Mogg's brief tenure as energy secretary was notable mainly for him proposing a cap on the profits of renewable and nuclear energy providers specifically, having previously been opposed to government intervention in energy markets when oil and gas company profits spiked.

That obviously doesn't mean there's any substantive link between his politics and the Bloomberg study (and he denies being a climate-change denier and supported other policies aimed at encouraging the expansion of renewables anyway) but the context might be helpful to people who don't know who Mogg is
