Your Questions About Sustainable Energy For All

Would solar panels on the roof of every building solve our energy problems?

I know a few people around here who have used government grants to help install solar panels on their roofs. Given that this is the UK and sunshine is a rare commodity here, they still manage to produce more energy than they use, and actually get a small rebate each year from selling off excess electricity back to the National Grid (our national power infrastructure).

Are there reasons why this can’t be adopted globally? Are solar panels difficult to mass-produce (I imagine they use a few rare-earth elements in there somewhere) or is it just down to a lack of willpower to embrace sustainable energy? How well would the technology scale up from powering individual households to powering energy-hungry manufacturing industries?

I’m not expecting an answer to all those, but I’d like to hear opinions from anyone who might have some knowledge of how it works.

Thinking of changing my major from International Business?

I am currently enrolled in college and am thinking of changing my major from International Business, to Global Marketing or Global Finance. Which major offers better pay, working conditions, etc? . I would like to get into sustainable energy, but I do not think I have the math aptitude for engineering. Which of these degrees is in more demand these days?
