The relative price of fossil fuels and renewables is key to anyone’s decision of which power plant to build. Making low-carbon technology cheap is a policy goal that doesn’t only reduce emissions in your own country but in the entire world, forever.

Driving down the price of low-carbon energy should be seen as one of the most important goals (and achievements) of clean energy policy, because it matters beyond the borders of the country that is adopting that policy. This is the beautiful thing about technology: once it is invented somewhere it can help everywhere.
