All authoritarians are bad at math. Many of them just incompetent and the moment they open their mouth and speak in areas that require quantification, they fail often.
This time is not exception. Who does Hillary has in her presidential team? Liberal art majors?
Here is the calculation:
One solar panel generates approximately 200 Wh of energy. Some might say solar panel generates 230 Wh, but for the sake of simple and easy to understand calculation let's use 200 Wh. There will be 500 million of them.
Let's say there will be 4 hours sun in one day, called Peak Sun hours, a factor which need to be taken into account when making this calculation. Let's say there will be 365 days in a year.
Total energy will be generated per hour: 500 million panels times 200 Wh= 100,000 million Watt hours, or 100,000,000,000 Wh, or 100,000,000, KWh, or 100,000 Mega Wh, or 100 Giga Wh per one hour. My math is correct so far. Right? Per year total energy to be generated 100 GWh X 4 hours x 365 days in a year = 146,000 GWh = 146 TWh.
146 TWh, is the output of 500,000,000 of solar panels
Total energy consumed in USA in 2009, is approx 25,000 TWh per year, here is the source https://en.wikipedia.org/wiki/...
So Hillary is proposing to install solar panels that will be 0.5% of overall energy consumption?
Calculating energy in solar panels, is just as bad as scaring the world with Iran's 100,000 centrifuges, or measuring volume with Olympic size pools.
Yeah. Authoritarians are often bad at math and they are bad this time also.
0.5 % is of course better than nothing, speaking in absolute terms, but the same, or more, can be achieved by many other alternatives.
