Powering the world economy: Is there a better way to use electricity?

Powering the world economy Is there a better way to use electricity? The world has a bottomless appetite for electricity 35,17 World electricity consumption in trillion KWh 28,27 31,64 25,02 +84% 21,9 by 2050 2015 2020 2025 2030 2035 Much of this electricity is used to power industrial electric motors 42% 2/3 = 28% of all electricity used powers industry Global electricity consumption of this is used by electric motors electric motors However, using technology already available today we can make millions of motor systems more efficient 60% Energy efficiency measures can reduce consumption by up to: 44444444444444444 The industrial energy challenge 300'000'000 industrial electric motors are economic growth = more electric motors currently installed worldwide. This figure increases by 10% each year. Approximately 50% of these motors are installed in the US, EU and China. O+10% 50% O+10% of all electric motors are installed in: O+10% +1 year +1 year +1 year +1 year USA EU China 300,000,000 industrial electric motors worldwide today 90% of installed motors run continuously at full speed and use mechanical systems to regulate output. That's like driving with your foot on the accelerator while using the brake to control speed. Opportunities for efficiency Smart motor control systems (called variable speed drives) use only as much electricity as is necessary to do a job, saving enormous amounts of power Smart motor control systems alone could save power output of 1,718 286 billion KWh nuclear reactors Improved design can also increase efficiency of individual motors by 30%4 up to Savings are gradually being realized In comparison EU regulations which require a switch to energy efficient light bulbs will save 40 billion KWh 2011 2012 2013 2014 2015 2016 2017 2018 2019 2020 135 billion KWh 135 Newly introduced EU efficiency legislation will speed up the adoption of these measures, saving billion KWh 40 billion KWh Schemes in other regions including US legislation in place since the 1990's have also brought significant savings What does this number really mean? 135 billion KWh = %D akilosho's Enough to power the city of Los Angeles for almost 2 years Enough energy to run a German high-speed ICE train at 300kmh for 1,500 years 27,000x the amount of An electricity bill for this amount of energy would equal €12 billion or wind energy capacity installed in the United Kingdom (in 2010) $17 billion What are we waiting for? 1-3 Electricity is expensive - a 150 kilowatt pump motor running 6 days per week for 50 weeks uses around $75,000 (€50,000) worth of electricity per year For electric motors average electricity costs = 92% of life- time operational costs. Energy efficiency measures typically pay for themselves in 1 to 3 years payback 2$ years. $75,000 60% Despite the potential for significant long term cost savings, a recent report commissioned by ABB and carried out by the Economist Intelligence Unit found that: of businesses have not undertaken any measures within the past 3 years to improve energy efficiency Possibly 46% Possibly 42% because because of businesses believe of businesses have no companywide energy management system to track and optimize there is no clear-cut financial case for such measures energy use Energy efficiency pays for itself If all countries adopted a comprehensive policy package for electric motor efficiency then by 2030 annual energy savings would equal 2,800 TWh (per year) The total saving between now and 2030 would equal $1.75 trillion (€1.2 trillion) - more than enough to cover the required investment This saving is equivalent to the yearly electricity output of 466 nuclear reactors - a little bit more than today's total nuclear capacity If we implemented these measures as fast as technically possible we could practically double the savings: $2.9 trillion (€2 trillion) That is approximately equal to total write downs resulting from the 2008 banking crisis 2.

Today, the European Union is introducing new legislation which marks an important step in realizing some of these benefits, and which further highlights the potential to drastically reshape the world...
