Answer:
about 2-3 years
Explanation:
Because Wind and Solar energy store power and when they store that power it becomes reusable. For example, your house runs out of power in a thunderstorm and the lights go out, what can you mostly rely on, Solar Panels and if it has been cloud all day or all week there might be a chance that you run out of power depending how much power the solar panel has but as long as you don't use much power and the whole week has been sunny, you're fine.
