2,500,000 Gwh
Correct Answer
A. 4,000,000 GWhExplanation
4 million GWh. A gigawatt (GWh) is one billion watts. For comparison, an incandescent light bulb may use about 60 watts of energy. So 4 million GWh is 4 million billion watts! In 2007 California's total energy demand was 285,000 GWh. The available renewable energy in the 11 western states could supply CA, the world's eighth largest economy, more than 14 times over in a clean and sustainable manner.Rate this question:
