India’s new Minister of Environment and Forests, in the New York Times:
The minister, Prakash Javadekar, said in an interview that his government’s first priority was to alleviate poverty and improve the nation’s economy, which he said would necessarily involve an increase in emissions through new coal-powered electricity and transportation. He placed responsibility for what scientists call a coming climate crisis on the United States, the world’s largest historic greenhouse gas polluter, and dismissed the idea that India would make cuts to carbon emissions.
“What cuts?” Mr. Javadekar said. “That’s for more developed countries. The moral principle of historic responsibility cannot be washed away.” Mr. Javadekar was referring to an argument frequently made by developing economies — that developed economies, chiefly the United States, which spent the last century building their economies while pumping warming emissions into the atmosphere — bear the greatest responsibility for cutting pollution.
Not great news. Vox has interesting coverage of this story, as well; the bottom of their story has a great collection of links.
John Michael Greer, communicating articulately about perturbations to complex systems (read: climate) at The Archdruid Report:
The next time you fill a bathtub, once you’ve turned off the tap, wait until the water is still. Slip your hand into the water, slowly and gently, so that you make as little disturbance in the water as possible. Then move your hand through the water about as fast as a snail moves, and watch and feel how the water adapts to the movement, flowing gently around your hand. .
Once you’ve gotten a clear sense of that, gradually increase the speed with which your hand is moving. After you pass a certain threshold of speed, the movements of the water will take the form of visible waves—a bow wave in front of your hand, a wake behind it in which water rises and falls rhythmically, and wave patterns extending out to the edges of the tub. The faster you move your hand, the larger the waves become, and the more visible the interference patterns as they collide with one another.
Keep on increasing the speed of your hand. You’ll pass a second threshold, and the rhythm of the waves will disintegrate into turbulence: the water will churn, splash, and spray around your hand, and chaotic surges of water will lurch up and down the sides of the tub. If you keep it up, you can get a fair fraction of the bathwater on your bathroom floor, but this isn’t required for the experiment! Once you’ve got a good sense of the difference between the turbulence above the second threshold and the oscillations below it, take your hand out of the water, and watch what happens: the turbulence subsides into wave patterns, the waves shrink, and finally—after some minutes—you have still water again.
This same sequence of responses can be traced in every complex system, governing its response to every kind of disturbance in its surroundings…
… Once things begin to oscillate, veering outside usual conditions in both directions, that’s a sign that the limits to resilience are coming into sight, with the possibility of chaotic variability in the planetary climate as a whole waiting not far beyond that. We can fine-tune the warning signals a good deal by remembering that every system is made up of subsystems, and those of sub-subsystems, and as a general rule of thumb, the smaller the system, the more readily it moves from local adjustment to oscillation to turbulence in response to rising levels of disturbance.
Henry M. Paulson, writing in the NYT:
In a future with more severe storms, deeper droughts, longer fire seasons and rising seas that imperil coastal cities, public funding to pay for adaptations and disaster relief will add significantly to our fiscal deficit and threaten our long-term economic security. So it is perverse that those who want limited government and rail against bailouts would put the economy at risk by ignoring climate change.
This is short-termism. There is a tendency, particularly in government and politics, to avoid focusing on difficult problems until they balloon into crisis. We would be fools to wait for that to happen to our climate.
When you run a company, you want to hand it off in better shape than you found it. In the same way, just as we shouldn’t leave our children or grandchildren with mountains of national debt and unsustainable entitlement programs, we shouldn’t leave them with the economic and environmental costs of climate change. Republicans must not shrink from this issue. Risk management is a conservative principle, as is preserving our natural environment for future generations. We are, after all, the party of Teddy Roosevelt.
Professor Kirk R. Smith, writing at Forbes:
The fracking furor over shale gas is the latest in a series of environmental debates that have bedeviled the oil and gas industry in spite of what might be considered an enviable record compared to related industries, coal for example. From off shore spills to the Keystone Pipeline, the industry probably feels a bit set upon at times. Similarly, its products are often the focus of environmental concern and consequent strict regulation, for example diesel air pollution. Finally, it often bears the brunt of concerns about carbon dioxide emissions leading to climate change risks.
The industry might keep in mind, however, that one of its products, liquefied petroleum gas (LPG — bottled gas containing propane and butane), is actually the most effective solution available for the largest environmental health risk in the world: cooking with solid fuels.
