The effects of climate change are all around. They can be seen by the Gulf Coast bracing for seven named storms in 2020; wildfires in California interrupting electricity for hundreds of thousands; and winter storms leaving millions without power. The changes I recommend will help solve problems that the military has been partially responsible for creating.

As a 16-year naval aviator, I have seen how serious climate instability is: From the flooding of our naval bases, due to the rising sea level, to increased storms at a higher intensity, the climate emergency is affecting our military’s capability to operate. During my service, I had to cancel missions due to hurricanes, typhoons and other severe weather.

The military is currently trying to adapt to the instability it is partially responsible for. The Department of Defense consumes more energy than any other organization in the U.S., most of which is dirty energy. It maintains over 500,000 buildings, the majority of which are more than 50 years old, and uses about 70 million gallons of automotive fuel for nontactical vehicles per year. This is enough to drive around the Earth 141 times.

But there is something we can do.

This is a time in history where the Biden administration, through the military, can make a definitive change in the way the country produces energy, and begin to address the climate crisis.

President Joe Biden promised to “Build Back Better,” creating American jobs in the green energy sector, improving building standards and generating new green innovation. This ambitious and necessary plan has another avenue to stimulate the new green economy and address the climate crisis that wouldn’t require congressional squabbling. With one executive order, President Biden could green the military and jump-start the process.

As of 2014, two of the top 10 solar panel producers are in the United States; of the others, six reside in China. How can the president jump-start the new economy and create American jobs in the process? By investing $8 billion in renewable energy for the DoD. This will save money, provide energy security, greatly reduce its carbon footprint and create thousands of jobs.

In 2017, the DoD spent $3.57 billion on energy for noncombat operations. Installing solar panels on DoD buildings and adding small wind turbines to half of military buildings would cost $8 billion, but it would provide enough energy to power the equivalent of 750,000 homes.

Changing the military’s noncombat vehicles to electric would encourage electric vehicle-manufacturing facilities to open in the U.S., save $170 million per year and prevent 702,000 tons of carbon injected into the atmosphere.

This investment would directly purchase 13.2 million solar panels, 150,000 wind turbines and thousands of electric vehicles — all manufactured and installed in the U.S. by Americans. It would create lasting jobs and companies within our borders. The $8 billion would pay for itself in less than three years from the savings gained through renewable energy to the military.

More than 50 percent of the energy used in U.S. homes in 2015 was used for heating and cooling. President Biden has pledged to reduce the carbon footprint of U.S. buildings. Passive house standards reduce heating and cooling costs by 90. Requiring new military construction to be built to this standard and retrofitting older buildings would greatly reduce their carbon footprint.

Microgrids — or small networks of electricity users with a local source of supply — are the future of electricity. But research into microgrids has not happened at the necessary pace. Military facilities with installed renewables are the perfect place to test this new technology through a public-private venture. The information gained can be applied to cities and the entire country.

The future of the electric grid will be composed of renewable energy and passive storage devices routed through interconnected smart grids. This will provide a green, reliable, resilient electrical system. The U.S. must be the leader in this green innovation. Without the U.S. setting the future green standards, jobs and new technology will go to other countries.

With one stroke of his pen, President Biden can provide support and leadership our nation needs to rise to the challenge and seize these opportunities. An executive order on federal agency leadership for clean energy, efficiency, electrification, climate resilience and energy security can start with the DoD and extend throughout the nation. Doing so will make our country and military stronger, create American jobs and save money.

Prioritize NATO’s core task: collective defense
The risk of conflict by miscalculation or by escalation of an incident is greater today than at any time since the end of the Cold War. NATO’s deterrent posture needs to be strengthened in both the Baltic and Black Sea area to reduce this risk.

For JADC2, the Pentagon should learn from the 5G community
The Department of Defense should take a lesson from the 5G community. Rather than spending years of committee work trying to reach consensus on exactly how JADC2 should be constructed, it should move out on delivering working joint capabilities from existing systems for key combatant command needs.
