A journalist recently quoted me as saying that to address climate change, we should keep fossil fuels in the ground. So far, so good. But he added that we should then invest heavily in renewables like wind, solar, hydropower and even nuclear, as if this was my opinion.
It wasn’t the only part of the article that Justin Catanoso made up, but it is probably the most important to correct.
We didn’t talk about either hydropower or nuclear energy during the 45-minute interview. I’ve asked Catanoso to correct this mistake (and others) in the article, but he has (so far) declined to do so. He seemed more concerned about telling me how long he’d been a journalist (30 years, in case you’re wondering) and told me that in his view, I “come off sounding pretty good” in the article.
Frankly, I couldn’t care less about Catanoso’s views. While I don’t want an argument with him, I do want him to quote me accurately, and avoid giving the appearance that I support to the hydropower and nuclear industries. I don’t support either.
Damming the Mekong River
As I told Catanoso during the interview, in the 1990s I worked for several years with an NGO in Bangkok called TERRA (Towards Ecological Recovery and Regional Alliance). TERRA works on social and environmental issues in the Mekong Region, where dam-building poses an enormous threat to fisheries, farmland, rivers and people’s livelihoods and environments.
In 1995, I visited the area of the then-proposed Yali Falls dam in central Vietnam. Indigenous villagers told me that the government’s consultation process was just propaganda. They didn’t even know whether their village would be flooded. One of them told me a traditional saying to describe how powerless they felt about the dam: “We must eat a bitter fruit and say it is sweet”.
I’ve written a series of articles critiquing the proposed dams and pointing out the impacts of some of the dams that had already been built in the Mekong Region.
My position on hydropower hasn’t changed since the 1990s, and there are several posts on REDD-Monitor that are critical of hydropower.
Had Catanoso wanted to embellish what I said (which in any case would be unacceptable), he could with very little effort have discovered my position on hydropower.
Hydropower is not a solution to climate change
Just over a week ago, International Rivers launched a petition calling on governments, financiers and other institutions to keep large hydropower projects out of their initiatives to address climate change. You can sign the petition here:

A Civil Society Manifesto for the Support of Real Climate Solutions
Large hydropower projects are often propagated as a “clean and green” source of electricity by international financial institutions, national governments and other actors. They greatly benefit from instruments meant to address climate change, including carbon credits under the Clean Development Mechanism (CDM), credits from the World Bank’s Climate Investment Funds, and special financial terms from export credit agencies and green bonds. The dam industry advocates for large hydropower projects to be funded by the Green Climate Fund, and many governments boost dams as a response to climate change through national initiatives. For example, at least twelve governments with major hydropower sectors have included an expansion of hydropower generation in their reports on Intended Nationally Determined Contributions (INDCs).
Support from climate initiatives is one of the reasons why more than 3,700 hydropower dams are currently under construction and in the pipeline. Yet large hydropower projects are a false solution to climate change. They should be kept out from national and international climate initiatives for the following reasons:
- Particularly in tropical regions, hydropower reservoirs emit significant amounts of greenhouse gases. According to a peer-reviewed study, methane from reservoirs accounts for more than 4% of all human-caused climate change – comparable to the climate impact of the aviation sector. In some cases, hydropower projects are producing higher emissions than coal-fired power plants generating the same amount of electricity.
- Rivers take about 200 million tons of carbon out of the atmosphere every year. In addition, the silt that rivers like the Amazon, Congo, Ganges and Mekong carry to the sea feeds plankton and absorbs large amounts of carbon. Hydropower projects and other dams disrupt the transport of silt and nutrients and impair the role of rivers to act as global carbon sinks.
- Hydropower dams make water and energy systems more vulnerable to climate change. Unprecedented floods are threatening the safety of dams and alone in the US have caused more than 100 dams to fail since 2010. Dam building has also exacerbated flood disasters in fragile mountain areas such as Uttarakhand/India. At the same time more extreme droughts increase the economic risks of hydropower, and have greatly affected countries from Africa to Brazil that depend on hydropower dams for most of their electricity.
- In contrast to most wind, solar and micro-hydropower projects, dams cause severe and often irreversible damage to critical ecosystems. Due to dam building and other factors, freshwater ecosystems have on average lost 76% of their populations since 1970 – more than marine and land-based ecosystems. Building more dams to protect ecosystems from climate change means sacrificing the planet’s arteries to protect her lungs.
- Large hydropower projects have serious impacts on local communities and often violate the rights of indigenous peoples to their lands, territories, resources, governance, cultural integrity and free, prior informed consent. Dams have displaced at least 40-80 million people and have negatively affected an estimated 472 million people living downstream. The resistance of dam-affected communities has often been met with egregious human rights violations.
- Large hydropower projects are not always an effective tool to expand energy access for poor people. In contrast to wind, solar and micro-hydropower, large hydropower dams depend on central electric grids, which are not a cost-effective tool to reach rural populations, particularly in Sub-Saharan Africa and the Himalayas. Large hydropower projects are often built to meet the demands of mining and industrial projects even if they are justified by the needs of the poor.
- Even if they were a good solution in other ways, large hydropower projects would be a costly and time-consuming way to address the climate crisis. On average large dams experience cost overruns of 96% and time overruns of 44%. In comparison, wind and solar projects can be built more quickly and experience average cost overruns of less than 10%.
- Unlike wind and solar power, hydropower is no longer an innovative technology, and has not seen major technical breakthroughs in several decades. Unlike with solar power, climate funding for large hydropower projects will not bring about further economies of scale, and does not encourage a transfer of new technologies to Southern countries.
- Wind and solar power have become readily available and financially competitive, and have overtaken large hydropower in the addition of new capacity. As grids become smarter and the cost of battery storage drops, new hydropower projects are no longer needed to balance intermittent sources of renewable energy.
- Hydropower projects currently make up 26% of all projects registered with the CDM, and absorb significant support from other climate initiatives. Climate finance for large hydropower projects crowds out support for real solutions such as wind, solar and micro hydropower, and creates the illusion of real climate action. Including large hydropower in climate initiatives falsely appears to obliterate the need for additional real climate solutions.
For these reasons, the undersigned organizations and individuals call on governments, financiers and other institutions to keep large hydropower projects out of their initiatives to address climate change. All climate and energy solutions need to respect the rights and livelihoods of local communities.
and nuclear? what’s your position on nuclear?
@Hannah – That’s a good question. I’ll write a post explaining my position on nuclear power in the next few days. Spoiler alert: I don’t like it much.
Incidentally (or, actually, not at all incidentally) Justin Catanoso didn’t ask me that question, but nevertheless decided that I was in favour of heavy investment in nuclear power.
Can you report & comment on ITTO’s event w Indonesian negotiator yelling at people today? Thanks!
@carol – Thanks for this. I’d love to, but this is the first I’ve heard about it. Do you have any further details or news reports? How did you hear about this? Thanks!
What’s your position on “run of the river” systems like Inga Falls?
@Russell Gammon – There are two existing dams: Inga I and Inga II. A third dam, Inga III is proposed (cost US$80 billion). Then there’s the proposed 39,000 MW Grand Inga Dam. These are large hydropower projects (Grand Inga would be the largest dam in the world). Problems include corruption and massive social and environmental impacts.
Here’s Peter Bosshard at International Rivers writing about a new paper in Science that slams hydropower:
