Condensation on windows is a problem for many homeowners, and it can occur in all types of buildings. Singled-glazed windows are a primary cause of condensation, though many modern day double-glazed windows do condensate. This is usually due to poor manufacturing and inadequate installation.
To put this in context, construction of a 500 MW power plant for the different energy sources would cost around: 1  $1.8 billion for a solar power plant. 2  $1.5 billion for a typical coal plant. 3  $2.6 billion for a coal plant with CCS. 4  $482 million for a natural gas plant.
The cost of solar depends on the size of your house. The average residential system is 5 kW and the current average price per watt is $4, so an average 5 kW system would cost $20,000.our quote will vary. If a 5 kw system costs $20,000 before rebates, the CPS Energy residential rebate would bring this cost down to $13,200. After the 30 percent tax credit is applied to the remaining balance, the final cost would be $9,240.
