The sun is a remarkable abundant, clean, and renewable form of energy, and it’s just within the last 20 or so years that solar panels, inverters and batteries have evolved from an efficiency standpoint to the point where we are beginning to see more homes and some businesses powered 100% with solar energy.
Solar is undergoing widespread and rapid growth in the U.S. and world. The Solar Over Louisville: 2 million watt Solar Challenge is designed to help Louisville optimize its use of solar energy. Solar energy is a proven technology and the price of solar panels is at its cheapest time in history.
Louisville has good solar resources. Yet Louisville and Kentucky currently lag behind other cities and states in joining the soaring rates of solar installations underway in this country and the world. We can change this!
Unleash the creativity and innovation for which Louisvillians are known. Louisville will benefit in multiple ways by creating a more diversified energy mix that expands its reliance on solar energy, energy efficiency, and other renewables. Many believe it will save the city money. It will also create local jobs, cut carbon emissions, improve air and water quality, enhance health, increase energy security, and protect the city’s economic draw as the world around it shifts toward greater use of clean and renewable energy technologies.
There is another good reason to speed up the timeline for installing solar. The thirty percent (30%) federal investment tax credit (ITC) for solar systems is set to expire at the end of 2018. If it does expire, the costs will go up and homeowners and businesses will lose a valuable opportunity to “go solar.”
Consider Germany, the fifth largest economy in the world, which has a climate comparable to Alaska and now routinely produces 30% of its energy from solar and as high as 50% on optimal days. A Solar Energy Industries Association (SEIA) report found that in the first three quarters of 2014, more than one-third (36%) of new electricity capacity in the U.S. came from solar energy. Yet a recent research study found Louisville to rank low among America’s largest cities in solar-friendly policies and rates of installation. Now is a great time for homeowners and businesses in Louisville to decide to “go solar.”
