Congress can take action to reduce greenhouse gas emissions and support the transition to clean energy. One approach is to extend and expand tax credits for renewable energy and battery storage that have helped drive investments in clean energy and begun decarbonizing our electricity sector. This action was aimed at a 2019 proposal to exapand clean energy tax credits.


The single most powerful way to fight climate change, and what you can do to support it

Probably the number one question people ask when they learn I’m a climate solutions advocate is, What is the most important thing I can do? It’s a difficult question, because there is no single solution to the climate crisis. We know that individuals alone cannot solve this, and that we need big, ambitious government action soon for any chance of containing climate change to adaptable levels. So where should governments start, and how can you help?

There’s actually a simple answer. We need a price on carbon. This is the overwhelming consensus from UN climate experts, 27 Nobel laureates and 3500 of the U.S.’s top economists, political leaders including Bernie Sanders, Barack Obama, James Baker, George Schultz, EPA chiefs under 4 Republican presidents, leading climate scientists Michael Mann, James Hansen, and Katherine Hayhoe, a growing number of business leaders, and most recently the IMF. Increasingly, experts also agree that a good way to do this is with carbon fee and dividend, collecting a rising fee from polluters and giving the money back to households to protect low- and middle-income families through a clean energy transition.

And today, even as this administration tries to dismantle every bit of climate progress we’ve made, we are closer than ever before to enacting this key policy solution. Right now, there is a bill in the United States Congress, The Energy Innovation and Carbon Dividend Act (HR 763), to put a rising price on carbon, return all the money as a monthly dividend to households, and enact a border carbon adjustment. This bill, the strongest climate bill introduced into Congress in a decade, would reduce carbon emissions by 40 percent by 2030 and currently has 69 co-sponsors, more than any other major climate policy ever. Learn more about how HR 763 works.

I believe that the most important thing you can do right now for the climate is to work for passage of this bill. Carbon pricing alone will not solve the climate crisis–but without it, solving the climate crisis is unimaginable.

Almost daily, we experience more of the terrible costs and risks of not acting. As I write this, California is again fighting extraordinarily destructive and massive wildfires. Hawaii’s corals are dying from a new ocean heat wave. Some business, religious, and political leaders are speaking out about the need for action, and a global youth climate movement is demanding climate justice for the marginalized and vulnerable around the world who are least responsible for this crisis and are suffering most. And the IMF, tasked with keeping the global economy functioning, has just urged countries to enact a substantial carbon price. Canada has passed a national carbon tax, and we in the U.S. now have a good bill, which has led to a flurry of other bills being introduced.

So if you want to do something that matters, ask your members of Congress to co-sponsor, support, and pass this bill. (Citizens’ Climate Lobby has made it easy to email or write your members of Congressin support of this bill). I believe a groundswell of support from individual voters is needed to overcome the powerful forces fighting climate action. Push Congress to pass this bill, so that it can be signed into law on the first day we have a president who accepts the facts and values protecting a livable world. Let’s be sure that’s January 1, 2021, at the very latest.

Corvallis High School student strikers

The kids are not all right: The student climate strikes, Greta Thunberg’s message and where to go from here

What a week it’s been! On September 20th, I went to the Corvallis school climate strike to support high school students as they marched to City Hall to demand action on climate change. It was a first in our town, and the kids were mad. They didn’t care that most of the adults there have been working for climate action for years. They were telling us all that we’ve failed them. And they have a point.

A stunningly-illustrated spread in the September 19th issue of Nature shows the hard truths about climate change: the continued growth of emissions world-wide, the dramatically steep reductions necessary to have a chance of preventing catastrophic climate warming, the billions of people at risk from heat waves, water stress, and other threats, and the largest producer of cumulative emissions (the United States).

