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.
In addition, costs for fossil fuels may creep up due to raw material costs, shipping costs, and possibly carbon dioxide taxes. At an installed price of $1.25 per watt, the cost of PV solar is always cheaper than coal. At $2 per watt, it is cheaper after year 40.At $3.00 per watt, it is cheaper about year 80. It is expected that PV solar costs will reach conventional coal parity by 2017. As a result, no new coal plants are expected to be initiated, although some current coal plants will likely be upgraded.he chart at the left shows the average cost of electricity for 2014 by consumer group per the EIA (the US Energy Information Administration). For 2014 the average residential cost was 12.50 cents per kilo-watt hour up 3.1% from 2013. Commercial was 10.75 cents and industrial 7.01 cents.
