I have been thinking about it. Will it make transportation more profitable or food and energy more profitable to go into.
The only one I seem sure of is renewable energy

Not really. But business will adjust prices faster than salaries will

Renewable energy is a financed intensive business. And mind you, it's not a stationed business. Transportation is involved.

You would need to start with something small. But I'll advice you don't just venture into any business because of your search online.

The reasons are because these businesses are very common and highly competitive.

However, you'll need to test your business ability to know what you can do and identify your target market, even at a very low cost to start.

I can be of immense help if you want to know more about starting a profitable business, unique to you...
