Green

As the baby boomers retire they take their capital with them. Instead of investing in stocks they move their money to government bonds which means the cost of capital will rise because there is less of it. This has an adverse effect on going green. When a new natural gas power plant is built the cost is spread over the life of the project because it is financed with user fees. Only 20% of the cost is in the construction and the remaining 80% comes from user fees. When windmills and solar farms are constructed all of the cost is up front since there is no later fuel cost. As capital becomes more expensive it makes the cost of wind and solar more expensive.