There is some opposition in the environmental community to promoting LPG, a fossil fuel, because of climate concerns. In reality, however, because of the poor combustion typical in biomass stoves, which produces black carbon, methane, and other climate-active pollutants, and the often non-renewable nature of the biomass supplies, which results in CO2 emissions, the net climate impact of a switch to LPG would be negligible. Even if only considering CO2, the incremental impact on global emissions of a switch to LPG would be no more than a percent of the emissions from the developed sector globally. It is not cooking by the poor that poses risk to the climate.
Priceless. More, please.
Well-written and well thought piece on some of the challenges surrounding climate change from Naomi Klein in The Nation:
Another part of what makes climate change so very difficult for us to grasp is that ours is a culture of the perpetual present, one that deliberately severs itself from the past that created us as well as the future we are shaping with our actions. Climate change is about how what we did generations in the past will inescapably affect not just the present, but generations in the future. These time frames are a language that has become foreign to most of us.
This is not about passing individual judgment, nor about berating ourselves for our shallowness or rootlessness. Rather, it is about recognizing that we are products of an industrial project, one intimately, historically linked to fossil fuels.
And just as we have changed before, we can change again. After listening to the great farmer-poet Wendell Berry deliver a lecture on how we each have a duty to love our “homeplace” more than any other, I asked him if he had any advice for rootless people like me and my friends, who live in our computers and always seem to be shopping for a home. “Stop somewhere,” he replied. “And begin the thousand-year-long process of knowing that place.”
That’s good advice on lots of levels. Because in order to win this fight of our lives, we all need a place to stand.
Powerful opinion piece by Michael E. Mann in the NYT:
If scientists choose not to engage in the public debate, we leave a vacuum that will be filled by those whose agenda is one of short-term self-interest. There is a great cost to society if scientists fail to participate in the larger conversation — if we do not do all we can to ensure that the policy debate is informed by an honest assessment of the risks. In fact, it would be an abrogation of our responsibility to society if we remained quiet in the face of such a grave threat.
This is hardly a radical position. Our Department of Homeland Security has urged citizens to report anything dangerous they witness: “If you see something, say something.” We scientists are citizens, too, and, in climate change, we see a clear and present danger. The public is beginning to see the danger, too — Midwestern farmers struggling with drought, more damaging wildfires out West, and withering record summer heat across the country — while wondering about possible linkages between rapid Arctic warming and strange weather patterns, like the recent outbreak of Arctic air across much of the United States.
How will history judge us if we watch the threat unfold before our eyes, but fail to communicate the urgency of acting to avert potential disaster? How would I explain to the future children of my 8-year-old daughter that their grandfather saw the threat, but didn’t speak up in time?
Those are the stakes.
A good interview with Naomi Klein leading her new book coming out in 2014. Read the whole thing here.
You’ve said that progressives’ narratives are insufficient. What would be an alternative narrative to turn this situation around?
Well, I think the narrative that got us into this - that’s part of the reason why you have climate change denialism being such as powerful force in North America and in Australia - is really tied to the frontier mentality. It’s really tied to the idea of there always being more. We live on lands that were supposedly innocent, “discovered” lands where nature was so abundant. You could not imagine depletion ever. These are foundational myths.
And so I’ve taken a huge amount of hope from the emergence of the Idle No More movement, because of what I see as a tremendous generosity of spirit from Indigenous leadership right now to educate us in another narrative. I just did a panel with Idle No More and I was the only non-Native speaker at this event, and the other Native speakers were all saying we want to play this leadership role. It’s actually taken a long time to get to that point. There’s been so much abuse heaped upon these communities, and so much rightful anger at the people who stole their lands. This is the first time that I’ve seen this openness, open willingness that we have something to bring, we want to lead, we want to model another way which relates to the land. So that’s where I am getting a lot of hope right now.
