"Two important caveats, of course, apply and should be obvious to the readers of this newsletter:
• First, neither wind nor solar runs dependably around the clock, 24/7, as a coal- or gas-fired or nuclear plant normally does. Hence while the 3 cents/kWh solar price may be half that of a coal or gas plant, it must be backed up in one form or another so it is an apple vs. orange comparison; and
• Second, the low prices mostly apply to developing countries where new capacity is needed and can be added at scale, which results in lower prices."
So, continue researching but please, add a little more balance in the reporting.
