A Quote by John Michael Greer
EROEI [energy returned on energy invested, or net energy] is to a civilization what gross profit is to a business, the source of the surplus that supports the entire enterprise.

Surveying the available alternative energy sources for criteria such as energy density, environmental impacts, reliance on depleting raw materials, intermittency versus constancy of supply, and the percentage of energy returned on the energy invested in energy production, none currently appears capable of perpetuating this kind of society.
Energy is gained by giving energy. When we give energy, we gain energy. This is different than having someone manipulate you and take your energy.
We are proposing buildings that, like trees, are net energy exporters, produce more energy than they consume, accrue and store solar energy, and purify their own waste, water and release it slowly in a purer form.
We've got to control our own energy. Now, not only oil and natural gas, which we've been investing in; but also, we've got to make sure we're building the energy source of the future, not just thinking about next year, but ten years from now, 20 years from now. That's why we've invested in solar and wind and biofuels, energy efficient cars.
Everything is energy. All matter is energy. Energy cannot be created or destroyed. It is the cause and affect of itself. It is evenly present in all places, at all times. Energy is in constant motion and never rests. It is forever moving from one form to another. Energy follows thought.
The energy of the stars becomes us. We become the energy of the stars. Stardust and spirit unite and we begin: one with the universe, whole and holy. From one source, endless creative energy, bursting forth, kinetic, elemental; we, the earth, air, water and fire-source of nearly fifteen billion years of cosmic spiraling.
A pound invested in energy efficiency buys seven times more energy solution than a pound invested in nuclear power.
To me, God is an intelligent, loving, conscious energy and why do I say that? Well you need energy to create. You have to have a source. It's undifferentiated energy which has intelligence or it couldn't create.
In nature the only source of energy is from the sun. So in ecological systems everything comes from the sun through the process of photosynthesis whereas now in human built environment our source of energy is from fossil fuels, renewable, wood energy or hydro-energy but it is not from the sun. So until we are able to operate and run a human built environment by imitating photosynthesis it will be a long while before we can have a true eco-system.
Power is not something we should be afraid of. Power is great, power is energy. And in terms of energy, the most important energy is human spiritual energy and when I say spiritual, I feel like have to be very careful, I don't mean religious, I mean the energy of the mind, the energy that exists within us.
The sensitive plate, the gas which is ionised, the fluorescent screen, are in reality receivers, into another kind of energy, chemical energy, ionic energy... luminous energy.
The sun is the source of all energy on planet Earth and we cannot experiment with our only energy source.
All the energy in the universe is evenly present in all places at the same time. We don't get energy, we release energy. And the triggering mechanism to release energy is desire. When you have a strong desire to do something, you will always have the energy to do it.
I expect an energy bill to increase and diversify supply and stabilize energy prices - not drive up energy costs in one part of the country to subsidize energy in another region.
In speaking of the Energy of the field, however, I wish to be understood literally. All energy is the same as mechanical energy, whether it exists in the form of motion or in that of elasticity, or in any other form. The energy in electromagnetic phenomena is mechanical energy.
So long as oil is used as a source of energy, when
the energy cost of recovering a barrel of oil becomes
greater than the energy content of the oil, production
will cease no matter what the monetary price may
be.
