Japanese Firms' Bets on Solar Could Take Awhile to Pay Off

Japanese Firms' Bets on Solar Could Take Awhile to Pay Off from the WSJ.

The article is full of good information.

Good quote:
Solar currently generates just a tiny portion of global energy, but that is expected to increase to as much as 37% in 2040, according to the Massachusetts-based Prometheus Institute for Sustainable Development, which follows the industry. It says the market could be worth more than $1 trillion in 2040, compared with $20 billion last year.

Another fact was for Japanese companies such as Sharp, solar is still a small part of their sales and the market is still largely dependent on government subsidies. Since Japan stopped their subsidies, the market growth in Japan has slowed. #1 solar producer is German, #2 is Japanese.
