Yes, there certainly are.
One example would be the renewables obligation. All utilities in the United Kingdom now must have a rising percentage of renewable energy in their energy mix. Every year, that goes up by 1%.
We start from a very different position than Canada does. We have almost no hydro, and we depended very heavily on coal 20 years ago. So we start from less than 2% renewable, whereas I think Canada is at around 70%.
But we are driving that up as fast as we can, and that's being done through a renewables obligation. There's an obligation on utilities to have a rising percentage. They combine that energy, too; they can get some government subvention for energy that's created with renewable energy.
That has done a lot to stimulate the market. People producing renewable energy, whether it's solar or wind or tidal or biomass, know that they have a ready market for that and will be able to sell it, and sell it at well above normal market price. That is already driving behaviour.