On September 25th, the IPCC released a report on threats to the world’s oceans and cryosphere from climate change. The report, written by more than 100 of the world’s leading ocean and climate scientists, states that climate change is warming the oceans and changing their chemistry so dramatically that it is threatening seafood supplies, fueling more destructive cyclones, worsening floods, and threatening hundreds of millions of people who live in coastal areas. Without immediate, steep reductions in greenhouse gas emissions, impacts to the oceans and humanity will soon be world-wide, catastrophic and irreversible.

What a week it’s been! I’m rattled because listening to Greta Thunberg, the student protesters, and the latest scientific assessments, I’ve thought about what has happened in the 13 years since I became truly alarmed about climate change and began down the path to becoming a climate solutions advocate.

The science has advanced. Technological solutions have made giant strides. Public concern has been growing, although not nearly as quickly as the facts demand. Now Greta, the student strikers, and the scientists are stating what I know to be true: we’ve run out of time.

An immediate global transition away from fossil fuel burning and forest destruction, and toward renewable energy, conservation, and sustainable agriculture might allow us to bring emissions down quickly enough to prevent the worst, most catastrophic climate harms, if this transition moves at a breathtaking pace. (For a good simple explanation of the science, see “What does ’12 years to act on climate change’ (now 11 years) really mean?” )

We have the technology and resources to do it, but we haven’t demonstrated the will. We lack the kinds of functioning political systems to make solving climate change seem possible. As David Roberts said way back in 2013, we are caught between the impossible (acting) and the unthinkable (failing to act). To avoid the unthinkable, we have to be all in, everywhere; we have to make the impossible (a rapid and complete transition to a zero carbon emissions world) possible. All of us, governments, businesses, communities, and individuals. That is what Greta, the student strikers, and even now the climate scientists, are begging us to do.

Voting for the climate is absolutely critical. But it’s only the beginning. Creativity, persistence, commitment, imagination, courage, cooperation with people outside your crowd, and unknown other ingredients will all be needed. I’m contemplating how to use my skills and strengths in new ways to heed the call that went out this week. I hope you will watch my website and this blog for ideas and opportunities. And I hope you too are imagining how to step up. We make the path by walking it.

The four things we need to do now for climate action (Thank you, David Roberts!)

Last fall, I did something I thought I would never, ever do: I leased a brand-new car. I had been driving a used all-electric Nissan Leaf, and its 40-mile range just didn’t work for me anymore. So I leased an all-electric Chevy Bolt. Although I’m not crazy about having a car payment, I feel great about this choice; leasing an electric vehicle passed the test I use to decide which climate actions to take and which climate policies to support.

Where did I get this test? David Roberts, who writes about climate change and energy for Vox, gave it to me in his article “What genuine, no bulls**t ambition on climate change would look like.”

In this article, Roberts discusses three publications examining pathways to the 1.5°C target discussed in the Paris Climate Agreement. He finds that all the scenarios agree there are four things we absolutely must do–and do quickly–to have any reasonable chance of containing runaway climate change before its consequences become catastrophic and it threatens human societies around the world.

First, we need to dramatically increase energy efficiency. How efficient we are is measured as “energy intensity,” defined as the amount of energy required to produce a unit of GDP.  In all three scenarios, energy intensity needs to fall quickly and outpace economic growth. In one scenario, energy intensity falls by two thirds by 2050. Polices that raise efficiency standards for buildings, industries, vehicles, and appliances are all effective ways to catalyze this change. So is placing a rising price on carbon emissions.

Second, we need to dramatically increase renewable energy production. All scenarios show renewables—mostly wind and solar—rapidly becoming the dominant sources of electricity. The scenarios range from 85% renewable electricity generation by 2050 to 100% renewable electricity by 2040. Carbon pricing, renewable electricity standard laws, incentivizing renewable energy development, eliminating fossil fuel subsidies, and many other policies can speed up the shift to clean electricity generation.

Third, we need to electrify everything.This is where my all-electric Bolt comes in. All scenarios require electrification of all sectors currently running on fossil fuels.  Once our economy runs on electricity, we have the technology and the infrastructure to run it on clean energy.  Currently, the many issues related to making zero-carbon liquid fuels have not been resolved.

