Be more specific
Without knowing what the items are it is hard to know which CFLs can reduce the cost of energy. The items being referred to need to be given.
No. made it cost more. :(
You can calculate the cost of your energy savings when you reduce the rpm's from 3450 to 2350, by dividing 3450 into the cost of fuel. This will give you a fuel costs per rpm. Take the cost per rpm and multiply it by 2350. Subtract this number from your original cost and you will have your energy savings.
Yes, but it's not as widespread as photovoltaic rooftop installations despite the potential cost and efficiency improvements. Also, some government initiatives (e.g. the Australian renewable energy credit scheme) do not currently recognise solar thermal installations as home alternative energy generation.
The cost of an energy source varies considerably. It depends upon how much energy you want, as well as the type of energy generation you want; solar power and diesel power have different costs, for example.
Outsourcing
It is the operation of generation facilities to produce energy at the lowest cost to reliably supply power to customers, recognizing operational restrictions of generation and transmission facilities.
whether its renewable form of energy or not governmental support for the energy generation residual management for energy production
The operation of generation facilities to produce energy at the lowest cost to reliably serve consumers, recognizing any operational limits of generation and transmission facilities
By its self it does not reduce carbon emissions. What it does do is provide an alternative source of energy that does not create any more carbon emissions. Though, this will only become effective when solar energy is more cost effective than carbon based energy.
no you cant
