    Energy Challenge

    As the world continues to develop, the demand for energy is increasing; NOV is providing products and services to meet this demand. Internally, NOV is actively managing energy consumption by creating a company-wide energy profile and implementing energy efficient measures, as appropriate, to meet our stated goals. NOV continues to push its initiatives to collect the necessary information of the company’s energy consumption. We continue to refine and develop our practices for estimating NOV’s energy use and are dedicated to our energy goals.

    1 Includes Grant Prideco and ReedHycalog (does not include other acquisitions in 2007).
    2 Only includes facilities active December 2013.
    3 Only includes facilities active in December 2014, therefore does not include DNOW facilities spun off mid-year.
    4 As the company has evolved, so has the emissions calculation approach. All estimated emissions in this chart reflect a revised calculation approach implemented in 2014. Historical numbers were recalculated using the modified approach.

     

    Within the past few years, NOV has developed systems to track and reduce our energy use. The NOV Energy Use Survey was created specifically to record monthly electricity, natural gas, and fuel usage at every facility and provide an accurate picture of NOV’s overall energy consumption and meet global greenhouse gas emissions reporting requirements. We will continue to monitor legislation and report as necessary.

    The largest obligation is in the United Kingdom, where energy laws were put into effect under the Carbon Reduction Commitment Energy Efficiency Scheme (CRC). After much debate, the Environmental Agency, through the CRC, has essentially implemented a tariff on carbon emissions. NOV successfully reported in July 2012 and July 2013 to the UK Environmental Agency and has met all its obligations to the CRC to date. We are continuing to monitor our energy use and implementing reduction measures. In the United States, NOV successfully reported to the EPA for the Greenhouse Gas Mandatory Reporting Rule for the facilities that have mandatory obligations by the April 2012 deadline. All facilities in the United States have been evaluated for applicability to regulatory obligations and reported on as necessary. The Australia legislature recently passed the Clean Energy Legislation to track and price greenhouse gas emissions beginning July 1, 2012.

    Improving Energy Efficiency

    In addition to meeting all our greenhouse gas and energy use reporting requirements, we are committed to improving the energy efficiency of our operations. Energy efficiency and green technologies are part of the considerations taken when building new facilities and remodeling older ones. Energy efficiency building requirements and regulations are being met for our new facilities in England and Scotland; these requirements are also being used as recommendations and considerations for new facilities and developments in Brazil, the United States, and other locations we operate.

    NOV has also formed a global energy team to perform energy audits on the individual facilities. These energy audits have revealed multiple measures that can be taken across the global enterprise to increase energy efficiency and reduce NOV’s overall energy consumption and spending as well as facility-specific reduction opportunities. To perform these energy audits, the corporate energy team works in conjunction with a target facility and analyzes equipment, lighting, HVAC units, and energy consumers to develop a report outlining the facility’s largest energy consumers and recommendations for reduction and efficiency improvements. Recommendations range from suggestions and improvements as simple as cleaning skylights to allow for brighter facilities and the possibility to eliminate some artificial light use, to purchase efficient HVAC units or even improve process designs.

    LED lighting uses a fraction of the power that traditional light fictures use. However, Improvement in LED technology has enabled NOV to utilize LED lighting in our manufacturing facilities. Since 2010, NOV has retrofitted numerous facilities in the United States, Canada, and China with LED lighting. Additional, many newly constructed facilities utilize LED lighting.

    At one of NOV’s facilities in Stonehouse, England, engineers and the HSE group have teamed up to design a system that would capture waste heat generated by their energy-efficient HVAC units and recycle it back into the building. The system is set to a thermostat so it only recycles the heat at appropriate times, alleviating the amount of energy needed to heat the building during cold months as well as eliminating wasted heat generated.
