admin answers:
At 60 degrees latitude (north or south), and averaged over a year, the solar energy level is about 50% to 55% of the level at the equator. That’s not counting the effects of clouds.
A lot of the thermal energy at high latitudes comes in on wind and water movement; I guess you could say that is also a very indirect solar energy.
Helen asks…
Why is solar energy a renewable resource and also some advantages and disadvantages of using solar energy?
Please tell me some disadvantages and advantages of using solar energy. I also need to know why it is a renewable resource. Can you also tell me how much of of solar energy is left and how long it will last. Thank you so much. [Tell me some websites to vist about this information]

First, its all a guess but the sun will continue to shine for about another 2-4 billion years. So for all practical purposes, its eternal.
Solar energy depends on sunshine, one disadvantage is cloudy, overcast, rainy, snow etc. Days. No sunshine, no real energy. Another difficulty is converting solar energy, solar panels generate direct current (DC) and this has to be converted to AC current to run appliances, etc. In your house. In order to store solar energy, batteries are required, so the DC current from the solar panels can charge the batteries, and then the DC current must be converted to AC.
Solar panels are not cheap but the price is coming down. They also don’t last forever and can be damaged by hail, etc.
The good news is, solar energy is clean, not pollution except for the manufacture of the panels and for the moment, sunshine is still free.
