Your Questions About Wind Generators Cost
Mandy asks…
What is the establishment cost for a coal burning factory?
I need this for a science assignment. Holy crap do I hate science.
So yeah, what is the establishment cost to set up a coal burning factory? (Where the coal is transferred into energy)
admin answers:
The current establishment cost of a coal fired power station is about $2000 per kilowatt of power produced. Over a 50 year life; this is quite low compared with establishment costs for wind and solar power generation, and a lot (hundreds) of wind generators are needed to produce the same power output of a large coal powered generator. This is why it is proving difficult to replace coal for large scale power generation.
Here’s a wiki ref:

Laura asks…
How can laws of thermodynamics applied to the system of wind power?
Apply the 1st and 2nd laws to the wind powersystem. State what conclusions (environmental, economic…) can you draw from applying the 2 laws.
admin answers:
Energy conservation can show how efficient/cost effective a wind power generator can be.
