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.
When comparing price per watt, capacity factor should be considered in the overall cost comparison. For instance; if the cost of solar is $1 per watt, when including an average capacity factor of approximately 20%, this cost rises to $5 per watt when compared to a hypothetical source that produces energy consistently.nstallation costs [edit]. Coal power plants are generally one of the least expensive sources of electricity by this measure, at a construction cost around $2.10 a watt.
