A fascinating idea is to use solar and wind power to power factories or mining/production sites that are in remote locations - often, that's one of the main limiting factors. The main disadvantage of solar power is that it can't be used 24 hours a day, however besides the expensive batteries, solar power can be stored in other ways - for example, you can use every minute of idle time or free capacity to power compressors that pump air inside a few large tanks, and use that compressed air at night to power the generators.