The impacts of Idle No More are really not understood. My husband is making a documentary that goes with this book, and he’s directing it right now in Montana, and we’ve been doing a lot of filming on the northern Cheyenne reservation because there’s a huge, huge coal deposit that they’ve been debating for a lot of years - whether or not to dig out this coal. And it was really looking like they were going to dig it up. It goes against their prophecies, and it’s just very painful. Now there’s just this new generation of young people on that reserve who are determined to leave that coal in the ground, and are training themselves to do solar and wind, and they all talk about Idle No More. I think there’s something very powerful going on. In Canada it’s a very big deal. It’s very big deal in all of North America, because of the huge amount of untapped energy, fossil fuel energy, that is on Indigenous land. That goes for Arctic oil. It certainly goes for the tar sands. It goes for where they want to lay those pipelines. It goes for where the natural gas is. It goes for where the major coal deposits are in the US. I think in Canada we take Indigenous rights more seriously than in the US. I hope that will change.
Devastating. KPCC has an interesting, interactive tool for monitoring California’s wildfires. A bit is embedded below, but the whole thing is worth a look.
NASA’s posted a number of photos of the fire from space. A smattering are embedded below.
In some of the photos, you can see the plume from the Rim Fire and the plume from the American Fire in Tahoe National Forest.
Reno’s been adversely affected by the plume from the Rim Fire, reporting unhealthy on their AQI (can’t find any numbers, at the moment); NASA projects that the plume is impacting AQ in 4 states.
Good luck to the firefighters and rangers working to control the blaze. Our thoughts are with them and others in the surrounding communities.
U.S. Energy Information Administration:
The world’s consumption of gasoline, diesel fuel, jet fuel, heating oil, and other petroleum products reached a record high of 88.9 million barrels per day (bbl/d) in 2012, as declining consumption in North America and Europe was more than outpaced by growth in Asia and other regions (see animated map). A previous article examined regional trends in petroleum consumption between 1980 and 2010; today’s article extends that analysis through 2012.
Some other specific points of interest:
Between 2008 and 2012, Asia’s consumption increased by 4.4 million bbl/d. The rapidly industrializing economies of China and India fueled much of Asia’s demand increase, growing 2.8 million bbl/d and 800,000 bbl/d, respectively. If China’s use of petroleum continues to grow as projected, it is expected to replace the United States as the world’s largest net oil importer this fall.
Petroleum use in Europe has declined in every year since 2006. Part of this decline was related to a reduction in overall energy intensity and government policies that encourage energy efficiency. Europe’s weak economic performance has also affected its petroleum use, with declines of 780,000 bbl/d in 2009 and 570,000 bbl/d in 2012 occurring at a time of slow growth and/or recessions in many European countries.
Past EPA Administrators: The US "must move now on substantive steps to curb climate change, at home and internationally." →
Writing in an NYT Editorial, four previous EPA administrators make a strong case for climate action now.
Climate change puts all our progress and our successes at risk. If we could articulate one framework for successful governance, perhaps it should be this: When confronted by a problem, deal with it. Look at the facts, cut through the extraneous, devise a workable solution and get it done.
We can have both a strong economy and a livable climate. All parties know that we need both. The rest of the discussion is either detail, which we can resolve, or purposeful delay, which we should not tolerate.
Mr. Obama’s plan is just a start. More will be required. But we must continue efforts to reduce the climate-altering pollutants that threaten our planet. The only uncertainty about our warming world is how bad the changes will get, and how soon. What is most clear is that there is no time to waste.
The writers are former administrators of the Environmental Protection Agency: William D. Ruckelshaus, from its founding in 1970 to 1973, and again from 1983 to 1985; Lee M. Thomas, from 1985 to 1989; William K. Reilly, from 1989 to 1993; and Christine Todd Whitman, from 2001 to 2003.
EIA’s recently released International Energy Outlook 2013 (IEO2013) projects that world energy consumption will grow by 56% between 2010 and 2040, from 524 quadrillion British thermal units (Btu) to 820 quadrillion Btu. Most of this growth will come from non-OECD (non-Organization for Economic Cooperation and Development) countries, where demand is driven by strong economic growth.
Renewable energy and nuclear power are the world’s fastest-growing energy sources, each increasing 2.5% per year. However, fossil fuels continue to supply nearly 80% of world energy use through 2040. Natural gas is the fastest-growing fossil fuel, as global supplies of tight gas, shale gas, and coalbed methane increase.
The industrial sector continues to account for the largest share of delivered energy consumption and is projected to consume more than half of global delivered energy in 2040. Based on current policies and regulations governing fossil fuel use, global energy-related carbon dioxide emissions are projected to rise to 45 billion metric tons in 2040, a 46% increase from 2010. Economic growth in developing nations, fueled by a continued reliance on fossil fuels, accounts for most of the emissions increases.
