Based on the electrical usage of the average Las Vegas hotel, a hotel like the MGM Grand consumes at least 400,000 megawatts of electricity annually. Therefore, the minimum electric bill runs at least $100,000 each month, as of 2014. However, in the interim, the MGM Grand, as well as other hotels along the strip, have initiated green initiatives to reduce electricity and water usage.
According to Southwire Blog, the state of Nevada, in 2012, was rated second in the United States with respect to geothermal and solar power usage. The state is also home to more LEED-certified structures than any other place in the country. LEED certification indicates that a building is designed with sustainability and conservation in mind. Between 2010 and 2014, the city slashed its energy demand by 20 percent by developing energy-efficient structures and replacing street lighting and traffic lights with LED bulbs.
The MGM Grand has also initiated energy conservation in a variety of other areas, including energy-efficient lighting upgrades in its landscaped areas and parking garages. Its managed to save over 14.6 million kWh of electricity each year since implementing the green program in 2006. As of 2014, the amount of power consumed since that time is equivalent to the electricity used annually by 1,200 average-sized homes.
