According to the Nutrition Facts label on many food products, Fats can supply 9 calories of energy per gram, carbohydrates and proteins have 4 calories per gram. It would therefore make sense to say humans get most of their energy from fats they eat.
However, in the United States, most peoples diet is largely of carbohydrates: breads, cakes, donuts, pasta, etc. Many foods have added sweeteners such as sugar and corn syrup. So the reality is that most peoples diets and energy comes from carbohydrates and what isn't used as energy is converted to and stored in the body as fat.
In food, there are three macronutrients that provide energy. They are fat, carbohydrates, and protein. Fat is the nutrient that provides the greatest amount of energy at nine calories per gram. Protein and carbohydrates provide only four calories per gram.

Wind energy has the potential to supply a significant amount of the world's electricity needs. It is estimated that wind energy could potentially supply more than 20% of global electricity demand by 2030. The amount of energy that can be supplied by wind depends on factors such as geographical location, technology advancements, and investment in wind infrastructure.
yes
Fats supply a number of nutrients to the body. They are the main source of fatty acids and are also synthesized to provide energy to the cell.
the nutrients in the food supply the body with energy
yes.
Plants are the organisms that produce their own food through photosynthesis and supply other organisms in the ecosystem with energy and nutrients. They are the primary producers in most ecosystems.
