According to a 2011 projection by the International Energy Agency, solar power plants may produce most of the world's electricity within 50 years, significantly reducing the emissions of greenhouse gases that harm the environment. The IEA has said: "Photovoltaic and solar-thermal plants may meet most of the world's demand for electricity by 2060 and half of all energy needs with wind, hydropower and biomass plants supplying much of the remaining generation". "Photovoltaic and concentrated solar power together can become the major source of electricity".
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Photovoltaic and solar-thermal plants will never meet most of the world's demand for electricity by what year?
Ah, so.. unanswerable

At the time of uploading a video, YouTube users are shown a message asking them not to violate copyright laws. Despite this advice, there are still many unauthorized clips of copyrighted material on YouTube. YouTube does not view videos before they are posted online, and it is left to copyright holders to issue a DMCA takedown notice pursuant to the terms of the Online Copyright Infringement Liability Limitation Act.

IndyMac often made loans without verification of the borrower's income or assets, and to borrowers with poor credit histories. Appraisals obtained by IndyMac on underlying collateral were often questionable as well. As an Alt-A lender, IndyMac's business model was to offer loan products to fit the borrower's needs, using an extensive array of risky option-adjustable-rate-mortgages (option ARMs), subprime loans, 80/20 loans, and other nontraditional products. Ultimately, loans were made to many borrowers who simply could not afford to make their payments. The thrift remained profitable only as long as it was able to sell those loans in the secondary mortgage market. IndyMac resisted efforts to regulate its involvement in those loans or tighten their issuing criteria: see the comment by Ruthann Melbourne, Chief Risk Officer, to the regulating agencies.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): IndyMac gave loans to borrower's with what type credit histories?
Ah, so..
