 0.02% of world's power in 2008 (I don't have a 2009 number).
It could double 5 times and will still be less than 1% (0.64%).

12. You are right, it is impossible for solar make any contribution to global energy production ever

the IEA ARE a bunch of hoppin' anti-science cretins!

yup!

:rofl:

[Statistical]

13. I never made that claim.

It simply won't for the decade and won't be more than wind is now in 20 years.

The IEA report is UP TO 20% to 25% in 2050. That is four decades from now.

Now doubt solar installs will continue to grow every single year but given the tiny amount of installed solar even with 40%+ annual growth rates it will be a long time before it even cracks 1%.

[jpak]

14. It's absolutely and mathematically impossible for solar to make any significant contribution

to global energy production

It can't be done

the end

:rofl:

[Statistical]

15. Who said that? Oh yeah only you.

Why are you so anti-solar?

[jpak]

17. Only mocking the stupid anti-solar argument

yup!

16. Here is the actual roadmaps

It is actually two roadmaps.

PV Solar:

Concentrating Solar:
http://www.iea.org/papers/2010/csp_roadmap.pdf

On a long time horizon (40+ years) CSP is the more interesting & useful technology.

The potential to store large amounts of energy and combine it with natural gas (to improve capacity rate of the expensive turbines) has a lot of potential. CSP can actually be used for baseload (24/7 output with high capacity factor) given a large enough thermal storage it also can be used as massive peaking plant by combining a large thermal storage with even larger turbine (essentially concentrating 6-8 hours of daylight into 2-3 hours of peak power output).
