Canada did pretty well with the feed-in tariffs, but then a lot of those programs and a lot of the contracts were cancelled, which is unfortunate.
A few places that are leading.... Vietnam had one of the most rapid uptakes of renewable energy, starting with solar photovoltaic and then wind. This was because of the alignment of a whole range of regulatory, economic and knowledge support incentives. It had the most rapid uptake of renewable energy ever seen, I think, in a really short period of time.
The European Union is now moving forward with a new understanding of grid distribution by looking at something called renewable energy communities and energy communities. This is looking at things like microgrids, virtual power plants and the clustering of tech in different communities.
