Which of the following explains why nonrenewable energy resources are still so widely used. select multiple . arenewable energy provides less power in some areas. brenewable energy is more polluting than nonrenewable energy. crenewable energy can be more expensive than nonrenewable energy. drenewable energy sources are not as reliable in terms of power output.

Non renewable resources can be very expensive, especially in capital outlay. For example, wind energy is very expensive to get started. The batteries alone are a headache. What do you do with those batteries whose life is over? How do you dispose of them? It isn't an easy problem to solve.

Then there's the labor part of wind energy. If they are manufactured in Denver Co and they receive an order from Maine, the blades require a wooden plywood box to be made. Plywood is roughly 20$ a 1/2 sheet (in Canada) to say nothing of the carpenter needed to make the box. I'm told that it takes a good day and one half just to make that box alone. That's for 1 blade. Then there's the shipping cost for 3 blades. Then there's the cost of making the blades which require highly skilled workers. 

Then there's the problem of wind, (or lack thereof). the problems just keep on going up and the expenses with them.
