Across the industry, theres a movement to make the energy grid smart. This means that were using technology (adding layers of intelligence, multi-way communication) to make the grid:Self-healingSelf-balancingSelf-monitoringOur CEO, Dick Kelly, has been a forward-thinker in our industry and has accepted the fact that we have to change the way we do business in order to address global climate change. Our companys leadership believes a comprehensive approach is needed to address climate change today. That includes finding new ways to increase our use of resources that produce lower or no CO2 emissions, increasing green energy options for customers, and exploring new generation technologies that could reduce environmental impactsSeveral needs are driving utilities R&amp;D efforts. Consider the fact the gridas it was built in the mid-centurywas not designed to to support homes with air conditioners, high-definition TVs and computers for each family member.And in Minnesota, legislation requires utilities like Xcel Energy to have 25% of their generation come from wind energy conversion systems by 2020. (Minnesota Renewable Energy Objective)Renewables are key to making this happen. We serve areas that are among the best regions for harnessing wind energyand this makes wind an even more important piece of the Smart Grid puzzle.</p></li></ul>
