Wind power is an alternative to conventional fossil fuels. however, wind power is dependent on variable weather patterns. what is the most important drawback of this dependency? a) the energy output from wind farms is negligible. b) unlike solar energy, wind energy is not renewable. c) wind energy cannot be used to generate electricity. d) a backup energy source is required to make up for shortfalls.

The awnser seems to be d

D). A backup energy source is required to make up all short falls.

Explanation:

Wind is a renewable source of energy as wind can be replenished in nature. It is an alterntive source of energy which reduces some dependency over the use of conventional sources of energy like fossil fuels.

As the weather condition can influence the direction as well as speed of the wind currents . Therefore, it cannot be consider as a reliable source for availing the daily energy needs. Hence, a backup is required to meet the energy needs when no or very few amount of energy could be harnessed by wind power plant.

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.
