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.
Answer:
sun gives plant energy which gives animal and humans food
Explanation:
The biological macro molecule is CARBOHYDRATE.
Carbohydrates are made up of just three elements, which are carbon, hydrogen and oxygen, all joined together in a ringed structure. The number of carbon a carbohydrate has determined the class of carbohydrate under which it is grouped. The particular one we are given in this question has five carbon, so it is a pentose sugar.
Carbohydrate are the major source of energy in the living cells.

or clear, sunny skies. The biosphere interacts most with this layer. </span>
The stratosphere is the second layer
from Earth's surface. Winds are strong and steady in this layer. <span>

The mesosphere is heated by the ozone
layer beneath it. This layer is where most meteor showers occur.
The
thermosphere contains the ionosphere and exosphere. It contains layers of
single, unmixed gas.
