seeing variation that we can tap into — if the sun is not shining here, the wind is blowing there. if it's very hot and sunny here, you've got hydropower or wind power, in another region. connecting us will be a very big part of that. the second part that's quite related is demand response. so how can those who are transmitting and distributing this electricity get signals back from industry or homes that they can, without the user noticing, reduce the load, either change the — turn off the defrost cycle of the freezer for 15 minutes, not even noticeable. 0r reduce the temperature of a cooling. these are the types of responses that we are going to have to get used to, it's not central hub and spoke, we're all part of this new electrical system together and having us connected and having there be signals going both ways from generation to load is going to be a part of making it a more efficient global system ultimately. thank you so much.
