I want to know the answer to the following question:
What is getting cheaper as a result of technilogical change?
All the background I'm provided with is that "A 2011 IEA report said: "A portfolio of renewable energy technologies is becoming cost-competitive in an increasingly broad range of circumstances, in some cases providing investment opportunities without the need for specific economic support," and added that "cost reductions in critical technologies, such as wind and solar, are set to continue."". Is that enough to answer the question?
Answer: no
