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 a solar electricity system varies a lot based on whether tax credits or rebates are available to you. It's as cheap as free, where incentives pay for 100% of the cost of the system. On the other extreme, with no incentives and a higher-than average cost of install, a system might cost $53,000.
