Why geothermal energy is unlikely to become a main energy source?

Areas that are not geologically active do not produce enough energy to meet our needs.


What is the source for short-term energy needs?

Simple carbohydrates provide the body with short-term bursts of energy.


Is fuel needed to get geothermal energy?

Geothermal energy, such as hot springs, is used to heat home and factories so in this sense geothermal energy is fuel. However to create a system that uses geothermal needs an infrastucture which needs to be designed and built, in this sense geothermal energy needs an energy input.


What compounds do plants make as they grow?

Biomass is a term used to measure the amount of energy in a biotic substance. Biomass is the energy that could be harvested from that plant. The plant itself doesn't produce biomass. Plants do produce O2 as a by-product of respiration, photosynthesis. Plants also produce various carbohydrates which are used by the plant to provide energy needs of the plant and nutrients necessary for the plants growth and ongoing processes.


What happens when ADP gains a phosphate to form ATP?

ATP or adenosine triphosphate. When ADP, adenosine diphosphate, gets a third phosphate group, it becomes ATP. ATP is the energy source of many reactions in the cell. When a reaction needs energy to occur, the enzyme that catalyzes the reaction also cleaves a molecule of ATP into ADP and phosphate. The energy of the phosphate bond is used to fuel the endothermic reaction. The ATP is regenerated (phosphorylation of ADP) in the glycolysis or another process that generates energy.
