Efficiency will be measured by price per kwh. If price varies by location, I will use US prices.

I will interpret "new" to mean new technology. I'll be generous in what counts. Windmills won't count, but I would count bladeless wind turbines. I'll define clean by "does not release greenhouse gases." So yes, modular nuclear reactors are on the table.
