I recently "ran the numbers" and here is what I found:
#1 -The earth's surface receives a constant 89,000 TerraWatts of solar energy.
#2-Total energy usage by humans is 15 TerraWatts
#3 Now assume that we could cover at most 5% of the earth's surface with solar collectors and they would have a maximum efficiency of 50%, the 89,000 TerraWatts becomes 2,200 TerraWatts.


Welcome and thanks for the comments. I added numbers.

#1 Isn't the Earth about 65 to 75% water? Are you suggesting we float solar collectors?

#2 Will energy use go up faster than we build solar panels?

#3 If I fly over the US, I am struck that it seems most of the land is open space. Far less than 5% of the US is buildings. I assume the rest of the planet is the same or less. Thus, even if you were talking about covering 5% of the land mass with solar, it would probably mean doubling the number of buildings and roads to service what we have now. Of course, it is a good idea to put solar on top of what we already have if cost effective, but I don't see solar replacing oil and NG but Nuclear has that potential.

Bob Brinker wrote in the January 2008 Marketimer with S&P500 @ 1468.36:

In summary, the Marketimer stock market timing model indicates that conditions are favorable for the market as we enter 2008."

And

"We expect the S&P Index to achieve new record highs this year and to reach the 1600’s range in the process. “

The S&P500 was just in the 1100's



Bob Brinker has been fully invested since March 2003 and specifically recommended on the radio against rebalancing his 50:50 portfolio even when it was way out of balance favoring equities.

I disagreed with that advice in that I recommend rebalancing portfolios once a year at a minimum since you don't want your 50:50 balanced portfolio to get too over weight to equities and subject retired people to a major decline. You can easily do the rebalancing with your tax deferred accounts.