The fourth thing we must do is to sequester carbon, or, as Roberts puts it, pursue negative emissions. Even if we ramp up quickly on global efforts to decarbonize our energy systems, all three scenarios suggest we will also need to remove some carbon dioxide from the atmosphere. Both forests and soils have the potential to store a lot of carbon. Planting trees, allowing forests to regrow, and changing to agricultural practices that enrich soil carbon have the potential to sequester carbon. A variety of interesting proposals and programs have started to find ways to do this. 

David Roberts is my favorite climate journalist.  I don’t always agree with his strong opinions or love his sometimes snarky Twitter feed, but he’s a voracious consumer of key climate information and a fantastic big-picture synthesizer of what it all means. I also think he’s really smart. He helped me to see that assessing climate solutions is pretty simple.  I’m for any solution or policy that contributes in a big way to these four steps—increasing energy efficiency, increasing renewable energy production, electrifying everything, and sequestering carbon—because we know what we must do and we are out of time. 

One clean energy solution you may be underestimating

When I was a kid, my favorite grandfather–a retired businessman and a dreamer–bought us a windmill. We were excited by the idea of wind generating some of our electricity, but that’s not what happened. After a series of delays and mishaps, the assembled structure was a spindly, fragile-looking thing perched on a tall metal lattice structure that from the start failed to produce any significant electricity at my parents’ gusty cliff-side house, an expensive disappointment. 

Forty years later, as I’m traveling through eastern Washington, modern wind turbines dot the wide-open grasslands. Cows grazing on a nearby hillside look very much like tiny black and white ants. It’s tricky to get a sense of the scale of these descendants of my grandfather’s windmill until we turn off on a side road that leads to a pullout near the base of a turbine. The tower is at least 200 feet tall, with three blades that are more than 100 feet long; I’ve read that the energy generated by a single one of today’s turbines can power hundreds and hundreds of homes.

If you don’t live in a windy open landscape, you may be more aware of advances in solar panels than wind turbines. Yet when experts model a successful transition to a clean energy society, wind plays a critical role. Today’s wind energy is cheap, efficient, and capable of supplying lots of electricity across a large swath of the United States and other parts of the world too. It’s also an excellent complement to solar power, often producing power when solar panels are not. Advances in grid technology and unexpectedly rapid declines in battery costs are improving reliability and reducing the cost of installing wind energy projects in the United States and the world. According to a report from the American Wind Energy Association (AWEA) the cost of wind power has dropped 67 percent since 2009, and now Texas, Iowa, Kansas, Oklahoma, and South Dakota all get more than 30 percent of their electricity from wind turbines.

Some experts also suggest that offshore wind farms, still in the early stages of deployment, may become a central clean energy source in the coming years. A 2017 analysis found that open ocean wind farms have the potential to power the entire world.

There is no free lunch, no harmless way to power today’s world. Since the 1990s, we’ve known that wind turbines pose a threat to birds and bats, who sometimes fly into the moving blades and are killed. Although this sad discovery led to some fierce criticism of  wind energy, it’s also led to important efforts to reduce bird deaths, including siting wind farms to minimize bird risk. 

A 2018 article in Audubon magazine summarizes Audubon’s stance on wind energy. After releasing a 2014 report on birds and climate change which found that climate change will threaten more than half of North America’s birds if we don’t rapidly reduce emissions, Audubon has become a powerful advocate for transitioning to renewable energy, including wind. Audubon is therefore working in collaboration with the wind industry on developing best practices for wind farms to minimize harm to birds, and highlighting other technologies being developed to make wind energy safer for wildlife.

I think of my grandfather whenever I see wind turbines across an open landscape. I think he would find today’s wind turbines miraculous and even beautiful in their way. He was a dreamer who was always excited by the promise of new technology; this is one that has a central role to play in a clean-energy powered future.
