Solar Thermal Energy
According to the estimates made by the U.S. Department of Energy the world in the year of 2010 will be using 50% percent more energy than FY of 1991.
This would create 50% more COČ emission and excess heat to warm the atmosphere to cause the well known greenhouse effect.
However this figure willl be lower in the OECD countries because of the government strategies introduced by their governments towards clean and renewable energy use.
U.S.A. estimates shows that the average solar heating pays for itself in 4 to 7 years. The saving increases over the years due to increasing electricity rates. It is expected that to produce electricity from the solar thermal systems.
will be economically competitive with the conventional electricity-generating technologies by the year 2000.
U.S electricity average cost price to the residential consumers is $0.08/kWh and $0.05 for industrial users.
By the middle of the next decade, some solar thermal electric technologies could be
producing electricity at $0.06 to $0.07
per kilowatt hour (kWh).
