Six hundred million people in Sub-Saharan Africa do not have modern energy -- so African nations are working to develop their energy resources. For many, the energy they do have comes from hydro. But Africa also has huge volumes of natural gas. Some funders, concerned about emissions, don’t want them to develop it. Others consider it essential to lift Africa’s people out of poverty.

There are many paradoxes in climate and energy: people want energy for their homes and cars… but don’t want new power lines or pipelines that could provide it. Nuclear is a zero-carbon energy source… yet many climate advocates oppose it. Some states impose EV mandates… but prohibit mining for battery metals. We’ll look to resolve these with two experts in economics, energy and climate policy.
