solar and wind
The two main sources of energy gas and electricity.
From our closest star: Hydrogen fusion (The Sun) from under our feet: Geothermal heat; geothermal energy originates from the original formation of the planet (20%) and from radioactive decay of minerals (80%)
solar energy and energy from fossil fuels
nuclear energy and burning fossil fuels to push turbines that make electricity. ************************************************* the two main sources are burning lots of fossil fuels and nuclear energy
The two sources of energy are the sun and energy from the Earth's Interior.
The Earth system is powered by energy from two major sources: the Sun and the planet's internal heat.

You can get energy from Carbohydrates, Fat and to a lesser extent protein.
Energy itself will not go away, but major sources of energy for the large-scale needs of the planet will shift. At some point roughly within the next century or two the planet will run out of oil and other fossil fuels. We will learn how to safely develop other sources of energy.

The two types of thermal energy sources are Geothermal and Thermal Energy
there are not just two electrical sources of energy there are lots but two could be solar and biomass
