What are the 3 sources of energy for the body?
Humans obtain energy from three classes of fuel molecules: carbohydrates, lipids, and proteins. The potential chemical energy of these molecules is transformed into other forms, such as thermal, kinetic, and other chemical forms.

What is a good sources of energy?
A good source of energy fulfils the following criteria:It produces a lot of heat per unit mass.It does a huge amount of work per unit mass.It is easily accessible.It is easy to store and transport.It is economical.It produces less amount of smoke.
What are 2 sources of energy for the Earth system?
The earth is a vast, complex system powered by two sources of energy: an internal source (the decay of radioactive elements in the geosphere, which generates geothermal heat) and an external source (the solar radiation received from the Sun); the vast majority of the energy in the earth system comes from the Sun.
What is meant by a source of energy?
Energy-source definitions A source from which useful energy can be extracted or recovered either directly or by means of a conversion or transformation process (e.g. solid fuels, liquid fuels, solar energy, biomass, etc.)
What is the cleanest source of energy?
Nuclear energyFacts: Nuclear energy is one of the cleanest sources of energy in the United States, emitting no greenhouse gases when generating electricity. It’s our only carbon-free energy source that operates around the clock for 18 to 24 months at a time. Nuclear power plants don’t burn anything.
What is a natural source of energy?
Coal, natural gas, and petroleum formed over thousands of years from the buried remains of ancient sea plants and animals that lived millions of years ago. That is why we also call those energy sources fossil fuels.
What is the cheapest energy source?
solar PV“For projects with low-cost financing that tap high-quality resources, solar PV is now the cheapest source of electricity in history.”
What are the 10 sources of energy?

What is the safest form of energy?
NuclearNuclear is the safest source of energy, producing only one-quarter the number of deaths per terrawatt hour as wind, which is the second safest. Coal is by far the most dangerous, producing deaths both in the mining and transportation and in its emissions of air pollution.
What is the most important source of energy?
the sunOne of the most important sources of energy is the sun. The energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun, and sunlight can also be used to produce electricity from solar (photovoltaic) cells.
What is the biggest natural source of energy?
In 2018, coal is still being used to generate roughly 38% of the world’s total electricity, followed by natural gas with a 23% share.
What are the two main sources of energy?
At the most foundational level, however, there are just two sources of energy. Two sources provide more than 99 percent of the power for our civilization: solar and nuclear. Every other significant energy source is a form of one of these two. Most are forms of solar.
