Clean energy:
Hawaii has an 80% renewable portfolio mandate set for 2030, which means 20% fossil fuels with the balance of power generated by wind, solar, geo and wave power. Then there is smart grid (scaling power demand & supply via software) and fuel cells (collecting wind/wave power and delivering it into the grid). This industry is where the jobs are going to be for the balance of this century.
Investment Banking:
Think there will be a solution to the unemployment problem without the investment banks? Investment banking is the most misunderstood job out there right now. If I lead a team that can $400m of growth capital for a company with $50m in sales and that company can use that capital to hire a new sales team, then the banks have earned their fees. IB is a tough job but pay your dues and you will be well compensated and afford annual big ticket surf trips. Travel with companies that have a banking relationship with you and the expense is minimal.
