Prepping - Are you prepared for the Grid to go down ?

Good morning guys so we’ve got the dogs up at windfarm for the walk and when I was walking past the wind turbines made me think of the good weather to go down for 24 hours 40 hours or even for a week would you be ready?

Would you be able to make a hot drink, would you be able to heat up food or would you have the ability to provide light and warmth
