Lessons from Scaling Solar in Africa

If you’re inclined to believe that solving things like poverty (in this case energy poverty) just takes a bunch of money and willpower, then I strongly recommend this article. It’s a real-world example of why scaling solutions is hard: complex problems, competing interests, hidden subsidies, and so on.

I do think we’re headed to a future where solar infrastructure becomes the default power solution in much of the world, but this article illustrates what it will take to get there.

The solution seems so obvious. A region synonymous with abundant sun is hungry for more electricity. Given Africa’s colossal untapped solar radiation, the continent should be installing solar panels at a furious pace. But it’s not. Though home to 60% of the world’s best solar resources, Africa today represents just 1% of installed solar photovoltaic capacity.

Giving-Pledge Criminals

Here’s an interesting thought. How many of the Giving Pledge billionaires—those who have promised to donate half their wealth by the time they die—have either been convicted or accused of crimes or other misconduct?

By this analysis, it’s a lot.


  1. I investigate the rates of criminal misconduct amongst people who have taken The Giving Pledge (roughly: ~200 [non-EA] billionaires who have pledged to give most of their money to charity).
  2. I find that rates are fairly high:
    1. 25% of signatories have been accused of financial misconduct, and 10% convicted
    2. 4% of signatories have spent at least one day in prison
    3. Overall, 41% of signatories have had at least one allegation of substantial misconduct (financial, sexual, or otherwise)

Political Speech, Charities, and a New Johnson Amendment

Tax-exempt charities in the US are forbidden from supporting political parties or candidates because of a 1954 law called the “Johnson Amendment.” It’s been a frequent point of controversy over the years because it’s a government-imposed limit on free speech.

Defenders of the law have argued that tax-exemption is voluntary, and if charities want to engage in politics then they can just give up tax exemption. Moreover, tax-deductible political donations could open an economic can of worms. Critics of the law argue that limiting political speech is too precious of a price to demand, especially for religious nonprofits that have doubly enshrined interests (speech and religious activity) in the First Amendment.

Loyola law professor (and friend) Sam Brunson has recently written a paper proposing a moderated, middle way. It’s a novel approach and one worth considering.

This Article proposes an update and replacement for the current Johnson Amendment. The proposed new Johnson Amendment would directly target subsidies, requiring public charities to calculate the value of their political speech and requiring donors to reduce their charitable deductions by their share of such spending. It also proposes safe harbors for public charities that do not want to engage in partisan politics and do not want to have to calculate spending on politics. This new Johnson Amendment would accomplish the putative goals of the current Johnson Amendment without violating the First Amendment.

Happiness in spite of poverty

Overall happiness and income are very closely tied, especially at lower income levels. But a recent, large study revealed low-income exceptions to the rule.

One of the most robust findings in happiness research is the link between income, wealth, and life satisfaction. The more money someone has, the more satisfied they tend to be. The richer a country, the happier its citizens. But as scientists are now learning, some buck this broad trend. People — often indigenous — who live in small, isolated communities tend to be as satisfied with their lives as people living in the wealthiest countries. Finding out why could benefit us all.
