The US Energy Flow for 2015 at this link: http://www.eia.gov/totalenergy/data/monthly/pdf/flow/total_energy.pdf.
Domestic production and imports (in quadrillion BTUs):
- the US produces: 88.63
- the US imports: 23.61
- Sub-total: 112.24
Total US consumption (in quadrillion BTUs): 97.65
US production + imports - exports (in quadrillion BTUs):
- coal: 15.73 (in 2014: 17.92)
- natural gas: 28.32 (in 2014: 27.51)
- petroleum: 35.38 (in 2014: 34.78)
- nuclear: 8.34 (in 2014: 8.33)
- renewable: 9.68 (in 2014: 9.63)
- hydroelectric: 25% of 9.68 = 2.42
- wood: 21% of 9.68 = 2.03
- biofuels: 22% of 9.68 = 2.13
- biomass waste: 5% of 9.68 = 0.48
- wind: 19% of 9.68 = 1.84
- solar: 6% of 9.68 = 0.58
- geothermal: 2% of 9.68 = 0.19
1.84 / 97.65 = 1.9% (wind) [in 2014: 1.77%]
0.58 / 97.65 = 0.6% (solar) [in 2014: 0.4%]
Note: in the US, a quadrillion is a thousand-trillion.
Comments:
I think over time, one will see a "drag" on the energy sector as more and more solar / wind is added to the mix. "Drag" will be seen in the following:
- increased utility expenses for all consumers
- increased non-dispatchable energy requiring increased / redundant / otherwise unnecessary natural gas plants
The Midcontinent fossil fuel industry is going to thrive in a non-dispatchable energy environment. Think about it. All things being equal, electricity supply/demand has been fairly stable / flat over the past few years, I assume. Coal and natural gas "growth" might have flat-lined over the past decade -- I don't know -- but with the addition of non-dispatchable energy, albeit very, very, very little, the US will require additional natural gas plants for "back-up." That "back-up" is not going to come from nuclear power or coal. In fact, hydroelectricity could also be impacted negatively. I don't think there is any energy less expensive than existing hydroelectric power but with political mandates, some states like California will displace hydroelectricity for solar energy (see RBN Energy).
