Energy production is up and yet, with changes in the energy mix usage is down. The effect on energy use gradually reducing has implication across the energy sectors. The grounding of “Renewables Inch Up As US Trims Total Energy Use” is a positive sign of gradual changes in the energy mix.
Renewables continue to operate under resiliency steadily growing and expanding. The renewable mix is small yet, gaining ground as other energy change under the weight of demand and infrastructure. Solar rose 48 percent from 0.158 to 0.235 quards, and wind’s contribution rising 16 percent, from 1.17 quads to 1.36. Together, wind and solar mustered 1.6 out of 95.1 quads used in 2012, or 1.67 percent of the energy consumed, up from 1.36 percent in the previous year,” reported Earth Techling.
“Coal was the big loser, as mentioned (down from 19.7 quads to 17.4), as electricity generators switched to cheaper natural gas. The vast bulk of the increased natural gas used in 2012 went into generation (as opposed to home heating use). Another electricity source that declined in 2012: nuclear.”
Coal continues to be shrinking but its dominance is persistent. Natural Gas continues to grow across various states. The growth of natural gas pipelines is ever expanding. “Three of the four sectors – residential, commercial and transportation – used less energy in 2012 than in 2011, with industrial alone seeing an increase (from 23.6 to 23.9 quads). The drop in residential use was particularly striking, falling 7.5 percent, from 11.4 to 10.6 quads.”
The indicators are also based on the supply chain and the efficiencies that are being implemented across the states. The dynamism of energy reduction is opportunity for states to consider infrastructural changes beyond the Consent Decree. The model of production and use are complex but usher in order of commitments and changes for capacity building in energy in the short-long-term.