From the report:
We have prepared this Report mindful of the overwhelming scientific consensus about anthropogenic climate change and its worsening impacts, as well as the urgent need to intensify global efforts to combat climate change. Rising temperatures are predicted to lead to sea level rise that could affect tens of millions of people around the world, as well as more frequent and intense heat waves, intensified urban smog, and droughts and floods in our most productive agricultural regions. Global climate change represents a grave threat to the economic livelihood and security of all nations, but it also represents a significant opportunity for sustainable development that will benefit both current and future generations. We believe that ambitious domestic action by China and the United States is more critical than ever. China has given high priority to building an “Ecological Civilization” by striving for green, circular and low-carbon development. It has adopted proactive policies and measures to mitigate and adapt to climate change. The United States is implementing robust policies to promote renewable energy, enhance energy efficiency, and reduce emissions from transportation, buildings, and the power sector. Both countries recognize the need to work together to continue and build on these important efforts.
Five key areas of collaboration were outlined.
- Emission reductions from heavy-duty and other vehicles.
- Smart Grids
- Carbon capture, utilization, and storage.
- Collecting and managing greenhouse gas emissions data.
- Energy efficiency in buildings and industry.
There’s an explicit acknowledgement of coal as a bad actor here, but nothing explicated about moving from dirty to clean fuels for generation of electricity. Some mentions of co-benefits, as well.
Justin Gillis, writing in the NYT about Obama's choice to use the word divest:
He knows that if he is to get serious climate policies on the books before his term ends in 2017, he needs a mass political movement pushing for stronger action. No broad movement has materialized in the United States; 350.org and its student activists are the closest thing so far, which may be why Mr. Obama gazes fondly in their direction.
�I�m going to need all of you to educate your classmates, your colleagues, your parents, your friends,� he said plaintively at Georgetown. �What we need in this fight are citizens who will stand up, and speak up, and compel us to do what this moment demands.�
Let's hope the movement towards divestment grows.
Details on 'Power Africa,' the White House's new plan for electrification across sub-Saharan Africa →
From the White House:
Today the President announced Power Africa, a new initiative to double access to power in sub-Saharan Africa. More than two-thirds of the population of sub-Saharan Africa is without electricity, and more than 85 percent of those living in rural areas lack access. Power Africa will build on Africa’s enormous power potential, including new discoveries of vast reserves of oil and gas, and the potential to develop clean geothermal, hydro, wind and solar energy. It will help countries develop newly-discovered resources responsibly, build out power generation and transmission, and expand the reach of mini-grid and off-grid solutions.
According to the International Energy Agency, sub-Saharan Africa will require more than $300 billion in investment to achieve universal electricity access by 2030. Only with greater private sector investment can the promise of Power Africa be realized. With an initial set of six partner countries in its first phase, Power Africa will add more than 10,000 megawatts of cleaner, more efficient electricity generation capacity. It will increase electricity access by at least 20 million new households and commercial entities with on-grid, mini-grid, and off-grid solutions. And it will enhance energy resource management capabilities, allowing partner countries to meet their critical energy needs and achieve greater energy security.
As that first paragraph points out, this is inherently an issue of rural energy — and of household energy. The following bit seems a bit… optimistic:
Power Africa will work in collaboration with partner countries to ensure the path forward on oil and gas development maximizes the benefits to the people of Africa, while also ensuring that development proceeds in a timely, financially sound, inclusive, transparent and environmentally sustainable manner.
Allowing the Keystone pipeline to be built requires a finding that doing so would be in our nation’s interest. And our national interest will be served only if this project does not significantly exacerbate the problem of carbon pollution. The net effects of the pipeline’s impact on our climate will be absolutely critical to determining whether this project is allowed to go forward. It’s relevant.
