How Green is Green?Renewable or “Green” Energy and Sustainability
What is “sustainability”?
“The ability to maintain the necessary level and duration of operational activity to achieve military objectives.” (JP 1-02)
…the capacity for continuance into the long term future
Sustainability and the “Triple Bottom Line”:
Mission
Community
Environment

How Green is Green?Renewable or “Green” Energy and Sustainability
Sustainability aspects include: Human activities, interactions and institutions Resource exchange (i.e. flows of energy and materials) Ecosystem manipulation
L.E.S.S. is more: Leave it => limit flows from lithosphere to biosphere Eat it => waste must equal food; there are limits Spare it => maintain biological diversity and productivity Share it => meet basic needs worldwide

How Green is Green?Renewable or “Green” Energy and Sustainability
Three kinds of resources: Natural flows (sunlight, winds, ocean currents, etc.)
…continuously flowing resources, from which society can deflect a flow to meet its needs
Funds (forests, fish populations, etc.) …use natural flows to maintain themselves and when harvested
will regenerate, if not irreversibly damaged
Deposits (natural gas, petroleum, coal, etc.) …have no (or very limited) re-growth possibility within human
planning horizons and are gradually depleted when extracted

How Green is Green?Renewable or “Green” Energy and Sustainability
What is “renewable” energy?
Renewable energy sources are constantly replenished and will never run out. (NREL)
Renewable energy sources come from existing flows of energy, from ongoing natural processes

How Green is Green?Renewable or “Green” Energy and Sustainability
What are the different types of “renewable” energy?* Solar energy Wind energy Biomass energy Geothermal energy Hydroelectric power Hydrogen energy Ocean energy
Does not include fossil fuels or nuclear energy!* Adapted from information found on the NREL website.

How Green is Green?Renewable or “Green” Energy and Sustainability
Solar energy* Photovoltaic (solar cell) systems:
producing electricity directly from sunlight
Concentrating solar systems:
using the sun’s heat to produce electricity
Passive solar hearing and daylighting:
using solar energy to heat and light buildings
Solar hot water:
heating water with solar energy
Solar process heat and space heating and cooling:
industrial and commercial uses of the sun’s heat* Adapted from information found on the NREL website.

How Green is Green?Renewable or “Green” Energy and Sustainability
Wind energy*
Wind turbines
Stand-alone applications (e.g. water pumping or communications)
Connected to a utility power grid (e.g. a wind plant or “farm”)
* Adapted from information found on the NREL website.

How Green is Green?Renewable or “Green” Energy and Sustainability
Biomass energy*
Biofuels:
converting biomass into liquid fuels for transportation
Biopower:
burning biomass directly, or converting it into a gaseous fuel or oil, to generate electricity
Bioproducts:
converting biomass into chemicals for making products typically made from petroleum
* Adapted from information found on the NREL website.

How Green is Green?Renewable or “Green” Energy and Sustainability
Why is renewable energy important? Environmental benefits
Renewable energy technologies have much lower environmental impact than conventional energy technologies
Sustainable supplies Renewable energy sources will not run out, but other sources are
finite and can be depleted
Economic benefits Renewable energy investments are typically local, creating jobs and
fueling local economies rather than contributing to energy imports
Energy security Renewable energy reduces dependency on foreign oil supplies
