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 providing electricity from wind and solar power plants has plummeted over the last five years, so much so that in some markets renewable generation is now cheaper than coal or natural gas.ccording to a study by the investment banking firm Lazard, the cost of utility-scale solar energy is as low as 5.6 cents a kilowatt-hour, and wind is as low as 1.4 cents. In comparison, natural gas comes at 6.1 cents a kilowatt-hour on the low end and coal at 6.6 cents.