The EPA, reviewing the State Department’s environmental impact assessment of the Keyspan proposal:
As recognized by the DSEIS (Department of State’s draft Supplemental Environmental Impact Statement), oil sands crude is significantly more GHG intensive than other crudes, and therefore has potentially large climate impacts. The DSEIS reports that lifecycle GHG emissions from oil sands crude could be 81% greater than emissions from the average crude reformed in the U.S. in 2005 on a well-to-tank basis, and 17% greater on a well-to-wheels basis. This difference may be even greater depending on the assumptions made. The incremental emissions from oil sands crude transported by the Project would therefore be 18.7 million metric tons C02-e (carbon dioxide equivalent) per year when compared to an equal amount of U.S. average crudes, based on the Project’s full capacity of 830,000 barrels of oil sands crude per day. To place this difference in context, we recommend using monetized estimates of the social cost of the GHG emissions from a barrel of oil sands crude compared to average U.S. crude. If GHG intensity of oil sands crude is not reduced, over a 50 year period the additional C02-e from oil sands crude transported by the pipeline could be as much as 935 million metric tons.
The whole report is interesting, though laden with acronyms. The EPA decided that there’s insufficient information to make a clear decision at this point, tossing the ball back into State’s court. They specifically focus on a central conclusion of the DSEIS report — that the tar sands oil will find a way to market whether or not the pipeline is built. EPA doesn’t contest that point directly, but requires more sophisticated and modern modeling of the impacts of these alternates routes of getting the oil to the US. This makes sense — if the oil will be pulled from the ground and travel to and through the US, then all possible routes and methods of transport must be equally evaluated.
That said, the current analysis of Keystone indicates it could “significantly exacerbate the problem of carbon pollution.”
Obama: "...that bright blue ball rising over the moon's surface, containing everything we hold dear -- the laughter of children, a quiet sunset, all the hopes and dreams of posterity -- that's what's at stake." →
President Obama, yesterday at Georgetown, at the end of his speech calling for action and outlining new policies on climate change:
Understand this is not just a job for politicians. So I’m going to need all of you to educate your classmates, your colleagues, your parents, your friends. Tell them what’s at stake. Speak up at town halls, church groups, PTA meetings. Push back on misinformation. Speak up for the facts. Broaden the circle of those who are willing to stand up for our future.
Convince those in power to reduce our carbon pollution. Push your own communities to adopt smarter practices. Invest. Divest. Remind folks there’s no contradiction between a sound environment and strong economic growth. And remind everyone who represents you at every level of government that sheltering future generations against the ravages of climate change is a prerequisite for your vote. Make yourself heard on this issue.
I understand the politics will be tough. The challenge we must accept will not reward us with a clear moment of victory. There’s no gathering army to defeat. There’s no peace treaty to sign. When President Kennedy said we’d go to the moon within the decade, we knew we’d build a spaceship and we’d meet the goal. Our progress here will be measured differently — in crises averted, in a planet preserved. But can we imagine a more worthy goal? For while we may not live to see the full realization of our ambition, we will have the satisfaction of knowing that the world we leave to our children will be better off for what we did.
“It makes you realize,” that astronaut said all those years ago, “just what you have back there on Earth.” And that image in the photograph, that bright blue ball rising over the moon’s surface, containing everything we hold dear — the laughter of children, a quiet sunset, all the hopes and dreams of posterity — that’s what’s at stake. That’s what we’re fighting for. And if we remember that, I’m absolutely sure we’ll succeed.
Mother Jones’s nice outline of the key points of the speech follows:
Here are the key components of the plan aimed at reducing US emissions:
Directs the EPA to issue draft emission rules for existing power plants by June 2014, to be finalized by June 2015.
Asks the EPA to “work expeditiously” on finalizing rules for new power plants that the agency issued in March 2012 (though does not appear to include a due date for that).
Pledges that the federal government will draw 20 percent of its power from renewable sources by 2020.
Sets a goal of permitting an additional 10 gigawatts of renewable energy on public lands by 2020.
Sets a goal of putting 100 megawatts of renewable energy on federally subsidized housing by 2020.
Creates a new, $8 billion loan guarantee program for advanced fossil fuel projects at the Department of Energy (think clean coal, etc.).
Directs the EPA and the Department of Transportation to work on fuel economy standard for heavy-duty trucks, buses, and vans for after 2018 (following up on the 2014-18 rules they rolled out in 2011).
Sets a goal of cutting at least 3 billion tons of carbon pollution by 2030 through improvements in energy efficiency standards.
Calls for an end to US funding for fossil fuel energy projects overseas unless they include carbon capture technology.
