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.
Are there answer choices or do you just need an answer?
The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
Answer: Carbon Dioxide (CO2)Aerobic organisms (like us!) are organisms that need oxygen. That means they consume oxygen (

)and release carbon dioxide (

).
That
carbon dioxide is the waste product that is taken up by plants during photosynthesis to create more oxygen and sugars (as "food" for the plants). This is seen in the equation for photosynthesis, where the things that are consumed by plants are on the left of the arrow, and the things produced are on the right:

6CO2 + 6H2O + light energy ==> C6H12O6 + 6O2</span>
