7 impressive solar energy facts (+ charts)
Solar power is in a tremendously different place today than it was in 10 years ago. Below are a handful of impressive stats about solar power’s growth, as well as some general stats about solar energy potential that are also quite noteworthy.
1. Even yearly energy potential from sunshine dwarfs total energy potential from any other source.
The annual energy potential from solar energy is 23,000 TWy. Energy potential from total recoverable reserves of coal is 900 TWy. For petroleum, it’s 240 TWy; and for natural gas, it’s 215 TWy. Wind energy’s yearly energy potential is 25–70 TWy.
2. Approximately 66% of installed world solar PV power capacity has been installed in the past 2½ years.
Furthermore, total installed capacity is projected to double in the coming 2½ years.

3. Global solar PV power capacity grew from about 2.2 GW in 2002 to 100 GW in 2012.
From 2007 to 2012, it grew 10 times over, from 10 GW to 100 GW.

4. There are now about 1.36 million jobs in the global solar PV industry.
There are also about 892,000 in the solar heating & cooling industry.

5. Germany accounted for nearly one third of global solar PV capacity at the end of 2012.
Italy (16%) and Germany (32%) combined accounted for nearly half of global solar PV capacity.

6. The price of solar PV panels dropped about 100 times over from 1977 to 2012.
Since 2008, the price of solar PV panels has dropped about 80%.

7. The sunshine hitting Texas in one month contains more energy than all the oil and gas ever pumped out of the state.
Nonetheless, New Jersey has about 10 times more solar PV power capacity installed than the entire state of Texas.