The SCC estimates using the updated versions of the models are higher than those reported in the 2010 TSD. By way of comparison, the four 2020 SCC estimates reported in the 2010 TSD were $7, $26, $42 and $81 (2007$). The corresponding four updated SCC estimates for 2020 are $12, $43, $65, and $129 (2007$). The model updates that are relevant to the SCC estimates include: an explicit representation of sea level rise damages in the DICE and PAGE models; updated adaptation assumptions, revisions to ensure damages are constrained by GDP, updated regional scaling of damages, and a revised treatment of potentially abrupt shifts in climate damages in the PAGE model; an updated carbon cycle in the DICE model; and updated damage functions for sea level rise impacts, the agricultural sector, and reduced space heating requirements, as well as changes to the transient response of temperature to the buildup of GHG concentrations and the inclusion of indirect effects of methane emissions in the FUND model. The SCC estimates vary by year, and the following table summarizes the revised SCC estimates from 2010 through 2050.
After reviewing the full document, the changes update the science to the state of current understanding. As such, the projections offered within are more current (and based on more evolved science) than previously SCC estimates. The conclusions from the report are significant, but seem to overplay the US’s actions and role to date:
However, the climate change problem is highly unusual in at least two respects. First, it involves a global externality: emissions of most greenhouse gases contribute to damages around the world even when they are emitted in the United States. Consequently, to address the global nature of the problem, the SCC must incorporate the full (global) damages caused by GHG emissions. Second, climate change presents a problem that the United States alone cannot solve. Even if the United States were to reduce its greenhouse gas emissions to zero, that step would be far from enough to avoid substantial climate change. Other countries would also need to take action to reduce emissions if significant changes in the global climate are to be avoided. Emphasizing the need for a global solution to a global problem, the United States has been actively involved in seeking international agreements to reduce emissions and in encouraging other nations, including emerging major economies, to take significant steps to reduce emissions.
This is a step in the right direction, but dodges real leadership.
From Our State magazine, a well-written piece about idyllic Bald Head Island. Sounds pretty nice:
Toward the ends of many afternoons, they all came together, usually gathering on East Beach, for what they took to calling TPP, or Total Population Parties. The kids’ job was to collect a mess of driftwood to make a fire. The women brought hush puppies and coleslaw. The men cooked the fish they caught that day or boiled a big pot of shrimp or made chowder from fresh clams. They ate and told stories and jokes. They played guitar and sang songs. They even shared some coveted “diamonds” for drinks.
The sun set.
Out came the ghost crabs skittering on the sand and the bright white stars in the sky.
At the Dunlaps’ by the beach, where they almost never ran their generator for light, the adults lit the lanterns, probably a dozen or so latched to the walls, 6 or 7 feet off the floor. They played Monopoly or dominoes or checkers or chess. The kids ran up and down the beach, around on the dunes, just enough light from the moon. They clambered up a ladder to the wide, flat deck on the roof of the house. From there, they could see the hulking cargo ships, with their blinking lights, coming in off the Atlantic and approaching the mouth of the river. They went back down in the house and grabbed all the cushions, dragged them back up to the deck, and finally closed their eyes.
Seems like the island’s got some advocates worried about climate change, too.
Bald Head Island Conservancy has developed a comprehensive public outreach campaign to help educate community members about the potential impacts of climate change to the island and individual choices that can help improve the socioecological system’s resilience. Staff work with community members to identify tangible solutions to future problems. The Conservancy has attained funding to build a research and educational facility and is developing a knowledge sharing network, the Coastal Barrier Island Network, with other barrier islands to facilitate the transfer of knowledge and lessons learned as communities begin to adapt to climate change.
Paul Gipe: "For the Amount Spent on the Iraq War the US Could be Generating 40% to 60% of its Electricity with Renewable Energy" →
If we had invested the $3.9 trillion that the war in Iraq will ultimately cost, we would generate nearly 40% of our electricity with new renewables. Combined with the 10% of supply from existing hydroelectricity, the US could have surpassed 50% of total renewables in supply.
However, this is a conservative estimate. If we include the reasonable assumptions suggested by Robert Freehling, the contribution by renewables would be even greater.
Freehling’s assumptions raise to as much as 60% the nation’s lost potential contribution by new renewables to US electricity supply by going to war in Iraq. With the addition of existing hydroelectric generation, the opportunity to develop as much as 70% of our nation’s electricity with renewable energy was lost.
And unlike the war in Iraq, which is an expense, the development of renewable energy instead of war would have been an investment in infrastructure at home that would have paid dividends to American citizens for decades to come.
