Open thread: British Columbia’s Site C Peace River dam

There’s already a thread on dams and climate change, but B.C.’s Site C project raises many different subjects of interest: how different climate-safe energy options compare, what purposes new generation will be serving, and who gets to make the decisions, with particular regard to Indigenous rights.

Canada and military procurement

Writing for Maclean’s, Scott Gilmore suggests that Canada should “ban the buying of made-in-Canada warships” because politicians have a bad record of fiddling with the process for their own purposes, and shipyards have a poor record of delivering. He presents it as a job protection scheme rather than national security, and a shockingly expensive one:

“But what about the jobs?!” I can hear the lobbyists cry. Yes, let’s talk about the jobs. According to the government of Canada’s own figures, only 11,100 people are employed in Canada’s shipbuilding industry (we have more massage therapists). If we were to add on those indirectly employed, that number creeps up to 15,200. Now, let’s pretend the Canadian frigate contract is the only shipbuilding job out there, and buying from France would mean every one of those 15,200 people would be out of work. If we were to give each of them $1 million in compensation, Canada would still save over $50 billion (in addition to getting the ships faster).

Similar political patterns seem evident in Canada’s long-running imbroglio about replacing fighter jets, though that may have more to do with the nuances of maintaining the Canada-US security relationship than with subsidizing Canadian firms and workers.

Malaria’s lifelong economic impact

Successful campaigns to eradicate malaria have been studied in a number of different countries. Each of these studies compares high-malaria-prevalence regions in the country with low-prevalence regions and checks what happens to children born in this areas before and after the campaign. They all find that life outcomes (such as education or earnings) of children born after the campaign in areas where malaria was once prevalent catch up with those of children born in low-incidence areas. This strongly suggests that eradicating malaria indeed results in a reduction in long-term poverty, although the effects are not nearly as large as those suggested by Jeffrey Sachs: One study on malaria eradication in the U.S. South (which had malaria until 1951) and several countries in Latin America suggests that a child who grew up malaria-free earns 50 percent more per year, for his entire adult life, compared to a child who got the disease. Qualitatively similar results were found in India, Paraguay, and Sri Lanka, although the magnitude of the gain varies from country to country.

Lessons from successful fossil fuel divestment campaigns

Divest Canada — a self-initiated, volunteer-run effort to support fossil fuel divestment campaigns at Canadian universities — recently hosted a webinar on lessons learned from recent successful campaigns:

It is encouraging on several fronts. It’s great to see all these groups patiently implementing strategy on their own initiative and yet in parallel. It brings hope to see the commitment and dedication of the activists. Above all, it suggests that the most important success factor for a divestment campaign is being able to survive long enough for an opportunity to arise with sympathetic administrators, all the while building the intellectual and moral case along with campus-wide support.

Starlink in the Canadian north

SpaceX’s Starlink satellite constellation promises to provide low-latency high-bandwidth internet to anyone on the planet.

In November or so, the company announced a beta release in Canada. Some northern communities are already being connected, notably Pikangikum in northwestern Ontario with the charitable assistance of FSET Information Technology and Service.

With my brother Mica starting to teach at the Chief Jimmy Bruneau School in Behchoko, about 125 km down the highway from Yellowknife, we both wondered whether the satellite internet package might be useful for them.

So far, I have found three explanations for why Starlink isn’t available in the region yet:

  1. SpaceX doesn’t yet have the necessary satellites to support access from that latitude
  2. SpaceX needs ground stations in areas where there will be customers
  3. Starlink needs to negotiate with Innovation, Science and Economic Development Canada (ISED) for use of the Ka radio band

I have reached out to bureaucrats and people in ministers’ offices to try to get authoritative information on what the issue is.

This post — based around this map — shows a station in Kaparuk, Alaska. I sent a message to the map’s creator for verification, since I can’t see how satellites going from pole to pole could cover Alaska but not the Canadian territories. This post shows a Starlink ground station in St. John’s Newfoundland.

If you have any relevant information please contact me. If you are also looking into getting a Starlink connection in northern Canada I don’t have any further information for now but I will provide updates when I do.

UVic’s partial divestment

It’s hard to know what the exact count is when you count partial divestments, but UVic has joined the set of Canadian universities acting on fossil fuel divestment by transferring $80 million to a short-term bond meant to reduce the CO2 intensity of their portfolio.

All told they have about $225 million and they have pledged to reduce the carbon intensity of the portfolio by 2030. I don’t know if the carbon intensity of a portfolio is really a meaningful idea (how do you divide responsibility for Boeing’s emissions between shareholders and customers, for instance?). I’m likewise skeptical about targets set beyond when the current leadership will hold power.

The hope with divestment is that universities would be persuaded by the arguments that investing in fossil fuels is unethical and financially dubious. Universities have found many ways to act which fall short of condemning the fossil fuel industry and withdrawing all financial support. These precedents arguable erode the case for action, since they substitute the idea that the fossil fuel industry is uniquely dangerous and unworthy of support with the idea that essentially business-as-usual investment management can somehow deal with the problem of climate change.

Heat pumps

David Mackay’s Sustainable Energy — Without the Hot Air emphasizes heat pumps as a decarbonization tool:

Notice that heat pumps offer a system that can be “better than 100%- efficient.” For example the “best gas” power station, feeding electricity to heat pumps can deliver a combination of 30%-efficient electricity and 80%- efficient heat, a “total efficiency” of 110%. No plain CHP [combined heat and power — where waste heat from energy production is used for heating] system could ever match this performance.

Let me spell this out. Heat pumps are superior in efficiency to condensing boilers, even if the heat pumps are powered by electricity from a power station burning natural gas. If you want to heat lots of buildings using natural gas, you could install condensing boilers, which are “90% efficient,” or you could send the same gas to a new gas power station making electricity and install electricity-powered heat pumps in all the buildings; the second solution’s efficiency would be somewhere between 140% and 185%. It’s not necessary to dig big holes in the garden and install underfloor heating to get the benefits of heat pumps; the best air-source heat pumps (which require just a small external box, like an air-conditioner’s) can deliver hot water to normal radiators with a coefficient of performance above 3.

There is also some evidence now that US house owners are sufficiently mindful about long-term energy costs to see their economic advantages reflected in house prices. In Nature Energy Xingchi Shen et al. conclude: “Residences with an air source heat pump enjoy a 4.3–7.1% (or US$10,400–17,000) price premium on average.” (See also)

Some of the usual impediments to environmental retrofits apply here. You generally need to pay for the system up front and then recoup savings over a long period, which means you need to be able to finance it initially. Also, there can be a lack of coordination between renters, landlords, and building owners. Still, technologically heat pumps are promising and we need non-fossil alternatives for building heating and cooling.

Plastic without fossil fuels

Alongside the staggering challenge of replacing the 85% of global energy that currently comes from fossil fuels, humanity must also reckon with how the critical systems which we depend on rely on fossil fuels as inputs. We need to learn to make steel without coal and fertilizer without natural gas.

We also need something aside from fossil fuels as a feedstock for plastics, which are now indispensable in every area of human endeavour from spaceflight to surgery. Research of the sort is taking place. For example, Professor Shu-Hong Yu’s team at the University of Science and Technology of China (USTC) has produced non-petroleum based plastics which are twice as strong and tough as engineering plastics.
