If there are less resources on Earth then where are they ?
What is the EROEI of the Universe ?
EROEI Is the ratio of the amount of usable energy acquired from a particular
energy resource to the amount of energy expended to obtain that energy resource.
When the EROEI of a resource is less than or equal to one, that energy source becomes an "energy sink", and can no longer be used as a primary source of energy.
The Energy Density of the Universe
The Universe is made up of 4.9% ordinary matter, 26.8% dark matter and 68.3% dark energy.

Each of these known types of matter are not in a fixed equilibrium they are changing from matter into energy and energy into matter constantly but over varying time periods and so varying durations.
The Effect on Human Evolution.
Humans would only have 5% of the Universe to obtain energy from with there current technology. Humans need to alter the nature of there current technology for obtaining and using energy. Renewables will not be enough if humans intend to leave Earth and explore.
The Search Volume in the Universe needed to get Energy Density.
The whole universe contains about 2.7E+31 cubic light years equivalent to
2.2861775 × 1070 cubic kilometres.
Only 1.1E+57 cubic meters equivalent to 1.1 × 1048 cubic kilometres contains
matter.
1 cubic light year contains about 1E+48 cubic meters equivalent to 1.0 × 1039
cubic kilometres.
Therefore all the matter in the universe would fit into 1 billion cubic light years, or
a cube that's approximately 1,000 light years on each side equivalent to
9.4605284 × 1015 kilometres.
Only 0.0000000000000000000042 percent of the universe contains any matter

The Effect on Human Evolution
The volume humans would have to search is vast.
Enormous energy collectors are going to be needed to get to and extract this
energy.
Humans need to find a completely new energy system beyond there current
technology.
How much Energy Density could be found
Take the density of dark energy and multiply it by the volume of one light-year.
The density of dark energy is 6.9x10-27 kilograms per cubic metre
A cubic light-year is = 8.47x1047 cubic metres.
Therefore, the mass-equivalent of dark energy in a cubic light year is
M = (6.9x10-27 kg per cubic metre) x (8.47x1047 cubic metres)
M = 5.9x1021 kg
To find the energy, use E = Mc2

lightyear-of-empty-space/
E = 5.9x1021 x 89,875,517,873,681,800 m2/s2
E = 5.3026556e+38 j / kg / m 2/ s 2
E = 6.789051131e-30 grams / kWh / m2 / s2
The Final EROEI
EROEI of Universe
= Usable Acquired Energy / Energy Expended
= 5% / 100% = 0.05%
= 6.789051131e-30 / 6.7890511e-30
= 1

Conclusion
Therefore the Universe is an infinite energy sink and can no longer be used as a primary energy source.
Human technology is based on producing huge amounts of energy from matter and matter from energy in the shortest possible time and not storing it.
Natural energy is produced from matter and produces matter from energy over time periods beyond human lifespans in small amounts.
Humans have to totally re-evaluate their understanding and use of finite energy.
They must create technology to extract, produce, use and then recreate minimal energy resources into matter and back into energy.
