Manufacturing Sector Energy Use Improvement

Posted April 12, 2013 12:00 AM by Milo

Significant decline in energy use and intensity by manufacturers show improvements in both energy efficiency and changes in manufacturing output mix.

The US Energy Information Agency released data March 19th documenting a 17% decrease in total energy consumption by the manufacturing sector from 2002 to 2010.

Manufacturing output only declined by 3% over the same time period.

Interestingly, the decline in consumption was noted for all fuels.

What is your shop doing to decrease your energy consumption?

It would be interesting to correlate those data with that from other countries.

Try this web site, it covers all counries and basically covers all energy uses. Just type in the country or click on the link and it gives you the country. Covers hydro, oil, wind, marine, nuclear, oil consumption etc etc. Handy as a quick reference. Cheers.

During the time 2002 to 2010 there has been a push by the US government for manufacturing to reduce energy usage. Programs have been set up to provide funding for outside consulting for manufactures to find ways to reduce there consumption. Low interest loans were also provided for any changes.

My company was a recipient of one of these programs. They tested all the equipment to find a means to reduce consumption. In the end the lighting and our heating system was changed.

Even the plastic protective packaging industry is moving towards completely bio-based products. The volume of oil used every year in the production of plastics equates to approximately five per cent of the world's total oil consumption. Approximately 40 per cent of all plastics are used in packaging, which puts special pressure on the packaging industry to reduce dependence on oil.

"Lies, damned lies, & statistics" is a quote by Winston Churchill, implying that statistics are far worse than lies or damned lies. (Weapons of Mass Destruction excluded)

US industrial output is measured in US$. US industrial energy consumption is measured in kilowatt hours.

Over 8 years the $ has been subjected to inflation so increasing the perceived value of industrial output. A kWhr was measured the same in 2010 as 2002.

The figures shown do not take into account a change in the manufacturing mix. Low added value heavy energy users like the US steel industry, and bulk chemicals have declined at the expense of increased imports. High added value light energy users like aircraft assembly have increased exports to compensate.

This looks to me like a Government Agency massaging the headlines for public consumption by choosing what to quote.

Hi jhhassociates.

Thanks for the critical thinking regarding the denominators applied.

I've been out producing our trade show PMTS in Columbus Ohio and finally caught a chance to sheck back in.

I think that you are on to something worth a closer examination.

Much obliged.

Milo
