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.
According to GTM Research, the cost of utility-scale solar projects has fallen 67% in the past five years; $1 per watt would be another 44% in the next couple of years. The resulting cost structure is leading to highly competitive prices for solar energy versus fossil fuels. First Solar says that bids for solar projects are now in the $0.04-to-$0.05-per-kWh range, which is less than you can build a fossil fuel plant for, no matter the source of energy.
