Speaking of misleading, your Bill Gates analogy is quite misleading too. These figures about new electric power are sums over a quarter-year, so small statistical fluctuations like finding a penny (or opening a single power plant) are smoothed out. To complete the analogy, if Bill Gates' biggest source of new wealth this quarter and last quarter were finding pennies, that would be quite a big deal, because over that period he would have to find hundreds of thousands of tons of them - more than doubling US zinc production in the process.
